What Is Thiamine For Alcoholics?

What Is Thiamine For Alcoholics
Alcohol related thiamine deficiency – Alcohol and Drug Foundation

  • Thiamine, also known as vitamin B1, is an essential nutrient used by the body to convert food into energy.
  • Thiamine takes the fats, proteins and carbohydrates we consume and uses them to fuel functions of the heart, nerves and brain.1
  • Because the body cannot produce thiamine, it must be consumed through foods like:
  • whole grain products such as cereals, rice, pasta, and flour
  • wheat germ
  • beef and pork
  • trout and bluefin tuna
  • eggs
  • legumes and peas
  • nuts and seeds.2

Smaller amounts of thiamine are present in fruit, vegetables and dairy products.2 Thiamine is also added to food products like bread and is available as a dietary supplement.3

How does thiamine help with alcoholism?

In millions of households across the country, bottles containing multivitamin tablets sit next to the toaster, on a cabinet shelf next to the sugar or some other handy location. They’re a staple for people who want daily diet supplements. Among the familiar substances in those bottles is a secret weapon that also helps people ravaged by alcohol use. CeDAR nurse Gene Shiling developed a protocol to give vitamin B1 –to alcohol users to prevent a type of brain damage called Wernicke encephalopathy. It’s vitamin B1, or thiamine, a substance that plays a key role in converting the foods we eat into energy.

  1. Most people get plenty of it through their diet or those multivitamin supplements.
  2. But thiamine has a small number of enemies.
  3. One of them is chronic alcohol consumption, which often leads people to poor nourishment.
  4. That means that the body gets less thiamine and also has greater difficulty absorbing and utilizing what it gets of the vitamin.

Thiamine deficiency, in turn, can lead to acute Wernicke encephalopathy, a form of brain damage that causes confusion, vision problems and difficulty moving. The good news is there is a quick, inexpensive treatment for it: intravenous infusion of thiamine as soon as possible after the symptoms appear.

Screening alcohol-use patients for Wernicke encephalopathy and treating those at risk with IV thiamine is now an established protocol at the UCHealth Center for Dependency, Addiction and Rehabilitation (CeDAR) on the Anschutz Medical Campus, thanks in large part to the work of CeDAR nurse Gene Shiling.

Thiamine time Shiling developed the protocol as a credentialing project for UEXCEL, the professional development ladder for nurses at UCHealth University of Colorado Hospital, It began when he looked at gaps between the time CeDAR admits patients and the time physicians enter orders that initiate treatment.

  • He wanted to be sure that all patients admitted for alcohol use who could benefit from Vitamin B1 received it as quickly as possible.
  • Shiling was eager to work on the problem because Wernicke encephalopathy is completely reversible once patients receive IV thiamine.
  • In the past, providers often looked for all three of the main symptoms – loss of control of bodily movements, confusion and vision problems like nystagmus (rapid, uncontrolled eye movements) – before giving patients treatments.

New research shows treatment is beneficial even if patients have just one symptom. Most importantly, the treatment saves brain function and can help to stave off the even more serious Wernicke-Korsakoff syndrome, which permanently damages the brain. “Thiamine is easy to get and it’s relatively inexpensive,” said Dr.

Daniel Bebo, an addiction medicine specialist at CeDAR. “But the effect of Wernicke encephalopathy and Wernicke-Korsakoff is brain damage. The end result is patients can become non-functional.” High-risk population To illustrate the significance of thiamine treatment in CeDAR’s patient population, Bebo noted that Wernicke encephalopathy appears on autopsy – the only way to definitely diagnose it – in between,4 percent and 2.8 percent the general population.

For heavy alcohol users, it’s about 12.5 percent, and in those who die alcohol-related deaths, it ranges from 25 percent to 59 percent. Given those numbers, Bebo said, “It’s curious that thiamine deficiency is still undertreated.” Indeed, Shiling said in his research for the UEXCEL project that he couldn’t find another substance use disorder facility anywhere in the country that follows an IV thiamine protocol like the one that he helped to put in place at CeDAR.

  • It includes screening all alcohol-use patients for Wernicke encephalopathy and administering IV thiamine within the 72-hour window to all who exhibit at least one of the three indicators or who are too intoxicated to be screened.
  • In addition, Shiling designed training in recognizing Wernicke encephalopathy for all CeDAR nurses and physicians and a tool for assessing the condition that is now in the Epic electronic health record.

He also successfully advocated for adding thiamine to the initial order set for physicians. Payoff for patients The results of the work were significant. After implementing the protocol, Shiling analyzed three months of data and found that of 57 patients admitted to CeDAR for alcohol use disorder, 22 received IV thiamine.

Another five met the screening standard but did not receive the therapy for a variety of reasons, he said. It’s difficult to identify definitively the benefits of the treatment, but for Shiling the “probable consequences” of thiamine deficiency have been on display during his seven years as a CeDAR nurse.

“We frequently see patients after detox, inpatient care, counseling and multiple modalities of treatment who still have cognitive deficits, but we can’t figure out what they are,” he said. In the wider world, Shiling added, the damage caused by Wernicke encephalopathy ranges from increased difficulties for individuals working in fields like accounting and law that require high-level cognitive ability to a complete loss of executive function in the most serious cases.

  1. Shiling and Bebo pointed to the case of a patient who arrived at CeDAR severely intoxicated and exhibited “the classic triad of symptoms” of Wernicke encephalopathy, as Bebo put it.
  2. The patient received IV thiamine treatment within one hour, helping to lead to a positive outcome.
  3. Our concern was that he would lose cognitive ability, but he walked out just fine,” Bebo said.

What if the Wernicke encephalopathy diagnosis is wrong but providers initiate treatment? Well, nothing. If a person gets too much thiamine, the body simply gets rid of it through the call of nature. “If we give thiamine to a whole bunch of people who don’t really need it, there is no harm done,” Shiling said.

  • It’s also inexpensive, he noted.
  • The total cost of the thiamine and supplies to administer it is $89 for a total of six 500-milligram treatments delivered three times a day for two days.
  • At CeDAR, we’ve said, let’s go ahead and be aggressive,” Bebo said.
  • Gene’s role was to recognize the need and implement a policy that we have adopted.

He has also opened up the view to others at CeDAR of research being really important.” Professional and personal interest The project seems to have opened an avenue of interest beyond CeDAR. Shiling presented his work in early October to the annual conference of the International Nurses Society on Addictions and said he received a good response.

  1. He’s also submitted it to the American Society of Addiction Medicine and to the UCHealth-sponsored Rocky Mountain Interprofessional Research and Evidence-based Practice Symposium, which will be held next spring.
  2. The commitment Shiling has made to patient care also has a personal component.
  3. He was a patient at CeDAR in 2009 for treatment of a heroin addiction.

In July 2019 he looks forward to celebrating a decade of sobriety. “I feel like I can relate to our patients on a personal level,” he said. “I know what it feels like to be in their shoes, what it feels like to have to give up control and surrender, to take advice from strangers and have people tell you how to live your life and how difficult that is.” His commitment has not gone unnoticed at UCHealth.

  • It’s very exciting to see the impact our clinical nurses are making with patient outcomes when they lead quality improvement work,” said Danielle Schloffman, director of the Magnet Program for nursing at UCH.
  • One goal of the UEXCEL credentialing program is to support direct care nurses to improve care delivery.

Gene’s dedication to evidenced-based practice and his passion for improving lives for this vulnerable patient population is exemplary. Due to his efforts, patients are receiving preventative treatment that may have lasting positive effects on their overall health and wellbeing.” Those words sum up Shiling’s primary motivation as a nurse at CeDAR.

Why are alcoholics put on thiamine?

Alcohol and Thiamine Deficiency – Normal thiamine uptake by the brain appears to just slightly exceed the amount required for proper brain functioning. Consequently, any reduction in thiamine availability could have serious effects on brain metabolism and may result in brain lesions and cognitive dysfunction.

In alcoholics, several factors may contribute to thiamine deficiency. First, nutritional thiamine deficiency can occur in alcoholics because of their poor eating habits. Alcoholics may eat nothing for days, and when they do eat, their food often is high in carbohydrates and low in vitamins such as thiamine.

In addition, high carbohydrate intake further depletes the already low thiamine levels, because two enzymes involved in the breakdown of carbohydrates (i.e., pyruvate dehydrogenase and alpha-ketoglutarate dehydrogenase) are thiamine-requiring enzymes.

Second, alcoholics may develop a thiamine deficit because of impaired thiamine absorption from the intestine ( Hoyumpa 1980 ). Alcohol damages the lining of the intestine and directly inhibits the transport mechanism that is responsible for thiamine absorption in the intestinal tract ( Gastaldi et al.1989 ).

Also contributing to reduced thiamine uptake may be a nutritional deficiency of the vitamin folic acid, which commonly occurs in alcoholics as a consequence of poor nutrition. Studies in rats found that folic acid-deficient animals absorbed thiamine less efficiently than did healthy rats and that restoration of folic acid intake reversed the thiamine malabsorption ( Howard et al.1974 ).

  1. Third, during chronic alcohol exposure, the activity of thiamine-metabolizing enzymes in the brain is compromised.
  2. To serve as a cofactor for the enzymes involved in energy production and lipid synthesis, thiamine must be converted into an active form by the enzyme thiamine pyrophosphokinase.
  3. Excessive alcohol consumption results in a significant decrease in thiamine pyrophosphokinase activity ( LaForenza et al.1990 ).

In addition, alcohol consumption increases the activity of the enzymes that break down activated thiamine in the brain ( LaForenza et al.1990 ). Through these mechanisms, alcohol could reduce the activity of thiamine-dependent enzymes and affect brain metabolism even in the presence of adequate nutrition and thiamine absorption.

How much thiamine does an alcoholic need?

Abstract – Thiamine deficiency (vitamin B1) is common in patients with alcohol dependence. Cognitive impairments may be an early consequence of thiamine deficiency. Wernicke’s encephalopathy is underdiagnosed and undertreated. In patients with established Wernicke’s encephalopathy, parenteral thiamine 200-500mg three times a day should be given for 3-5 days, followed by oral thiamine 250-1000mg/day.

  • In patients with suspected Wernicke’s encephalopathy, parenteral thiamine 250-300mg should be given two times a day for 3-5 days, followed by oral thiamine 250-300mg/day.
  • In patients at high risk of thiamine deficiency, parenteral thiamine 250-500mg/day should be given for 3-5 days, followed by oral thiamine 250-300mg/day.

In patients at low risk (with uncomplicated alcohol dependence), oral thiamine 250-500mg/day should be given for 3-5 days, followed by oral thiamine 100-250mg/day. Copyright © 2016. Published by Elsevier Masson SAS.

Can I drink alcohol while taking thiamine?

How does thiamine work? Vitamin B1 helps the cells in the body convert food into energy. If you do not have enough vitamin B1 this process cannot work properly. You may have symptoms such as tiredness, loss of appetite and muscle weakness. Taking a thiamine supplement helps restore normal levels of vitamin B1 in your body.

This allows your cells to work properly again and your symptoms should improve. When will I feel better? Taking thiamine will start increasing your body’s levels of vitamin B1 within a few hours. However, if you’re taking it to treat vitamin B1 deficiency, it may take a few weeks before you start to feel better.

It’s important to keep taking your thiamine for as long as the doctor tells you to. Are there any long-term side-effects? There are usually no problems taking thiamine for a long time. Your body absorbs the amount of thiamine (or vitamin B1) that it needs.

peas, lentils and beansyeast or beef extracts (including Marmite and Bovril)eggsoranges and orange juicewheat bran and other wholegrain foodspork, beef and liverfishfortified foods that have thiamine added (including some brands of breakfast cereals, rice, egg noodles and bread)

How will it make me feel? You will not notice much difference in the short term but over a few weeks you should gradually notice your symptoms improving and begin to have more energy again. Thiamine is a very safe medicine and you’re unlikely to get any side effects.

Will it affect my contraception? Thiamine will not stop any type of contraception from working. This includes the combined pill and emergency contraception, However, if thiamine gives you severe diarrhoea for more than 24 hours, your contraceptive pills may not protect you from pregnancy. Look on the pill packet to find out what to do.

Read more about what to do if you’re on the pill and you have diarrhoea, Can I drive or ride a bike? Yes. Thiamine will not affect your ability to drive or ride a bike. Can I drink alcohol while taking thiamine? Long-term drinking or heavy drinking can stop your body from absorbing thiamine (vitamin B1).

If you’re taking thiamine for vitamin B1 deficiency, it’s best to avoid drinking alcohol as this will make your symptoms worse. If you’re taking thiamine as a vitamin supplement, avoid drinking too much. Try to keep to the recommended guidelines of no more than 14 units of alcohol a week. A standard glass of wine (175ml) is 2 units.

A pint of lager or beer is usually 2 to 3 units of alcohol. Is there any food or drink I need to avoid? Apart from avoiding too much alcohol, you can eat and drink normally when taking thiamine. Page last reviewed: 9 February 2023 Next review due: 9 February 2026

Why would a doctor prescribe thiamine?

pronounced as (thye’ a min) Thiamine (vitamin B 1 ) is used as a dietary supplement when the amount of thiamine in the diet is not enough. People most at risk for thiamine deficiency are older adults, those who are dependent on alcohol, or who have HIV/AIDS, diabetes, malabsorption syndrome (problems absorbing food), or have had bariatric surgery (an operation that helps you lose weight by making changes to your digestive system).

Thiamine is used to treat beriberi (tingling and numbness in feet and hands, muscle loss, and poor reflexes caused by a lack of thiamine in the diet) and to treat and prevent Wernicke-Korsakoff syndrome (tingling and numbness in hands and feet, memory loss, confusion caused by a lack of thiamine in the diet).

Thiamine is in a class of medications called vitamins. It is needed by the body to turn foods into energy, which is important for the growth, development, and function of cells. Thiamine comes as a tablet, capsule, and solution (liquid drops) to take by mouth.

  1. It is usually taken once to three times a day depending on the preparation, your age, and your medical condition(s).
  2. Thiamine is available without a prescription, but your doctor may prescribe thiamine to treat certain conditions.
  3. Follow the directions on your product label or doctor’s instructions carefully, and ask your doctor or pharmacist to explain any part you do not understand.

Take thiamine exactly as directed. Do not take more or less of it or take it more often than recommended by your doctor. Thiamine supplements are available alone and in combination with other vitamins. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

How long do alcoholics take thiamine?

Thiamine should be continued for as long as malnutrition is present and/or during periods of continued alcohol consumption. Following successful alcohol withdrawal, thiamine should be continued for 6 weeks.

What vitamin do alcoholics lack?

Abstract – Chronic alcoholic patients are frequently deficient in one or more vitamins. The deficiencies commonly involve folate, vitamin B6, thiamine, and vitamin A. Although inadequate dietary intake is a major cause of the vitamin deficiency, other possible mechanisms may also be involved.

What are the symptoms of low thiamine?

Thiamin deficiency (causing beriberi and other problems) is most common among people whose diet mainly consists of white rice or highly processed carbohydrates in countries with high rates of food insecurity and among people with alcohol use disorder.

A diet consisting mainly of white flour, white sugar, and other highly processed carbohydrates can cause thiamin deficiency. At first, people have vague symptoms such as fatigue and irritability, but a severe deficiency (beriberi) can affect the nerves, muscles, heart, and brain. The diagnosis is based on symptoms and a favorable response to thiamin supplements. Thiamin supplements, usually taken by mouth, can correct the deficiency.

Thiamin deficiency often occurs with other B vitamin deficiencies. Thiamin deficiency may result from

A deficiency of thiamin in the diet

People who consume excessive amounts of alcohol often substitute alcohol for food and thus do not consume enough thiamin, are at high risk of developing this deficiency. Also, alcohol may interfere with the absorption and metabolism of this vitamin and may increase the body’s need for thiamin.

Thiamin deficiency may also result from Early symptoms of thiamin deficiency are vague. They include fatigue, irritability, poor memory, loss of appetite, sleep disturbances, abdominal discomfort, and weight loss. Eventually, a severe thiamin deficiency (beriberi) may develop, characterized by nerve, heart, and brain abnormalities.

Different forms of beriberi cause different symptoms. Nerve and muscle abnormalities develop. Symptoms include a prickling (pins-and-needles) sensation in the toes, a burning sensation in the feet that is particularly severe at night, and leg cramps and pain.

Physical examination Relief of symptoms when thiamin supplements are taken

The diagnosis of thiamin deficiency is based on symptoms and the results of a physical examination, with emphasis on examination of the heart and nervous system. Tests to confirm the diagnosis are not readily available. Blood tests to measure electrolyte levels are usually done to exclude other possible causes.

The diagnosis is confirmed if thiamin supplements relieve symptoms. All forms of thiamin deficiency are treated with thiamin supplements. They are usually given by mouth. They are given intravenously if symptoms are severe. Because thiamin deficiency often occurs with other B vitamin deficiencies, multivitamins are usually given for several weeks.

People are encouraged to eat healthily and are advised to consume 1 to 2 times the daily recommended intake of vitamins Vitamins They should not drink any alcohol. Wernicke-Korsakoff syndrome, a medical emergency, is treated with high doses of thiamin given intravenously or by injection into a muscle (intramuscularly) for several days. Use of alcohol should be stopped. When people who may have a thiamin deficiency, particularly people with alcohol use disorder, must be fed intravenously, they are given thiamin supplements first.

These intravenous solutions contain glucose. Because thiamin is needed to process (metabolize) glucose, glucose may trigger or worsen symptoms of thiamin deficiency. Giving them thiamin supplements first can prevent Wernicke-Korsakoff syndrome from developing or worsening. With treatment, most people recover completely.

In some people with Wernicke-Korsakoff syndrome, some brain damage is permanent. Symptoms of beriberi may recur years after apparent recovery. NOTE: This is the Consumer Version.

Does thiamine help hangover?

Weekend party nights are great but if you had guzzled down a little bit of more alcohol, the next day morning you are regretting it and paying a price! What Is Thiamine For Alcoholics Hangovers are not fun and your body is experiencing various negative effects of alcohol like nausea, vomiting weakness, headache and making you feel worthless. To get over that annoying feeling, you should let your body rest, drink plenty of water, pop in vitamins to replenish your body of the nutrients that were lost after drinking.

Here are few tips to get over hangover symptoms: 1. Sleep Well: Take plenty of rest and try to sleep well. Alcohol unfortunately induces sleep disturbances, so try to be in the bed for at least 10 hours. Switch off the phone, turn off the lights and try avoiding all those factors that might disturb your sleep.2.

Drink water and juices: Alcohol is a diuretic and it makes you dehydrate at a faster pace. Start your day with a glass of water, try drinking fresh vegetable or fruit juices. If you are feeling nausea, nothing helps better than lemon juice. Add a dash of lime, piece of ginger to warm water and drink it down.

  1. This is more effective than any other juices.3.
  2. Eat Something: Hangover makes you nauseate at the sight of the food but eating helps.
  3. Bite into a sandwich, munch on pretzels, a banana or something absorbent.4.
  4. Take a Shower: Go and stand under shower for an instant relief.
  5. This will not only clean you up but freshen your senses, thoughts and make you ready for rest of the day.5.

Get Vitamins: Alcohol drains the body of nutrients and vitamins. Vitamin B- complex pill that include B1 (Thiamine), B2 (Riboflavin), folic acid, B6 and B12 play a major role in the functioning of brain and nervous system and aid your body in getting over the hangover easily.

  • With everyone gearing up for the holiday season, we know most of you are planning for a simple home party or a get-together with your near and dear ones instead of attending a large rave in a disco.
  • But whatever the scenario may be, for most people a Christmas or new year part is never complete without the presence of beverages specifically the ones with alcohol.

As much as you enjoy the party the previous night, one thing is sure you are bound to wake up with a hangover. So, to avoid getting one, try following these simple tips:

What vitamins should I take if I drink a lot of alcohol?

Vitamin Deficiency Treatment In Heavy Drinkers – Vitamin B protects the liver from damage as a result of excess alcohol consumption and can help stabilise mood swings and cognitive function. Evidence suggests that strong Vitamin B compound should be prescribed to alcoholics where:

There is clear evidence of deficiency, poor diet or absorption; or Co-occurring illness likely to increase incidence of deficiency when combined with alcohol intake; or The patient is undergoing withdrawal or detox from alcohol.

Heavy drinkers may benefit from adding vitamin B1, B2, B3, B6, and B9 supplements as indicated by symptoms of deficiencies, and under professional medical guidance. Vitamin B1 deficiency can be treated by ceasing alcohol consumption (with professional help), improving nutritional factors, and taking B1 supplements.

Which foods contain thiamine?

Food – Food sources of thiamin include whole grains, meat, and fish, Breads, cereals, and infant formulas in the United States and many other countries are fortified with thiamin,The most common sources of thiamin in the U.S. diet are cereals and bread,

  1. Pork is another major source of the vitamin.
  2. Dairy products and most fruits contain little thiamin,
  3. About half of the thiamin in the U.S.
  4. Diet comes from foods that naturally contain thiamin; the remainder comes from foods to which thiamin has been added,
  5. Heating foods containing thiamin can reduce their thiamin content.

For example, bread has 20%–30% less thiamin than its raw ingredients, and pasteurization reduces thiamin content (which is very small to begin with) in milk by up to 20%, Because thiamin dissolves in water, a significant amount of the vitamin is lost when cooking water is thrown out,

Processing also alters thiamin levels in foods; for example, unless white rice is enriched with thiamin, it has one tenth the amount of thiamin in unenriched brown rice, Data on the bioavailability of thiamin from food are very limited, Some studies do show, however, that thiamin absorption increases when intakes are low,

Several food sources of thiamin are listed in Table 2.

Can you take too much thiamine?

Toxicity – It is unlikely to reach a toxic level of thiamin from food sources alone. In the setting of very high intakes, the body will absorb less of the nutrient and flush out any excess amount through the urine. There is no established toxic level of thiamin.

Is thiamine hard on liver?

Pantothenic Acid – Pantothenic acid (pan” toe then’ ik as’ id) is a water soluble vitamin (also known as vitamin B5) that is found in many foods including vegetables, eggs, liver and yeast. Pantothenic acid is a component of coenzyme A and is involved in fatty acid and cholesterol metabolism and synthesis of steroid hormones.

Pantothenic acid deficiency has been produced experimentally and causes gastrointestinal disturbance, muscle cramps, paresthesias, ataxia, depression and hypoglycemia. It may be the cause of burning feet syndrome, experienced by prisoners of war. Pantothenic acid deficiency occurs largely as a component of mixed, severe malnutrition with combined vitamin deficiencies.

The recommended dietary allowance of pantothenic acid has not been formally established, but the dietary reference adequate intake is 5 mg daily in adults. Pantothenic acid is available generically in many over-the-counter forms and is included in most multivitamin preparations, typically in concentrations ranging from 1 to 10 mg.

Who Cannot take thiamine?

You should not use thiamine if you have ever had an allergic reaction to it. Ask a doctor or pharmacist if it is safe for you to take this medicine if: you have any other medical conditions; you take other medications or herbal products; or.

How long does it take for thiamine to work?

– Ideally, prevention is the best approach to thiamine deficiency. Eating a diet rich in thiamine-containing foods can help maintain adequate thiamine stores in the body. Again, deficiencies are rare in communities living in highly industrialized countries with consistent access to food.

Additionally, a thiamine-containing supplement, such as a multivitamin or vitamin B complex, will generally provide most of the recommended daily needs for thiamine per serving. Just be sure to check the supplement facts panel to see how much is in yours if you choose to take one.

There is no established upper limit for thiamine. That’s because we don’t have any evidence suggesting that taking it in high doses poses negative health risks ( 25, 26 ). For severe cases of diagnosed thiamine deficiency, high dose supplementation may be used under medical supervision. For example, thiamine supplementation may be given orally, via injections, or using an IV in a clinical setting ( 2, 11 ).

Using this type of clinical thiamine deficiency correction, some heart-related symptoms can be reversed within hours to days ( 2 ). It may take 3 to 6 months to reverse brain and nervous system effects, and people with severe neuropathy due to a delay in diagnosis or treatment may have permanent damage ( 2 ).

Does thiamine make you sleepy?

INTRODUCTION – Excessive sleepers may be at a higher risk for increased morbidity and mortality. Meta-analyses have shown higher overall mortality and disease-specific mortality, such as cardiovascular and cancer-related mortality, among long sleepers.

Cohort studies support the relationship between long sleeping and mortality risk in long sleeping groups even after adjusting for physical and psychological comorbidities, showing that long sleeping is not simply a result of worsened health. Thiamine is an essential co-enzyme of the Krebs cycle. Daily intake of around 0.1 mg/1000 kcal or less causes overt clinical problems such as beriberi,

Current guidelines suggest a minimum intake around 1 mg/day, While thiamine is abundant in crops such as wheat and rice, milling substantially decreases its concentration, Therefore, severe thiamine deficiency is rare and limited to developing countries where milled crops are a cheap source of food,

  1. However, concerns about marginal thiamine deficiency in food-secure environments have been raised,
  2. Individual observational studies have reported proportions of marginal thiamine deficiency from 5.1% in adolescents, to 31% in the hospitalised elderly,
  3. Similarly, in Korea, 38.4% of the adult population reported thiamine consumption lower than the estimated average requirement levels in 2020,

Meanwhile, thiamine deficiency has been suggested to be related to fatigue and sleep disturbances, even at early stages, Animal experiments showed increased sleep duration measured by an electroencephalogram and recovery time after induced narcosis,

  1. Another study showed altered sleeping patterns such as decreased wakefulness,
  2. Experimental studies on populations with marginal thiamine deficiency showed that thiamine supplementation reversed fatigue, while trends for sleep pattern improvement and reduced daytime sleep time were also observed,
  3. However, not much is known about the psychiatric consequences of marginal thiamine deficiency, while real-world epidemiologic evidence is lacking.

The results of previous exploratory studies are limited and inconsistent with regard to the relationship between thiamine intake and excessive sleep, A harmful behaviour that disrupts thiamine metabolism is the overuse of alcohol, Prolonged thiamine deficiency, caused by alcohol overuse, is a known cause of several neuropsychiatric disorders and irreversible brain damage,

Can too much thiamine cause anxiety?

Mood Swings – Vitamin B overdose not only affects one physically but has a negative impact on mental health as well. Some of the negative side effects of vitamin B overdose include mood swings, restlessness, depression, and panic attacks. Mood swings can worsen in people who suffer from paranoia, confusion, or mental fogginess; due to the high doses of vitamin B complex.

How does thiamine help the brain?

Thiamine-dependent processes are diminished in patients with AD – Thiamine status in the blood can be assessed by multiple methods, often indirectly by assaying the activity of the transketolase enzyme, which depends on thiamine pyrophosphate (TPP; also known as thiamine diphosphate), in erythrocyte hemolysates in the presence and absence of added TPP.14 The result, known as the TPP effect, reflects the extent of unsaturation of transketolase with TPP and gives a functional measure of thiamine deficiency.

  • Thiamine and its esters can now also be directly assessed in small samples by very reliable methods.15 Another commonly used measure of thiamine status is urinary thiamine excretion, which provides data on dietary intakes but not tissue stores.
  • For adults, excretion of less than 100 mcg/day thiamine in urine suggests insufficient thiamine intake, and less than 40 mcg/day indicates an extremely low intake.16 In studies that examined thiamine status in patients with AD, the TPP effect on transketolase in blood was significantly higher (12%) in AD than controls, 14 and thiamine in plasma is reduced by about one-third in AD patients.17 These measures suggest that a significant portion of AD patients are thiamine deficient.

Complete measures of all of the thiamine esters have not been made in blood. The activities of thiamine-dependent enzymes in the brain have also been used as a measure of thiamine deficiency. The activity of the three thiamine-dependent enzymes shown in Figure 2 —transketolase, PDHC, and KGDHC—is diminished in AD brains.14, 18 The percent reduction varies (50–100%) between studies, and there are no contravening studies. Role of thiamine in brain glucose metabolism for energy utilization and neurotransmitter synthesis. Like in other tissues, glucose metabolism in the brain uses thiamine-dependent enzymes at critical steps. The brain uses ten times its body mass in glucose compared to the whole body.

  1. Thiamine-dependent enzymes (noted by ***) are situated in key steps of glucose metabolism: transketolase in the pentose shunt, pyruvate dehydrogenase as a link between glycolysis and the tricarboxylic acid (TCA) cycle, and KGDHC in the TCA cycle.
  2. Brain glucose also provides the carbon for synthesis of multiple neurotransmitters, including glutamate and acetylcholine, which are important in AD.

The cognitive enhancers used in AD target the neurotransmitters acetylcholine and glutamate. Normal metabolism also results in production of reactive oxygen species (ROS), which contribute to tissue damage, including neuropathy in diabetes.

Does thiamine cause weight gain?

3.1. Thiamine Increased Adipose Lipolysis during NEB but Did Not Affect Body Weight – The effect of high-dose thiamine treatment in mature ewes was investigated under two nutritional states, i.e., PEB and NEB using three treatment groups CG, T5, and T10 ( Figure 1 ). Weight gain response under positive (PEB) and negative (NEB) energy balance states in the control and thiamine treated groups. Effect of Treatment ( p = 0.83), nutritional state ( p < 0.0001), time ( p < 0.0001), and Treatment by Nutritional State interaction ( p = 0.94). CG: Control, T5: Thiamine treatment at 5 mg/kg, T10: Thiamine treatment at 10 mg/kg. Weight response under positive (PEB) and negative (NEB) energy balance states in the control and thiamine treated groups. Effect of Treatment ( p = 0.67), Nutritional State ( p < 0.0001), time ( p < 0.0001), and Treatment by Nutritional State interaction ( p = 0.33). CG: Control, T5: Thiamine treatment at 5 mg/kg, T10: Thiamine treatment at 10 mg/kg.

Is 500mg of B1 too much?

Are There Any Risks Associated With Too Much Vitamin B1? – Thiamin is generally considered safe and nontoxic, even at high doses. Doses higher than 100 mg may cause drowsiness or muscle relaxation, and some people report a burning sensation when thiamin is received via injection.

Navbar Search Filter Mobile Enter search term Search Aims An important mechanism in alcohol-induced injury is biomolecular oxidative damage. Folic acid is supplied to chronic alcoholic patients in order to prevent this situation, as this is the main vitamin deficiency that they suffer from.

Acute alcohol exposure, such as binge drinking, is one of the most widespread ethanol consumption models practiced by adolescents. However, there is no evidence of folic acid body profiles after this pattern of consumption. Methods Four groups of adolescent rats were used: control, alcohol (exposed to intraperitoneal binge drinking), control folic acid-supplemented group and alcohol folic acid-supplemented group.

Folic acid levels, protein, lipid and DNA oxidative damage in serum, and liver glutathione (GSH) and reduced/oxidized glutathione ratio (GSH/GSSG) were measured. Results Binge-drinking rats had higher lipids and DNA oxidation levels. They also had lower hepatic GSH levels and GSH/GSSG ratio.

  1. Folic acid supplementation to binge-drinking rats does not change the serum protein oxidation but decreases lipid and DNA oxidation.
  2. Finally, GSH increased to control levels with folic acid supplementation.
  3. Conclusion Folic acid supplementation is an economic and efficient therapy against the oxidative damage in lipids and mainly in DNA stability caused by binge drinking during adolescence.

It has also been demonstrated that folic acid increases GSH levels, improving the antioxidant status and revealing a hepatoprotective effect during binge drinking.

Why is thiamine given before glucose in alcoholics?

Identification and management of acute alcohol intoxication In particular, it is advisable to administer thiamine before any glucose load, due to the risk of accelerating the onset of Wernicke’s encephalopathy.

Does thiamine help the liver?

This discovery of the potent anti-steatotic effect of thiamine may prove clinically useful in managing fatty liver-related disorders.

How does thiamine work?

Function. Thiamin (vitamin B1) helps the body’s cells change carbohydrates into energy. The main role of carbohydrates is to provide energy for the body, especially the brain and nervous system. Thiamin also plays a role in muscle contraction and conduction of nerve signals.

What is the mechanism of action of thiamine?

Mechanism of Action – Thiamin is a water-soluble vitamin and is absorbed into the blood from the gastrointestinal tract. It then circulates in the blood and ultimately gets excreted in the urine. Small amounts of thiamin are stored in the liver, heart, kidney, and brain, but only for a short duration.

  1. TPP works with enzyme functions during the metabolism of carbohydrates, lipids, and branched-chain amino acids.
  2. TPP acts as a cofactor at several steps during glycolysis and oxidative decarboxylation of carbohydrates.
  3. TPP acts as a coenzyme for the mitochondrial enzyme complexes such as α-ketoglutarate dehydrogenase and pyruvate dehydrogenase. These enzymes have a critical role in the Krebs cycle and tricarboxylic acid cycle. Thiamin deficiency decreases the activity of these enzymes, which impairs the conversion of lactate into pyruvate, leading to the accumulation of lactic acid. Lactic acidosis may cause focal damage to certain brain structures, such as mamillary bodies and the posteromedial thalamus, which can be seen on MRI.

The presence of TPP is required by the erythrocyte transketolase enzyme during the pentose phosphate pathway of nucleotide synthesis and provides reduced nicotinamide adenine dinucleotide phosphate for several synthetic pathways.
