Vitamin B1 (Thiamine)
What Is Vitamin B1 (Thiamine)?
Vitamin B1, also called thiamine, is a water-soluble vitamin — meaning it dissolves in water and is not stored in large amounts, so the body needs a steady supply from food or supplements. It is found in whole grains, legumes, nuts and pork. Its main job is helping the body turn the carbohydrates you eat into energy, and it keeps nerves and the heart working normally.
A shortage of thiamine causes a condition called beriberi (affecting the nerves and heart) and, with heavy alcohol use, Wernicke's syndrome (affecting the brain). Most benefits of supplementing come from preventing or correcting a shortfall.

Vitamin B1 Benefits: What Is Thiamine Good For?
| Benefit | What the human evidence shows |
|---|---|
| Supports energy metabolism | Thiamine is an essential helper for the enzymes that release energy from carbohydrates — a well-established role; a shortfall leaves cells short of fuel. |
| Supports nerve function | Correcting thiamine shortfall relieves the nerve symptoms of beriberi; thiamine is essential for healthy nerve signalling. |
| May support heart function | In a small crossover trial, thiamine 300 mg/day improved heart pumping (ejection fraction) in people with heart failure. Schoenenberger A et al., Clin Res Cardiol, 2012 — RCT, small pilot; a meta-analysis of thiamine trials found a similar signal. DiNicolantonio J et al., 2013 — meta-analysis. |
| May support blood-sugar handling | High-dose thiamine 300 mg/day improved glucose tolerance in a crossover trial of people with early high blood sugar. Alaei Shahmiri F et al., Eur J Nutr, 2013 — RCT. |
Honest note: thiamine's clearest value is preventing and correcting a shortfall. The heart and blood-sugar trials are small and preliminary, so treat those as early signals, not proven treatments. Thiamine shortfall is more common in people with diabetes and heavy alcohol use (Thornalley P, 2007).
How Does Vitamin B1 Work?
- Unlocks energy from carbs. Thiamine becomes a molecule (thiamine pyrophosphate) that key energy enzymes need to break down glucose for fuel.
- Keeps nerves firing. It supports the chemistry nerves use to send signals, which is why a shortfall shows up first as nerve and muscle symptoms.
- Supports the heart muscle. Because the heart is energy-hungry, low thiamine can strain it — correcting a shortfall helps.
Vitamin B1 Uses: Energy, Nerves & Heart Health
| Concern | How thiamine may help & how strong the evidence is |
|---|---|
| Low energy / tiredness from shortfall | Restores energy metabolism when intake is low. Well established for deficiency. |
| Nerve health | Essential for nerve signalling; corrects deficiency symptoms. Well established for deficiency. |
| Heart failure support | May improve heart pumping. Limited — small trials only. |
| Blood-sugar handling | May improve glucose tolerance at high doses. Preliminary — treat as an early signal. |
Vitamin B1 Dosage: How Much & When
Dose. Everyday needs are small (around 1–1.5 mg/day). Supplements and B-complex products often provide more because thiamine is water-soluble and any excess is passed in urine. Follow your product label.
Timing. Can be taken with or without food, at any time of day.
Vitamin B1 Side Effects & Who Should Avoid It
- Very well tolerated — Thiamine is water-soluble and considered safe; extra amounts are simply passed out in urine. No upper limit has been set because side effects are rare.
- A supplement, not a treatment — Vitamin B1 supports energy, nerve and heart health but does not replace medical care for any condition. WellBeingMora Vitamin B1 is a daily wellness supplement.

Frequently Asked Questions
What is vitamin B1 (thiamine) and what is it used for?
Vitamin B1, or thiamine, is a water-soluble B vitamin that helps turn the carbohydrates you eat into energy and keeps nerves and the heart working normally. It is used mainly to support energy and to prevent or correct a thiamine shortfall.
What are the benefits of vitamin B1?
Its clearest benefits are supporting energy metabolism and nerve function, and correcting deficiency. Small trials also suggest possible support for heart pumping and blood-sugar handling, though those are preliminary.
What are the symptoms of vitamin B1 deficiency?
A shortfall can cause tiredness, nerve tingling, poor appetite and, when severe, beriberi (affecting nerves and heart). It is more common with heavy alcohol use and in people with diabetes.
What foods are high in vitamin B1?
Whole grains, legumes, nuts, seeds and pork are good sources. Refined and polished grains lose much of their thiamine.
What is the right vitamin B1 dosage?
Everyday needs are small (about 1–1.5 mg/day). B-complex and multivitamin products often provide more, which is safe because excess thiamine is passed in urine. Follow your product label.
When should I take vitamin B1?
It can be taken at any time, with or without food.
Are there side effects of vitamin B1?
Thiamine is very well tolerated. Because it is water-soluble, extra amounts are simply passed out in urine, and side effects are rare.
Does vitamin B1 give you energy?
It helps your body release energy from carbohydrates. If your levels are already adequate, extra thiamine will not act like a stimulant, but correcting a shortfall can relieve tiredness.
Can I take vitamin B1 with other B vitamins?
Yes. The B vitamins work together, which is why WellBeingMora includes B1 with all eight B vitamins in Active B-Complex Plus.
Is WellBeingMora vitamin B1 vegetarian and allergen-free?
Yes. It is suitable for vegetarians and formulated without yeast, milk, lactose, soy, wheat, eggs, peanuts, shellfish, dairy, artificial flavours, or artificial sweeteners.
Final Thoughts
Vitamin B1 (thiamine) is an essential vitamin whose everyday value is steady energy metabolism and nerve health. Its strongest, most certain benefit is preventing and correcting a shortfall; the heart and blood-sugar trials are small and early, which we would rather state plainly than overstate.
It is very safe, water-soluble, and works best as part of the full B-vitamin team. WellBeingMora includes it in Active B-Complex Plus and the Whole Food Multivitamin — FSSAI registered, made in a GMP & US FDA registered facility, tested for purity, and free from common allergens. It is a wellness supplement, not a treatment for any condition.
