Vitamin B1 (Thiamine)

Vitamin B1, or thiamine, helps the body turn carbohydrates into energy and supports healthy nerve, muscle and heart function. The body stores only a small amount, so thiamine must come from the diet every day. Pork, whole grains, legumes and seeds are good sources.

This collection includes thiamine HCl, benfotiamine (a fat-soluble form of B1), lipothiamine and B1 combined with B6, from brands such as Xymogen, Life Extension, Ecological Formulas, NutriDyn and NOW.

How to Choose a Vitamin B1 Supplement

• Thiamine HCl: The standard water-soluble form. B-1 100 mg by NOW and All Thiamine by Ecological Formulas are simple options.
• Benfotiamine: A fat-soluble form of B1 that reaches higher levels in the body. Popular for nerve health and healthy blood sugar metabolism.
• Lipothiamine: Another fat-soluble form of thiamine by Ecological Formulas.
• Combinations: Adrenal B1B6 by NutriDyn, our top seller, pairs thiamine with B6 for stress and energy support. Benfotiamine with Thiamine by Life Extension combines both forms.
• Dose: Products range from 50 mg to 250 mg per capsule.

Coffee, tea and alcohol can lower thiamine levels, so people who drink a lot of them may need more B1. Thiamine is also in every B complex. See also glucose support and energy supplements.
