Product Overview


  • Vitamin Supplement
  • Supports Energy Production

Vitamin B-1 (thiamin) is essential for the metabolism of carbohydrates, some amino acids and alcohol. It is also necessary for the production of the neurotransmitter acetylcholine, and for the detoxification of both alcohol and lactic acid (a by-product of strenuous exercise). Thiamin has important roles in the production of energy and ATP derived from reactions in the Krebs cycle. A high carbohydrate diet, strenuous physical exercise, or chronic alcohol consumption may increase the physiological need for vitamin B-1.

Suggested Use

1 tablet daily.

Other Ingredients

Dibasic calcium phosphate, stearic acid, modified cellulose gum, and silica.

contains calcium

Posted by FightingFatigue on September 2 2016 | Verified Purchase

These are cheap but they contain calcium. I'm trying to up my magnesium and this means I need to take even more magnesium to counter the calcium so I will have to chuck them out

Thanks for your feedback!
