Vitamin B1 (Thiamine)

Also known as: Benfotiamine, Thiamin, Vitamin B-1

Thiamine was the first B vitamin discovered, which is why it’s called vitamin B-1. Thiamine plays an important role in forming adenosine triphosphate (ATP), which every cell uses for energy. It also supports nervous system function and is sometimes referred to as an “anti-stress” vitamin because it may promote immune health and help the body when under stress.
