Vitamin B1 (Thiamine) is an essential B vitamin that serves as a cofactor for enzymes involved in energy metabolism and carbohydrate utilization, which supports cognitive function, nerve health, and cellular energy production throughout the body.
How to Take Vitamin B1
Vitamin B1 is typically dosed at 50-100 mg daily for cognitive support (well above the RDA of 1.2 mg), can be taken once daily with or without food, and fat-soluble forms like benfotiamine or sulbutiamine have better bioavailability and blood-brain barrier penetration than standard thiamine.
