HealthyHey Nutrition Vitamin B1 1100mcg Vegetable Capsuleis made using thiamine, an essential nutrient that all tissues of the body need to function properly. Thiamine was the first B vitamin that scientists discovered. This is why its name carries the number. Like the other B vitamins, thiamine is water-soluble and helps the body turn food into energy. The body needs thiamine to make adenosine triphosphate (ATP). This is a molecule that transports energy within cells.
