Vitamin B1 in our Vitamin B Complex

The B vitamins are a group of water-soluble vitamins that work closely together and therefore depend on one another both directly and indirectly. As a result, the B vitamins can be considered their own closely knit complex. Our B complexes supply the active coenzyme forms of individual B vitamins, which we obtain from plant-based sources or nature-identical active ingredients.
