Doctor’s Best Fully Active B Complex contains all eight important B Vitamins, a full spectrum designed for optimal absorption and utilization to support overall health and well-being. Water-soluble B vitamins play important roles in cell metabolism, supporting DNA, organs, genes, cells, tissues, skin health, immune system, enzyme functions and energy production. Quatrefolic is the glucosamine salt of (6S)-5 methyltetrahydrofolate,the most bioavailable form of folate, that provides greater stability and water solubility. Folate is an essential vitamin to support DNA, proper cell division, heart, mental and emotional well-being.

Biotin is a water-soluble vitamin necessary for normal growth and body function. Biotin functions as a key regulatory element in gluconeogenesis, fatty acid synthesis, and in the metabolism of some amino acids. Alongside its role in energy production, Biotin enhances the synthesis of certain proteins. In addition, Biotin promotes healthy immune system function and plays a critical role in skin health.
