Product Description

Doctor's Best Fully Active B Complex contains all eight important B Vitamins, a fully 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.
