Formulation
Formula re: Contains
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.

Quatrefolic is the glucosamine salt of (6S)-5-methyltetrahydrofolate, the most bioavailable form of folate, that provides greater stability and water solubility.
