GNLD's Super-B supplement contains all 10 B vitamins with a sustained release technology to ensure 6 hours of bioavailability. It provides the complete B vitamin family from a whole food source of biologically bound yeast. The B vitamins are important for energy production, heart health, birth defects prevention, immune function, and mental well-being but are not stored in the body and can be depleted by stress, medications, and poor diet. Super-B's sustained release helps maximize B vitamin absorption and utilization for increased energy, cell growth, and overall health support.
