vitamin B complex
Eight essential nutrients
A group of water-soluble vitamins that work together in cell metabolism and energy production.
The complex includes thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folate (B9), and cobalamin (B12).
Despite the numbering gaps—some compounds originally classified as B vitamins were later found not to be—these eight are recognized as essential nutrients: My doctor recommended a B complex supplement.
