Vitamin B complex refers to a group of eight essential vitamins that play crucial roles in various bodily functions, including metabolism, energy production, and cell health. These vitamins are water-soluble, meaning the body does not store them in large amounts, and excess amounts are typically excreted in urine. The eight B vitamins that make up the vitamin B complex are thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folate (B9), and cobalamin (B12).
