B Complex refers to a group of eight essential vitamins that play a vital role in maintaining overall health. These vitamins include B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (cobalamin). They are important for energy production, brain function, and the formation of red blood cells. Each vitamin in the B Complex has unique functions. For example, B6 is crucial for protein metabolism, while B12 is essential for nerve health. These vitamins are commonly found in foods like whole grains, meat, eggs, and leafy greens, making a balanced diet important for obtaining adequate amounts.
