Description
"Vitamin B Complex" is a group of eight water-soluble vitamins, including thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folic acid (B9), and cobalamin (B12). Each participates in metabolism, nerve function, and red blood cell formation. Collectively, they help convert food into energy, support brain activity, and maintain cardiovascular function. Ensuring an adequate intake of these vitamins contributes to proper physiological balance and sustained well-being.

Deficiency Symptoms
A deficiency in the vitamin B complex can result in symptoms such as fatigue, anemia, poor concentration, nerve pain, muscle weakness, cracked lips, and skin rashes. Severe deficiencies may lead to beriberi, pellagra, or megaloblastic anemia, depending on which B vitamin is lacking.
Synergists & Antagonists
Vitamin B-complex works synergistically to support energy metabolism, brain function, and nervous system regulation. Specifically, vitamins B6, B9, and B12 help regulate homocysteine levels, promoting cardiovascular health. No significant antagonistic interactions exist when taken in appropriate amounts.
