Vitamin B Complex

Vitamin B-complex is a dietary supplement containing a combination of essential water-soluble B vitamins, typically including B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folic acid), and B12 (cobalamin). These vitamins play critical roles in cellular functioning, red blood cell production, and support of the nervous system.

Dosage by Body Weight

Adults typically take 1 tablet or capsule daily, or as directed by a healthcare professional, preferably with a meal to enhance absorption and reduce stomach upset. For children, dosage is based on age, diet, and clinical need using pediatric-specific formulations.
