B-Complex (Energy Focus)
Essential coenzymes that drive every step of cellular energy metabolism.
Also known as: B Vitamins • Vitamin B Complex • B-50/B-100
Overview
B vitamins are a group of eight water-soluble vitamins that serve as essential coenzymes in energy metabolism. They are required for converting carbohydrates, fats, and proteins into ATP. B1 (thiamine), B2 (riboflavin), B3 (niacin), and B5 (pantothenic acid) are directly involved in the Krebs cycle and electron transport chain. B6, B9 (folate), and B12 support methylation and red blood cell formation.
