B-Complex 用于 Slow Metabolism

C

B vitamins are essential coenzymes in all energy metabolism pathways. B12 deficiency is associated with 2.3x higher obesity risk. Supplementation improves metabolic parameters in deficient obese individuals. Benefits are primarily indirect through correcting deficiency states.
