Benefits
Promotes skin elasticity, joint health, and hair strength due to its high collagen content.
L-arginineGood
L-arginine is an amino acid that plays a role in protein synthesis and vasodilation. It is known to improve blood flow and may support cardiovascular health. This ingredient can enhance nutrient delivery to hair follicles, potentially promoting hair growth.
