It helps to hold lubricating moisture in joints and cartilage, which affects their resilience, elasticity, and strength. Source Naturals Hyaluronic Acid is made from patented BioCell Collagen®, which has undergone a hydrolysis process that yields low molecular weight hyaluronic acid, chondroitin sulfate, and collagen type II peptides. These elements make it a multifaceted ingredient, which may help support joint function and the appearance of healthy skin.
