Supports Skin Health: Collagen peptide supplements may help slow skin aging by reducing wrinkles and dryness. The wrinkle-reducing effects of collagen supplements have been attributed to their ability to stimulate the body to produce collagen on its own. Additionally, taking collagen supplements may promote the production of other proteins that help structure the skin, including elastin and fibrillin. Supports Joint Health. Taking collagen supplements may help improve symptoms of osteoarthritis and reduce joint pain overall. Early research may support supplemental collagen may accumulate in cartilage and stimulate tissues to make collagen. This may lead to lower inflammation, better support of the joints and reduced pain. Supports Lean Body Mass. Studies suggest that collagen supplements could help boost muscle mass in people with sarcopenia, (the loss of muscle mass that happens with age). Researchers have suggested that taking collagen may promote the synthesis of muscle proteins such as creatine, and may also stimulate muscle growth after exercise.
