What other effects does collagen have?
Sources:
Collagen has several effects beyond improving skin appearance. Its benefits extend to various parts of the body due to its rich composition of amino acids like glycine, proline, and hydroxyproline.
-
Joint and Bone Health: Collagen helps support joint health by providing necessary components for cartilage repair. It may contribute to increased bone density, as indicated by studies showing improvements in bone strength and structure when collagen supplements are used over extended periods 1.
-
Gut Health: There is some evidence that collagen can support gut health by maintaining the integrity of the gut lining. This is due to the same structural proteins aiding in tissue repair elsewhere in the body 2.
-
Hydration and Skin Plumping: Collagen increases blood osmolality slightly, leading to more water retention in the blood vessels. This could make the skin appear more hydrated and plump, though it may also raise blood pressure in some individuals 3.
-
Tendon and Ligament Support: Although it doesn't directly build muscle mass due to a lack of essential amino acids, collagen might still contribute to the health of tendons and ligaments by supplying specific amino acids needed for their structure, although this is harder to quantify 4.
-
Anti-Inflammatory Benefits: Some dermatologists and researchers suspect collagen might offer anti-inflammatory effects, potentially reducing joint pain and promoting faster recovery from injuries, though the exact mechanisms are not fully understood 5.
In summary, while collagen is often used for cosmetic purposes, its potential benefits also encompass joint, bone, gut health, and more, making it a valuable supplement for overall wellness.
