Landish marine collagen products are Health Canada approved for reducing joint pain (NPN: 80108792 and NPN: 80117128).
Collagen hydrolysate has been shown to help with osteoarthritis by having a protective effect on cartilage and by improving cartilage regeneration (1)(2). Collagen synthesis is severely diminished in patients with osteoarthritis, while it is understood that the consumption of glycine (found in high concentration in Landish marine collagen) is associated with enhanced collagen production (2).
Research shows that the consumption of hydrolyzed collagen can help to alleviate joint pain (3). In one study (4), daily consumption of collagen helped to reduce joint pain in patients with arthritis of the knee or hip. Collagen consumption has also been shown to benefit athletes who experience joint pain. A clinical study of 97 athletes showed an improvement in joint pain after consuming collagen for 24 weeks (4).
Although research is limited on the exact impact that collagen has on ligaments and tendons, all connective tissue is primarily made of collagen. Therefore, supplementing with collagen could help to maintain the health and integrity of connective tissue, especially with age since the body's production of collagen begins to decline at approximately age 20 (5).
