Chicken collagen is used to treat joint pain associated with many types of arthritis and surgery, as well as back pain, neck pain, and pain following injury.
Insufficient Evidence to Rate Effectiveness for...
- Osteoarthritis. Early research shows that taking a specific product (AR7 Joint Complex by Robinson Pharma) containing collagen type II, methylsulfonylmethane (MSM), cetyl myristoleate, lipase, vitamin C, turmeric, and bromelain by mouth for 12 weeks reduces joint pain and tenderness in people with osteoarthritis. However, it does not seem to improve X-rays of affected joints.
- Rheumatoid arthritis (RA). Research on the effects of collagen type II in people with RA shows conflicting results. Some research shows that taking collagen type II by mouth for 3 months reduces joint pain, swelling, and time to walk 15 meters in people with RA. However, other research does not show these improvements when collagen type II is taken for longer periods of time or in higher doses. Also, other research suggests that collagen type II is less effective than the drug methotrexate for treating RA.
