Many people with arthritis take gelatin supplements. Gelatin contains collagen. That's a material in the cartilage that cushions the bones in your joints.
The idea behind this usage is that eating gelatin (with collagen) will add collagen to your joints. However, that's probably not true. The collagen in gelatin gets broken down when you eat it. It wouldn't travel directly to your joints.
Nonetheless, there is some evidence that gelatin could help ease joint painin people with osteoarthritis.
In animal studies, gelatin supplements also reduced swelling caused by rheumatoid arthritis. However, we need more research to know if gelatin is effective in either of these cases.
