Why do people take gelatin?
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 pain in 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.
There's no standard dose for gelatin. Ask your health care provider for advice.
