What was studied?

Richmond and colleagues (2013) enrolled 70 people with painful rheumatoid arthritis in a randomized crossover trial. Participants wore four devices, including a copper bracelet and different magnetic wrist straps, in varying orders for five weeks each, with washout periods.

What did the trial find?

The researchers found no statistically significant differences between devices for the measured outcomes, including pain, inflammation and physical function. They concluded that a copper bracelet did not appear to provide meaningful therapeutic benefit beyond placebo in this setting.

What should not travel with the result?

This trial concerns these devices, participants and outcomes. It is not a test of every copper product or a proof that any material has no value. Our editorial conclusion: do not market a copper bracelet here as a treatment for rheumatoid arthritis.

Educational study summary, not medical advice. Do not replace or change prescribed care based on a product story.
