Bilberry and tumeric are both powerful antioxidants. I believe curcumin, the active ingredient in tumeric is being tested in a clinical trial now. I take tumeric after I asked my retinal specialist about it. He said it wouldn’t hurt me to try it. I don’t know if any clinical trials are being done with bilberry. It’s always good to discuss supplements with your doctor. Some supplements can interact with medications you may be taking. Warmly, Sharon Moore patient leader
