Does Longevinex resveratrol really help for age-related macular degeneration?

Reviewed and edited by Tod Cooperman, M.D. cooperman.png

Answer:

As discussed in the Resveratrol Supplements Review, there have been several reported cases, all from the same doctor, of people with age-related macular degeneration (AMD) experiencing improvement or slowed progression of the disease while taking Longevinex. A laboratory study also suggests that resveratrol itself can inhibit the production of growth factors, the overexpression of which is known to worsen AMD in human retinal cells. However, there do not appear to be any randomized, placebo-controlled studies on the effects of Longevinex in people with AMD, as would be needed to determine its efficacy for AMD. More about this, plus evidence for other uses of resveratrol and our tests of popular products, is found in the Resveratrol Supplements Review >>

Is there any evidence that some supplements can help normal-tension glaucoma? It is often due to vascular dysregulation, but are treatments for that helpful?

Hi Helen - Some studies have found that in people with normal tension glaucoma, ginkgo biloba extract increased blood flow to certain parts of the eye (http://www.ncbi.nlm.nih.gov/pubmed/21976939) and improved pre-existing visual field damage, without changes in eye pressure (http://www.ncbi.nlm.nih.gov/pubmed/12578781). However, not all studies have found a benefit.

See the "What to Consider When Using" section of the Ginkgo Biloba Supplements Review ( https://www.consumerlab.com/reviews/ginkgo-supplements-memory-review/ginkgobiloba/#tips) for more information.
