Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Proanthocyanidins, a class of polyphenolic compounds found in foods such as grapes, berries, and cocoa, are known for their potent antioxidant properties. Their use to support eye health is primarily based on their ability to combat oxidative stress, which plays a significant role in the development of age-related eye disorders such as cataracts and macular degeneration. Some scientific studies, including small clinical trials and animal studies, suggest that proanthocyanidins may protect retinal cells and capillaries, contributing to the maintenance of visual function. For example, grape seed extract, which is rich in proanthocyanidins, has demonstrated protective effects against oxidative damage in ocular tissues in preclinical models. However, robust, large-scale human clinical trials directly linking proanthocyanidin supplementation to improved eye health or prevention of eye disease are limited. As such, while there is some scientific rationale and early evidence supporting their use for eye health, the overall quality and quantity of evidence remain moderate at best, justifying a middling rating. More rigorous clinical research is needed to definitively establish efficacy.
