Synopsis

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

Flavanols, a subgroup of flavonoids found in foods like cocoa, tea, apples, and berries, have been studied for their potential benefits on eye health, particularly due to their antioxidant and vascular effects. The scientific rationale centers on their ability to neutralize free radicals, reduce oxidative stress, and enhance blood flow—factors relevant to common eye problems such as age-related macular degeneration (AMD) and diabetic retinopathy. Some preclinical studies suggest flavanols may protect retinal cells against oxidative damage. A few human studies, such as those examining the effects of cocoa flavanols, have shown improved retinal blood flow and visual function in healthy individuals or those with glaucoma. However, large-scale clinical trials directly linking flavanol supplementation to prevention or treatment of major eye diseases are lacking, and current evidence is mostly preliminary or indirect. The European Food Safety Authority (EFSA) and similar authorities have not approved health claims for flavanols specifically for eye health. Thus, while there is a plausible scientific basis and some early supportive data, the overall evidence is limited and not yet robust enough for strong recommendations.
