Synopsis

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

Proanthocyanidins are a class of polyphenols found in various plants, including grapes, berries, and pine bark. Their use for supporting eye health is primarily based on their antioxidant properties, which may help protect ocular tissues from oxidative stress. Several laboratory and animal studies suggest that proanthocyanidins can protect retinal cells from oxidative damage and may improve microcirculation in the retina, potentially benefiting eye health. Some small clinical studies have evaluated extracts rich in proanthocyanidins, such as grape seed extract or Pycnogenol (French maritime pine bark extract), for their effect on eye health, particularly in conditions like diabetic retinopathy or improving visual function in healthy individuals. However, these studies are generally small, sometimes lack rigorous controls, and results are not always consistent.

Currently, there is insufficient large-scale, high-quality clinical evidence to robustly support the use of proanthocyanidins specifically for eye health in humans. While their antioxidant capabilities are well-established, their direct impact on preventing or treating eye diseases remains under investigation. Therefore, the evidence for supporting the eyes with proanthocyanidins is scientific in nature but limited, warranting a moderate evidence rating.
