What are proanthocyanidins? Proanthocyanidins or condensed tannins, also calledpycno-genols and leukocyanidins, are polyphenolic compounds (in particular they are a flavonoid subgroup) widely distributed in the plant kingdom, second only to lignin as the most abundant phenol in nature.
Doses of proanthocyanidins at two hundred mg per day for a period of five weeks significantly improved various aspects of vision in otherwise healthy and normal people, measured as improved visual performance in the dark as well as visual acuity after exposure of the eye to a glare.
