Twenty-two patients with glaucoma were enrolled and randomly assigned to a food supplement or control treatment group while their intraocular pressure was being treated by topical drugs. The food supplement treatment consisted of 2 tablets per day (1 in the morning, 1 in the evening) given for 1 year of homotaurine, Coleus forskohlii root extract, L-carnosine, folic acid, vitamins B1, B2, B6, and magnesium. Patients who took the supplements had a significant further decrease in eye pressure.
Comments: I am not sure which of the individual supplements had more of an effect than the others. Homotaurine is related to the amino acid taurine and I don't think it is available as a supplement. Coleus forskohlii extract has been studied as a natural way to reduce eye pressure. Carnosine is an interesting substance with many health benefits.
