Citicoline (Cognizin®) 500 mg and Niacin 54 mg. Glaucoma is a chronic degenerative disease caused by factors independent of intraocular pressure and characterized by progressive visual field loss. Appropriate dietary supplementation combined with hypotensive medical therapy (to reduce intraocular pressure) can support glaucoma patients. Gangliofid, thanks to the combination of nutrients such as citicoline and niacin, can help improve the neuronal function of the optic structures and preserve visual function in glaucoma patients. One tablet per day can be chewed or dissolved in the mouth; no water is required.
