Glucosamine, a natural compound found throughout the body, has been used to treat osteoarthritis for years. Research now suggests that it might have a wider use for other disorders.

It is an important molecule for maintaining cell structure — especially of cartilage and connective tissues. It is also a powerful anti-inflammatory.

Several studies have shown glucosamine protects the eyes and reduces inflammation and damage within the retina.

This would make it especially useful for treating and preventing glaucoma, uveitis, conjunctivitis, and an assortment of inflammatory retinal diseases.

Glucosamine was shown to reduce inflammatory cytokine levels in the retina, on the surface of the eye, and in several internal eye structures. It also acted as an antioxidant.

Studies of the retina have shown that glucosamine could significantly reduce the level of inflammatory cytokines and adhesion molecules.

Both play a major role in retinal diseases such as glaucoma, retinitis pigmentosa, and macular degeneration — especially more destructive wet form.

The compound has also been shown to significantly promote wound healing and regeneration of skin integrity, in part by stimulating the production of hyaluronic acid, a major component of connective tissue that gives skin it youthful firmness.

In addition, glucosamine improved skin hydration and reduced wrinkles.

Glucosamine has also been found useful for treating inflammatory bowel diseases, cardiovascular disease, neurological disorders, migraine headaches, and even some forms of cancer.
