Good news on the research front, see this link:
Researchers in Saudi Arabia looked at the ability of L-carnitine to protect the eyes from oxidative damage. They concluded “ L-carnitine is capable of protecting the retinal pigment epithelium cells from H2O2-induced oxidative damage, implying that micronutrients can have a positive effect and can play an important role in the treatment of oxidation-induced ocular disorders." Further studies are needed to understand the mechanism of LC-induced protection to the RPE cells.
If you like the idea of Carnitine supplementation, we offer two Geronova Research products, a Carnitine Liquid and Carnitine Plus. Both are high quality sources of carnitine.
