Although the exact cause of age-related macular degeneration or ARMD, as it is often referred to, is not totally clear, it is believed that free radical damage plays a role, as it does in other age-related diseases. The fats become hard and adhere to the arterial walls, like plaque on your teeth.

In so doing, they reduce the risk of age-related diseases caused by oxidation. Antioxidants of all kinds help to prevent oxidative damage from free radicals by neutralizing them. Free radicals cause oxidation of fats within the arteries. Several studies have now been published and researchers are even learning how to measure the density of the retinal pigmentation, before and after supplementation. They have seen that supplementation does, in fact, increase the density of the pigmentation within the retina and that, they believe, prevents further damage, reducing the risk of blindness. Blood pressure goes up and heart disease begins.

The walls become irritated, inflamed and less flexible.
