In nature, lutein and zeaxanthin seem to absorb excess light energy to prevent damage to plants through too much sunlight, especially from high-energy light rays called blue light.

Inside fact, the macula also is called the particular “macula lutea” (from the Latin macula, meaning “spot, ” plus lutea, meaning “yellow”).

Recent research has discovered a third carotenoid within the macula. Called meso-zeaxanthin, this pigment is not found in food sources and appears to be created in the particular retina from ingested lutein.

Lutein plus zeaxanthin appear to have important antioxidant functions in the body. Along with other natural antioxidants, including vitamin D, beta-carotene and vitamin E, these important pigments guard the body through damaging effects of free radicals, which are unstable molecules that can destroy cells and play a role in many diseases.

In addition to important eye and vision benefits, lutein may help protect against atherosclerosis (buildup of fatty deposits in arteries), the disease that leads to most heart attacks.

 

Selenium
