Lutein is unstable to light and hydrogen, and it has to be stored in sealed, cool, dark and dry condition.

Lutein has a lot of health benefits. It has antioxidant property, and it may scavenge free radicals, support eye health, protect skin from ultraviolet ray damage, reduce the risk of suffering diabetes, and inhibit the increase of cancer cells.

Lutein is primarily used as a colorant in food and supplements due to its yellow-red color. It appears yellow at low concentrations and orange-red at high concentrations.
