The Most Purified Form of Lutein (Marigold Extract) Is Finally Here... Kosher-certified Pesticide-free Granted GRAS status Manufactured by Biolut™ S.A. de C.V. Distributed Exclusively by Blue California Lutein is a naturally occurring molecule found in dark green leafy vegetables such as spinach, kale and collard greens and numerous studies have suggested that lutein intake fortifies the macula of the eye. The macula filters out blue wavelength light from the sun and artificial light, suppressing the oxidation of retinal cells that can otherwise cause degenerative eye disease. More recent studies have intimated that Lutein supplements may also increase macular pigment in people at earlier stages of age-related macular degeneration (AMD), suggesting that a much larger group of at-risk individuals than previously thought may gain some benefit from taking the supplements. Age-related macular degeneration is the leading cause of blindness in the western world, affecting an estimated 30 million people worldwide. This number is expected to double by 2030.
