lutein and zeaxanthin supplements

Lutein is a fat-soluble pigment. Belongs to the Carotenoids group. Carotenoids can be divided into two broad categories: carotenes. Such as β-carotene and lycopene. And xanthophylls. Such as lutein and zeaxanthin. Lutein exists in other parts of the human body such as the human eye (retina, rod-shaped outer segment, lens). Including skin, brain and breasts.

If you can take 1 bowl of spinach or kale daily, you can get the recommended amount of 6 mg of lutein per day. But beware, these foods should not be cooked for too long.
