Lutein AB Complex by Airbiotic exclusive lutein formula with plant extracts and vitamins that contribute to the normal maintenance of vision. It provides 20 mg of lutein in free form together with 2 mg of zeaxanthin per capsule .; In recent years there has been a growing interest in the carotenoid lutein. It is a yellowish substance that the body is not able to manufacture and that is obtained from the diet. "In free form" means that lutein is present in a chemical form similar to how it is found in food and is ready to be absorbed. However, some manufacturers use lutein in the form of esters (less easily absorbable) without the labels specifying this important detail well. Lutein Complex also provides myrtile, blackberry and grape seed that improve the utility of lutein and zeaxanthin. The formula is completed with vitamin A, known to help maintain adequate vision. It is recommended to take daily, with a meal. Do not ingest by pregnant or lactating women. Suitable for vegetarians. Store in a cool, dry place protected from light.
