The lutein extract powder is a carotenoid with natural properties that have been extracted from marigold flowers and then saponified and purified to generate a lutein product in its free form that is more stable. Lutein is an eye-health nutrient, one of the most well-known of all eye-health nutrients today. Because we cannot make our own lutein (we can't synthesize it). Therefore, it is important to have a daily dietary intake and supplementation to maintain healthy levels of lutein in our bodies.
Lutein is classified as a yellow-orange pigment found in plants, and it is commonly associated with the petals of marigold flowers. For nutraceuticals, functional foods, and animal nutrition, lutein is also a common ingredient. Many consumers and product formulation professionals are seeking out natural alternatives to synthetic-based products that can meet the criteria of providing clean label, healthy, and multifunctional products.
