Nature's Plus presents unrivaled nutritional support for healthy eye function: Ultra Lutein. In Ultra Lutein, maximum strength active ingredients lutein and zeaxanthin combine to form an antioxidant powerhouse that helps to reinforce ocular well-being. Ultra Lutein's FloraGLO brand of lutein is an active carotenoid derived from concentrated marigold flower extract, formulated with an exclusive, patented purifying process. While lutein is found in many common foods, most adults may not get sufficient quantities of this beneficial nutrient for their daily diet. Scientific studies indicate that 20 mg of lutein is critical threshold of efficacy for adults who need to support healthy eye function - and 20 mg of FloraGLO lutein is precisely what each Ultra Lutein softgel contains. The cofactor in Ultra Lutein, zeaxanthin, also a marigold derivative, synergistically enhances lutein's natural antioxidant strength.*  Note: Unless otherwise noted, this product has not been evaluated by the Food and Drug Administration.
