Complementary feed that provides nutrients to the lens.

Lutein and Zeaxanthin: Help to protect the lens by decreasing the progression of opacities (nuclear cataracts) in humans (1). In in vitro studies, they protect against oxidative damage (2).

Minerals (Zn, Cu): Essential for eye development; help slow visual acuity loss in humans (8, 9, 10).

Vitamins (A, C, E): They have been seen that help to prevent nuclear and cortical cataracts in humans, reducing the risk of cataract development (6,7). Invitro studies show antioxidant action (1).

Vitamins (D3, K): Related to the metabolism of insulin and glucose (6). They have been linked to reducing the progression of cataracts in humans (6,7).

Vitamin D shows anti-inflammatory action (5).

Minerals (Ca): Helpful in cataracts that occur due to hypocalcemia (8); helps slow down the progression of lens opacities in humans (5).

Vitamins (B1, B2, B3, B6, B7, B9, B12): Important for the activation of some antioxidants and the depletion of homocysteine, helping
to slow the cataract onset in humans (1,9,10,11).

Alpha lipoic acid: Antioxidant effect (12). Helps to protect retinal ganglion cells in diabetic retinopathies (13).

Aldose Reductase Inhibitor (sorbitol generator) (14,15). Slows down the progression of diabetic cataract in dogs (16).
