Free radicals, or unstable molecules created by stress, lifestyle factors, and pollution, are responsible for many cases of age-related eye degeneration and visible signs of aging. LA Nutrition's Vision Defense is specially formulated to help defend against free radical damage and encourage sustainable ocular health along with a youthful appearance. Antioxidants are well known for their ability to fend off free radicals, so LA Nutrition has selected some of the most powerful natural antioxidant compounds, all of which are associated with healthy vision and cellular support. Vitamin A, lutein, and lycopene work together to protect the eyes and boost enzymatic activity that is important for proper ocular function. Grape seed extract and quercetin also lend antioxidant properties and have even been reported to be more effective than vitamins C and E in protecting overall eye health. N-acetyl-L-cysteine then detoxifies ocular cells for clearer vision. LA Nutrition's Vision Defense is a comprehensive supplement for healing, protecting, and rejuvenating the eyes.
