Vision Guard plus because research confirms the use of certain nutrients to support visual function, Solgar created this well-balanced formula providing many of the key nutrients, which may be beneficial to help maintain the health of the eyes, including the important carotenoids, lutein and zeaxanthin.
This advanced formula contains natural source lutein and zeaxanthin extracted from the marigold flower as well as a natural source beta carotene/carotenoid mix instead of just beta carotene on its own, since emerging research is revelaing that several carotenoids in combination have more potent antioxidant activity than beta carotene alone.
If you ever wondered why an apple turns brown after you cut it or why iron rusts when exposed to the elements, you are questioning the damage and destructive effects of oxidants (free radicals) normally found in the environment. Oxidation causes similar harm to the cells of your body. When you breathe, digest food, exercise or just sleep, your body produces potentially harmful agents called, free radicals.
The free-radical chain reactions in your body take place countless times each day. To make matters worse, emotional stress, ultraviolet light and toxic substances in air pollution and cigarette smoke also generate free radicals that can put your health at risk. Fortunately, nature offers the means to protect yourself against the hazards of oxidation by-products. You can call on powerful allies known as, antioxidants, that work in opposition to free radicals.
