Zinc for Vision Health
Zinc is a chemical element with symbol Zn and atomic number 30. This essential trace mineral is found in all parts of the human body and is vital for many biological functions. The element helps promote immune health, has a role in wound healing, and supports healthy cell growth.
It may also have a positive effect on vision health. The critical mineral is known to enhance the effectiveness of vitamin A, a carotenoid which is vital to eye health. In addition, research has also found that high intake of the element is associated with a reduction in early vision problems and macular concerns. In May 2013, one large eye study indicated that a precise combination of zinc, lutein, zeaxanthin, vitamin C, and vitamin E helped support eye health and preserve vision.
A wide variety of foods contain the element. Oysters are the best source, containing more per serving than any other food. Red meat, poultry, and seafood, such as crab and lobster are also good sources.
Beans and whole grains also provide some amount of the element. However, these foods also contain phytates which bind the element and inhibit its absorption. Thus, the bioavailability of the element from grains and plant foods is lower than that from animal foods.
- People who have had gastrointestinal surgery, such as weight loss surgery, or who have digestive disorders, such as ulcerative colitis or Crohn's disease. These conditions can both decrease the amount of zinc that the body absorbs and increase the amount lost in the urine.
- Older infants who are breastfed because breast milk does not have enough of the element for infants over 6 months of age. Older infants who do not take formula should be given foods that have zinc such as pureed meats.
- Alcoholics because alcoholic beverages decrease the amount of the element that the body absorbs and increase the amount lost in the urine. Also, many alcoholics eat a limited amount and variety of food, so they may not get enough of the element.
In addition to your diet, supplementation is a popular way to ensure you’re getting enough of this essential element. Our Bi-Optium Eye Health formula contains 11.3 mg of zinc to support for your maculae and preserve your health vision.
