Why Natural Stacks Eye Defense?
Modern technologies tax our eyes more and more. We make more use of screens during the day, which generate different light than natural sunlight or firelight, to which our eyes are adapted. Extended exposure to artificial light can cause short-term discomfort, such as dry eyes, but on the long-term, it can contribute to age-related reduced eyesight and increase the risk of other age-related eye problems.
Large amounts of blue light, which is produced by screens and artificial lighting, can cause damage to the eyes in the form of oxygen radicals. Especially the macula lutea region of the eye (the 'yellow spot') is very sensitive to blue light. The lens of the eye focuses incoming light onto the macula, where the colour-sensitive cells are located.
Because of the crucial function and relatively high light load of the macula, it is very important to take good care of it when you are using a lot of artificial lights or screens.
Nutrients in Natural Stacks Eye Defense
With the right nutrients, you can help protect your eyes from such influences. Natural Stacks Eye Defense contains the following nutrients to accomplish this goal:
Vitamin A as beta-carotene
Beta-carotene has long been known as an eye-supporting vitamin. After all, weren't you always told to eat your carrots because they make you see better (carrots get their orange colour from carotenes)?
Vitamin A contributes to maintaining a normal fluid balance of the eyes and helps maintain normal eyesight. Vitamin A also helps maintain normal mucous membranes and the normal function of the immune system. The last two processes are naturally very important for protecting sensitive sense organs like the eyes, which are constantly being exposed to various irritants and damaging influences in the environment.
There is very little risk of a vitamin A overdose with beta-carotene supplementation. Beta-carotene is a precursor of retinol, which can, in turn, be converted to active vitamin A. The body only converts beta-carotene to retinol when more active vitamin A is needed.
Vitamin E as alpha-tocopherol
Because a part of the damage caused by blue light comes in the form of oxygen radicals, you can support the eyes with antioxidants. A powerful antioxidant is, for example, vitamin E. The most common and well-studied natural form of vitamin E is alpha-tocopherol.
Vitamin E functions as an antioxidant specifically in the skin and other areas of the body exposed to direct light.
Lutein & Zeaxanthin from marigolds
Lutein and Zeaxanthin are plant pigments that also play roles as nutrients in the body. Lutein and Zeaxanthin are also known as macular pigments.
Lutein and Zeaxanthin are essential (can't be made by the body) and must therefore be gotten from food or supplements. Natural Stacks Eye Defense contains Lutemax 2020, an extract from marigold flowers, which contain the natural forms and ratios of Lutein and Zeaxanthin.
Sea Buckthorn oil
Sea Buckthorn is a bush found along the coasts of Europe and the Middle-East, to the inland of Asia. The plant is mostly known for its small, bright-orange berries that have been used in traditional medicines in the regions where the plant is found.
Sea Buckthorn contains a lot of nutrients, including vitamin C and E, but also beta-carotene and Lutein & Zeaxanthin.
