About Bio-Vision
Bio-Vision is a dietary supplement developed specifically to support the eyes, eye mucosa and eye blood vessels. Among the active ingredients are beta-carotene - a precursor of vitamin A (retinol) - which along with zinc, contributes to the maintenance of normal vision. Ingredients such as copper, vitamin C and vitamin E will help to protect cells against oxidative stress. Amdexyn Vision also contains lutein and anthocyanidins derived from blueberries.
Why do we need to supplement?
Being able to maintain a normal sight contributes to the quality of life. Our eyesight changes as we get older, which is inevitable, but with Bio-Vision we can counter some of the negative effects of oxidative stress that the eyes are exposed to, from pollution, UV rays and even our own metabolism.
How does it work in the body?
Antioxidant nutrients
Bio-Vision contains a range of potent antioxidant nutrients including vitamins C and E and beta-carotene, and the elements Zinc and Copper.
These nutrients can play a role in reducing the risk of developing degenerative eye conditions, such as age-related macular degeneration (AMD). AMD is a major cause of significant vision loss in older people and is believed to be caused by oxidative stress. The Age-Related Eye Disease Study (AREDS), a large randomized clinical trial, found that participants at high risk of developing advanced AMD reduced their risk of developing the condition by 25% by taking a daily supplement containing antioxidants, including vitamins E, C and Zinc and beta-carotene 1.
Lutein is one of 600+ known naturally occurring carotenoids produced only by plants such as carrots, spinach and kale. In the human retina, lutein is absorbed from blood specifically into the macula - an oval-shaped pigmented area near the centre of the retina of the eye. Lutein can help protect the macula from oxidative stress, known to be a driver of eye diseases such as AMD. Various studies show that Lutein intakes and retinal concentrations are associated with reduced risk of developing AMD 2,3.
Blueberry is a source of anthocyanins - deep blue pigment flavonoids which are responsible for the berry’s colour. Anthocyanins can offer antioxidant protection to the tissues of the eye, supporting general eye health. Blueberry is also a source pterostilbene shown to help prevent inflammation of the eye which can be a driver of various eye diseases 4.
