Eyesight Improvement with Vitamin D

by Health News

You’ve probably heard what recent studies have concluded about vitamin D boosts you immune system naturally, and how it can be an invaluable ally during flu season. And you’ve no doubt heard the more recent news that vitamin D might protect against the ravages of type II diabetes. But here’s another amazing benefit this vitamin might offer: strengthen your eyesight as you age.

Eyesight Improvement with Vitamin DDr. Glen Jeffrey and other researchers at the University College of London Institute of Ophthalmology in the UK conducted a study* in which they treated middle-aged mice with vitamin D for six weeks. For the treated group, one-year-old female mice were injected with safflower oil containing 0.9 micrograms of vitamin D every three days.  One mouse year is roughly 50 human years.

After six weeks, tests measuring the electrical responses of retinal cells showed significant improvement in the vision of the treated mice. So, what is the mechanism behind these very promising results? According to Dr. Jeffrey, it has to do with the reduction in amyloid deposits and inflammation in the blood vessels—a finding that could have even broader implications beyond those gleaned from this study.

“Finding that amyloid deposits were reduced in the blood vessels of mice that had been given vitamin D supplements suggests that vitamin D could be useful in helping to prevent a range of age-related health problems, from deteriorating vision to heart disease, " says Dr. Jeffery.

Ask your health care professional about the best way to incorporate this important nutrient into your supplement regimen.
