Vitamin D Could Help Overcome Vision Impaired

As you age, the elderly will experience a decrease in visual acuity. Fortunately, researchers found vitamin D can overcome this disorder in the elderly. In addition, vitamin D is also useful to improve fitness and dispel Alzheimer's.

British researchers found vitamin D supplements could potentially be a simple and effective way to cope with aging eye diseases like macular degeneration.

Macular degeneration is a condition where the macula (center of the retina and the retina of the most important part) suffered a setback resulting in decreased visual acuity and can cause loss of vision.

The study used mice that show the effects of vitamin D has been seen in just six weeks. Scientists believe many people in developed countries vitamin D deficiency is thought to be important in maintaining the blood supply to flow to the retina.  

who led the research explains the small blood vessels that supply blood to the retina is blocked by small molecules from time to time, causing inflammation.

In humans, this can lead to decrease in the number of light receiving cells within the eye up to 30 percent when aged 70 years and lead to reduced vision.

However, when one year old rats were given vitamin D supplements and injected with safflower oil containing 0.9 micrograms of vitamin D every three days, the accumulation of toxic molecules called amyloid beta is reduced. The mice were also increased vision capabilities.

The researchers found this idea after examining other findings showing that vitamin D can reduce the buildup of amyloid plaques in the brain. This buildup is known related to the development of Alzheimer's disease.

Rats that were given supplements also experienced a reduction of amyloid in blood vessels, such as aortic vessels. This suggests that vitamin D may also be useful to help prevent various health problems due to age, from reduced vision to heart disease.

Although vitamin D is contained in some foods such as fish and egg yolks, 90 percent of vitamin D is produced by the skin with the help of sunlight. Many people do not get enough sunlight to produce adequate vitamin D.

That researchers need to run clinical trials on humans before we say with confidence that the elderly should start taking supplements of vitamin D.

It is important to remind people that this is just an experiment. Many people are thinking of taking vitamin supplements without having to consult a doctor. Taking high doses of supplements can cause health problems
