A Natural Remedy for Aging Eyes: Vitamin D

A Natural Remedy for Aging Eyes: Vitamin D

Vitamin D has been shown to reduce retinal inflammation and amyloid-beta accumulation. 

There is still little evidence for the health benefits of vitamin D, but recent researches may change this situation. The last one, published online in the Journal Neurobiology of Aging, offers promising data for the impact of this vitamin on aging eye: in only 6 weeks, its application on aged mice led to perceptible sight benefits.

“Treated mice showed significant reductions in retinal inflammation and levels of amyloid beta (Aβ) accumulation, which is a hallmark of aging,” the authors say. “They also had significant reductions in retinal macrophage numbers and marked shifts in their morphology. These changes were reflected in a significant improvement in visual function, revealing that vitamin D3 is a route to avoiding the pace of age-related visual decline.”

90% of vitamin D is synthesized by the body through sun exposure, but it could be administered in vitamin supplements as well, if these results are confirmed. The research is still at a very early stage, but all signs are positive. “Vitamin D could be useful in helping to prevent a range of age-related health problems, from deteriorating vision to heart health,” says Professor Glen Jeffrey, from the Institute of Opthalmology at University College London, and lead researcher of the study.
