In addition, a high level of vitamin D in the body is associated with a lower rate of virtually all types of fractures.

3. Rejuvenates Aging Eye

According to a 2012 study published in the journal Neurobiology of Aging, vitamin D3 plays a key role in the prevention of macular degeneration related to age, which it is the most common cause of blindness in the elderly.
