Vitamin D supplementation - how will it help me improve my health?

Vitamin D 

Imagine a line stretching across the U.S. from Philadelphia in the East to just north of San Francisco in the West. That's about 40 degrees latitude. If you live north of that line, chances are, you're not getting enough vitamin D. And even if you live in the more southerly latitudes, if you're not getting outside to enjoy the sunshine for at least 15 minutes each day, it's pretty likely you're not getting enough D either. Likewise if you're dark-skinned, overweight or older.

That's because most of us get our D vitamins through sun exposure. When exposed to the UV rays of the sun, compounds in the skin work to convert chemicals into vitamin D. People in more northern latitudes are seasonally limited to the amount of sun they receive, and for those who have dark skin or who are older, the skin isn't as efficient at converting sunlight to vitamin D.

Vitamin D is different from other vitamins because it's available in only a few foods -- mostly fatty fish and mushrooms that have been exposed to UV rays. As a result, vitamin D supplementation is typically the best way for most people today to ensure that they get enough of the vitamin.

Until just a few decades ago, vitamin D's effects were largely believed to be solely related to healthy bones. Researchers understood that vitamin D helps the body absorb calcium, which is essential for healthy bone development. But more recently, evidence has surfaced that's shown there's much more to this vitamin than originally believed. 

Strengthening Bones and Muscles

Multiple studies have shown that the risk of fractures, especially among older people, is significantly higher when vitamin D levels are low. In a summary of evidence found in 12 studies, researchers determined that taking vitamin D supplements reduced hip and other non-spinal fractures by 20 percent.
