According to Times of India, Vitamin D may not make you flexible, but is the ultimate anti-aging vitamin as you age. It may give you an edge when it comes to keeping your balance, your grip strength, and your foot speed.

Dangers of Vitamin D Deficiency
They also mention that a lack of vitamin D is actually fairly common in the US; up to 40% of people may not be getting enough. And shortfalls increase with age. This is not good, because a study recently revealed that people around the age of 65 and older who are low on vitamin D do poorly on tests of handgrip strength, walking speed, balance, and the ability to stand up from a seated position. More research is needed, but scientists feel there is already enough evidence of vitamin D’s positive effect on the muscle strength to warrant being on a D-alert.

Where to get yours
They go on to say that you can get your vitamin D from the sun and from food (including fortified foods), but most people need a supplement to get enough, especially as the winter sun rays get a little weaker.
