Benefits of vitamin D introduction


Vitamin D is commonly known as the sunshine vitamin? Why? Because sunlight is of the ways vitamin D can be obtained. You may be surprised to find that even though vitamin D is called a vitamin it isn't an essential dietary vitamin as most mammals with the exception of cats and dogs can synthesize vitamin D when exposed to enough sunlight.

Think about it in winter time there is a much higher rate of influenza this has been linked to the low level of vitamin D in winter time. Historically vitamin D is used to treat tuberculosis.
