I read medical reports claiming that almost 100% of Kuwaitis suffer from Vitamin D deficiency, yes I know many friends and relatives with low-vitamin D when they make lab tests.
This is weird because unlike other vitamins, Vitamin D is made in the skin with the aid of the sun light and we have a long summer and plenty of sun light in Kuwait ! There are foods that contain Vitamin D such as fish, milk, liver egg yolk, or by taking tablets or injections.
Vitamin D helps in cancer prevention, stronger bones, growth among many other important body functions.
