Vitamin D

Why we need Vitamin D

To prevent osteoporosis, depression, prostate cancer, 

breast cancer, and even effects diabetes and obesity. 

It regulates over 200 genes in cells all over the body including the brain, heart, kidney, bone, intestine, skin, gonads, prostate, breast, parathyroid gland, and immune system.

There is one secret reason why we all love holidays in the sun(especially those of us in Ireland) and that secret is Vitamin D.The sun is the main source of vitamin D, 

Our Vitamin D needs vary with age, body weight, percent of body fat, latitude, skin coloration, season of the year, use of sun block, individual reactions to sun exposure, and our overall health. 

As a general rule, older people need more Vitamin D than younger people, large people need more that small people, fat people need more than skinny people, northern people need more than southern people, dark-skinned people need more than fair skinned people, winter people need more than summer people, sun-phobes need more than sun worshipers, and ill people may need more than well people.
