Revealed: how vitamin D can protect us from cancer

“It is the first time that scientists have found direct evidence to suggest that the “sunshine vitamin”, which is made by the skin in the presence of sunlight, directly controls a network of genes linked with a wide variety of serious disorders”.

Vitamin D is produced naturally by the skin but only in the presence of sunlight

We screened the whole genome and found all the sites where vitamin D binds. The evidence is now quite solid that not only is there binding but we’ve been able to show that it actually affects the functioning of the gene. It’s not just sticking to that region, it’s actually altering gene expression,” Professor Ebers said.

Vitamin D is produced naturally by the skin but only in the presence of sunlight. Sunshine contains ultraviolet light B (UVB) which converts a ubiquitious precursor substance in the skin, called 7-dehydrocholesterol, into vitamin D3. This can then be converted by the liver and kidneys into the biologically active form of vitamin D.

By far the easiest and best way of delivering enough vitamin D to the body is to expose unprotected skin to direct sunlight for a few minutes each day. But light-skinned people are advised not to burn their skin.
