Sunblock and Vitamin D
by: Kerri Knox, RN- The Immune Queen

Yes, sunblock has a serious effect on the production of Vitamin D in the skin. It completely blocks out the rays that allow the skin to make Vitamin D.

This is one of the reasons why people in the US have such extensive Vitamin D Deficiency. Unfortunately, sunscreen may have some negative effects on your skin that you may not be aware of.

You see, there are two types of sun's rays that affect us, UVA and UVB rays. The SPF ratings on sunscreen tell you how effectively they block out UVB rays that make you BURN. But UVA rays are actually the more DAMAGING rays that cause sun damage and skin cancer.

So, one of the effects that sunscreen MAY have besides blocking production of Vitamin D, is to give you a 'false sense of security' as to how long you can stay in the sun and you may actually be doing MORE damage by staying out all day in the direct sun with sunscreen on than you would if you were be out in the sun WITHOUT SUNSCREEN, but being extraordinarily careful not to allow yourself to get burned!
