How Much Sun to Produce Vitamin D?

calcium vitamins

We are at a time in our lives where it has been advised to increase our intake of calcium.

In order for the calcium to be absorbed into the bones, we also need to take a Vitamin D supplement which aids in this process.

Trying to keep everything as natural as possible, I know that Vitamin D can be obtained by getting exposure to the sun's ultraviolet B-rays.

When these rays hit the skin, it causes a reaction that allows the skin cells to manufacture vitamin D.

But just how much of these rays get the job done?

From what I have been reading, it takes 10-15 minutes of the sun on your face and arms for the body to manufacture enough for two to three days. Also - be sure to not wear any sunscreen during this exposure time - it blocks the rays needed to produce this vitamin.

So, 10-15 minutes in the sun a couple times a week should be an inexpensive, natural way to get this important vitamin.

But, as a side note, if you live in the north, as we do, this only works during three seasons of the year. In the winter it is necessary to add a vitamin supplement to make sure we are getting the required daily amounts.


  1. thanks for sharing this wonderful health article. It is really important that we never take vitamin d for granted.

  2. This is important information as many parents are so worried about protecting their children from the sun that they lather them up with sun block and subsequently these children don't get enough vitamin D. We all need a little bit of it at least.
