Yes, full body exposure to 15 minutes of summer-strength sun will make about 10 000 IU of vitamin D in your skin. However, during the winter in the north, the sun’s rays are not strong enough to make vitamin D so a supplement may be required. The ideal vitamin D blood level is between 50 and 80 ng/mL and a blood test of circulating 25 hydroxyvitamin D [25(OH)D] will measure this.
Sufficient amount of vitamin D is likely necessary to prevent many illnesses including the following: respiratory infections like the common cold; many cancers; osteoporosis; among others. It is also speculated that vitamin D will help prevent seasonal affected disorder (SAD), so in this sense, yes – sunshine makes vitamin D and it makes you feel good.
Skin produces vitamin"D" if expose to the sun. It is a vitamin that is needed, you can take it in a tablet form or by sitting in the sun get it free but must not put sunscreen or UV blocker and must be care full so you do not get sun burn. About 1/2 an hour a day on bear body (bikini is OK).
Amongst other things body does not absorb calcium from food such as milk or even pain calcium tablets if you do not have vitamin "D" in your system. Most calcium tablet will say with vitamin "D", use them if you cannot get the direct sun on you.
