When I read the claim about no vitamin D in winter north of Atlanta, that did not make sense based on what I've read about solar radiation. Scientific research simply says that you cannot get a full daily requirement of vitamin D in the winter at higher latitudes, not that you can't get any.

A year ago I got tested, in March 2012. My vit. D levels were at 20 total, and anything less than 30 is deficient. All year, I tried to sunbathe at least twice a week for 20-30 minutes during the mid-day hours. I actually have a little bit of tan now. Yesterday at my doctor's visit they told me with my low levels, sun bathing isn't going to cut it and I need to take supplements for three months before I get tested again. I am disinclined to believe it. I live in Tucson AZ so we get enough sun all year.

Thank you! I know that I always fell soo much better when I spend 15 to 30 minutes 15 minutes a day in the sun. I am fortunate to live in New Mexico where it is sunny all the time but sometimes I get busy and can't spend 15 minutes outside so I joined a tanning salon and found that I can get the same results. I do not stay in the tanning bed for more than 10-12 minutes per session and I only go once a week. I also found out that I have a severe vitamin D deficiency and that getting sun is better than supplements but I still have to take supplements and recently found out I have hyperparathyroidism which is too much calcium and PTH in the blood and I am going to have surgery next week.

Someone told me 2 hrs. a day in the sun is what I needed to get the recommended amount of Vitamin D? Is this so?

I have known this for years. I work in an office and have always enjoyed styepping out into the sun for 10-15 minutes a day during lunch. It always made me feel better and I missed it during the winter.

OK, you said that as the older you get you need more time in the sun, but you do not say how much time for people over 50, 60 or 70. If the maximum time is 10 min. for fair-skinned people (which I am) how much time for us over 60?

I learned that vitamin D in supplement form is from Sheeps' wool and I have found one that is from mushrooms...all organic at www.touchstoneessentials.com
