How do you get enough Vitamin D from the sun?  If you can fulfill the following, you might get enough:

1. You live south of Atlanta in the winter.
2. You are in the sun from 11:00 am to 1:00 pm.
3. Your body is mostly uncovered.
4. You go without sunscreen for at least 15-20 minutes.
5. You don’t use soap for 48 hours.
6. You repeat the process in 72 hours.
7. Your skin is not dark, either from genetics or suntanning. (You may need six times as much exposure if your skin is dark.)

Unless you fit all of these conditions, you need to supplement.  And a multi-vitamin or calcium plus D supplement will NOT have enough Vitamin D, nor will your milk.  You need to supplement with high iu Vitamin D3, preferably above 4000 iu.  If your blood 25 hydroxy D test is below 70 (ignore “high”, “medium” and “low” because that is based on the averages of a D-deficient population,) then supplement it.  The exception is if you have scleroderma or similar abnormal calcium metabolism.

Other ways to supplement:  frequent consumption of liver, preferably from organic animals.  Shitake or other mushrooms dried gill side up in the sun on a daily dose of about one ounce dry weight, cooked long and low.

Calculations from studies on Vitamin D show that, for every person who dies of skin cancer from UV overexposure, more than two hundred will die from other cancers, like lung, breast, prostate and colon, as a result of low vitamin D levels.
