Sunshine exposure and vitamin D levels have been shown to influence, pain, heart disease, diabetes, parkinson's, cancer, infections, weight gain, mental health and many other conditions. Now that Spring has sprung, and the midday sun has enough power to activate your body's production of vitamin D, it's time to review your vitamin D supplementation.

1) Get your 25 hydroxy vitamin D levels tested. If you are lower than 65 you need to supplement and/or get out in the sun.

2) Get 15 minutes of midday (11:00 a.m. to 3:00 p.m.) sunshine on your face and arms each day. Any type of sunscreen or UV coating on glass will stop your body from making the vitamin D. Many face creams and even make-up now has sunscreen added.

3) Take at least 2,000 i.u of vitamin D3 a day even during the summer.

4) If you cannot get out in the sun regularly you need to take at least 5,000 iu of D3 a day.

5) If your test shows your vitamin D levels are low, you can take as much as 10,000 i.u a day to recover from your deficiency.
