VITAMIN D.....useless....Dr. Mercola's reply
By Dr. Mercola The Vitamin D Controversy Heats Up
As for HOW to optimize your vitamin D levels, I firmly believe that appropriate sun exposure is the best way. In fact, I personally have not taken a vitamin D supplement for three or four years, yet my levels are in the 70 ng/ml range. There's a handy smartphone app called DMinder (dminder.info) that will tell you how much UV radiation you're getting and how many IUs of vitamin D you're making based on your local weather conditions (reported from the weather service) and other individual parameters such as your skin tone and age. It will also tell you when to get out of the sun, to protect yourself from sunburn.
