THE go to book on vitamin D3. It’ll change and prolong your life! I used to get colds with a 3 week sore throat afterwards, every year, sometimes twice a year. What I didn’t know, I was deficient in D3 (probably among other vitamins and minerals) I read this book and started taking 20,000 to 30,000 IU a day for a period, then finally backed off to now, 5000 IU a day. That was 3 years ago and I haven’t had a cold or sore throat since then. I attribute this to Vit. D3. Thank you Jeff Bowles. Goes to show, you don’t have to have the letters MD after your name to know more about proper nutrition and/or supplementation.
