I had a blood test for Vitamin D levels a few years ago. I was very deficient. Very. My doctor prescribed 50000 iu prescription dose 1 x per week + 2000 iu 2 x per day D3 (over the counter). My blood levels were checked frequently. It took a full year of this before my blood levels of Vitamin D reached the lowest minimum level. I no longer take the prescription D. I do continue to take OTC Vitamin D3 and have blood levels checked annually. Vitamin D seemed to help my moods and my energy. By all means, talk with your medical professional, do research, and make your decisions based on your situation.
it's amazing how many people don't know that you need more than the 800iu they says is the recommended dosage. Dr. Mercola has done tons of research on this subject. I found out a few years ago too but you've done it the right way by talking to your dr. hopefully your blog will inspire ppl 1955 days ago
