I went to the doctor a few months ago complaining of being so tired I didn't want to get out of bed. They checked my vitamin d levels to find I was at 17 when the lowest they would like to see you at is 50. I've been on 2,000 iu's of Vitamin D3 (make sure you use d3 not d2) and feel soooo much better. I actually have energy now! I started my husband on it and it has helped him tremedously as well. Most people are vitamin d deficient and EVERYONE should be on 1,000 iu'd a day at least! I haven't gone back yet to check to see what my levels are now. It has been about 3 months. Everyone has to ASK their doctor to check their vitamin d levels. I wonder how many years I have suffered needlessly. From what I'm reading, when you are as defecient as I was, your dosage should be higher than 2,000 iu's. I will go get my levels checked and then if they are still low, up the dose.
