Hi. I just received my vitamin d results and my levels are 22.7ng. My doctor says that this is fine and is not low enough to contribute to my feelings of being tired, brain fog, irritability or restlessness. Do I need to supplement or is he right?
Your doctor is wrong. At levels below 30ng/ml, and calcium cannot absorb correctly from the intestines. At levels below 40ng/ml and your risk for cancer and autoimmune illness rises “dramatically”! Your symptoms are from being deficient. To correct a deficiency take 8000-10,000iu of D3 per day for 8 weeks. At the end of 8 weeks you should retest to make sure your levels have recovered enough. If all of your symptoms are gone in 8 weeks, you should then take a maintenance dosage of 5000iu for a person weighing an average of 150lbs. If you weigh a lot more than this, please let me know. It is very important to read http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-and-other-vitamins-and-minerals/. If you have any more questions, just ask!
