I assume your level was measured as ng/ml?
With a level that low you should really take 8-10,000iu a day for 8 weeks then retest. If your levels have increased to a reasonable level at that point AND you feel better than you can take a maintenance dosage of 5000iu a day. That is unless you weigh more than 150lbs. If you weigh more, you have to take more.
We recommend maintaining a “healthy” level of 50ng/ml. At levels below 40ng/ml, your risk for cancer and autoimmune disease rises “dramatically”.Answered by
