Many of you may have read the report that was released at the end of November saying that the recommended level of vitamin D may be too high. Currently, the recommended level is 30 or higher, but according to the report released by the Institutes Of Medicine, a level of 20 should be OK.
It is important to note, this report only looked at people who were healthy, it did NOT look at people with osteoporosis. It also only looked at bone health - it is still not clear what the ideal level is for your immune system, and there is mounting evidence that vitamin D does play an important role in maintaining a healthy immune system.
So if you are healthy and your bones are in good shape (i.e. you do not have osteoporosis) - a level of 20 is probably OK, although there is nothing wrong with a level of 30 or 40. However, if you do have osteoporosis, then you should still shoot for a level of 40 to 50. Vitamin D does not become toxic until your level gets over 100.
