Vitamin D Deficiency (Part 2)

In part one of the vitamin D discussion, I reviewed how highly prevalent a vitamin D deficiency is, even in southern areas in the country with warmer climates. I mentioned that the current recommended dosage appears to be significantly lower that evidence suggests would be a necessary minimum dosage, and concluded that the best way to determine the necessary dosage is to be tested.

Currently, the two lab tests are 1,25(OH)D, and 25(OH)D. The later, which is also referred to as 25-hydroxyvitamin D, appears to indicate a true deficiency with more accuracy. The range of normal levels in the test is 20-56 ng/ml. However, even the low end of the normal range is probably too low. A more appropriate normal range appears to be at the high end, closer to the 56 ng/ml.

So what happens when you are low? First of all, join the club. So many of us, myself included, have tested deficient. The obvious solution is to get more sun exposure when possible. However, in some climates that is easier said than done. This is where oral supplementation comes in. Two possible supplements exist. One is cholecalciferol, otherwise known as D3, and ergocalciferol, known as D2. Research indicates that D3 is the better option, since the body is able to use it more effectively. Once supplementation begins, lab results should be monitored closed, every 4-6 months at first, until the optimal dosage becomes clear.

The good news is that this is a problem that, when properly identified and managed, is fairly easy to treat and control. A little vitamin D can go a long way to helping you live a longer, healthier life.
