The Dangers of Vitamin D, and You Could Be Getting The Wrong Test?

When seeing your health care professional about vitamin D testing, make sure they order the correct blood test. Since the correct testing for vitamin D may not be well known, it’s important to confirm that you’re getting the right one. There are two vitamin D tests: 1,25(OH)D and 25(OH)D.

25(OH)D is the better marker of overall D status. This is the marker most strongly associated with overall health. The correct test is 25(OH)D, also called 25-hydroxyvitamin D. When dealing with your blood test levels, be aware that many commercial labs are using the older, dated reference ranges. I’ve been told by cancer specialists, including Dr. Mercola, that we should all be in the range of 50 and 70 ng/ml if we do not have a history of cancer, and up to 100 ng/ml if we have a history of cancer. This applies to everyone, including children. If your levels are below 32 ng/ml, you may be at serious risk for many illnesses, including cancer. That’s why it is so important to have your levels tested 3 to 4 times a year initially, until you get into a comfortable groove with your range.

But Be Careful….

You may be wondering if there are any risks associated with vitamin D3 supplementation. As with any supplement or lifestyle changes, it’s very important to see a doctor first. A simple blood test can show you where your levels are, giving you a better gauge on the appropriate therapeutic dosage for you. Remember, everyone is different. This is an issue of genetics and biochemical individuality. Therefore, some people may need 10,000 IU or more daily to improve their levels, while others may find that anything over 200‑400 IU puts them in an overdose situation. That’s quite a difference in dosage, so you can see why it’s so important to test your levels regularly until you know (a) that you’re at the correct levels and (b) how much you will need to maintain those levels.

People with lymphoma, sarcoidosis, or tuberculosis need to be particularly careful, since these issues can cause a disruption in the way vitamin D is metabolized, leading to high levels of calcium in the blood. In this case, it’s vitally important to consult a medical practitioner.

It’s also important to know that adequate calcium and magnesium, as well as other minerals, are critical parts of vitamin D therapy. Without calcium and magnesium in sufficient quantities, vitamin D supplementation will withdraw calcium from the bones and allow the uptake of toxic minerals.

So it’s not cut-and-dried, one-size-fits-all, but you can see how important it is to check into this and to do it properly. Most of all, enjoy those beautiful rays!
