I was organizing some old files today and came across my Spectracel.coml vitamin deficiency test, which shows if your cells are actually absorbing a vitamin or not. Standard blood tests only show if the vitamin is in your system at the time. Although I was low on vitamin D and borderline low on a few other vitamins/minerals (which matched standard blood test results), vitamin A was the only one I was not absorbing. I took a standard blood test for vitamin A shortly after this test, which showed normal levels. So, although a vitamin level shows in normal range on a standard blood test, you might not be absorbing it. I don't think I was absorbing it because it is a fat-soluable vitamin. My vitamin D levels may also be lower for that reason, but I am still aborbing it so maybe vitamin A is fattier or harder to absorb that vitamin D or I get a little sun to aborb whqt my intesyines could not. But people who took the drug Accutane took it because it is a synthetic version of vitamin A. Anyway, they must have been low on vitamin A to need that drug in the first place. It is possible that the drug fooled their body into believing it was producing enough vitamin A from the synthetic vitamin A so it stopped absorbing it to protec† the body from overdose. I don't know. Or the intestines could have been damaged in the same area my intestines were damaged from celiac.

Here's part of the report:

"Patients with celiac disease, Crohn's disease and pancreatic disorders are particularly suspectible to Vitamin A deficiency due to malabsorption. Vitamin A deficiency is also associated with strict dietary restrictions and excess alcohol intake. The immune system may be adversely affected, reducing white blood cells levels and impairing both cell-mediated and humoral defense systems.
