Thanks for all your help. Like Radgirl said, this does highlight the danger of taking any non-prescribed substances, even "supplements". Right now I'm keeping a log of what I'm doing and what I'm eating everyday so that if my next test is still off I can see what may be the cause. My levels have come down drastically since January so I'm pretty sure it was the supplements but now I'm trying to look into whether eczema may affect the liver as well.
