A whole blood histamine test showed a low histamine level (25). But I had been taking a LOT of niacin for several weeks. (Didn't take niacin for 12 hours before the test though). I'm a little concerned now that the niacin lowered the blood histamine , making me think I'm an over-methylator when I'm not. I don't want to take folic acid if I'm actually an undermethylator. Niacin has been a life-saver to me, though, for anxiety. Up to 3 grams a day.
