Think Poison/"Vitamin A" toxicity is rare? It's not, and it's being found more and more every day!
From their "Health Risk Profile - Extended" page:
The vitamins measured are vitamins C (ascorbic acid), A (retinol), and E (tocopherol), with beta-carotene and lycopene. We regularly report deficiency levels of vitamin C and vitamin E, reflecting their often poor dietary intake. In contrast, we seldom find vitamin A deficiency, but report many high or toxic serum levels of this fat-soluble vitamin, which can reflect either excessive supplementation with vitamin A or displacement of the vitamin from hepatocytes as a consequence of chronic ethanol consumption. Levels of lycopene and carotene reflect intake the subject's intake of these carotenoids from fresh fruit and vegetable consumption.
Screenshot for posterity:
By the time serum retinol tests of Vitamin A are showing high, this is a sure marker that the liver is full of this poison and can't hold any more. Subclinical toxicity is happening at supposed "normal" levels of this non-"Vitamin" all the time as well.
