I was paraphrasing from the article I linked.
Here's my understanding of the absorption thing:
If you are given a known dosage of magnesium and then excretion of same is measured, the more you absorbed the LESS you originally had in your system or the MORE deficient you were. The example cited is that a 20% absorption would indicate NO deficiency, while a 50% (or greater) would show a significant deficiency.
