Question concerning absorption.

Okay, I am wondering something. I have read that urine contains all the enzymes, hormones, vitamins, and minerals that we do not digest and it is sent out through the body. My question is, when you drink the urine, what stops our body from just disregarding the nutrients again? When we drink the urine, does the body absorb all of the nutrients, or does it just send it out again like before?

Just wondering! :) Thanks. Tweet
