absorbtion rate

this might be a more medical question but post RNY how much do we absorb of either a meal or a protein shake more important vitamins when we take them, if you dont know the answer pls dont post anything unless you know where I can get the research numbers thanks.

It really varies by how much your surgeon bypassed. If you want the most specific of answers, give your surgeon a call and ask.  Being a nurse, you can get some good descriptions that he may not give the average patient.

This varies SO much from person to person, and it's the reason that getting regular bloodwork done is so important. You and your friend may be bypassed the exact same amount, and you may both take in the exact same nutrients, but you may be only absorbing half what she's absorbing.
