RNY Bypass patients using Casein

I had RNY bypass surgery Sept of 2012. Doing well so far, but I'm looking at getting more protein back in my diet and I'm looking for new supplement options. I've been using SEI Pharmaceuticals Max Protein for over a year with good results. It is made from 100% whey protein. My question is this: I want to try a different highly recommended brand for a different flavor, however it's a protein blend that contains Casein. My research basically leads me to believe that Casein is essentially a time-release protein. Well for those of your with RNY surgery know that time-release medications don't work for us. It's all absorbed at the same time. I'm wondering if any of you have had an ill-effects from using something containing Casein.

Before you comment, yes I know the best option would be to ask my surgical group and RD, however they are notoriously hard to get hold of unless you schedule an appt. So I wondered if anybody on here who had bypass surgery could tell me their experience with it, if any.

    nope I haven't BUT I have learned that you most likely will get a response from someone who has... just keep bumping it up (by posting) some just write in 'bumping' there is a site called bariatricpal.com you may get great advice on the supplements there.

    Thanks for the reply. I didn't know about that forum. I'll probably ask there, as every single one of them has had WLS instead of many here that haven't.

    Do you drink milk? Milk contains casein and whey. Casein is a natural protein, not a medication. 95% of absorption of nutrients occurs in the small intestine, so I don't see why you would have an issue absorbing casein.

    Just wanted to say thank you. You're right, dairy milk protein contains approx 80% casein. I guess that takes care of that question. I've had milk before but have recently switched over to almond milk. Regardless, thank you.

    If you are interested, here was my reason for questioning it. Because I've had RNY gastric bypass surgery, I have no stomach that holds food. I have a pouch that contains no valve between the small intestine and "stomach". Liquids and foods slide freely (for the most part) into the small intestine. Time release medication is meant to sit in the stomach for hours an be slowly absorbed. In my system, it would fall into the intestine within a few minutes of being taken and be absorbed all at once. It's the same reason why a few sips of wine get me drunk within 10 minutes of having them.

    My concern was that casein tends to form a jell in the stomach of a non-rearranged person. So in my case, I was afraid that it would form a jell in the small intestine, which could lead to a block. Blocks in the small intestines are bad news. Regardless, I'm probably overthinking it.
