Thankfully, the NUT suggested that as a second Protein drink I can try Proticas Profect- 25g of Protein (2.9 oz/day.) Ordered Fresh Citrus Berry from Amazon. I am happy to say, that this is a much welcomed item after choking down (literally) some of the protein shakes. Tastes ok and it's is only a little to drink. Also, they come in "virtually unbreakable" test tube-like containers, so they are very easy to toss into my purse.
Contains collagenic protein isolate & whey protein isolate... but I'm not even going to pretend that I understand all of that!! I just know it was on the list of approved items
