?? Health/Nutrition Stores??
Try www.vitalady.com
They have the best selection of proteins. You can even order sample packets from the web site before buying a 2 lb. container of something you discover you can't stand to drink. Most Nutrition/health stores don't have samples to try.
On this web site, you can email questions. The owners are bariatric patients themselves for over 10 years. They really know their stuff.
I have no affiliation w/ the company, just a very happy customer.
