protein ????
Check out www.bariatriceating.com. They have everything. I got a sampler basket for around $30 that had a lot of different flavors. I checked my powders & they have "dietary supplement" on them. A lot have "low carb" too. Hope this helps.
My dietician recommended a product from Wal-Mart. It is simply called "Whey Protein Instant Shake Mix". It can be used to build muscles, dieting, or just healthy living. It comes in Chocolate, Vanilla, and I think Strawberry too. And, it's the cheapest I have come across. Hope this helps. You can visit their website, also, at www.designerwhey.com.
