I drink the Bariatric Advantage ready to shake shakes. The chocolate and strawberry are really yummy. The vanilla is pretty good, but I find it's missing something. There are 15 grams of protein in each shake. They come in a bottle with the powder and then you just add water to it.
I order them from
www.bariatricadvantage.com
I also take the BA chewable vitamins.
They sell a sampler pack of there products (protein and vitamins). It's a good way to see what you like.
Good luck!
