The very best protein powder I found is called Nectar. It is made by Syntac and can be found online through www. bariatricmart.com. It is by far the tastiest I found and makes drinking protein drinks enjoyable. All the flavors are fruity and when you mix it with flavored water, it's delicious! So far, I've had strawberry kiwi, fuzzy naval, and roadside lemonade. The lemonade is my favorite when I mix it with lemon flavored water. They have a variety of flavors and they all mix well. If you happen to bite into a little that didn't mix in, it's still fruity. You get a 2 lb. tub for 31.99. Yes, it's expensive but it lasts a long time and it's really good. It has 23 grams of protein per scoop.
Good luck on your protein search!
