I cannot stress how disappointed I am in the changes to this product. I tried it first about 1 year ago and loved it. Now I've ordered 2 40 oz. packages and found it to be completely different. The old stuff mixed in ok, but stayed a little grainy. I didn't mind that, and loved that it had almost no taste. Now it dissolves after a lot of effort, but tastes absolutely horrible. It has a bitter taste that I can't put my finger on, even mixed with chocolate milk. Even the color changed from off white to yellow. I would recommend that you ignore any older reviews for this product, as it has changed and is nothing like it was.
