I have the Apple Cinnamon flavor and let me say that I LOVE this flavor. It is without a doubt the best tasting whey powder I have ever tasted. Well done by the NP folks.
However, I have had major gastrointestinal issues since using it. If I use two scoops at once I immediately bloat and have major stomach cramps. I am attributing this largely to the Stevia based off what I have read about it online. Maybe I am allergic? or just really sensitive to tiny amounts of it?
