I have been really impressed with this powder. I was a bit skeptical about putting this in smoothies and yogurt and such, but can attest it does dissolve really well and is tasteless! It also incorporates well in baked goods. I am impressed, and happy for help in meeting my protein goals while pregnant. I have noticed a difference in satiety as well after adding it.
Like other reviewers, I do notice a taste when I add it to coffee- it isn't unpleasant and doesn't change the texture, but is different. You may not taste it if you use sweetener or other flavorings in your coffee.
My only other note is that the bag doesn't shut for me; the powder has gotten into the ridges, and is quite sticky so I have been clipping it. You may want another bag or package to put the powder in if you have the same issue.
