Does the rice protein taste pretty good?

My daughter uses rice protein.

I’d suggest creating your own. Unfortunately we haven’t found one either. I’ve powdered up seeds, put some cacao, some powder banana etc, and GF oats powder of coarse.

There isn't a protein shake out there that I've found, that can be guaranteed not cross-contaminated with treenuts and peanuts. Thus, you might want to do trial and error of cooked eggs (raw not recommended) blended with watercress, napa cabbage and allowed fruits.

You could check this manufacturer out. https://www.nutribiotic.com/rice-protein.html Its a rice protein that pure rice protein, but does contain vanilla flavoring.
