Roll Call does not check drug interactions or assess personal safety.
A protein powder extracted and concentrated from rice, typically brown rice, used as a plant-based alternative to dairy or soy protein sources.
Why it’s used
Taken as a dietary protein source, often by those avoiding dairy or soy, including for general nutrition or muscle-support purposes.
What the evidence says
Dietary protein's general role in supporting muscle protein synthesis is well documented, but head-to-head evidence comparing rice protein specifically to other protein sources for that purpose is limited and comes from a small number of trials.
