From what I understand it’s made from pea flour although I’m not sure. I saw this article and it had me worried if the pea protein isolate powder I bought is absorbable. https://www.rebeccawood.com/five-elements/fire-element/pea-flour-looks-good-label-doesnt-digest/
If its not absorbable then the placebo effect is on a whole other level than we ever thought because i used it for my protein shakes for a year after workouts and it definitely made a difference as far as gains went. I stopped because i heard/read that it has a lot of contaminants on average (heavy metals in particular)
