Is it ok to protein powder in boxing training?

I get my protein from vagtables.

Which vegetables?

Which vegetables?

Broccoli, spinach, watercress, and black beans roughly 6 grams of protein in half a cup of those.

Natural protein sources better - peanut butter, yogurt, raw nuts, tofu. Fake food is fake food.

Quinoa also good protein source.
