Not hard to google that. There's even a website: https://www.greatveganathletes.com/ https://www.greatveganathletes.com/ I think that's a silly argument anyway, if we're discussing health. Professionals do plenty of stuff that is awful for them to get performance gains. Steroids, exercise routines that are very punishing on the body long-term (plenty of power lifters who can barely even walk after retirement and they aren't that old), etc.. I am not sure you can say it's good for you if professionals do it... maybe good for short term performance, but not "good for you." It's actually easier to get protein if you like legumes (including tofu and peas, not sure if these are technical legumes), gluten, and/or nuts. All of these have amazing nutrients, are really cheap, and easy to digest for most people. If they aren't for you that's ok - some people can't digest meat either. Not saying you don't need to take some supplements as a vegan. You probably do, at least b12 and maybe omegas, but you're getting those from "supplements" anyway from meat (it is just fed to the animals first).
