Consuming beef brain supplement may be beneficial for humans due to evolutionary access to brain nutrients like DHA.

“I definitely take their beef brain supplement when I don't have a real brain which is pretty rare and I'm really curious what it could be doing for all of you I think it probably is beneficial for all of us humans to be eating more nose-to-tail and getting this brain and I think that if we think evolutionarily speaking the brain was probably one of the most important things that we were eating as humans we probably had access to the brain and the way that very few other animals did and the nutrients in that brain like DHA were uniquely beneficial for humans”
