When Is there a need for extra dietary protein?
SOURCES OF PROTEIN SUPPLEMENTS
Liver and Brewers Yeast were the first protein supplements. Then Milk, Whey, and Soy became dominate. Whey quickly gained superior status. Soy protein issues became controversial, and lately as animal disease issues rose up, plant proteins gained popularity.

notes
some body builders exhibited Liver and Kidney damages
bone loss was found to increase
onsuming animal forms of extra protein might have increased pH into the acid range for those without enough dietary alkaline minerals to balance.
increase the need for body processes to withdraw these minerals out of bones.
Plant source proteins put less stress on pH change than animal sources. Another reason to eat vegetables.
Also unknown until recently, a high protein diet, more so from animal than plant protein sources, can upset the intestinal tract microbial balance and tip it toward undesirable bacterial types. Again this might be from a pH or acid alkaline balance modification. Animal protein sources contain sulfur, an acid producing mineral, while plant protein sources do not. Animal sources of proteins were mainly used since they contain the complete amino acid profile while plant sources do not. Mixing two or three plant sources together gets closer to complete. Plant proteins are low in the sulfur containing amino acids, the building blocks of protein.
