Amino acids are zwitterionic at physiological pH.

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that amino acids are zwitterionic at physiological pH?

Yes. Two chemistry references state directly that amino acids exist as zwitterions (dipolar ions) at physiological pH, and a biochemistry textbook says the zwitterionic form predominates near physiological pH.
