Glutamic acid is a nonessential amino acid that the body uses to build proteins. Although glutamine and glutamic acid have similar names, they are structurally different. The fluid produced by the prostate gland contains significant amounts of glutamic acid, and this amino acid may play a role in normal function of the prostate. In one study, symptoms of benign prostatic hyperplasia were improved in a group of forty-five men taking 780 mg of glutamic acid per day for two weeks and then 390 mg for the next two and a half months in combination with equal amounts of the amino acids alanine and glycine. Where is it found? As with the other amino acids, excellent sources of glutamic acid include meat, poultry, fish, eggs, and dairy products. Some protein-rich plant foods also supply glutamic acid.

In what conditions might glutamic acid be supportive?
