It may also help in the healing of ulcers. This seaweed extract, now commonly produced chemically, may suggest the possible toxicity of glutamic acid as slightly neurologically irritating in high dosages. Otherwise, glutamine is relatively safe and is the best way to supplement this amino acid.

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 the normal function of the prostate. 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. Glutamic acid is remarkably free of side effects for the vast majority of people who take it, although individuals with kidney or liver disease should not consume high intakes of amino acids without consulting a health care professional.
