Glutamic Acid (Glutamate)

Glutamic acid is a non-essential amino acid that the body uses to build proteins. It can be obtained from eating meat, poultry, fish, eggs, and dairy products.

The fluid produced by the prostate gland contains significant amounts of glutamic acid. This has led scientists to believe that glutamic acid may play a role in the normal functioning of the prostate. One clinical study found that supplementary glutamic acid significantly improved the symptoms of benign prostatic hyperplasia (BPH). There is some evidence to suggest that glutamic acid may have protective effects on heart muscle. Results of one study revealed that intravenous injections of glutamic acid (as monosodium glutamate) increased exercise tolerance and heart function in people with stable angina pectoris. However, whether a similar effect would be seen with oral glutamic acid is uncertain.

As glutamic acid is abundant in common foods supplementation is not necessary unless directed by a physician or nutritionist, who will prescribe a relevant dose.

MAXIMUM SAFE LEVEL: Not established

Glutamic acid is generally free of side effects. People with renal or liver disease should consult their doctor before taking supplementary glutamic acid. People who are hypersensitive to monosodium glutamate (MSG), i.e. those who suffer from ‘Chinese Meal Syndrome’ should not take supplementary glutamic acid as it can exacerbate their symptoms. People with kidney or liver disease should consult their doctor before taking supplementary glutamic acid.
