Glutamic Acid

Glutamic acid (glutamate) is an amino acid used by the body to build proteins and is needed primarily as brain fuel. Glutamate is the most common excitatory (stimulating) neurotransmitter in the central nervous system. Sources of glutamic acid include high-protein foods, such as meat, poultry, fish, eggs, and dairy products. Some protein-rich plant foods also supply glutamic acid.

What it does

  1. Brain protection: Glutamic acid is able to mop up excess ammonia in the brain and convert it back to glutamine. Ammonia can impair cognitive function and damage brain cells.
  2. Brain booster: Acts as a primary source of fuel for the brain.
  3. Prostate protection: When combined with the amino acids alanine and glycine it is thought to have a protective effect on the prostate gland.

Potential Uses

BPH (benign Prostatic Hyperplasia) Brain protection


Monosodium glutamate (MSG), the form of glutamic acid that is used as a flavour enhancer, has been reported in anecdotal studies to have a number of different adverse effects including headache, fatigue, and depression.

Generally, there are no side effects or contra-indications from using glutamic acid supplements.

Because over stimulation of glutamate receptors is thought to be a possible cause of certain neurological diseases, people with a neurological disease should consult their doctor before supplementing with glutamate.

People with liver or kidney disease should consult their doctor before taking high levels of amino acid or protein supplements.
