Glutamic Acid belongs in the same amino acid family as the highly spoken and popular amino acid Glutamine. An optimal supply of glutamine/glutamic acid is crucial in supporting an active lifestyle, specifically in relation to aerobic exercise. The amino acid has been proven to fuel healthy brain function, improve heart function and protect patients with heart disease and also support the immune system through detoxification.

Heart Function & Protecting Patients with Heart Disease

In the form of monosodium glutamate (MSG), Glutamic Acid has been shown to improve the  heart function and increase the tolerance of exercise in patients with chest pain (stable angina pectoris). It also has the potential to reduce chest pain linked to cases of coronary heart disease.

Neurological & Cognitive Benefits

Glutamic Acid acts as fuel for the brain. It provides a direct energy source which causes the brain to operate and function at a high level. In addition to this, Glutamic acid stimulates mental alertness and improves memory function. It also has a role as an excitatory neurotransmitter within the central nervous system. Glutamic acid influences several areas of the brain including the thalamus, brain stem, spinal cord, basal ganglia and pons. When attached to receptors located in the central nervous system it performs a number of roles one in particular being in the NMDA receptor, where it regulates the number of calcium, magnesium and sodium ions that can leave and enter the cells.

Treatment of Psychological & Mental Conditions

The supplementation of this incredible amino acid has been recommended and used to treat attention deficit disorder (ADD). Medical practitioners believe that glutamic acid will aid in helping young children with behavioural problems by improving concentration and increasing their ability to focus and learn. Glutamic Acid has also had a very important part in the treatment of mood related disorders such as depression, anxiety, schizophrenia, bipolar and many others. It is also known that Glutamic Acid is important in the synthesis of gamma-aminobutyric acid (GABA). As GABA is considered an inhibitory neurotransmitter, it has a reverse role to Glutamic Acid as it aids in decreasing activity within the central nervous system. This is important as low GABA levels are frequently associated with conditions like neuroticism, and manic states of depression. Without Glutamic Acid synthesising GABA, these conditions can occur.

Immune System & Detoxification

Detoxifying ammonia is another essential role Glutamic Acid has. It does this by bonding to nitrogen and creating glutamine. The conversion of glutamic acid into glutamine is how toxic ammonia is removed from the body naturally. The multi purpose amino acid is also necessary in the synthesis of glutathione, one of the most abundant, present and effective antioxidants in the body. Glutathione is extremely important as it helps to protect cells and boost the immune system.
