Glutamic Acid

28 mins read

The history of the very first amino acid production dates back to 1908 when Dr. K. Ikeda, a chemist in Japan, separated glutamic acid from kelp, a marine alga, after acid hydrolysis and fractionation. He also discovered that glutamic acid, after neutralization with castic soda, established an entirely new, scrumptious taste.

This was the birth of using monosodium glutamate (MSG) as a flavour-enhancing substance. The development in the production of MSG was the seclusion of a particular soil-inhabiting gram-positive bacterium, Corynebacterium glutamicum, by Dr. S. Ukada and Dr. S. Kinoshita in 1957. The successful commercialization of monosodium glutamate (MSG) with this bacterium provided a huge boost for amino acid production and later with other germs like E. Coli too. [2]


In addition to being among the building blocks in protein synthesis, it is the most widespread neurotransmitter in brain function, as an excitatory neurotransmitter and as a precursor for the synthesis of GABA in gabaergic nerve cells.

Mechanism of action

Glutamate activates both ionotropic and metabotropic glutamate receptors. The ionotropic ones being non-NMDA (AMPA and kainate) and NMDA receptors. Free glutamic acid can not cross the blood-brain barrier in considerable quantities; rather it is converted into L-glutamine, which the brain utilizes for fuel and protein synthesis. It is conjectured that glutamate is involved in cognitive functions like knowing and memory in the brain, though excessive amounts may trigger neuronal damage associated in diseases like amyotrophic lateral sclerosis, lathyrism, and Alzheimer’s illness. Also, the drug phencyclidine (more typically called PCP) antagonizes glutamate at the NMDA receptor, triggering habits similar to schizophrenia. Glutamate in action is extremely tough to study due to its transient nature. [3]

Foods High in Glutamic Acid

Glutamic acid, also known as glutamate, is an amino acid that is used by the body to construct proteins. According to the University of California San Diego, glutamate is the most typical stimulating neurotransmitter in the main nervous system of the body. They go on to state that the majority of people do not require glutamic acid supplements due to the fact that an adequate quantity of the amino acid can be discovered in high protein foods like fish, dairy, eggs and meat.

Soy Protein Isolate

Soy protein isolate is derived from soybeans, and it is among the most plentiful protein sources for vegetarians and vegans. According to, soy protein isolate includes among the highest concentrations of glutamic acid when compared to other high protein foods. For every 100 grams of soy protein, there is 17 grams of glutamic acid.


The University of California sandiego mentions that poultry is an abundant source of glutamic acid. Chicken is likewise a rich protein source that is low in fat, so it’s a nutritious food that is an excellent choice as part of a healthy diet.


Due to the fact that eggs are great sources of protein, they are likewise abundant in natural glutamic acid. According to, eggs include about 10 to 11 grams of glutamic acid per 100 grams part of eggs. This is equivalent to about two to three eggs, depending upon their size.


Various varieties of seeds contain differing amounts of glutamic acid, although they are all reasonably concentrated compared to low protein food options. For instance, 3 ounces of sesame seeds contains 9.3 grams of glutamic acid while 3 ounces of cottonseeds includes 10.2 grams of glutamic acid.


Just like differing types of seeds, levels of glutamic acid found in cheese differs by type. notes Parmesan cheese as one of the most focused ranges at 8 grams of the amino acid per 100 grams of cheese.


Fish is filled with lean protein therefore is an abundant source of natural glutamic acid. An example of one such fish types that can be a healthy source of glutamate includes Atlantic cod, which includes about 15 grams of glutamic acid per 6 ounces of portion. [4]

Natural glutamic acid

Glutamic acid is one of the twenty natural amino acids which happen in practically every living cell from plants, animals, people and microorganisms. It is the most abundant amino acid in nature. Lots of food that belongs to a diverse and well balanced diet plan has high glutamic acid content which ensures the aromatic taste of numerous dishes. “Glutamic acid is a completely natural foundation of proteins”, discusses Prof. Dr. Rer. Nat. Ursula Bordewick-Dell of the University of Applied Sciences Munster. “It is discovered in all protein-rich food sources– for instance in meat, fish and even in pulses. Glutamic acid is formed naturally through the enzymatic ripening process in food and sometimes in appreciable amounts, for example in tomatoes and Parmesan. Glutamic acid is for that reason an essential component in our daily diet– however, numerous consumers are unaware that it occurs naturally.”.

A comparison of amino acid profiles

Like many veggies, meat or dairy items, yeast extract contains natural glutamic acid, a natural amino acid. Glutamic acid is found in every food, however it naturally happens in greater concentrations in some food, such as tomatoes, cheese, cured ham, soy sauce and numerous others.

2 realities become extremely clear:

Firstly, the glutamic acid is only one of numerous other natural amino acids that occur in our food.

Secondly, the content of the amino acid glutamic acid in the yeast extract paste is similar with the material in tomato paste and in a beef stock cube– the clear leader is matured Parmesan cheese. [5]

Glutamic Acid Advantages

Enhances Athletic Endurance

Glutamic acid might assist improve your endurance when you struck the health club by increasing the activity of the mitochondria– the part of the cell responsible for providing you major energy.

Decreases Post Exercise Pain

When you lift weights, those load-bearing workouts take a toll on your muscles. That post-workout muscle burn is called delayed onset muscle soreness (or DOMS), and while research is ongoing, researchers believe that it’s caused by tiny tears in your muscle tissue that develop when you lift weights, in addition to a buildup of lactic acid.

As a protein-building amino acid, glutamic acid can assist ease DOMS by hurrying to the “damaged” muscle site (the muscle group you worked out) and developing brand-new, leaner, stronger muscle tissue. Take glutamine after a tough exercise and you’ll start to see enhancements in your muscle gains and total strength.

Increases Brain Function

Without glutamic acid, your brain can’t form memories, and low levels of glutamic acid make it tough to discover and process brand-new details.

Low glutamate levels are often found in Alzheimer’s patients and in those with psychiatric conditions like schizophrenia and seizure conditions like epilepsy. It plays an important function in brain advancement in kids, and maintains optimum cognitive function.

Benefits Digestion Health

If you struggle with irritable bowel syndrome (IBS) or other digestive issues, attempt taking a day-to-day l-glutamic acid supplement. Research studies show it promotes healthy digestion by stimulating nutrient absorption, maintaining a healthy gut lining, and optimizing the digestive tract concentration of serotonin– another vital neurotransmitter that plays a role in hunger, sleep, and feelings of calmness and well-being. [6]

The immune system needs a fragile balance of glutathione to work optimally. Glutathione is especially essential for battling free radicals, protecting cells, and supporting the body immune system.

Support Prostate Health

Glutamic acid plays a crucial role in many different areas of the body, including the prostate. The amino acid is essential for proper operating in the prostate. As guys age, it prevails for the prostate glands to begin to increase in size. The medical name for this condition is prostatic hyperplasia (BPH). About half of all men ages 51 to 60 have BPH and as much as 90% of men over the age of 80 have it. Experts typically recommend glutamic acid supplements for prostate health to minimize symptoms of BPH.

Detox the Body

Glutamic acid is one of the few nutrients that can pass the blood-brain barrier. The amino acid is known for its capability to detoxify cells. In particular, its effect on ammonia. During intense exercise, levels of ammonia in the muscle cells increase. This can slow down muscle recovery. The amino acid bonds to nitrogen and develops into glutamine. It’s this procedure that eliminates the toxic waste and cleanses ammonia from the body.

Benefit Digestive Health

Glutamic acid may benefit your digestive health in a variety of methods. Studies reveal that glutamic acid supports a healthy gastrointestinal system by motivating nutrient absorption and maintaining a healthy gut lining. It also appears to enhance the concentration of serotonin in the intestine. Serotonin is an important neurotransmitter that’s vital for your sleep, hunger, and feeling calm.

Your gut and gastrointestinal health play a big part in your general health. Foods like processed meats and unhealthy food can have a negative influence on your gut and restrain your digestion system. Try to consume fresh, whole foods like ginger, bananas, lentils, chia seeds, and coconut oil to support your stomach and digestive health.

Why Do You Required Glutamic Acid?

Although your body does produce glutamic acid on its own, lots of people pick to take in supplements and foods with glutamic acid as it can get consumed rapidly during workout. Sources of glutamic acid consist of eggs, dairy, and meat. But, you can add more glutamic acid to your diet without compromising your dedication to a plant-based way of life. Whether you follow a plant-based diet or just wish to cut down your meat consumption, there are a lot of plant-based sources of glutamic acid consisting of:.

In general, the majority of food sources of protein have a good supply of glutamic acid. So, if a person was deficient in protein, then they would be more likely to be lacking in glutamic acid. Glutamic acid becomes glutamine in the body. Without adequate glutamic acid, you might develop low levels of glutamine. A glutamine deficiency is believed to trigger signs like insomnia, low energy, and mental fatigue.

What is the Role of Glutamic Acid in the Body?

Glutamic acid plays a major role in the main nervous system. It works as an excitatory neurotransmitter in the central nerve system. This means that it assists promote an electrical signal referred to as an action capacity when nerve cells communicate with each other. The amino acid helps afferent neuron send out messages and get information from cells.

In order to function as a neurotransmitter, glutamic acid needs to attach to particular receptors in the main nerve system. After this process, it can also manage calcium, magnesium, and sodium ions in the cells. The amino acid is necessary for proper cell functioning. It’s believed that glutamic acid can influence other neurotransmitters and has a role to play in psychological health and neurophysiological disorders.

Glutamic acid is utilized to develop protein in the body which is important along with play a key role in the main nerve system. The amino acid is associated with numerous processes within the body, therefore it can benefit several areas of your health. [7]

Is glutamic acid the like glutamine?

Glutamic acid is not the like glutamine. Nevertheless, it belongs that makes glutamine what it actually is.

Glutamic acid is an amino acid that is amongst the free kind glutamine within the building blocks of protein. Glutamine is originated from glutamic acid; it is glutamic acid that is attached to a mineral ion.

Therefore, if the mineral ion that attaches to the glutamic acid is potassium, the glutamic acid is then referred to as potassium glutamate. Not only is glutamic acid discovered in human protein, but it is found in animal protein also. Though the body can produce glutamic acid naturally, it can still be taken as a supplement if a person is lacking glutamine in their blood.

Glutamic acid in animals is more of a requirement than it is for human beings. There are other kinds of glutamic acids that impact the body also.

What Is the Other Type of Glutamic Acid?

The other type of glutamic acid is called MSG, which is a type of glutamic acid that is produced beyond the human or animal body rather than within it. When the glutamic acid is not produced within the body, it is not as pure. Glutamic acid is unprocessed.

This kind of glutamic acid might have unidentifiable properties that cancel out the pure type of the amino acids. This kind of glutamic acid resembles the supplements that athletes might utilize to enhance their performance.

Though many supplement business state that their product is pure and natural, sometimes there are unidentified active ingredients that comprise the supplement. Though MSG still includes comparable homes as glutamic acid, it is not glutamic acid in its purest form.

Which Is More Efficient, Glutamine or Glutamic Acid?

Technically, glutamine is derived from glutamic acid. For that reason in some ways, they require each other to assist the human body. However, if glutamine is taken as a supplement and not naturally produced within the body, it can be revealed to be more efficient.

Though glutamine is a non-essential amino acid within the body, it is said to help with liver and kidney issues, alcohol withdrawal, and even swelling within the stomach. Some of the conditions that glutamine helps deal with are cancer during chemotherapy, Crohn’s Disease, and ulcerative colitis.

Though glutamine is viewed as the main amino acid to play the role of repairing muscles and treating particular conditions, glutamic acid lags the scenes, making all the ideal moves for glutamine to work its magic. As glutamine can be straight gotten from natural sources of the human diet, glutamic acids are not found in numerous food products. [8]

Dangers and Negative Effects

The World Health Company has stated that glutamate is non-hazardous when utilized as an additive in foods. According to Yale Scientific, the FDA and the Food and Agriculture Organization of the United Nations both agree. Nevertheless, there is some proof that it may have the possible to be harming to nerve cells and the brain when not processed typically or not present in typical amounts.

What are symptoms of high glutamate? Indications that someone may be sensitive to this amino acid consist of burning experiences or tingling of the skin, headaches or migraines, queasiness and indigestion, and chest pains.

Does glutamate cause stress and anxiety? It’s possible. There’s evidence from some studies that high levels in the brain may be a contributing element to many psychological health conditions, consisting of stress and anxiety, depression, epilepsy, bipolar illness, migraines, Huntington’s disease, memory loss, multiple sclerosis, ADHD, autism and others.

Some research study recommends that kids with autism spectrum disorder and ADHD might be more conscious the effects of glutamate, although this is still up for dispute.

What triggers glutamate excitotoxicity? Excitotoxicity describes the pathological procedure by which nerve cells are damaged and eliminated by the overactivations of receptors, such as the NMDA receptor and AMPA receptor.

Some research studies have actually discovered that extreme accumulation of glutamate in the synaptic cleft has actually been connected with excitotoxicty. Accumulation of this non-essential amino acid is now related to interruption of typical transport systems and uptake mechanisms in the brain, resulting in neuronal injury, trauma and associated metabolic failures.

High glutamate in proportion to another neurotransmitter called GABA might add to a variety of mental health conditions. GABA is a soothing neurotransmitter that can have anti-anxiety results, while glutamate is more stimulating. An imbalance in these 2 neurotransmitters is presumed to be at play in some neurological conditions. [9]

Quantities and Dosage

The amount and frequency of glutamine you take depends on the factor you are taking it. In general, medical trials utilize doses of 5 to 45 grams each day for as much as 6 weeks without any negative effects.

Researchers estimate we take in about 3 to 6 grams daily in our diet plan. Since the long-lasting impacts of high glutamine consumption are unidentified, supplement your dietary intake with low quantities as recommended by product instructions. But first, talk with your doctor to make sure it’s safe for your health. [10]
