Glutamic Acid

28 mins read

The history of the first amino acid production go back to 1908 when Dr. K. Ikeda, a chemist in Japan, isolated glutamic acid from kelp, a marine alga, after acid hydrolysis and fractionation. He also found that glutamic acid, after neutralization with castic soda, established a completely brand-new, delicious taste.

This was the birth of the use of monosodium glutamate (MSG) as a flavour-enhancing substance. The breakthrough in the production of MSG was the seclusion of a specific soil-inhabiting gram-positive germs, Corynebacterium glutamicum, by Dr. S. Ukada and Dr. S. Kinoshita in 1957. The effective commercialization of monosodium glutamate (MSG) with this bacterium offered a huge boost for amino acid production and later on with other bacteria like E. Coli as well. [2]


In addition to being one of the building blocks in protein synthesis, it is the most prevalent 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 triggers 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; instead it is converted into L-glutamine, which the brain uses for fuel and protein synthesis. It is conjectured that glutamate is involved in cognitive functions like knowing and memory in the brain, though excessive quantities might cause neuronal damage associated in illness like amyotrophic lateral sclerosis, lathyrism, and Alzheimer’s illness. Likewise, the drug phencyclidine (more commonly called PCP) annoys glutamate at the NMDA receptor, triggering behavior similar to schizophrenia. Glutamate in action is very tough to study due to its transient nature. [3]

Foods High in Glutamic Acid

Glutamic acid, likewise called glutamate, is an amino acid that is utilized by the body to develop proteins. According to the University of California San Diego, glutamate is the most common stimulating neurotransmitter in the main nerve system of the body. They go on to state that most people do not require glutamic acid supplementation since an appropriate amount of the amino acid can be discovered in high protein foods like fish, dairy, eggs and meat.

Soy Protein Separate

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


The University of California sandiego specifies that poultry is an abundant source of glutamic acid. Chicken is also an abundant protein source that is low in fat, so it’s a nutritious food that is a good option as part of a healthy diet plan.


Due to the fact that eggs are excellent sources of protein, they are likewise rich in all-natural glutamic acid. According to, eggs consist of about 10 to 11 grams of glutamic acid per 100 grams part of eggs. This is equivalent to about 2 to 3 eggs, relying on their size.


Various ranges of seeds contain varying amounts of glutamic acid, although they are all fairly focused compared to low protein food options. For example, three ounces of sesame seeds consists of 9.3 grams of glutamic acid while 3 ounces of cottonseeds includes 10.2 grams of glutamic acid.


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


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

Natural glutamic acid

Glutamic acid is among the twenty natural amino acids which take place in almost every living cell from plants, animals, humans and bacteria. It is the most plentiful amino acid in nature. Numerous food that belongs to a diverse and well balanced diet has high glutamic acid material which ensures the fragrant 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 found in all protein-rich food sources– for instance in meat, fish and even in pulses. Glutamic acid is formed naturally through the enzymatic ripening procedure in food and in some cases in appreciable amounts, for example in tomatoes and Parmesan. Glutamic acid is for that reason a crucial element in our everyday diet– nevertheless, numerous customers are uninformed that it takes place naturally.”.

A comparison of amino acid profiles

Like numerous vegetables, meat or dairy products, yeast extract consists of natural glutamic acid, a natural amino acid. Glutamic acid is discovered in every food, but it naturally happens in greater concentrations in some food, such as tomatoes, cheese, treated ham, soy sauce and many others.

2 realities end up being extremely clear:

To start with, the glutamic acid is only one of numerous other natural amino acids that take place in our food.

Second of all, the material of the amino acid glutamic acid in the yeast extract paste is comparable with the material in tomato paste and in a beef stock cube– the clear leader is grown Parmesan cheese. [5]

Glutamic Acid Advantages

Improves Athletic Stamina

Glutamic acid might assist improve your endurance when you hit the fitness center by improving the activity of the mitochondria– the part of the cell responsible for giving you major energy.

As males age, it prevails for the prostate glands to start to increase in size. The medical name for this condition is prostatic hyperplasia (BPH). About half of all guys ages 51 to 60 have BPH and up to 90% of males over the age of 80 have it. Experts often suggest glutamic acid supplements for prostate health to reduce signs of BPH.

Detox the Body

Glutamic acid is among the few nutrients that can pass the blood-brain barrier. The amino acid is known for its capability to detoxify cells. In particular, its result on ammonia. During intense exercise, levels of ammonia in the muscle cells increase. This can decrease muscle healing. The amino acid bonds to nitrogen and turns into glutamine. It’s this process that gets rid of the toxic waste and cleanses ammonia from the body.

Try to eat fresh, entire foods like ginger, bananas, lentils, chia seeds, and coconut oil to support your stomach and gastrointestinal 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 used up quickly during workout. Sources of glutamic acid include eggs, dairy, and meat. But, you can include more glutamic acid to your diet without sacrificing your commitment to a plant-based way of life. Whether you follow a plant-based diet or simply want to cut down your meat intake, there are lots of plant-based sources of glutamic acid consisting of:.

In general, many food sources of protein have a good supply of glutamic acid. So, if a person lacked protein, then they would be most likely to be deficient in glutamic acid. Glutamic acid becomes glutamine in the body. Without sufficient glutamic acid, you might develop low levels of glutamine. A glutamine shortage is thought to cause signs like sleeping disorders, low energy, and psychological fatigue.

What is the Role of Glutamic Acid in the Body?

Glutamic acid plays a significant role in the main nerve system. It works as an excitatory neurotransmitter in the main nerve system. This indicates that it helps promote an electrical signal referred to as an action capacity when neurons 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 should connect to particular receptors in the central nervous system. After this procedure, it can likewise regulate calcium, magnesium, and sodium ions in the cells. The amino acid is essential for proper cell functioning. It’s thought that glutamic acid can influence other neurotransmitters and has a function to play in psychological health and neurophysiological conditions.

Glutamic acid is utilized to build protein in the body which is essential as well as play a crucial role in the central nerve system. The amino acid is associated with lots of processes within the body, for that reason it can benefit numerous locations of your health. [7]

Is glutamic acid the same as glutamine?

Glutamic acid is not the same as glutamine. Nevertheless, it is a component that makes glutamine what it really is.

Glutamic acid is an amino acid that is among the complimentary type glutamine within the foundation of protein. Glutamine is stemmed from glutamic acid; it is glutamic acid that is connected to a mineral ion.

Therefore, if the mineral ion that connects to the glutamic acid is potassium, the glutamic acid is then known as potassium glutamate. Not just is glutamic acid discovered in human protein, but it is found in animal protein too. Though the body can produce glutamic acid naturally, it can still be taken as a supplement if a person is doing not have glutamine in their blood.

Glutamic acid in animals is more of a necessity than it is for people. There are other types of glutamic acids that affect the human body too.

What Is the Other Kind Of Glutamic Acid?

The other kind 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 homes that counteract the pure form of the amino acids. This kind of glutamic acid resembles the supplements that professional athletes may use to boost their efficiency.

Though lots of supplement companies mention that their product is pure and natural, many times there are unknown ingredients that comprise the supplement. Though MSG still contains similar properties as glutamic acid, it is not glutamic acid in its purest type.

Which Is More Reliable, Glutamine or Glutamic Acid?

Technically, glutamine is originated from glutamic acid. Therefore in some ways, they require each other to help the body. However, if glutamine is taken as a supplement and not naturally produced within the body, it can be shown to be more effective.

Though glutamine is a non-essential amino acid within the human body, it is stated to assist with liver and kidney issues, alcohol withdrawal, and even inflammation within the stomach. Some of the conditions that glutamine assists deal with are cancer throughout chemotherapy, Crohn’s Disease, and ulcerative colitis.

Though glutamine is viewed as the main amino acid to play the function of repairing muscles and treating particular conditions, glutamic acid is behind the scenes, making all the ideal moves for glutamine to work its magic. As glutamine can be directly gotten from natural sources of the human diet, glutamic acids are not discovered in lots of food items. [8]

Risks and Side Effects

The World Health Organization has actually mentioned that glutamate is non-hazardous when used as an additive in foods. According to Yale Scientific, the FDA and the Food and Agriculture Company of the United Nations both concur. However, there is some proof that it may have the potential to be damaging to nerve cells and the brain when not processed normally or not present in regular quantities.

What are symptoms of high glutamate? Indications that someone might be sensitive to this amino acid consist of burning sensations or tingling of the skin, headaches or migraines, nausea and indigestion, and chest discomforts.

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

Some research suggests that kids with autism spectrum disorder and ADHD may be more sensitive to the results of glutamate, although this is still up for argument.

What causes glutamate excitotoxicity? Excitotoxicity describes the pathological process by which neurons are damaged and killed by the overactivations of receptors, such as the NMDA receptor and AMPA receptor.

Some studies have found that excessive accumulation of glutamate in the synaptic cleft has actually been connected with excitotoxicty. Build-up of this non-essential amino acid is now connected with disturbance of normal transportation systems and uptake systems in the brain, causing 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 calming neurotransmitter that can have anti-anxiety impacts, while glutamate is more stimulating. An imbalance in these two neurotransmitters is presumed to be at play in some neurological conditions. [9]

Amounts and Dose

The amount and frequency of glutamine you take depends on the reason you are taking it. In general, medical trials use doses of 5 to 45 grams daily for as much as 6 weeks with no negative effects.

Researchers estimate we take in about 3 to 6 grams daily in our diet. Since the long-lasting effects of high glutamine consumption are unidentified, supplement your dietary consumption with low quantities as recommended by item directions. However initially, speak with your physician to make sure it’s safe for your health. [10]
