Glutamic Acid

A crystalline amino acid C5H9NO4 commonly distributed in plant and animal proteins. [1]

History of Glutamic Acid

The history of the 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 likewise found that glutamic acid, after neutralization with castic soda, established a completely new, tasty taste.

This was the birth of using monosodium glutamate (MSG) as a flavour-enhancing substance. The advancement in the production of MSG was the seclusion of a particular 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 germs provided a huge increase for amino acid production and later with other bacteria like E. Coli as well. [2]


In addition to being one of the foundation 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 neurons.

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 amounts; rather it is converted into L-glutamine, which the brain uses for fuel and protein synthesis. It is conjectured that glutamate is associated with cognitive functions like learning and memory in the brain, though extreme amounts might cause neuronal damage associated in illness like amyotrophic lateral sclerosis, lathyrism, and Alzheimer’s illness. Likewise, the drug phencyclidine (more frequently known as PCP) antagonizes glutamate at the NMDA receptor, causing behavior reminiscent of schizophrenia. Glutamate in action is incredibly tough to study due to its short-term nature. [3]

Foods High in Glutamic Acid

Glutamic acid, likewise called 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 common 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 a sufficient quantity of the amino acid can be found in high protein foods like fish, dairy, eggs and meat.

Soy Protein Separate

Soy protein isolate is originated from soybeans, and it is among the most abundant protein sources for vegetarians and vegans. According to, soy protein isolate consists of among the highest concentrations of glutamic acid when compared to other high protein foods. For each 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 also an abundant protein source that is low in fat, so it’s a nutritious food that is an excellent choice as part of a healthy diet plan.


Due to the fact that eggs are excellent sources of protein, they are also abundant in natural glutamic acid. According to, eggs contain 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.


Different ranges of seeds include differing quantities of glutamic acid, although they are all fairly focused compared to low protein food options. For example, three ounces of sesame seeds contains 9.3 grams of glutamic acid while 3 ounces of cottonseeds includes 10.2 grams of glutamic acid.


Much like varying species of seeds, levels of glutamic acid discovered 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 and so is an abundant source of natural glutamic acid. An example of one such fish types that can be a nutritious source of glutamate includes Atlantic cod, which consists of about 15 grams of glutamic acid per 6 ounces of part. [4]

Natural glutamic acid

Glutamic acid is one of the twenty natural amino acids which take place in practically every living cell from plants, animals, people and microorganisms. It is the most abundant amino acid in nature. Many food that becomes part of a different and well balanced diet plan has high glutamic acid content which ensures the fragrant taste of many dishes. “Glutamic acid is an entirely natural foundation of proteins”, explains Prof. Dr. Rer. Nat. Ursula Bordewick-Dell of the University of Applied Sciences Munster. “It is found in all protein-rich food sources– for example 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 instance in tomatoes and Parmesan. Glutamic acid is for that reason an essential part in our daily diet– nevertheless, numerous customers are unaware that it happens naturally.”.

A comparison of amino acid profiles

Like lots of veggies, meat or dairy products, yeast extract consists of 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 many others.

2 truths become really clear:

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

Second of all, 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 grown Parmesan cheese. [5]

Glutamic Acid Advantages

Improves Athletic Stamina

Glutamic acid could assist enhance your endurance when you struck the fitness center by increasing the activity of the mitochondria– the part of the cell responsible for offering you significant energy.

Why Do You Required Glutamic Acid?

Although your body does produce glutamic acid on its own, lots of people select to take in supplements and foods with glutamic acid as it can get consumed quickly throughout exercise. Sources of glutamic acid include eggs, dairy, and meat. But, you can add more glutamic acid to your diet without compromising your commitment to a plant-based way of life. Whether you follow a plant-based diet or just want to reduce your meat intake, there are plenty 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 an individual lacked protein, then they would be more likely to be deficient in glutamic acid. Glutamic acid turns into glutamine in the body. Without adequate glutamic acid, you could develop low levels of glutamine. A glutamine shortage is believed to cause symptoms like sleeping disorders, low energy, and mental fatigue.

What is the Function of Glutamic Acid in the Body?

Glutamic acid plays a major function in the main nervous system. It works as an excitatory neurotransmitter in the main nervous system. This implies that it helps promote an electrical signal known as an action potential when nerve cells communicate with each other. The amino acid helps nerve cells send messages and receive information from cells.

In order to function as a neurotransmitter, glutamic acid should connect to specific receptors in the central nervous system. After this process, it can likewise control calcium, magnesium, and sodium ions in the cells. The amino acid is needed for correct cell functioning. It’s thought that glutamic acid can affect 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 along with play a crucial role in the central nerve system. The amino acid is associated with numerous procedures within the body, for that reason it can benefit multiple 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 actually is.

Glutamic acid is an amino acid that is among the complimentary kind glutamine within the foundation of protein. Glutamine is derived 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 referred to as potassium glutamate. Not just is glutamic acid found in human protein, but it is discovered in animal protein too. Though the human body can produce glutamic acid naturally, it can still be taken as a supplement if an individual is doing not have glutamine in their blood.

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

What Is the Other Type of Glutamic Acid?

The other sort of glutamic acid is called MSG, which is a kind 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 may have unidentifiable properties that counteract the pure form of the amino acids. This kind of glutamic acid resembles the supplements that athletes might use to boost their performance.

Though many supplement companies mention that their product is pure and natural, sometimes there are unidentified components that comprise the supplement. Though MSG still contains similar homes as glutamic acid, it is not glutamic acid in its purest form.

Which Is More Efficient, Glutamine or Glutamic Acid?

Technically, glutamine is originated from glutamic acid. For that reason in some ways, they need each other to assist the body. Nevertheless, 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 assist with liver and kidney issues, alcohol withdrawal, and even swelling within the stomach. Some of the conditions that glutamine assists deal with are cancer during chemotherapy, Crohn’s Illness, and ulcerative colitis.

Though glutamine is viewed as the primary amino acid to play the function of fixing muscles and treating certain conditions, glutamic acid lags 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 plan, glutamic acids are not discovered in many food products. [8]

Threats and Side Effects

The World Health Company has actually mentioned that glutamate is non-hazardous when utilized as an additive in foods. According to Yale Scientific, the FDA and the Food and Farming Company of the United Nations both concur. Nevertheless, there is some evidence that it might have the possible to be harming to nerve cells and the brain when not processed usually or not present in normal quantities.

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

Does glutamate cause stress and anxiety? It’s possible. There’s proof from some studies that high levels in the brain might be a contributing factor to numerous psychological health conditions, consisting of anxiety, depression, epilepsy, bipolar disorder, migraines, Huntington’s disease, amnesia, numerous sclerosis, ADHD, autism and others.

Some research recommends that children with autism spectrum condition and ADHD may be more sensitive to the results of glutamate, although this is still up for debate.

What causes 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 excessive accumulation of glutamate in the synaptic cleft has actually been associated with excitotoxicty. Build-up of this non-essential amino acid is now related to disruption of regular transportation systems and uptake systems in the brain, leading to neuronal injury, trauma and associated metabolic failures.

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

Amounts and Dosage

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

Scientists approximate we consume about 3 to 6 grams daily in our diet. Due to the fact that the long-term results of high glutamine intake are unknown, supplement your dietary consumption with low quantities as advised by product instructions. But initially, speak with your physician to make sure it’s safe for your health. [10]
