Glutamic Acid

The history of the very 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 discovered that glutamic acid, after neutralization with castic soda, developed an entirely new, delicious taste.

This was the birth of using monosodium glutamate (MSG) as a flavour-enhancing compound. The development 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 successful commercialization of monosodium glutamate (MSG) with this germs provided a big boost for amino acid production and later with other bacteria like E. Coli too. [2]


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

System 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 involved in cognitive functions like knowing and memory in the brain, though extreme amounts might trigger neuronal damage associated in illness like amyotrophic lateral sclerosis, lathyrism, and Alzheimer’s disease. Likewise, the drug phencyclidine (more commonly known as PCP) annoys glutamate at the NMDA receptor, causing habits reminiscent of schizophrenia. Glutamate in action is very difficult to study due to its short-term nature. [3]

Foods High in Glutamic Acid

Glutamic acid, likewise known as glutamate, is an amino acid that is used by the body to build proteins. According to the University of California San Diego, glutamate is the most common stimulating neurotransmitter in the central nerve system of the body. They go on to state that many people do not require glutamic acid supplementation because an adequate amount of the amino acid can be found in high protein foods like fish, dairy, eggs and meat.

Soy Protein Separate

Soy protein isolate is derived from soybeans, and it is among the most abundant protein sources for vegetarians and vegans. According to, soy protein isolate contains one of the greatest 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 states that poultry is an abundant source of glutamic acid. Chicken is also a rich protein source that is low in fat, so it’s a nutritious food that is an excellent option as part of a well-balanced diet.


Since eggs are good 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 include differing amounts of glutamic acid, although they are all relatively focused compared to low protein food choices. For instance, 3 ounces of sesame seeds contains 9.3 grams of glutamic acid while 3 ounces of cottonseeds contains 10.2 grams of glutamic acid.


Similar to varying species of seeds, levels of glutamic acid found in cheese varies 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 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 one of the twenty natural amino acids which happen in nearly every living cell from plants, animals, human beings and bacteria. It is the most plentiful amino acid in nature. Lots of food that belongs to a different and balanced diet has high glutamic acid material which ensures the fragrant taste of many dishes. “Glutamic acid is an entirely natural building block of proteins”, describes Prof. Dr. Rer. Nat. Ursula Bordewick-Dell of the University of Applied Sciences Munster. “It is discovered 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 therefore a key component in our day-to-day diet plan– however, lots of consumers are uninformed that it occurs naturally.”.

A contrast of amino acid profiles

Like numerous vegetables, meat or dairy items, yeast extract includes natural glutamic acid, a natural amino acid. Glutamic acid is found in every food, but it naturally takes place in higher concentrations in some food, such as tomatoes, cheese, cured ham, soy sauce and many others.

Two facts end up being very clear:

Firstly, the glutamic acid is only one of many 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 similar with the content in tomato paste and in a beef stock cube– the clear leader is matured Parmesan cheese. [5]

Glutamic Acid Advantages

Improves Athletic Endurance

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

Decreases Post Exercise Discomfort

When you lift weights, those load-bearing exercises take a toll on your muscles. That post-workout muscle burn is called postponed onset muscle discomfort (or DOMS), and while research study is continuous, researchers think that it’s brought on by tiny tears in your muscle tissue that establish when you lift weights, in addition to an accumulation of lactic acid.

As a protein-building amino acid, glutamic acid can help alleviate DOMS by hurrying to the “damaged” muscle site (the muscle group you worked out) and building new, leaner, stronger muscle tissue. Take glutamine after a tough workout and you’ll begin to observe enhancements in your muscle gains and total strength.

Improves Brain Function

Glutamic acid does not simply reinforce your body; it also enhances your mind. It is among the most crucial neurotransmitters– messengers that send out crucial info to and from your brain.

Without glutamic acid, your brain can’t form memories, and low levels of glutamic acid make it hard to learn and process new details.

Low glutamate levels are often discovered in Alzheimer’s clients and in those with psychiatric disorders like schizophrenia and seizure disorders like epilepsy. It plays a crucial role in brain development in kids, and maintains optimum cognitive function.

Advantages Digestive Health

If you experience irritable bowel syndrome (IBS) or other digestion problems, try taking a day-to-day l-glutamic acid supplement. Studies reveal it promotes healthy digestion by stimulating nutrient absorption, keeping a healthy gut lining, and enhancing the digestive tract concentration of serotonin– another vital neurotransmitter that plays a role in cravings, sleep, and sensations of calmness and wellness. [6]

Enhance Memory and Focus

Glutamic acid works as a fuel for the brain. As you can envision, it has a number of advantages on your brain. Besides being fuel for the brain, this amino acid helps to stimulate focus and enhance memory.

Boost the Body Immune System

Your body utilizes glutamic acid to produce glutathione. Glutathione is an effective antioxidant discovered in the body’s cells and supports the body immune system. The immune system needs a delicate balance of glutathione to function efficiently. Glutathione is especially essential for fighting complimentary radicals, safeguarding cells, and supporting the body immune system.

Assistance Prostate Health

Glutamic acid plays a key function in various locations of the body, including the prostate. The amino acid is vital for proper working in the prostate. As guys age, it’s common 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 approximately 90% of males over the age of 80 have it. Experts typically suggest glutamic acid supplements for prostate health to minimize 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 ability to cleanse cells. In particular, its effect on ammonia. During extreme 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 gets rid of the toxic waste and cleanses ammonia from the body.

Advantage Digestive Health

Glutamic acid may benefit your gastrointestinal health in a number of methods. Research studies show that glutamic acid supports a healthy digestive system by encouraging nutrition absorption and preserving a healthy gut lining. It likewise appears to optimize the concentration of serotonin in the intestinal tract. Serotonin is an essential neurotransmitter that’s essential for your sleep, hunger, and feeling calm.

Your gut and digestion health play a huge part in your total health. Foods like processed meats and unhealthy food can have a negative impact on your gut and impede your digestive system. Try to eat fresh, whole foods like ginger, bananas, lentils, chia seeds, and coconut oil to support your stomach and digestion health.

Why Do You Required Glutamic Acid?

Although your body does produce glutamic acid on its own, many people choose to consume supplements and foods with glutamic acid as it can get consumed quickly during exercise. Sources of glutamic acid consist of eggs, dairy, and meat. But, you can include more glutamic acid to your diet plan without sacrificing your commitment to a plant-based lifestyle. Whether you follow a plant-based diet or just wish to cut down your meat consumption, there are lots of plant-based sources of glutamic acid including:.

In general, the majority of food sources of protein have a good supply of glutamic acid. So, if an individual was deficient in protein, then they would be most likely to be deficient in glutamic acid. Glutamic acid develops into glutamine in the body. Without enough glutamic acid, you might develop low levels of glutamine. A glutamine shortage is thought to cause symptoms like insomnia, low energy, and psychological exhaustion.

What is the Function of Glutamic Acid in the Body?

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

In order to serve as a neurotransmitter, glutamic acid needs to connect to specific receptors in the central nerve system. After this process, it can also regulate calcium, magnesium, and sodium ions in the cells. The amino acid is necessary 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 used to develop protein in the body which is vital as well as play an essential role in the central nerve system. The amino acid is associated with many processes within the body, for that reason it can benefit numerous locations of your health. [7]

Is glutamic acid the like glutamine?

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

Glutamic acid is an amino acid that is among the totally free form glutamine within the building blocks of protein. Glutamine is stemmed from glutamic acid; it is glutamic acid that is connected to a mineral ion.

For that reason, 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 discovered in animal protein as well. Though the human 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 necessity than it is for human beings. There are other kinds of glutamic acids that impact the human body too.

What Is the Other Kind Of Glutamic Acid?

The other sort of glutamic acid is called MSG, which is a kind of glutamic acid that is produced outside of 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 residential or commercial properties that counteract the pure type of the amino acids. This type of glutamic acid is similar to the supplements that professional athletes might use to increase their performance.

Though numerous supplement business state that their product is pure and natural, often times there are unknown components that make up the supplement. Though MSG still consists of similar homes as glutamic acid, it is not glutamic acid in its purest type.

Which Is More Effective, Glutamine or Glutamic Acid?

Technically, glutamine is originated from glutamic acid. For that reason in some ways, they need 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 shown 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. A few of the conditions that glutamine helps deal with are cancer during chemotherapy, Crohn’s Illness, and ulcerative colitis.

Though glutamine is seen as the main amino acid to play the function of fixing muscles and treating certain conditions, glutamic acid is behind the scenes, making all the right moves for glutamine to work its magic. As glutamine can be directly gotten from natural sources of the human diet, glutamic acids are not found in many food items. [8]

Dangers and Side Effects

The World Health Organization 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 Agriculture Organization of the United Nations both agree. Nevertheless, there is some evidence that it might have the potential to be harming to nerve cells and the brain when not processed usually or not present in normal amounts.

What are signs of high glutamate? Indications that somebody might be sensitive to this amino acid include burning sensations or tingling of the skin, headaches or migraines, queasiness and indigestion, and chest discomforts.

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

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

What causes glutamate excitotoxicity? Excitotoxicity describes the pathological procedure by which neurons 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 related to excitotoxicty. Accumulation of this non-essential amino acid is now related to interruption of regular transport systems and uptake mechanisms 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 number of mental health conditions. GABA is a calming neurotransmitter that can have anti-anxiety impacts, while glutamate is more stimulating. An imbalance in these 2 neurotransmitters is presumed to be at play in some neurological conditions. [9]

Amounts and Dosage

The amount and frequency of glutamine you take depends upon the reason you are taking it. In general, clinical trials utilize dosages of 5 to 45 grams daily for up to 6 weeks with no negative effects.

Researchers approximate we take in about 3 to 6 grams daily in our diet plan. Due to the fact that the long-lasting effects of high glutamine consumption are unknown, supplement your dietary intake with low quantities as suggested by product directions. But initially, speak to your doctor to make sure it’s safe for your health. [10]
