Glutamic Acid

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

    History of Glutamic Acid

    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 likewise discovered that glutamic acid, after neutralization with castic soda, developed an entirely brand-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 isolation 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 supplied a huge boost for amino acid production and later on with other germs like E. Coli also. [2]


    In addition to being one of the foundation 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 neurons.

    System 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 appreciable quantities; instead 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 extreme quantities may trigger neuronal damage associated in diseases like amyotrophic lateral sclerosis, lathyrism, and Alzheimer’s disease. Also, the drug phencyclidine (more frequently referred to as PCP) antagonizes glutamate at the NMDA receptor, causing behavior similar to schizophrenia. Glutamate in action is very challenging to study due to its transient nature. [3]

    Foods High in Glutamic Acid

    Glutamic acid, also 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 nervous system of the body. They go on to state that many people do not require glutamic acid supplements due to the fact that a sufficient 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 one of the most plentiful protein sources for vegetarians and vegans. According to, soy protein isolate contains among 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 mentions that poultry is a rich source of glutamic acid. Chicken is likewise an abundant protein source that is low in fat, so it’s a healthy food that is an excellent choice as part of a healthy diet.


    Since eggs are great sources of protein, they are likewise rich in natural glutamic acid. According to, eggs consist of about 10 to 11 grams of glutamic acid per 100 grams portion of eggs. This is equivalent to about two to three eggs, relying on their size.


    Different ranges of seeds include varying amounts of glutamic acid, although they are all reasonably focused compared to low protein food choices. For instance, three ounces of sesame seeds includes 9.3 grams of glutamic acid while 3 ounces of cottonseeds contains 10.2 grams of glutamic acid.


    Much like varying species of seeds, levels of glutamic acid found in cheese varies by type. lists Parmesan cheese as one of the most concentrated ranges at 8 grams of the amino acid per 100 grams of cheese.


    Fish is filled with lean protein therefore is a rich source of natural glutamic acid. An example of one such fish types that can be a nutritious source of glutamate consists of Atlantic cod, which includes 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 occur in nearly every living cell from plants, animals, people and microorganisms. It is the most plentiful amino acid in nature. Numerous food that becomes part of a different and balanced diet has high glutamic acid content which ensures the aromatic taste of numerous dishes. “Glutamic acid is an entirely natural building block 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 often in appreciable amounts, for example in tomatoes and Parmesan. Glutamic acid is for that reason a key component in our daily diet– nevertheless, lots of customers are uninformed that it takes place naturally.”.

    A contrast of amino acid profiles

    Like numerous veggies, meat or dairy products, yeast extract consists of natural glutamic acid, a natural amino acid. Glutamic acid is found in every food, but it naturally takes place in greater concentrations in some food, such as tomatoes, cheese, cured ham, soy sauce and numerous others.

    Two truths end up being extremely clear:

    Firstly, 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 content in tomato paste and in a beef stock cube– the clear leader is developed Parmesan cheese. [5]

    Glutamic Acid Benefits

    Improves Athletic Endurance

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

    Minimizes Post Exercise Pain

    When you raise weights, those load-bearing workouts take a toll on your muscles. That post-workout muscle burn is called delayed start muscle discomfort (or DOMS), and while research is continuous, researchers believe that it’s brought on 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 help ease DOMS by hurrying to the “harmed” muscle website (the muscle group you worked out) and constructing new, leaner, stronger muscle tissue. Take glutamine after a hard workout and you’ll begin to observe enhancements in your muscle gains and overall strength.

    Enhances Brain Function

    Why Do You Need 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 quickly throughout workout. Sources of glutamic acid consist of eggs, dairy, and meat. However, you can include more glutamic acid to your diet plan without compromising your dedication to a plant-based lifestyle. Whether you follow a plant-based diet or simply wish to lower your meat consumption, there are plenty of plant-based sources of glutamic acid including:.

    In general, most food sources of protein have a great supply of glutamic acid. So, if an individual lacked protein, then they would be more likely to be deficient in glutamic acid. Glutamic acid develops into glutamine in the body. Without sufficient glutamic acid, you could 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 major role in the central nerve system. It works as an excitatory neurotransmitter in the main nerve system. This indicates that it helps promote an electrical signal known as an action potential when nerve cells interact with each other. The amino acid assists nerve cells send messages and get details from cells.

    In order to serve as a neurotransmitter, glutamic acid should connect to particular receptors in the central nerve system. After this procedure, it can likewise control calcium, magnesium, and sodium ions in the cells. The amino acid is required for correct cell functioning. It’s thought that glutamic acid can influence other neurotransmitters and has a function to play in mental health and neurophysiological disorders.

    Glutamic acid is utilized to develop protein in the body which is necessary in addition to play an essential function in the central nerve system. The amino acid is involved in lots of processes within the body, therefore it can benefit multiple locations of your health. [7]

    Is glutamic acid the same as glutamine?

    Glutamic acid is not the like glutamine. However, it belongs that makes glutamine what it in fact is.

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

    For that reason, if the mineral ion that attaches 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, however it is discovered in animal protein also. Though the 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 requirement than it is for humans. There are other kinds of glutamic acids that impact the body also.

    What Is the Other Kind Of Glutamic Acid?

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

    This type of glutamic acid might have unidentifiable residential or commercial properties that cancel out 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 numerous supplement companies specify that their product is pure and natural, many times there are unknown active ingredients that make up the supplement. Though MSG still contains comparable residential or commercial properties as glutamic acid, it is not glutamic acid in its purest kind.

    Which Is More Efficient, Glutamine or Glutamic Acid?

    Technically, glutamine is originated from glutamic acid. Therefore in some ways, they need each other to assist the human body. Nevertheless, 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 human body, it is stated to help with liver and kidney problems, alcohol withdrawal, and even swelling within the stomach. A few of the conditions that glutamine assists treat are cancer during chemotherapy, Crohn’s Disease, and ulcerative colitis.

    Though glutamine is viewed as the primary amino acid to play the function of fixing muscles and treating specific conditions, glutamic acid is behind the scenes, making all the best moves for glutamine to work its magic. As glutamine can be straight gotten from natural sources of the human diet plan, glutamic acids are not found in many food products. [8]

    Dangers and Adverse Effects

    The World Health Company has stated that glutamate is non-hazardous when used as an additive in foods. According to Yale Scientific, the FDA and the Food and Farming Company of the United Nations both agree. However, there is some proof that it may have the prospective to be harming to nerve cells and the brain when not processed typically or not present in regular quantities.

    What are signs of high glutamate? Signs that someone may be sensitive to this amino acid consist of burning feelings or tingling of the skin, headaches or migraines, queasiness and digestive upset, and chest pains.

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

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

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

    Some research studies have actually found that excessive accumulation of glutamate in the synaptic cleft has actually been associated with excitotoxicty. Accumulation of this non-essential amino acid is now connected with disturbance of normal 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 might add to a number of mental health conditions. GABA is a relaxing neurotransmitter that can have anti-anxiety results, while glutamate is more revitalizing. An imbalance in these 2 neurotransmitters is thought to be at play in some neurological conditions. [9]

    Quantities and Dosage

    The quantity and frequency of glutamine you take depends upon the reason you are taking it. In general, clinical trials use doses of 5 to 45 grams each day for approximately six weeks without any unfavorable negative effects.

    Researchers approximate we take in about 3 to 6 grams daily in our diet. Since the long-term effects of high glutamine intake are unknown, supplement your dietary consumption with low quantities as advised by item directions. But initially, speak to your medical professional to ensure it’s safe for your health. [10]
