About super seasoning
Monosodium glutamate (MSG) is a white crystalline powder that resembles table salt or sugar. MSG is derived from the amino acid glutamate, or glutamic acid, which is one of the most abundant amino acids in nature. It combines sodium and glutamic acid, known as a sodium salt. The glutamic acid in MSG is made by fermenting starches and its taste is called umami- one of the five tastes known as salty, sour, bitter, sweet and umami. MSG is a flavor enhancer, food additives, commonly added in foods, canned vegetables, soups and processed meats.
MSG symptoms for over intake (Daily intake <1g)
- Facial pressure or tightness
- Numbness, tingling or burning in the face, neck and other areas
- Rapid, fluttering heartbeats (heart palpitations)
- Chest pain
- Feel full stomach
Researchers acknowledged that a small percentage of people may have short-term reactions to MSG. Symptoms are usually mild and don’t require treatment.
Glutamic acid functions as an excitatory neurotransmitter, meaning that it stimulates nerve cells in order to relay the signal of the brain. Some people claim that MSG leads to excessive glutamate in the brain and excessive stimulation of nerve cells. For this reason, MSG has been labeled an excitotoxin.
Some people may experience adverse effects from consuming MSG. This condition is called Chinese restaurant syndrome or MSG symptom complex. MSG’s umami flavor may stimulate receptors found on your tongue and in your digestive tract, triggering the release of appetite-regulating hormones. While some studies suggest that MSG may reduce your calorie intake, others claim that it boosts intake.

Where does MSG go?
Ingested MSG has been found to be safe, and to produce no remarkable effects, except on taste. Hence, almost no ingested MSG passes from gut into blood, and essentially none transits placenta from maternal to fetal circulation, or crosses the blood-brain barrier. First, glutamate is transported from intestine to lumen across the apical membrane. It is then metabolized to carbon dioxide by entering the tricarboxylic acid cycle.
But it is not good for health since it is extensively oxidized in gut and intestine.
