No, but the main component of monosodium glutamate is sodium glutamate. Excessive intake will cause a series of symptoms such as dizziness, headache, drowsiness and muscle spasm. Some people will be anxious and flustered; Some people with sensitive physique may even feel sore bones and muscles.

Eating too much monosodium glutamate will also lead to an increase in the content of glutamic acid in the blood, which limits the utilization of essential minerals such as calcium, magnesium and copper. In particular, glutamic acid can combine with zinc in blood, and the unusable zinc glutamate is excreted, resulting in zinc deficiency in human body. Zinc is an important nutrient for infants' physical and intellectual development. Therefore, infants and nursing mothers should fast or eat less monosodium glutamate.
