L-Glutamic Acid

L-Glutamic Acid


Products Description

L-Glutamic Acid is a non-essential amino acid. Plenty of L-glutamic acid can be found in meat, eggs, dairy products, chicken and fish. In addition, some plant foods also contain glutamic acid. L-glutamic acid stimulates the brain’s glutamate receptors, it’s GABA precursor, flavor enhancer, improve athletic performance, reduce pain after exercise, promote brain development and the digestive system, As the manufacturer and supplier of l-glutamic acids, our assay is 99% up.
