Some protein powder barrels will have a list of amino acids with a glutamic acid in it. Is the content of glutamic acid.
You can also search for glutamine, and it will tell you that glutamic acid and other amino acids will synthesize glutamine.
And the protein powder you eat, the eggs you eat, the meat you eat, as long as it is protein food. After being decomposed into various amino acids in the body, some of them can be transformed by themselves, including BCAA. He just needs some time.
Why don't you just take it quickly?
One more thing, glutamine will also be added to the protein powder. Some protein powders, if you look at the powder carefully in a well-lit place, will have small white crystals inside. Small particles such as monosodium glutamate are said to be glutamine (but I'm not sure about this)
Generally speaking, if the economic conditions are excellent, glutamine, BCAA. Can be eaten.
