TIL there are vegan sources of MSG, and that peas, tomatoes, and processed meats have high amounts of glutamate: https://www.webmd.com/diet/high-glutamate-foods

Muscles burn Lactic Acid before they burn glucose.

FWIU LAB Lactic Acid Bacteria use Glutamate to control pH by GABA production.

And GABA, well https://en.m.wikipedia.org/wiki/%CE%93-Aminobutyric_acid :

> [GABA] is the chief inhibitory neurotransmitter in the developmentally mature mammalian central nervous system. Its principal role is reducing neuronal excitability throughout the nervous system.

So, IIUC, when you feed LAB glutamate, you get GABA?
