Taking a teaspoon of glutamine in a drink a couple of times a day may help reduce sugar cravings by activating gut neurons that signal to the brain's dopamine pathway.

“Now there has not yet been a large scale clinical trial using glutamine to reduce sugar cravings, but the results of the few studies that I looked at, as well as my understanding of the logic of these neuro circuits, including the neuropod cells, brings us to a conclusion that it makes sense why if there's a population of neurons within our gut, that responds very robustly to the presence of sugar, fatty acids, or amino acids, that the intake of particular amino acids would allow the dopamine pathways that might otherwise be triggered by sugar to be triggered by something like glutamine, which has very few or no calories.”

“And there's an interesting literature around the amino acid, glutamine, in particular supplementing with the amino acid, glutamine, as it relates to sugar cravings, and certainly as it relates to other aspects of the gut, in particular leaky gut.”

“But there are many people who are experimenting with supplementing with glutamine, several grams per day, often even, you know, five grams distributed through three or four different servings throughout the day as a way to blunt their sugar cravings.”

“some people have taken to a teaspoon or so of glut of glutamine in some water or other drink couple times throughout the day as a way to reduce their sugar Cravings”
