L-Glutamine - the most abundant amino acid in the human body - is involved in many metabolic processes, including the synthesis and protection of muscle tissue, the production of glycogen and immune support during periods of immune and muscular stress. L-Glutamine is also a major source of fuel for enterocytes (intestinal cells) and hence supports the integrity of the intestinal lining.

Suggested Use

Mix 1/2 teaspoon (approximately 2 grams) into 6 to 8 oz of fluid and drink when stomach is empty or as directed by your qualified healthcare professional. For athletes, maximal results will be obtained by supplementing with 2 grams of glutamine after exercise.

This stuff is a GOD SEND for IBS/LGS
Long story short: lifelong stress created a gurgly and full-of-holes gut. My digestion was a mess, I'd have itching spells every morning before eliminating (for YEARS), I am allergic to just about all foods, etc. Really bad case of IBS/LGS for past 3 years. After a WEEK I could already tell something good was happening. I'm only on a solid month of this so far and I was able to convince my stubborn dad to start taking this as well. It says a LOT that he, too, feel his product is changing his gut and overall health for the better even after 1 week. Do research on L-Glutamine and see for yourself the miraculous benefits this stuff gives a body. It's simply a God send. My regret is that I didn't know about this 25 years ago to start the healing process before it got as bad as it did and did the damage it did. Update: Using this product and Jarrow's probiotics, I am LOSING WEIGHT and able to eat a nice big portion of food every day! I used to eat a handful of bites and immediately feel full and completely bloated. I KNEW I shouldn't be overweight at all with what I was eating. i was right. This has changed a lifelong issue. I can only pray it stays this way and doesn't somehow mobilize and stop working. but so far, amazingly great.

Love Glutamine...
I suffer from LGS and have for several years. Glutamine has been a god-send. Since I started taking this product, my LGS has reversed and I rarely, if ever, suffer any symptoms. I take 3 heaping teaspoons a day with water on an empty stomach. Tastes great, no after taste. Love, love, love this product.
