I think 40 -50 years from now we will look back and realize we were guinea pigs for the next couple of generation.

Hi! I have some information about L-Glutamine which I want to share with all of you.

L-Glutamine is energy sources utilized by rapidly proliferating cells. Glutamic acid the most abundant amino group in the human brain. L-Glutamine and Glutamine Powder plays a vital role to building and maintenance of muscle tissue.

I hope this information will be useful for you.

OP: You probably mean straight L-Glutamine, not what comes as a fraction in whey protein, etc. Yes, I add a heaping teaspoon to each of the two bottles of 6% carbo solution I drink the day before a special ride, thinking it helps a bit with recovery and such like. Don't know if it works, but I have good rides when I do it, and it sure is cheap. When I'm going to be extra ruined, I'll also add some to my homemade recovery drink, on the advice of a CTS coach. I also add 5g creatine to my recovery drink, on same advice, since I'm a vegetarian. I am not a double-blind trial.

Please check the posting dates before responding. This thread died 4 years ago.

If you've got something to say about glutamine, better to start a new thread than respond to one that old.

And your link is bogus - it's to a site that sells supplements.


FWIW, I use L-Glutamine in my recovery drinks...it seems to help my legs feel a bit fresher the day after a hard workout. I get mine at Wal-Mart (around $10 for 300 grams - less than half the cost of the price on that website).

I just need to add something to this discussion since it seems to be brought back to life-

I'm not sure about the scientific proof, but I know when I used to work out heavily in the gym I used to be sore at least 3 times a week. After I started taking straight glutamine in powder form added to my protein shakes, I just never got sore again. It was like night and day. I'm not trying to sell you anything, nor do I know anything about special brands, but I can plain out vanilla tell you that it worked for me. It's also something I've been meaning to get my hands on again, think I will soon (but oh the price tag..)

Glutamine is cheap...just don't buy it at over-priced places like GNC.

You can buy a 300 gram tub at Wal-Mart for $9.95, or 1000 grams for $27.99 at vitacost.com.

Oh, and yes...the stuff does work. I usually have 5-10 grams with my post-ride or evening protein shake, and find that it helps my legs feel fresher the next day.

FWIW I use it during the riding season. I use to have awfull cramps at night and twitching all the time. Yes I drink a ton of water, use all the nutrition stuff, IE hammer gels, perpetuem, recovorite, etc. and still had problems. A giy I ride with recommended L-Glutamine and hey all my troubles went away. By no means scintific but it worked for me.

Acute L-glutamine ingestion does not improve maximal effort exercise.
Haub MD, Potteiger JA, Nau KL, Webster MJ, Zebas CJ. Journal of Sports Medicine and Physical Fitness. Turin: Sep 1998. Vol. 38, Iss. 3; pg. 240
Abstract (Summary)

BACKGROUND: L-glutamine (GLN) may have an ergogenic effect during exercise considering its base generating potential. We attempted to determine whether GLN ingestion influences acid-base balance and improves high intensity exercise performance. METHOD: Ten trained males performed five exercise bouts on a cycle ergometer at 100% of VO2 peak. The first four bouts were 60 sec in duration, while the fifth bout was continued to fatigue. Each bout was separated by 60 sec of recovery. The exercise bouts were initiated 90 min after ingesting 0.03 g.kg body mass-1 of either GLN or placebo (PLC). Venous blood samples were collected pre-ingestion (PRE-IN), pre-exercise (PRE-EX), and following bouts four (B4) and five (B5) and analyzed for pH, bicarbonate concentration (HCO3), and lactate concentration (La-). Time to fatigue for B5 was used as a performance measure. RESULTS: pH, [HCO3], and [La-] were not significantly different (p > 0.05) between conditions for PRE-IN, PRE-EX, B4, and B5. Time to fatigue was not significantly different between conditions and averaged 263.4 +/- 24.5 sec and 263.2 +/- 19.4 sec for the GLN and PLC trials, respectively. CONCLUSIONS: These data indicate that acute ingestion of L-glutamine does not enhance either buffering potential or high intensity exercise performance in trained males.


Therapeutic considerations of L-glutamine: a review of the literature.
Authors: Miller AL

The most abundant amino acid in the bloodstream, L-glutamine fulfills a number of biochemical needs. It operates as a nitrogen shuttle, taking up excess ammonia and forming urea. It can contribute to the production of other amino acids, glucose, nucleotides, protein, and glutathione. Glutamine is primarily formed and stored in skeletal muscle and lungs, and is the principal metabolic fuel for small intestine enterocytes, lymphocytes, macrophages, and fibroblasts. Supplemental use of glutamine, either in oral, enteral, or parenteral form, increases intestinal villous height, stimulates gut mucosal cellular proliferation, and maintains mucosal integrity. It also prevents intestinal hyperpermeability and bacterial translocation, which may be involved in sepsis and the development of multiple organ failure. L-glutamine use has been found to be of great importance in the treatment of trauma and surgery patients, and has been shown to decrease the incidence of infection in these patients. Cancer patients often develop muscle glutamine depletion, due to uptake by tumors and chronic protein catabolism. Glutamine may be helpful in offsetting this depletion; however, it may also stimulate the growth of some tumors. The use of glutamine with cancer chemotherapy and radiotherapy seems to prevent gut and oral toxic side-effects, and may even increase the effectiveness of some chemotherapy drugs.

Ok so we can finally conclude that l-glutamine helps recovery yet does not help during physical exertion. Makes sense. I'm good with that, I think this thread can be laid to rest again. For recovery though, there's nothing better IMO.

Glutamine does NOT increase muscle size, nor does it increase muscle volume... Glutamine has only been shown to help increase the effectiveness of the immune system, help preserve lean mass, and can help assist with the recovery portion of the workout as it helps create a positive nitrogen balance within the body. Glutamine can also enter the Krebs Cycle as a non-carbohydrate source and form more ATP, but thats only during times of stravation

Nothing beats low-glycemic carbohydrates pre-workout and high-glycemic carbohydrates post-workout...

Try looking into waxy maize startch as part of your post-workout meal combined with whey protein 30 minutes after your workout with a carb/protein ratio of 3:1... I promise you'll have a energy to push harder the next day

l-glutamine can be found in whey protein shakes. Ratio of 80% casein and 20% whey works best. A brand called muscle milk uses that combination, you can buy them seperately from Optimal Nutrition if you want higher grade stuff and mix it yourself
