NSI L-Glutamine Powder 4,500 mg -- 2.2 lbs

NSI L-Glutamine Powder 4,500 mg -- 2.2 lbs

Strengthen and defend yourself against fatigue and muscle tissue breakdown! Our new L-glutamine formulation now in a convenient powder! How Does L-Glutamine Powder Work? Generally, the concentration of glutamine in the blood is much greater than all other amino acids and is transported and metabolized in the majority of tissues. L-glutamine may help replenish the body after trauma and/or stress, and it may possess anti-inflammatory effects. Other benefits of glutamine include improved protein metabolism and stimulated growth hormone production. Our powder contains 4,500 mg of glutamine per serving. NSI L-Glutamine Powder is better because it:. Mixes easily with water or your favorite juice. May help enhance muscle recovery.  . Did You Know? All NSI supplements are packaged in HDPE (High Density Polyethylene) bottles. These bottles keep moisture vapor out, protecting the freshness and integrity of their contents, and are 400% more effective compared other brands currently using PET (Polyethylene Terephthalate) bottles. HDPE bottles do not break as glass can and are also recyclable so we urge you to please recycle them.

"Any athletes/mortals that are training seriously need glutamine supplementation... bodybuilders take it because they believe that it helps with muscle synthesis but to me the advantages go beyond that. Glutamine is the most abundant amino acid in the body and the main fuel for the immune system... if you've ever trained hard enough... you've probably gotten to the point where you start getting cold easily... if you havent experienced this then you're not training hard enough! Anyways, glutamine can help with... so you can train harder and more frequently... this NSI product is awesome because its pure glutamine... unlike those other product out there that mix dextrose with it to save money.... if glutamine doesnt dissolve EASILY in your water then its not pure glutamine and dont buy it!"

"Every site says this is one of the best supplements, but I didn't notice a huge difference in recovery from workouts. I won't buy this again since it only helps a little but it might work better for you. I prefer Animal stak and creatine since this product is so costly for what you get."

"First experience with NSI products and I was pleasantly surprised at how effective the combination of L-glutamate and Creapure are in terms of muscle recovery. I can lift as hard as a I can for over an hour and the day after I could do it all over again. With the price you cannot go wrong and being able to maximize your workouts is so valuable!"

L-Glutamine for weight loss, February 4, 2009
By Aruban from Austin, Texas

"My bariatric doctor recommend L-Glutamine to reduce my craving for sweets. It is also used by alcoholics to reduce alcohol craving. Seems to work ok. I add a teaspoon to my "shake" snacks, which are made with two scoops of EAS 100% Whey Protein and an 8 oz glass of water."

"Other L-Glutamine Powders I have tried gave noticeable results...whereas this one makes me wonder if it is actually working.

Also other powders I have tried had barely any taste at all, this product changes te flavor of anything I add it too.

The price however cannot be beat...but I am not sure it's worth it to have a whole lot of bad tasting powder that makes me wonder if it's working or not...

So far the best I've tried is from Jarrow Formulas, but it is expensive.."
