Glutamine Powder

Anti-Catabolic Super Nutrient


  • Premium Grade Bodybuilding Staple

  • Helps Prevent Muscle Breakdown

  • Enhances Protein Synthesis

  • 100% Pure Free-Form L-Glutamine

  • 120 Servings Per Container

Glutamine is the most abundant free amino acid in muscle tissue, which means that pure, free-form L-glutamine, taken before and after intense exercise serves the bodybuilder like few other supplements. This difference-making amino works by helping to combat muscle breakdown, helping to increase protein synthesis and nitrogen retention, enhancing cell volumization and supporting an overall potent anti-catabolic response.

That's why supplementation with ProSource's free-form L-Glutamine is an indispensable component of the serious athlete's bodybuilding regimen.
Recent research also reveals that glutamine's value goes beyond enhanced muscle recovery and repair. In fact, one landmark study has reported that L-glutamine supplementation can increase body weight, body cell mass, and intracellular water in a manner not unlike Creatine monohydrate. Finally, clinical research suggests that glutamine is essential for maintaining intestinal function, immune response, and amino acid homeostasis during periods of severe stress (such as intense exercise).

Few compounds in your arsenal do more for you than this extraordinary super nutrient. Keep your hard-earned mass gains—put the brakes on catabolism and find out why it’s called bodybuilding’s most important amino acid with 100% pure, free form L-Glutamine from ProSource. Just one teaspoon (5 grams) per serving provides the essential benefits every bodybuilder needs to grow at maximum capacity.

(Each batch of ProSource L-Glutamine is tested and certified to be 100% pure by an independent analytical laboratory using the HPLC (high pressure liquid chromatography) method of analysis.)

I'm very pleased with the Glutamine product from ProSource. The website was very easy to use and the product was received in a very timely manner. I will continue to use

Great for recovery. can not beat the price
(Posted on 2/24/2015)
Being a 67 year old extreme body builder, I would choose no other product then Glutamine. Best results come when I stack with Viagra. Gets my blood pumping real nice
(Posted on 2/24/2015)
My most essential and most highly recommended body-enhancing aid for recovery and growth. Quality and price unmatched elsewhere. Cannot rate a supplement any higher.
(Posted on 12/16/2014)
helps with recovery
(Posted on 12/15/2014)
I take it post workout and again prior to bed. I take very few supplements, but this one is a must for faster recovery.
(Posted on 11/18/2014)
Very underrated amino. I take post workout for recovery. Good value. Great product.
(Posted on 11/4/2014)
mainstay in my supplements. keeps me healthy. have not been sick in 2 yrs.
(Posted on 9/15/2014)
Been using glutamine for years and it is a great product. Would like to see prosource make it flavored like fruit punch or watermelon. I like the powder better than the caps.
(Posted on 8/25/2014)
Great product. Only drawback is that the opening on the bottle is small and hard to get the hand in to maneuver the scooper.
(Posted on 7/19/2014)
Good product at a good price.

I have purchased several bottles now and they have a been, to me at least, to be of the same quality.
(Posted on 6/15/2014)
The most basic building block. Read the research, intake of glutamine triggers muscle building hormones. No need for fancy powders. Tasteless, add it to anything. Simple. Cheap. Real.
(Posted on 6/11/2014)
Really helps with reducing soreness after a tough workout.
(Posted on 5/1/2014)
I mix this with my recovery drink. It helps feed the muscles after a hard work out. It's also good for peptic ulcers.
(Posted on 4/1/2014)
Great product and at a great price.
(Posted on 2/21/2014)
used a few different glutamine powders in the past this seems to be the first one that is showing any signs of making a difference
(Posted on 2/12/2014)
Good Stuff.
(Posted on 1/31/2014)
Really helps with recovery, i took about 10-15 grams daily (5g pre, 5g post and 5g before to sleep).
BUT....they need to provide the scoop with it. Will buy again.
(Posted on 1/29/2014)
A must have.
(Posted on 1/16/2014)
Tasteless and mixes fairly well. I have been using this product for over 9 years and it has been a proven staple in my nutritional arsenal. I would highly recommend adding a scoop to the bottle. Great price and quality!
(Posted on 11/2/2013)
Not too sure if it really does anything. I'm still sore 2 days after a workout. Only using 5grams after a workout and 5 before bedtime. Will keep at it though.
(Posted on 10/25/2013)
Just started on it seems to be helping with recovery. great price. will continue to use it
(Posted on 10/12/2013)
Excellent product. I take 5g pre&post workout. haven't loaded on it and it really seems to help with post work out recovery and muscle soreness. Mixes well and has no taste.
(Posted on 9/24/2013)
Cuts recovery time but needs to come with a measuring spoon. I use to take before and after workouts but after is all that's needed as i haven't noticed a difference
(Posted on 8/17/2013)
Good , doesn't come with measurement scoop. Need to work on that.
(Posted on 8/8/2013)
I've been using glutamine, from various manufacturers, for over 25 years! It always facilitates quicker recovery and quick improvements in muscle growth! I need these effects, since I'm training to be in shape for doing "P-90-X" again ! I'm pushing 71 yrs of age!
(Posted on 7/20/2013)
Absolutely tasteless and absolutely effective. Best glutamine powder on the market; hands-down! Great price for such an effective supplement.
(Posted on 7/20/2013)
If you want to get bigger, get glutamine. I take about 20 grams a day and I get really great results. Prosource's offering is super easy to mix, tasteless, and about as pure and effective as I've tried. The price point is nice for the amount you get. Just make sure you use enough. Research shows that dosages between 20-30g daily are best.
(Posted on 7/12/2013)
Great stuff!! Best glutamine--hands down!! This with prosource Creatine are a great combo for strength and size. Great price too. Excellent after workouts, and before bed.
(Posted on 6/29/2013)
I mix with juice to hide any taste. I have in the morning and after I work out sometimes before bed. Great for recovery.
(Posted on 6/26/2013)
Mixes well. no clumping. not very tasty but works great. cut my recovery time in half.
(Posted on 6/22/2013)
I can feel this product help in my recovery after an intense workout.
(Posted on 6/14/2013)
I take 5g twice a day. This stuff sliced my recovery time in half! Great product, great price, can't beat it.
(Posted on 4/5/2013)
mixes easy, use pre/post workout and at bedtime, great stuff
(Posted on 3/25/2013)
I like this stuff. It helps cut down my muscle soreness noticeably compared to using nothing.
(Posted on 2/17/2013)
Must have if you're lifting heavy. Cuts down on muscle soreness and recovery time.
(Posted on 1/27/2013)
this is a must if your into building muscle.
(Posted on 1/23/2013)
Put this in all my protein shakes to bump up the glut content. Use it pre/post and night.
(Posted on 12/29/2012)
Stuff is great. My recovery is increasingly noticeable prior to not taking this supplement, I recommend this product to anyone.
(Posted on 10/20/2012)
Great stuff! Cheaper than the rest but the same if not better quality.
(Posted on 9/26/2012)
For the money this is the best Glutamine product. I take 5 grams first thing in the morning on a empty stomache, sip 5 grams while I work our and before bed.. I can feel the difference being on it for 2 weeks now
(Posted on 9/15/2012)
Has no funny taste, works great and a good value.
(Posted on 7/16/2012)
Great product mixes very well with no taste. Very good price !
(Posted on 7/12/2012)
Ordered this and the BCAA Powder from Prosource and I have seen good results. Would recommend this to anybody, I feel great when I take it and its very affordable even on the tightest budget.
(Posted on 7/7/2012)
Every Pro Source product I've tried so far is of great quality and their Glutamine is no exception. 120 servings for under $19? You wont find a better bargain anywhere. Not with this type of quality.
(Posted on 4/9/2012)
Great product for a great price. Mixes well with anything. I would recommend this product.
(Posted on 3/8/2012)
I'm giving it 4* right now because I have only been taking this for a week and haven't seen the full results yet. ZERO taste!!! Mixes easily with anything ... I will update after a month or so
(Posted on 2/18/2012)
Love it! Only change this month and 5 solid pounds!!
(Posted on 2/12/2012)
Good product. Definitely helps take the edge off those deep painful sorenesses.
(Posted on 1/7/2012)
Good stuff. Helps you recover quicker. I can tell when I don't take it!!!
(Posted on 12/23/2011)
A must for the hardcore liter. It really aids in the recovery process. I add it to every protein shake that I drink
(Posted on 11/15/2011)
Best price and quality you can get. Been using it for over 15 years. Mixes easily with water and has zero taste. No excuse not to take this most important supplement. Seriously, if you can't afford to take anything else at least take this.
(Posted on 11/2/2011)
Great product. An athlete has to have this product. Buy it and use daily.
(Posted on 9/29/2011)
Great product , great results. I can really feel a difference when using glutamine. I stack it with creatine and protein. I recommend to anyone.
(Posted on 7/31/2011)
The MOST important amino if you trying to put on major mass. Some say you don't need it but those are the ones who's broken down like 89 Yugo.
(Posted on 7/29/2011)
the only amino you need!
(Posted on 7/23/2011)
Excellent product. It is also very good value.
(Posted on 7/17/2011)
A little bit on the expensive side, but it's good. It's my second one and I'm satisfied. Dissolves well. It lasts a long time. I heard you must not mix with creatine. Take 30-45 min apart because they counter react.
(Posted on 7/14/2011)
Excellent consistency and zero flavor. Highly recommended.
(Posted on 7/11/2011)
I mixed with Prosource's creatine and beta alanine for great results.
(Posted on 6/23/2011)
Best Stuff on the Market. Also like it has no taste
(Posted on 6/13/2011)
Does what I need it to do.............
(Posted on 5/15/2011)
Helps the recovery process a lot.
(Posted on 4/23/2011)
Great product...clean glutamine...
(Posted on 4/16/2011)
I love this. It makes me feel good. It works
(Posted on 4/13/2011)
The best recovery product on the market. I've use it for years.
(Posted on 4/11/2011)
Standard product at a fair price. Exactly what I was looking for.
(Posted on 4/5/2011)
Very good solid product. for the price this is a good deal. nice job Prosource
(Posted on 10/18/2010)
I love this stuff. I'm now in my 30's and don't recover from workouts like I used to. this product really helps with that. faster recovery less time between workouts bigger and stronger in a shorter amount of time. Also, $19 for 600g is a heck of a value.
(Posted on 6/1/2010)
Best buy,recover well after workouts
(Posted on 3/4/2010)
Very dissappointed with this ProSource product.
Good price for the quantity, as compared to EAS Glutamine. But that's all I have positive to say about this produ
(Posted on 1/17/2010)
Why pay more for inferior overpriced products.
(Posted on 12/29/2009)
Works great, got a lot of size and faster recovery from it.
