Put this in your protein shake and you won't even notice it. At the very least you should get a placebo effect. (Posted on 1/24/12)

totally affordable, tasteless, WORKS. Always a part of my training stash. Been using it for months, it really makes a difference. I feel stronger and recover a lot faster. Thanks ON (Posted on 1/24/12)

Wow, this powder is like silk, yet it doesn't fly away, but mixes instantly with no taste. One only needs a rounded teaspoon per day, so it will last a long time. (Posted on 1/24/12)

I've been taking this product for a couple of weeks now. I can definitely notice shorter recovery times after heavy lifts. Whereas before I used to be sore for 3-4 days after a super-intense chest workout, I'm now sore maximum 1 day and fully recovered after 2. Flavor is unnoticeable but slightly gritty if consuming more than recommended in a glass of juice. Powder is totally unnoticeable in protein shake, which is how I typically consume it.

I have good results with this glutamine,working together with the same brand protein!! (Posted on 1/24/12)

Chances are if you're reading this review, you already know how great Glutamine is. In case you don't: it helps you build muscle, lose weight, and protects your muscles to ensure that as you're losing weight, you're cutting fat instead of muscle. This is one reason you'll see Glutamine as a key ingredient of most weight-loss supplements on the market. As a result, it's a great thing to add to your protein shakes no matter what your goal is - cutting, gaining, or maintaining.

As with its Creatine and Gold Standard 100% Whey, Optimum Nutrition excels at giving us simple products at affordable prices without a bunch of glitz and extra junk we don't need. Just add a teaspoon of this to a shake or smoothie 2-3 times a day to help boost your progress, no matter what your goal is, and you won't be disappointed. (Posted on 1/24/12)

I take Glutamine 3x per day along with my health & workout routine. I also use Creatine & BCAA. All combined, I feel healthier & more energetic. I can hit the gym nearly everyday without any problems. It's also so easy to mix with water with absolutely no flavor... which makes drinking Glutamine perfect since there isn't an aftertaste. Will re-order. (Posted on 1/24/12)

I don't think I've ever been as surprised by how well a product as I have been with this. I put a teaspoon of this in with my regular protein shake mix after a long lifting session, and was happy to find that the next few days were soreness-free. I had a very slight dull ache on occasion, but nothing compared to what it is without it. And, at a serving size of 1-2 teaspoons, this tub will last a long long time. (Posted on 1/24/12)

This is the first time I've used Glutamine so i don't have a point of comparison. The product is a big help in recuperation after my workouts and has given me good results. (Posted on 1/24/12)

This product is a steal. Glutamine is an insane recovery agent that can allow for a person to fully recover within shorter periods of time. Because this product speeds up the recovery process, it is ultimately speeding up muscle growth. My opinion is glutamine is much more effective than creatine and worth every penny. Add this product to your post workout protien shake and also to any beverage before bed for best results. (Posted on 1/10/12)

I've been weightlifting for a couple years now on and off, and have been using Glutamine Powder for about a year. Like I said in the title glutamine is no miracle supplement that will add 10 lbs. of muscle overnight (anything that claims that is total BS anyways). However, what it does claim to do is help with recovery and there is plenty of research to back that claim up. Like I said I've been working out for some time now and I wouldn't keep using a product if I didn't think it was helping. As far as why I would chose this product over any others is simple, Optimum Nutirion always puts out top quality products and their prices somehow remain competitive with , what I consider, their lower quality competition.

I think ON is a decent company and they make great products, and this is no exception. I just didnt think glutamine as a supplement helped me. I included this in my routine (I've only been training for a year and a half) and didnt notice anything more than I would have without it. I was gaining steadily before I tried glutamine and I continued at the same pace during the 2 months that I tried it. If amino acids are your thing try BCAA's. They're supposedly more effective. As for me, it's back to whey as my only supplement. (Posted on 1/10/12)

Previous to using this product I was using protein three times a day, one scoop. But my problem was that I was working out hard all week and every day my workout was getting worse than the day before. This helped reverse that trend and help my workouts hold steady then later improve. I really responded well with it.

It changes the taste a little bit of my protein powder, but that's not to say it is bad. The best way I can explain it is that it tastes like it dilutes the powder flavor. No real problem for me. (Posted on 1/10/12)

I have used a variety of supplements in my life and have found that the different manufacturers produce in widely varying levels of quality. I had recently begun buying from Optimum Nutrition because I had tried and liked their whey protein powder. When I ran out and needed more glutamine I gave ON a try. It is better quality than the crap I was using previously at least as evidenced by the reaction of my body. Glutamine in general helps me to recover more quickly after lifting. This powder dissolves quickly in most liquids and is absorbed fairly easily by my body. I would recommend this to others. (Posted on 1/10/12)

I have never disliked an Optimum Nutrition product I've tried, and this one is no exception. The 300g package gives you roughly 60 servings (each serving = 1 tsp.) of flavorless glutamine powder that mixes easily and well with every beverage I've tried so far. I usually just put it in my post-workout shakes, and you basically don't even notice it's in there. The only thing I don't like is the smell, because evidently flavorless does not mean scentless.
