Top Customer Reviews

Flavor Name: UnflavoredSize: 1000g
Reason for buying:
I decided to buy this product because I had read from a number of reliable sources that taking Glutamine had numerous benefits and I wanted to experience them for myself.

Benefits of Glutamine:
- Increases growth hormone levels by 400%
- Boosts the immune system
- Maintains muscle cell volume
- Increases muscle protein synthesis
- Prevents muscles from being broken down
- Speeds up wound healing and recovery (muscle soreness)

Mixing and Taste:
When I first tried the product by mixing 5g (tea spoon) with a glass full of water I found that it mixed reasonably well and tasted relatively sweet and there was a lot of it left inside the glass. I then found that mixing it with my protein shake completely dissolved it and there was none left inside the glass.

Results:
After taking 1 tea spoon (5g), 3 times a day with my protein shake I found that it made a positive difference to my muscle growth, strength and muscle fatigue during workouts. I also find that I have less illnesses (sore throats, colds, coughs etc) during the flu season (October to April) and generally feel better within myself.

This was my dosage and timing: (1 tea soon = 5g)

Training days:
Immediately upon waking up (5g)
30-45 mins pre workout (5g)
Immediately after workout (5g)
60 mins before going to bed (5g)

Non Training days:
Immediately upon waking up (5g)
Lunchtime (5g)
60 mins before going to bed (5g)

Who should be taking them:
Although these supplements are designed for body builders, they can also be taken by individuals who do any fitness activities and can also be taken by individuals who do not exercise.

If you have any doubts about glutamine in general, do a web search on the benefits and see for yourself if it's something you could use. I'm 38 and still train pretty hard so at this point in my life I'll try anything legal to help me recover. I like the fact that glutamine helps in everything from repairing muscle to boosting white cell count. My close friend (43 years old) has practiced jiu jitsu for quite some time and once lived on ibuprofen to deal with the soreness after training. He's now ditched the ibuprofen all together after using 20 grams of glutamine post workout. As for this particular product, it mixes well and seems to be high quality.

I have chronic fatigue and fibromyalgia. I work out to reduce my chronic fatigue but that worsens my fibromyalgia. I take 5 grams of glutamine 3 times a day and the fibromyalgia is greatly reduced.

I've taken 500mg of other glutamine brands for years. I recently decided to increase and the Optimum Nutrition brand. I noticed an increase in strength during my weight training, reduced sugar cravings and I believe it has helped increase my immunity this winter. I will definitely continue to buy this brand.

This is the second time I have purchased this product. Mixes okay, sometimes a little gritty but might be because I don't like a lot of water in my protein shakes. I tend to get full and not want to work out if I drink too much. I use this product twice a day, pre and post workout at 5g scoops. They don't come with a scoop but I had one from some other products. What I like most about the product is that after about a week or so of using it, I do not seem to get as sore as I would otherwise. Regardless of how hard I work out. I tell all my friends to give it a god. So cheap and lasts forever.

I've used Glutamine off and on for years, mainly off, because it is really pretty expensive. However, I decided to pick up a small bottle from a local supplement store to give another try. Here is my dosing and experience:

My stack is as follows:
4 Arginine (2 Grams) and 1.5 scoops N.O. Explode (Non-Caffeinated) 1-1.25 hours pre workout
20 grams glutamine with 3 scoops ON Amino Energy 30 minutes pre workout.

This is a recently discovered God send of a stack. I increase in weight every week at a minimum of 5%, and up to 20% (The larger increase comes from the deadlift. Started at 180 and within 2 weeks was up to 240. Its been awhile since I've done them, so i needed my back to get used to it). This week alone my Deadlift increased 40 pounds (My legs are strong enough, my back isn't used to moving that kind of weight just yet). That's a 15%+ increase! Its the same for all my lifts. It sounds great, right? Well, here's the problem. When your body isn't used to constantly increasing weight, you tend to get pretty sore. That's where the magic of Glutamine comes in, well, one of the two pieces of magik anyway. The most notable is that you will either not be sore at all, or have just a trace of soreness. This allows you to lift heavier, which means increased strength and increased muscle mass. Epic.

The second great part about glutamine is that if taken at 20-25 grams (Some people apparently get an upset stomach when they take this much. I've never had a problem), you will notice increased strength, compared to if you don't use it. Hooray! And, seeing how I am a vegetarian, supplementing is important since I don't eat meat. Therefore, my Glutmaine levels are lower than most people.

Should you buy Glutamine? Well, I suppose that depends on your goals.
