I can't say enough good things about this product. First, I use a lot of Source Naturals products, and in my experience, they are always of high quality at a very reasonable price.<br /><br />Now as to why I'm taking this supplement...I'm working on recovering from chronic fatigue syndrome caused by leaky gut and gut dysbiosis (severe Candida infection for the last several years). I've read that people take 15-20 g of this a day to heal the gut. I started taking it on an empty stomach before meals, and the effects have been life-changing; and, no, I'm not being dramatic. It turns out that during times of stress, glutamine in the skeletal muscle can become depleted by up to 50% (perhaps even more based on some statistics I've read). The body needs glutamine to fuel immune cells and to repair tissues; the liver needs glutamine for detoxification, etc. So the body snags from skeletal muscle the glutamine that it needs. Although the body is able to make glutamine from other amino acids in the diet, during periods of prolonged stress (like chronic infection or disease), the diet simply is unable to provide a sufficient supply. This has certainly been true in my case. I seem to eat and eat all day long, but it's never enough for all the repair that is going on inside my body - yet I still have no energy. It's frustrating. This product has changed that. I'm not miraculously cured or anything like that, but it has certainly made a big difference in my quality of life as I continue to recover. I've got a lot more energy now, much less muscle aches, less difficulty digesting, and less allergies after eating. I am able to sleep through the night without waking due to hypoglycemia, and I no longer wake in the morning with muscle pain and fatigue. In short, I just feel a heck of a lot better.<br /><br />I can't speak for everyone, of course, but in my experience, I recommend that anyone working on recovering from a chronic illness take glutamine. Sift through the scientific journal articles online; many studies have been done, particularly on its effectiveness on healing and protecting the gut.

All my online research about IBS and other forms of colitis, recommend l-Glutamine for healing the intestines. It helps restore the lining. After my original diagnosis, I started using this brand of L-glutamine daily, and it helped immediately.<br /><br />It also cuts down on sugar cravings. You can't beat that!

Considering that this product is only so much money it is very well worth the price but let me tell you about what it does. I'm a bodybuilder only a teen though. Glutamine in my experience helps recover so much faster. I don't know how to explain in how it does that but I feel much more energized. Not so much like caffeine energy but it even helps me foucslike doing simple things like driving, and become alert as it is a Neuro-transmitter.<br /><br />Another important thing to note is that if you live in the U.S or in the western side of the world then this may benefit you highly since most foods on the western side are acidic. Glutamine ups the alkaline reserves in your body so you don't metabolize your muscles, and have and acidic ph level in your system.<br /><br />In the end this is great product. I've felt better by using it, but I don't know how much muscle growth I really got helped from it since muscle growth is great there is no real way to shrink my muscles and re-test.

This has to be the best L-Glutamine on the market! I feel it's effects immediately after taking it. Source Naturals L-Glutamine is more potent (pure) than Vitamin Shoppe's L-Glutamine (I tried them both). This product not only helps out with my muscles, but it also calms me down as L-Glutamine works as a natural tranquilizer.

This stuff seems to make me really sleepy. If I take it before going to bed, I sleep a few hours longer than usual. Some say that this is a pre-workout suppliment - claiming it helps offset your depleted l-glutamine levels, allowing you to workout with more energy. Others say it is a post-workout suppliment, and it should be taken within 2 hours of going to bed to increase human growth hormone levels while you sleep. It's also supposed to keep muscle cells from being broken down, so you could take it on days that you don't workout to prevent catabolic processes.<br /><br />I got it mainly to enhance recovery times. I haven't strained myself enough to notice any difference, though. Judging by how sleepy it makes me, I think that it works. Just remember that it doesn't take much to take an effect. They say you only need 2-5grams per serving. This was the best deal I could find on this stuff.

I LOVE THIS STUFF! I wish I had discovered this years ago - it has helped my life in 3-4 ways<br />- Reduced sugar/alcohol cravings and improved concentraion - under times of stress I can get into ADHD/anxiety spirals and have massive cravings for sweets and wine and since I started taking this 3x a day (1 tsp) I am just more even keeled - my appetite is if anything diminished a bit and even when I have severe work stress I don't reach for candy and ADDITIONALLY instead of getting spun off into some non-productive anxiety sprial I am able to focus at task at hand and just get it done. Overall I feel more calm and focused. Losing a few lbs to due to not being subject to the stress eating/drinking.<br />- Improved recovery from workouts and improved performance - I have been an avid exerciser for years and as I have gotten older if I do a hard workout (in gym or strenous hilly hike) I really feel it the next day in life and if I try to workout. I also started feeling like I wasn't as strong - legs hurt more on hills, was just depleted of energy faster. This week I did a hard hike (8 miles, 1700 elevation gain) I haven't done in awhile and I really noticed how much less sore I was during and after and my energy was sooo improved -I flew up that hill and nearly beat my best time for that hike.<br />- I am seeing better results from my workouts - maybe is because I can be more consistent , but I am leaning out and definitely changing fat to muscle in my overall body compostion. I havent seen changes in my body like this since I was working out hard when I was much (20yrs) younger. Its super motivating.
