Glutamine is the most abundant free amino acid found in the muscles of the body. Its ability to easily pass the blood-brain barrier makes it an effective brain fuel. In the brain, glutamine is converted into glutamic acid, a neurotransmitter essential for cerebral function.*

Rated 5 out of 5 by from Plethora of benefits I book I recently read recommended this supplement. Since then I have done extensive research and have decided to add it to my health regime, knowing it is benefiting my body. Love Swanson's prices!!!!

Rated 5 out of 5 by from Swanson's L-Glutamine Most people take this after their workout, but I take one in the morning (by itself, so it doesn't compete with other amino acids for absorption), to help sharpen my mind and help me to be more alert. I have noticed a slight difference since taking it. It might not work for everybody, but it does for me.

Rated 4 out of 5 by from Great value! It's glutamine, and it's a good deal. If you're a weight lifter you need glutamine to help recovery. I highly recommend it.

Rated 5 out of 5 by from Cleanse Gem I purchased this product to use for a 3 day cleanse. It worked well for me. I am continuing this product for a few more weeks.

Rated 4 out of 5 by from Recommended by my MD My MD recommended that I start taking L-Glutamine for gut health several years ago. I don't know how it works but I noticed a big difference when I don't take it. It makes me feel better. Last year my MD recommended that I try the Swanson brand for my over-the-counter supplements because of the quality. I found the quality fine but the pricing even better. I am paying about $8 less than I paid for the other brand and getting the same or better results.

Rated 5 out of 5 by from Good purchase I take this combined with two other supplements just so that I don't feel tired throughout the day. I take this one along with B-complex 100 and with Phosphatidylserine. All three combined once in the morning with breakfast and once again during lunch time make a serious difference. I don't feel tired or sleepy during the day with these three. I don't yawn or anything. If you take L-Glutamine by itself, yeah you will notice it since it does make your mind more alert but like I said, combining it with the other two make for a perfect trio to keep you fully awake and alert throughout the day. It works for me. I am 25 and I work in IT and I go everyday like nothing but if I mess up and don't take them, I feel it. It's not a tremendous drop but later at night at home I feel much more tired than usual.

Rated 5 out of 5 by from My best energy booster I have taken L-Glutamine since over fifteen years now; it boosts my energy for my morning Yoga and exercise--and in the afternoon, it perks me up for my afternoon walk.

Rated 4 out of 5 by from Undecided I'm 50/50 on L-Glutamine. I feel at times it helps with brain function and energy levels, but other times I feel a bit weird afterward. I can only guess that I have a sensitivity to glutamine. I think people who have trouble with sodium glutamate in foods, like I do, may want to think twice about this product.

Rated 5 out of 5 by from Great Help after Exercise I have begun strength training and read about Glutamine being a great help for after-exercise discomfort. It helps me a lot and greatly reduced the down time from my first few weeks of lifting. Plus, it's much cheaper than any other place I have checked out.

Rated 5 out of 5 by from Keeps my brain healthy My husband and I both take one L-Glutamine on an empty stomach twice a day to help our brains 'work' and rejuvenate. We're both over 1/2 a century old and enjoy clear thinking and want to keep it that way.

Rated 5 out of 5 by from L-Glitamine Great for people that workout or train for a sport. It helps me with some of the muscle pains you get the next day after training. Since taking this, I've noticed a great level of endurance and strength and my muscles don't hurt or ache the next day.
