Fuel up your muscles and your mind with the amino acid nutrition of Swanson L-glutamine. The most abundant amino acid in the skeletal muscles, glutamine has a molecular structure that allows it to pass easily through the blood/ brain barrier to nourish brain tissues. Once in the brain, glutamine is converted into glutamic acid, an essential neurotransmitter for healthy cerebral function.*

Rated 5 out of 5 by from Great Product L-Glutamine was recommended to my by a physician at a weight loss clinic. He said that it would help curb any sweet cravings. I've searched and searched for good prices and good products of L-Glutamine for the last 10 years. Swanson has met those needs. It works great. Thanks.

Rated 5 out of 5 by from Swanson L-Glutamine Most people take Glutamine after a workout to help with muscle recover. I take one in the morning (before breakfast), and one in the early afternoon for extra alertness, mental sharpness and better attitude. It seems to help a little, not a LOT, but enough to notice. I will continue to keep taking this.

Rated 5 out of 5 by from Love this stuff! I originally purchased this product for my teenage son's workout regimine, but I noticed that it also, "keeps your mind sharp and keen." IT ABSOLUTELY DOES! No longer do I walk into a room and forget why I am there! I actually remember to bring my grocery list to the store with me! My mind is noticably sharper and keener. It truly has been a God-send for me. Thank you, Swanson, for making it so affordable and convenient.
