"Great value, does exactly what it says. Helps me focus and de-clutter my thoughts, I will definitely be repurchasing again in the future!" ~ product review by Joanimal

  • Keeps your mind sharp and keen

  • Helps fuel your muscles

  • Has a unique ability to pass through the blood/brain barrier, making it an excellent promoter of healthy mental function

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.

L-Glutamine 4.6 5 11 23
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. February 17, 2014
generic your version of generics apparently don''t have any potency. I took your products for muscle testing, and they came back as placebos. Even your buffered vitamin c October 26, 2013

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. February 4, 2010
