Quest l-Glutamine is a superior amino acid supplement. This amino acid is one of the few compounds that can cross the blood-brain barrier and participate in brain chemistry. In the brain, l-glutamine is converted to glutamic acid, which serves as an energy source for the brain, a role that only it and glucose (blood sugar) can fulfill.

Quest was started in the 1950's by a vegetarian weightlifter who was passionate in leading the industry by providing quality products with great formulations. 'Quality without Question' was then created and followed throughout the years. Today, with Purity Life, it isn't just 'Quality without Question' - it is 'Expecting Excellence'. Quest continues to provide innovative products using a 'back-to-basics' philosophy, creating a balance of body, mind and spirit.
