L-glutamine: The perfect supplement for athletes

L-glutamine is the perfect supplement for athletes who are looking to boost their performance and recovery. Glutamine increases muscle growth, supports immune function, and helps to maintain healthy glycogen stores. It also aids in post-workout recovery, especially after intense exercise. When levels of glutamine are depleted during periods of intense and prolonged exercise, protein synthesis can be limited. Supplementing your diet with glutamine powder is the best way to ensure that you have good levels of this important amino acid. Our pure pharmaceutical grade glutamine powder is unflavored so you can mix it with water, juice, or a protein shake. It’s also suitable for vegans and vegetarians. This halal certified product is made in the UK.
