More Than a Single Amino Acid
L-Glutamine is found naturally in protein-rich foods including meat, fish, dairy and legumes. It is the most abundant free amino acid in human muscle tissue and plasma. For people who train regularly, dietary sources alone may not always match the demands placed on the body, which is why L-Glutamine has become one of the foundational amino acids in sports nutrition. A single-ingredient formulation lets you decide the dose and frequency that fits your own routine, without fixed serving sizes or combined formulas that limit flexibility.
Making It Part of Your Daily Routine
L-Glutamine is typically taken on an empty stomach or alongside a light carbohydrate-only snack — many people include it in their pre- or post-training routine. At one capsule per day, a 90-capsule bottle lasts three months; those who prefer a larger daily amount can adjust accordingly. It fits neatly into any existing supplement routine as a simple, clean addition.
About L-Glutamine
Glutamine is a conditionally essential amino acid, meaning the body can synthesise it under normal circumstances but may draw on dietary or supplemental sources when demands are higher. It accounts for approximately 60% of the free amino acid pool in skeletal muscle, which is why it has attracted sustained interest in the sports and fitness nutrition community since the 1980s. Research into glutamine continues across a range of nutritional contexts. This product provides the amino acid in its free-form state, which is absorbed and utilised without requiring prior digestion or conversion.
