L-glutamine is a “conditionally essential” amino acid which plays important roles in immune function and tissue repair.1, 6 L-glutamine can also cross the blood brain barrier, and can be (safely) converted to the neurotransmitters glutamate and GABA in the brain.2 Unlike glutamate ingestion (e.g. MSG), the conversion of L-glutamine to glutamate is highly regulated, so the likelihood of side effects is negligible.2 L-glutamine supplementation helps support immune function, tissue repair (including from exercise), and may help with cognitive performance.3, 4, 5, 6
