PERQUE Endura / PAK Guard™ is a patented supplement that enhances energy production by safely increasing glutamine levels in the brain, muscles, and gut. This unique combination of L-glutamine and pyridoxal alpha-ketoglutarate (PAK) supports digestive health, boosts stamina, and sharpens mental clarity. The PAK component naturally recycles L-glutamine, allowing the body to utilize it repeatedly without the risk of glutamate buildup, a powerful excitatory neurotoxin that can damage nerves.
