What is L-Glutamine?

L-glutamine is an amino acid and one of the building blocks that make up proteins. In the human body, it is the most abundant free amino acid, with the highest concentrations in blood plasma and skeletal muscle.

L-glutamine is considered a semi-essential amino acid. This is a classification for amino acids that the body can generally produce itself.

FAQs

Is L-glutamine only for bodybuilders? +

No. L-glutamine is not tied to a specific sport. It is used by performance-oriented athletes who train regularly, face high physical demands, or want to structure their recovery phase more intentionally.

Do I even need L-glutamine if I already eat well? +

A good diet remains the foundation. Many ambitious athletes intentionally supplement their routine when training volume, intensity, or overall workload increases. Especially during demanding phases, a well-structured recovery phase can be beneficial.

Do you feel the effects of L-glutamine immediately? +

L-glutamine is not a typical “feel-it” booster. It is usually integrated into long-term routines intentionally. The focus is not on a short-term kick, but on consistency, resilience, and smarter recovery.

Why does ON.SYNC use KYOWA® L-Glutamine? +

KYOWA® stands for high-quality amino acid raw materials with strict quality standards and controlled manufacturing processes. For ON.SYNC, this means consciously selected ingredients instead of generic commodity raw materials.
