What is glutamine and why is it important for athletes?

Glutamine is the most abundant free amino acid in skeletal muscle and blood plasma. Although the body can synthesize it, its demand increases significantly during and after intense physical exercise. Under these conditions, L-glutamine supplementation helps to:

• Counteract post-exercise immunosuppression: glutamine is the main energy substrate for lymphocytes and macrophages. After intense sessions, plasma levels decrease, compromising immune function.
• Support muscle recovery: it contributes to a positive nitrogen balance, promoting protein synthesis and reducing muscle breakdown.
• Replenish glycogen stores: it enhances muscle glycogen resynthesis after exercise.
• Improve cellular hydration: it acts synergistically with creatine to optimize cell volume.
• Optimize nutrient absorption: glutamine is the main fuel for enterocytes, helping maintain intestinal barrier integrity.

Why Kyowa® Quality?

Not all glutamines are the same. Kyowa® Quality is the quality seal of Kyowa Hakko Bio Co., Ltd. (Japan), ensuring:

• Production through natural fermentation (not chemical synthesis).
• Purity above 99%, verified by independent analysis.
• Full batch traceability.
• Compliance with international standards (GRAS, USP, cGMP).
