Arginine and Glutamine: Amino Acids That Support Surgical Healing
Undergoing surgery is a significant stressor and your body requires an abundance of nutrients to heal optimally, modulate inflammation, and defend against infection. Two amino acids—arginine and glutamine—are particularly important during this time. Here's what they are, why they matter, and what the science says about their role in surgical recovery.
What Are Arginine and Glutamine?
Arginine is a conditionally essential amino acid involved in wound healing, nitric oxide production, immune function, and hormone secretion. It becomes essential during periods of physiological stress, including surgery.
Glutamine is also a conditionally essential amino acid and the most abundant amino acid in the body. It is vital for immune cell function, nitrogen transport, and maintaining gut barrier integrity.
Why Are They Needed in Surgical Healing?
Surgery causes tissue injury and inflammation, increasing the body's metabolic demands. During recovery:
Arginine promotes collagen synthesis, supports wound healing, and enhances immune responses
Glutamine serves as a critical fuel source for enterocytes (gut lining cells) and immune cells, preserving gut integrity and immune defense.
Both help reduce inflammation, improve nitrogen balance, and decrease risks of infection and delayed healing.
What Do Studies Show? Peri-operative arginine and glutamine containing supplements significantly reduced surgical site infections and inflammation, shortened hospital stays and improved wounds strength in patients undergoing surgery.
Conclusion
Both arginine and glutamine are essential for healing, especially in the high-demand context of surgery. Their roles in collagen synthesis, immune support, and inflammation control make them valuable allies in the recovery process. Speak with your surgical or nutrition team to see whether these amino acids should be part of your pre- or post-op regimen.
