Primary Function: Conditionally Essential Amino Acid
HOW IT SUPPORTS PET HEALTH
L-Glutamine is a conditionally essential amino acid that plays a critical role in maintaining digestive health, immune function, and muscle recovery in pets. While dogs and cats naturally produce L-Glutamine, certain conditions—such as illness, stress, or injury—can deplete their reserves, making supplementation beneficial. This amino acid serves as a primary fuel source for intestinal cells and immune cells, helping to repair damaged tissues and reduce inflammation.
Pets with gastrointestinal disorders like inflammatory bowel disease (IBD) or chronic diarrhea can particularly benefit from L-Glutamine’s ability to restore gut barrier integrity and promote nutrient absorption. Additionally, it supports muscle maintenance and recovery, making it valuable for aging pets or those recovering from surgery or injury.
FUNCTIONAL OVERVIEW
L-Glutamine is the most abundant amino acid in the body and is crucial for cellular energy production, particularly in rapidly dividing cells like those in the intestinal lining. It helps maintain the integrity of the gut barrier by supporting tight junction proteins and reducing intestinal permeability. This function is essential for preventing “leaky gut syndrome,” where harmful substances can pass through the intestinal wall into the bloodstream.
In addition to its digestive benefits, L-Glutamine supports immune system function by fueling lymphocytes and macrophages—key immune cells that help fight infections. It also aids in muscle protein synthesis, reducing muscle breakdown during periods of stress or illness. Together, these functions make L-Glutamine a versatile nutrient for overall health and recovery.
COMMON VETERINARY USES

- Aiding muscle maintenance in aging pets experiencing sarcopenia (muscle loss).
- Reducing inflammation in pets with autoimmune conditions or chronic allergies.
Contraindications & Sensitivities
L-Glutamine is generally safe when administered at appropriate doses. However, it should be used cautiously in pets with epilepsy or those taking anti-convulsant medications, as high doses may interfere with these treatments. Always consult a veterinarian before introducing L-Glutamine supplements to ensure proper dosing and safety for your pet’s specific needs.
