N-Acetyl-D-Glucosamine (NAG)

Primary Function: Joint Support, Gut Health, and Urinary Tract Health

HOW IT SUPPORTS PET HEALTH

N-Acetyl-D-Glucosamine (NAG) is an amino sugar derived from glucose that plays a vital role in maintaining joint health, gastrointestinal integrity, and urinary tract function in pets. As a precursor to glycosaminoglycans (GAGs), NAG contributes to the structural integrity of cartilage, the protective mucosal lining of the gut, and the bladder wall. This makes it particularly beneficial for pets with arthritis, inflammatory bowel disease (IBD), or interstitial cystitis.

By reducing inflammation and promoting tissue repair, NAG supports mobility in aging pets and helps restore gut and bladder health in those with chronic conditions. Its ability to enhance mucus production and strengthen connective tissues makes it a versatile nutrient for improving overall health and quality of life in dogs and cats.

FUNCTIONAL OVERVIEW

NAG is involved in the biosynthesis of glycosaminoglycans (GAGs), which are essential for maintaining healthy cartilage, gut lining, and bladder walls. In joints, GAGs help cushion and lubricate cartilage, reducing discomfort caused by inflammation or wear-and-tear. In the gastrointestinal tract, GAGs contribute to the protective mucosal barrier that prevents harmful substances from passing into the bloodstream.

In urinary health, NAG strengthens the GAG layer lining the bladder wall, protecting it from irritation caused by urine. This function is especially important for pets with interstitial cystitis or other urinary tract conditions. Additionally, NAG’s anti-inflammatory properties make it effective in managing chronic conditions like arthritis or IBD.

COMMON VETERINARY USES
Species Studied
  • Dogs
  • Cats
Primary Benefits for Pets
  • Joint Health: Supports cartilage repair and improves lubrication in pets with arthritis or joint discomfort.
  • Gut Integrity: Promotes a healthy mucosal barrier in pets with gastrointestinal disorders like IBD.
  • Urinary Tract Health: Strengthens bladder walls to reduce discomfort caused by interstitial cystitis or other urinary conditions.
  • Anti-Inflammatory Effects: Reduces inflammation in joints, the digestive tract, and urinary system.
Veterinary Use Cases
  • Treating arthritis or joint degeneration by promoting cartilage repair and reducing inflammation.
  • Managing gastrointestinal disorders such as IBD by restoring gut barrier integrity.
  • Supporting recovery from urinary tract conditions such as interstitial cystitis by strengthening bladder walls.
  • Aiding mobility in senior pets experiencing age-related joint stiffness.
Contraindications & Sensitivities

N-Acetyl-D-Glucosamine is generally safe when administered at appropriate doses. However, it should be used cautiously in pets with shellfish allergies, as glucosamine derivatives are often sourced from shellfish. Always consult a veterinarian before introducing NAG supplements to ensure proper dosing and safety for your pet’s specific needs.

INGREDIENT SOURCING & QUALITY STANDARDS

N-Acetyl-D-Glucosamine is typically derived from shellfish through a process that ensures high purity and bioavailability. The form used in ThorneVet products meets rigorous quality control standards to guarantee consistent safety and efficacy. This ensures your pet receives reliable support for joint health, gut integrity, and urinary tract function.
