Clinical strength joint support for cats and dogs


The ingredients in VETRIFLEX® reduce pain and inflammation while repairing and restoring joint health.2-4 It’s a joint effort.

VETRIFLEX® contains extensively researched ingredients including:


CurcuVET® (Curcumin Phytosome®

  • Mimics the anti-inflammatory activity of an NSAID3,5
  • Potent COX-2 inhibitor5

Perna canaliculus (GlycOmega™ green-lipped mussel)

  • With 57 nutritional factors
  • Improves articular cartilage viscosity, flexibility, and tensile strength4

Phytosome® technology

  • Powering curcumin, Boswellia, and grape seed extract
  • Provides superior bioavailability6

Intervene early with clinically proven, all-natural, Health Canada–approved (NN. N9C8) VETRIFLEX® joint formula for cats and dogs.

  • Extensive studies have proven CurcuVET® to be a potent COX-2 inhibitor.5
  • A recent study compared the bioactivity of CurcuVET® to NSAIDs, finding that CurcuVET® was effective in helping to maintain the markers associated with a normal inflammatory response in canines.2
  • Boswellia has been used in Indian Ayurvedic medicine for centuries for reducing pain and inflammation. In several studies, boswellic acids have been found to have anti-inflammatory activity similar to that of the NSAIDs used in conventional medicine.7
  • Unlike NSAIDs, the botanicals curcumin and Boswellia are well-tolerated and are unlikely to cause adverse effects on kidney function, or cause stomach irritation or ulceration.2,7,8

Perna canaliculus is a green-lipped mussel obtained from a sustainable New Zealand source. It contains:

  • Essential Fatty Acids (Omega 3, 6, and 9): Natural anti-inflammatory components that are not produced by the body
  • Chondroitin Sulfates: The principal component of cartilage – the shock absorbers for joints
  • Hyaluronic Acid: Necessary for maintaining the proper viscosity of synovial fluid surrounding the joint
  • Natural Glucosamine: A key building block for healthy cartilage
  • Amino Acids: Contains all 21 essential and non-essential amino acids – the building blocks of all bodily tissue
  • Minerals: Important cofactors for bone and cartilage health4

NUTRITIONAL FACTORS needed for improved viscosity, flexibility, and tensile strength of the articular cartilage.4


Poor bioavailability of polyphenolics can be improved using the Phytosome® technology delivery system, a strategy that enhances the rate and the extent of solubilization into aqueous intestinal fluids and the capacity to cross biomembranes. In the Phytosome® process, an ingredient becomes an integral part of the lipid membrane, thus improving its systemic bioavailability when administered orally.6



  • Pharmacokinetic studies demonstrate a nearly 30-fold increase in bioavailability when compared to standard curcumin extracts.9
  • The proprietary Phytosome® technology combines curcumin and phosphatidylcholine in a 1:2 ratio promoting efficient absorption across membranes. This produces significantly higher peak plasma concentrations and larger area under concentration-time curves (AUC).5


  • The bioavailability of boswellic acids from Casperome® is greatly optimized both at the plasma and tissue levels.10
  • Studies show that serum levels of KBA (11-keto-ß-Boswellic acid) are increased sevenfold, and serum levels of ß-Boswellic acid can be increased threefold, when compared to non-formulated extracts.10


  • Research has demonstrated LeucoSelect®‘s ability to reduce oxidative stress and support plasma antioxidant defenses, both in physiological and clinical conditions.11
Phytosomes bind an herbal extract to a phospholipid. This unique Phytosome® Complex easily crosses the gut barrier resulting in significantly higher blood levels of the ingredients they are attached to.


VETRIFLEX® features the clinically proven GlycoFlex® 3 formula, which showed a 41% increase in hind leg strength in four weeks, plus additional herbal extracts.12

Peak Vertical Force (PVF)

Treatment dogs showed a 41% increase in peak vertical force after 4 weeks of treatment with GlycoFlex® 3 compared to pretreatment values.

Synovial Prostaglandin E2 (PGE2) Concentration

After 6 weeks of treatment, mean synovial prostaglandin E2 levels were significantly lower in the responder treatment group compared to the responder control group.
