Clinical Trials

We have always felt that, where possible, studies should be conducted to support our product efficacy. We’ve worked with universities and colleges across the country to ensure our clinical trials are accurate, independent and fair. As a result of these relationships, we’ve carried a number of clinical studies, which have been published and made available to veterinarians. This ensures they’re totally confident when recommending our products to pet owners.

Randomised double blind, positive controlled trial to assess the efficacy of glucosamine/chondroitin sulfate for the treatment of dogs with osteoarthritis

Thirty-five dogs were included in a randomised, double-blind, positive controlled, multi-centre trial to assess the efficacy of an orally administered glucosamine hydrochloride and chondroitin sulfate (Glu/CS) combination for the treatment of confirmed osteoarthritis of hips or elbows. Carprofen was used as a positive control. Dogs were re-examined on days 14, 42 and 70 after initiation of treatment. Medication was then withdrawn and dogs re-assessed on day 98. Response to treatment was based on subjective evaluation by participating veterinarians who recorded their findings at each visit. Dogs treated with Glu/CS showed statistically significant improvements in scores for pain, weight-bearing and severity of the condition by day 70 (P < 0.001). Onset of significant response was slower for Glu/CS than for carprofen-treated dogs. The results show that Glu/CS has a positive clinical effect in dogs with osteoarthritis.


A blinded randomised controlled trial to determine the effect of enteric coating on enzyme treatment for canine exocrine pancreatic insufficiency

Enzyme treatment is the mainstay for management of exocrine pancreatic insufficiency (EPI) in dogs. ‘Enteric-coated’ preparations have been developed to protect the enzyme from degradation in the stomach, but their efficacy has not been critically evaluated. The hypothesis of the current study was that enteric coating would have no effect on the efficacy of pancreatic enzyme treatment for dogs with EPI.

Thirty-eight client owned dogs with naturally occurring EPI were included in this multicentre, blinded, randomised controlled trial. Dogs received either an enteric-coated enzyme preparation (test treatment) or an identical preparation without the enteric coating (control treatment) over a period of 56 days.


Effects of oral administration of N-acetyl-D-glucosamine on plasma and urine concentrations of glycosaminoglycans in cats with idiopathic cystitis

To determine the effects of once-daily oral administration of N-acetyl-D-glucosamine (NAG) on plasma and urine glycosaminoglycan (GAG) concentrations in cats with idiopathic cystitis (IC).


Nutritional supplementation in cases of canine cognitive dysfunction

Canine cognitive dysfunction (CCD) is a clinical condition, which impacts significantly on the lives of elderly dogs and their owners. It is hypothesised that nutritional supplementation can be used in the management of the condition and this trial was designed to investigate the therapeutics effects of a specific supplement when compared to a placebo. The trial was conducted in a clinical context and involved 20 UK veterinary practices, giving geographical spread across the country. The duration of the trial was 56 days, including a baseline period of 7 days and a post-trial period of 7 days. There was a significant difference between the treated and the placebo groups in relation to improvement in their scores for disorientation, changes in interaction and house soiling behaviour at day 21, day 28 and day 42. These results support the clinical practice of nutritional supplementation as a valuable component of the therapeutics approach in cases of canine cognitive dysfunction.


Double blind investigation of the effects of oral supplementation of combined glucosamine hydrochloride (GHCL) and chondroitin sulphate (CS) on stride characteristics of veteran horses

Reasons for performing study: Oral chondroprotective supplements are commercially popular for veteran (and other athletic or arthritic) horses prone to joint degeneration, yet lack conclusive scientific support.

Objectives: To quantify the effects of an oral joint supplement (combination glucosamine hydrochloride (GHCL), chondroitin sulphate (CS) and N-acetyl-D-glucosamine) in vivo on stride parameters of veteran horses.
