It’s not hard to find a pet supplement claiming to be “vet tested,” “clinically tested,” “clinically proven,” has “clinical results” or some other variation, but not all “clinical studies” are created equal. Survey studies: Some companies play fast and loose with their testing claims, while there was nothing “clinical” or “scientific” about their “study.” Many of these so-called tested supplements simply provided free product to a group of consumers and then asked them to complete a survey about their impressions of the products. This method is wrought with flaws. It is subjective. Responses can easily be influenced. This approach relies on solely on perception and not on any scientific measure. In vitro studies: Studies that are conducted “in vitro” are experiments conducted in test tubes or petri dishes — not in an animal. Based on the results from these tests, conclusions are drawn about the performance of the supplement within a living animal. Alternatively, studies conducted with living animals are known as “in vivo.” Non-species-specific studies: A vast number of companies test product performance in animals other than what the supplement was intended for. In the pet industry, this means pet supplements may be tested on mice or humans, which does not offer concrete evidence of how the supplement will react when given to a dog or cat. Small population studies: Supplement study claims may be based on results seen in only one or a few pets. These studies are open to errors because they didn’t involve enough animals to represent the wider population of dogs and cats. An effective study should include, at a minimum, 30 animals. Scientifically sound but morally questionable studies: Unfortunately, some sound scientific practices involve crossing or blurring the line of what is humane and moral. One example is the use of Beagle dogs. These animals live in cages and are destroyed once testing has been completed. Another practice employed by a popular joint supplement involved utilizing homeless dogs who were injected with a painful chemical to create joint disorder. In Clover’s gold standard studies: In Clover utilizes only scientifically sound research to develop our world-class supplements. This extra level of care ensures the In Clover supplements you give your canine companion or feline friend have the highest probability of success. Just one example of the research behind our products is the clinical study of our Connectin joint supplement. Connectin was clinically tested by a group of independent researchers at an internationally renowned veterinary university. The study population was comprised of more than 80 household pets who had been diagnosed with joint disorder by a veterinarian. To avoid any bias, the dogs were divided into two groups: one group received a daily placebo while the other group received Connectin daily. The animals’ mobility and comfort were measured using state-of-the-art force-plate analysis. A force place measures the amount of pressure applied to each limb. Stride length and reactions to palpation (touch) were also monitored. Using humane practices, measurable results and sound scientific methods, this gold-standard study illustrated that the pets who were given Connectin showed statistically significant improvements in mobility in an average of 15 days. While studies like these are certainly more labor and cost intensive than some other methods, we think your pet is worth it!
