Yes. On the label, different brands may appear to be the same, but unlike drugs, the ingredients in supplements are not equivalent. Cosequin, with its exclusive combination of high purity glucosamine, low molecular weight chondroitin sulfate and manganese ascorbate, is the only glucosamine/chondroitin sulfate supplement that has been shown safe, effective, and bioavailable in peer-reviewed, published, controlled, U.S. veterinary studies. Chondroitin sulfate is a large molecule that is difficult to absorb. Low molecular weight means the particle size of the molecule is smaller and more easily absorbed by the digestive system than other less pure forms of chondroitin sulfate. While the low molecular weight chondroitin sulfate is more expensive, it is supported by published, controlled U.S. clinical studies for efficacy, safety and absorption. Cosequin is manufactured in the United States by Nutramax Laboratories, Inc. following manufacturing standards adopted by the pharmaceutical industry. Each batch of Cosequin is subjected to stringent quality control measures and meets label claim. However, a number of reports including a study published in the Journal of the American Nutraceutical Association showed that up to approximately 80% of glucosamine/chondroitin sulfate brands did not meet their own label claim.
