Abstract
Osteoarthritis is a common canine disease frequently treated with nutritional supplements that often lack independent verification of ingredients, active ingredient concentration, efficacy, or safety. Human supplements containing Boswellia serrata extracts (BSE) with high concentrations of active constituents 3-acetyl-11-keto-β-boswellic acid (AKBA) and 11-keto-β-boswellic acid (KBA) are bioavailable, safe, and efficacious in the alleviation of symptoms of naturally occurring osteoarthritis in people. Thus, oral AKBA and/or KBA supplementation could be a promising novel therapy for dogs with osteoarthritis. The primary objective of this study was to determine the concentrations of AKBA and KBA within six human and seven canine market formulations containing BSE administered to dogs, using a derivation of the previously validated high performance liquid chromatography (HPLC) method. The secondary objective was to compare measured concentrations to label claims. The mean concentrations of AKBA and KBA within the formulations tested were 42.3 mg/g AF (0.1-155.7 mg/g AF) and 5.2 mg/g AF (0-24.8 mg/g AF), respectively, with four of the formulations containing an undetectable amount of KBA. None of the market formulations had a label...Continue Reading
