Summary
This research paper is a systematic review investigating the effectiveness of nutraceuticals, or natural health products, in alleviating the symptoms of osteoarthritis in cats, dogs, and horses. The study found low strength evidence supporting the efficacy of all nutraceuticals, except for omega-3 fatty acids in dogs.
Objective and Methodology
The study aimed to review available literature on the effects of nutraceuticals on symptoms such as pain and abnormal locomotion in pets with osteoarthritis. These pets include horses, dogs, and cats.
- The researchers systematically searched for controlled trials that evaluated the effects of nutraceuticals on pets with osteoarthritis, using databases like Medline, CAB Abstracts, and Google Scholar.
- The quality of scientific evidence was evaluated using criteria set by the Food and Drug Administration (FDA).
- They also adapted a scoring system from the CONsolidated Standards of Reporting Trials (CONSORT) statement and recommendations by the Center of Evidence Based Medicine of Oxford to assess the trials.
Results
The researchers studied 22 papers in total, with 5 studies on horses, 16 on dogs, and 1 on cats.
- The study found that there is low strength evidence for the effectiveness of all nutraceuticals, with the exception of omega-3 fatty acid in dogs.
- According to the research, there is a lack of rigorous randomized controlled trials and a low number of participants in clinical trials.
Conclusions
The study concludes that there is generally poor evidence to support the efficacy of nutraceuticals for osteoarthritis in pets, except for diets supplemented with omega-3 fatty acids in dogs.
- The study also advocates for better access to systematic reviews for future veterinary science objectives.
- The researchers suggest improving research reporting via internationally accepted criteria for standards and guidelines.
