A randomized, double-blind, controlled study on the efficacy of an oral dietary supplement containing fish oil, ASU and phytotherapeutic extracts in canine osteoarthritis.
Our assessment
This study, published in 2025, tested an oral dietary supplement containing fish oil, ASU (avocado/soybean unsaponifiables), and phytotherapeutic extracts for dogs with osteoarthritis. It was a randomized, double-blind, controlled study, which is a strong design for testing cause and effect. The researchers specifically looked at how the supplement affected canine discomfort, lameness, and mobility.
Data not available on sample size or study duration. Because these details are missing, we cannot assess the strength or generalizability of the study's findings. For a reliable evaluation, we need to know how many dogs participated and how long they were followed.
How it works
Osteoarthritis in dogs involves joint inflammation and pain, leading to lameness and reduced mobility. The supplement combines fish oil (known for its anti-inflammatory omega-3 fatty acids) with ASU and plant extracts, aiming to support joint health through a multimodal approach. What this means for you: if you have a dog with osteoarthritis, this supplement represents a potential additional tool in a broader management plan, but the exact benefit cannot be determined from the provided data.
Safety profile
Data not available on side effects or adverse events from this study. No FDA data on adverse event reports is provided for this specific supplement formulation. Because safety information is missing, it is not possible to assess the risk profile of this product from the data given.
Our recommendation
Based on the data provided, we cannot make a specific recommendation for this supplement. While the study design (randomized, double-blind, controlled) is scientifically rigorous, the missing details on sample size and duration are critical gaps. Do not rely on this single report. Always consult with a veterinarian before giving any supplement to your dog, especially for managing a chronic condition like osteoarthritis NIH ODS ↗.

Abstract
Osteoarthritis (OA) is a common musculoskeletal disorder in canines, characterized by discomfort, lameness, and reduced mobility. Because of the inconsistent efficacy of available treatments, and that a definitive resolution can be achieved only in a small number of cases, OA remains a major challenge in veterinary orthopedics. The current strategy is usually a multimodal approach involving systemic administration of anti-inflammatory drugs, intra-articular therapies, physiotherapy, dietary modi
