Our pledge of purity
The 30 fatty acids in every Mussel Dog pill is derived from sustainably harvested Green-Lipped Mussels that feed on the richest source of plankton in the world — the pure and pristine waters of Marlborough Sound in New Zealand.
Our Pledge of Purity means that the processing plant conforms to the highest quality control standards, which are strictly regulated by the MAF on behalf of the United States FDA and EU authorities to ensure the purest and most potent oil extract in the world (PCSO-524®). Plus, every step of the harvesting and manufacturing process in sanctioned and inspected regularly by the New Zealand government to assure that we meet or exceed their exacting standards.
Our Pledge of Purity also means that our ingredients have been lab tested for purity and potency and contain no mercury or toxins that are often found in many fish oil supplements and dog food containing fish oils. Mussel Dog is 100% safe with no known adverse side effects.
Mussel Dog is better than a fish oil in more ways than one.
Did you know that 60% of the fish oils tested by Consumer Labs were found to be of extremely poor quality and containing ingredients with less potency than those listed on the label? It’s true.
It’s also true that the fish used in many fish oil supplements may contain harmful contaminants such as mercury and other harmful substances such as PCBs and dioxins. These contaminants, and the poor quality of many over-the-counter fish oil supplements can be putting your dog’s health at risk.
Mussel Dog has no mercury in it, so we don’t have to take it out.
Fortunately, science has identified which fish have the lowest levels of contaminants and the highest levels of Omega-3 and Omega-6 fatty acids. Science also tells us that there is only one source in the world where the water is so pure and free of toxins like mercury.
A place where the plankton is so rich in nutrients, it produces the purest, most potent complex of 30 fatty acids found anywhere. That place is the pristine waters of Marlborough Sound in New Zealand — the place where the green-lipped mussel lives and where Mussel Dog derives its patented oil extract (known as PCSO-524®).
In short, Mussel Dog is sourced with mercury-free, pure ingredients and government-inspected to ensure 100% quality,100% purity, and most importantly, 100% safety for your dog.
Patented Oil Extract (known as PCSO-524®)
Mussel Dog’s multi-patented manufacturing process has allowed our company to produce the highest quality supplement of its kind in the world, using the most stringent standards of purity and freshness.
With a significant investment in research and development, Great HealthWorks has developed a natural and patented oil extract derived from green-lipped mussels known as PCSO-524®. A patented process that is able to identify and extract Mussel Dog’s active ingredient containing 30 fatty acids — a combination not found in any other supplement sold today.
