Harnessing the power of Green Lipped Mussel

Green Lipped Mussels, or Perna canaliculus, are a unique species of mussel that are found exclusively off the coast of New Zealand. These mussels have a distinctive green shell and are well-known for their potential health benefits.

Scientific research has shown that Green Lipped Mussels contain a high concentration of omega-3 fatty acids, which are essential for maintaining joint health and reducing inflammation. These omega-3s are also known to support a healthy immune system, cardiovascular health, and brain function.


In particular, Green Lipped Mussels have been found to be effective in reducing joint inflammation and improving mobility in both animals and humans. This makes them an attractive option for individuals suffering from conditions such as osteoarthritis, rheumatoid arthritis, and other joint-related disorders.


In recent years, Green Lipped Mussel supplements have become increasingly popular among horse owners. Equine athletes are susceptible to joint issues and injuries, and traditional treatments can be costly and come with unwanted side effects. However, Green Lipped Mussel supplements have been shown to be a natural and safe alternative for supporting joint health and overall performance in horses. Formula 707 Joint 6-in-1 is the only option on the market that combines Green Lipped Mussel with 5 other standalone ingredients for joint health.
