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.

Gail S.

My 26 year old gelding has shown so much improvement in his joints. I recommend this product.

Teresa Wort

My horse is an OTTB. He bowed his tendon. He also completely blew out his suspensory 5 1/2 yrs ago. I bought him. Then I bought him PRP with shockwave. I have had him on this supplement for 4 yrs. Today his leg has completely healed. He is training to be a show jumper. I also use the hoof formula. His hooves are strong & healthy. I love 707 products ! Several vets have checked him. None of them expected a full recovery. He also recently started on Bemer electro magnetic treatments. So we could tighten up the last of his superficial tendon separation. He has zero scar tissue ! On ultrasound there is no evidence of such a severe injury. He blew out his right front leg. He is now 400 lbs heavier & he has muscle everywhere. The 707 muscle builder helped with that too.
