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.

Best I've Found!

I prefer this over the more expensive or current fad supplements - side by side comparisons have left me feeling like this joint supplement has more bang for my buck. I have used the Formula 707 Joint 6 in 1 for more than 5 years as a preventative maintenance on the horses I ride regularly. I decided to give it to my husband's huge 17 hand spotted Tennessee Walking Horse on a whim. He's not ridden much just because my husband isn't that much of a rider. At the time King was 17 years old and had some hip pain and other aches. I started giving him this just because he is older and very large, I already had it on hand and it definitely wouldn't hurt. Within approximately two weeks he was acting like he was 10 years younger. He was running and bucking and acting like a huge fool!!! My barrel horses start on it when they start getting more ride time and I feel like it plays a huge part in keeping the joint aspect of their body feeling better longer. I don't like to run out of Joint 6 in 1 because I don't like riding my horses much if I know they haven't been getting it.

Loyal customer and believer

The supplements we use from 707 have proven to be beneficial as we care for our senior equine (28 & 30). Our vet is pleased with our horses health and well being, too! After all, they eat better than we do. ; )

This works better than any other joint supplement I've tried for my mare that has an arthritic bone spur in her fetlock..

Has worked wonders in my Wild mustang. He is not as jumpy since starting the 707

Quicker recovery!

I have certainly noticed a quicker recovery and more agile movement in my performance horses.


I love the auto ship feature, that way my horses never run out.
