Why Use Green Lipped Mussel?

Green Lipped Mussels (Perna canaliculus) are found off the coast of New Zealand. They've been found to have powerful benefits for joint inflammation in animals and humans alike. Green Lipped Mussel has only recently been used in equine supplements, and horse owners are seeing the benefits.


Why feed a joint supplement?

There's a common misconception that only arthritic, older horses can benefit from a joint supplement. That is far from the truth. In fact, feeding your younger horse a comprehensive joint supplement can help prevent or delay the onset of joint issues.

For older horses, or horses that are in rigorous training programs, feeding a joint supplement can help ease your horse's discomfort, and get them back to moving the way they should be.

  • Highly palatable

  • Manufactured in-house

Frequently Asked Questions

Is this product safe for horses that show in tested federations or race?

Yes, Joint 6-in-1 is safe for use leading up to and even during competition. The formula contains no banned substances.

I have a smaller than average/larger than average horse. How much should I feed?

Our standard serving size is for the average 1100 lb horse. This serving size can be safely adjusted up/down in proportion. For instance, a 500 lb pony would receive about a half a daily serving.

My horse won't eat most supplements. Will he eat this?

This product is alfalfa and wheat-midd based pellets. Most horses find it pretty yummy! For the occasional horse that is extra picky, we recommend mixing it with their grain, and starting out with a tiny serving. When we're talking tiny - we mean like 1 pellet. Gradually increase this over time. Usually that will work for most horses to get used to the taste.

If your horse absolutely refuses to eat the supplement, we do have a 90-day 100% satisfaction guarantee. Just reach out!

What is Green Lipped Mussel?

Green Lipped Mussel is a mussel found in New Zealand. It has been shown to significantly improve joint pain, stiffness, and mobility in both humans and animals.

How do I get free shipping?

Any order over $100 will ship for free! Orders less than $100 have a $10 shipping fee.

When should I expect to see results in my horse?

This varies per horse, as each horse is unique. We like to recommend 30 days on the product to start seeing full results. Many customers will double the dose for the first month, and then reduce it to a single serving per day, for most noticeable results. You can safely adjust servings up or down as needed.

What if I don't see the results I'm looking for?

We have a 90-day 100% satisfaction guarantee. Simply reach out to us and we will make things right!
