Fluid Action® HA is our liquid joint health supplement that helps promote healthy joint function with glucosamine, sodium hyaluronate (HA), vitamin C, MSM, yucca, and gingko biloba. Fluid Action® HA provides 25mg per ounce of Sodium Hyaluronate (HA), the stable and orally absorbable molecular weight form of hyaluronic acid. HA is known to support and lubricate joints along with helping maintain joint structural integrity. See healthier joint function in your horse within 8 days.


Fluid Action® HA liquid contains functionally high levels of the most recognizable joint health ingredients like Glucosamine, 5000mg/oz, Vitamin C, 1000mg/oz, MSM, 60mg/oz, Yucca, 29mg/oz, Sodium Hyaluronate 25mg/oz, and Ginkgo Biloba, 18mg/oz. Fluid Action® HA also contains B vitamins and antioxidants to provide your horse with maximum support for healthy joints.

Glucosamine is a GAG (glycosaminoglycan). GAG’s are part of the structure of the matrix of cartilage, and cartilage is the covering of articular bone; which is extremely important for healthy joints.

Hyaluronic Acid is an important component of joint synovial fluid, which is the fluid that cushions and lubricates the joint.  Sodium Hyaluronate is the stable and orally absorbable form of hyaluronic acid, of the molecular weight studied most (1 million Daltons). Hyaluronic acid is known to support and lubricate joints, help to maintain structural integrity, and support healthy levels of joint synovial fluid.

MSM is a source of highly bioavailable sulfur. Several molecules needed by joints contain sulfur bonded to the molecule, so an adequate supply supports healthy joint tissue.

Joints are avascular, meaning there is no direct supply of blood. Cells within the cartilage rely on passive diffusion for their supply of nutrients. Ginkgo biloba is known to promote healthy circulation which can support this process in joint cells.

Fluid Action® HA has the following benefits for your horse:

  • Supports and lubricates the joints
  • Eases joint stiffness due to normal daily exercise and activity
  • Supports ingredient uptake for joint health
  • See results in as little as 8 days, guaranteed



For 1000 lb Horse: For the first 8 days, gives 2 fluid ounces daily. After 8 days give one fluid ounce daily thereafter.

    I had an old abused mare that I rescued. She was the best horse I have ever owned. I started her on this product and with good feed and time she got so much better. After a few months I took her off this product. I wanted to see if she needed it now that she had gained 100 pounds and was much healther. In just a short time she again had a hard time walking and was very uncomfortable . I put her right back on and she walked fine and was not uncomfortable and miserable anymore. It truly was a miracle for her, she stayed on it until she died at 30. I highly recommend this product.

    I love this stuff. I use it for both my horses and dogs. It’s keeps them moving comfortably and has other health benefits like a beautiful shiny coat!
    It was shipped quickly and arrived undamaged.

    I work with Great Dane Rescue, and this is our go to supplement for our foster great danes and many of us use it for our personal danes. First started using at the recommendation of Chap’s Feed Store in Livonia, MI. The difference of smooth and comfortable gait was observable within the first week of use. Great Product at a Great Price!

    The paper insert inside the cap popped out after a few days which was a bit messy but otherwise satisfied with the product.

    I purchased a yearling filly with a small lump on her knee. During a veterinary inspection, she rated a 1 of 5 on the lameness scale. X-Rays revealed a small bone spur, likely from some kind of impact as a youngster. My veterinarian recommended starting her on a high-quality joint supplement ASAP, so I began my search. I had used some of Finish Line’s other products before, like Air Power and Quia-Calm, with great success. Their joint supplement Fluid Action HA attracted me because of its all-natural ingredients, online availability and reasonable price. After feeding it for one year, I returned to the same veterinarian for a follow-up and the filly showed no signs of lameness on any of the tests. She turns 5 next year and still going strong – not one lame step. Highly recommend this product and this company. Keep expanding your product line – I want it all!! 🙂 🙂
