The 11 Best Joint Supplements For Horses

Horses are quite enormous beasts. Many individuals weigh more than 1,200 pounds and are taller than six feet. The cumulative effect of a horse's numerous kilometers traveled while carrying all of that weight on its joints increases over time. Eventually, horses will have many of the same ailments as people, such as joint discomfort, arthritis, and more.

One of the best ways to keep your horse from getting these diseases is to put chemicals in its food that help keep its joints healthy.

Numerous supplements on the market include multiple of these ingredients for joint health, making it simple to keep your horse's joints in excellent condition. The only thing left to do is choose which joint supplement to use, which might be more challenging than you might expect.

Don't worry; we are here to assist you. In the following evaluations, BestForPets (bestforpets.org) compares the best joint supplements for horses. This should expedite the process of selecting one for your horse, as all of the pertinent information is included in this post.


Horse joint supplement LubriSyn HA Hyaluronic Acid – Best Overall



LubriSyn HA Horse Joint Supplement is our preferred joint supplement for horses. It is composed of hyaluronan, which can help decrease inflammation, prevent rheumatoid arthritis, and provide tissue protection.

Overall, this indicates that it will aid in keeping your horse’s joints pain-free and performing at a much higher level. As your horse’s movement increases as a result of a reduction in pain, you will observe rapid improvement.

The majority of identical joint supplements are difficult to give, which is a concern we’ve noticed. However, LubrisSyn HA is clear and tasteless, which makes feeding a horse considerably simpler.

When you put it on their meal or squeeze it into their mouth, your horse will not detect an unpleasant flavor.

This supplement is also an excellent option for horse owners with several animals.

It might be difficult to provide adequate supplements for numerous horses, but LubriSyn HA Horse Joint Supplement is available in up to a gallon-sized container, which should last a considerable amount of time even when supplementing multiple horses.

Granted, it is more expensive than alternatives, but it does function.


  • Available in quantities as large as a gallon
  • Tasteless and tasteless
  • Made with hyaluronan
  • Reduces ache
  • Enhances mobility


  • It’s rather expensive


AniMed Glucosamine Horse Supplement – Best Price



Maintaining the health of your horse’s joints may be difficult and costly. The AniMed Glucosamine Joint Support Horse Supplement is far more cheaply priced than the majority of joint supplements for horses.

It comes in a 2.25-pound tub and offers a 70-day supply at an extremely reasonable price.

Despite its inexpensive cost, this supplement is filled with effective ingredients. It has an astounding 20 grams of omega-3 per serving.

Each meal also includes 5,000 milligrams of glucosamine, which has been found to reduce pain and inflammation as well as provide arthritic relief.

This supplement utilizes the two most promising forms of glucosamine, glucosamine HCL and glucosamine sulfate. Glucosamine exists in a variety of forms.

Comparable to other similar supplements, AniMed is difficult to administer to your horse. It is a powder, and horses do not appear to enjoy its flavor.

It must be thoroughly mixed with your horse’s food in order for them to consume it, but once they do, it has shown to be a very effective supplement for improving joint health, which is why we consider it to be the most cost-effective joint supplement for horses.


  • Glucosamine HCL and sulfate are present
  • Rich in omega-3
  • Priced reasonably
  • 70 days of supplies in a single container


  • Not every horse like the flavor


Joint health supplement Nutramax Cosequin ASU – Premium Option



Occasionally, you receive what you paid for. Even if the price of the Nutramax Cosequin ASU Joint Health Supplement is exorbitant, it is a very effective joint supplement for horses that is packed with vital nutrients.

This supplement is able to maintain joint mobility, preserve cartilage, and improve overall joint health as a result of the high-quality joint health ingredients that it contains.

MSM and ASU are joint-health superstars included in this formulation. Obviously, they are not operating alone. The high dose of glucosamine per serving, which is somewhat more than 14,000 mg, has a synergistic impact on these dietary supplements.

Each tablet also contains 2400 milligrams of chondroitin sulfate, making this a powerful supplement for joint health.


  • Glucosamine and chondroitin are present
  • Developed using MSM and ASU
  • Defends cartilage
  • Supports joint mobility


  • Extremely expensive


Lab Acti Flex Joint Supplement by COX VETERINARY



The Acti Flex Joint Supplement functions by boosting the quantity of synovial fluid in your horse’s joints, allowing the joints to mend regions that are under to significant stress during running.

A combination of critical joint-support supplements, including hyaluronic acid, MSM, chondroitin sulfate, and glucosamine sulfate, is utilized for this purpose.

In contrast to many other supplements, this product contains substantial levels of each component, including 8,000 milligrams of glucosamine and 4,000 milligrams of chondroitin.

This pill performs an excellent job of lowering pain and inflammation, owing to the presence of all of these effective components. However, it must have a somewhat harsh flavor, as many horses appear to loathe it.

It is tough to persuade horses to consume this supplement, which you must do in order to observe its benefits. Nonetheless, if you can get your horse to drink it, this supplement is incredibly beneficial.


  • Contains hyaluronic acid
  • Contains many joint-health supplements
  • Decreases inflammation and reduces pain
  • Concentrated formulation


  • The flavor repels some horses


RICHDEL Joint Support for MSM



The RICHDEL MSM Powder Joint Support is wonderful for decreasing the discomfort and inflammation that afflict many horses’ joints.

It is available in huge buckets of up to 10 pounds. It is comprised of 99% pure MSM, which is a derivative of DMSO, a very powerful molecule that may significantly decrease inflammation and discomfort.

This MSM is crystalline and completely odorless and flavorless. Despite this, getting a horse to ingest it might still be difficult.

The flavor must not be very enticing. However, it works rapidly, so if you can convince your horse to consume it, you should see great results within a few days.


  • Competitive pricing
  • 99% MSM, a DMSO derivative
  • Tasteless and odorless
  • Works rapidly


  • Can be challenging to feed


Cetyl M Equine Joint Action Formula Supplement



The Cetyl M Equine Joint Action Formula is unreasonably pricey, in contrast to the majority of the supplements on our list. This would be more acceptable if it worked for all horses; nevertheless, some horses do not appear to benefit from this supplement.

Still, there is plenty to appreciate here. The apple taste of this supplement is pleasant to horses. This makes it rather easy to encourage a horse to eat, which cannot be stated for the majority of other supplements.

Additionally, we appreciate the inclusion of key chemicals for joint health, such as glucosamine and MSM.

However, the primary component is cetyl myristoleate, which has been found to lessen the pain and inflammation associated with arthritis, but research on this chemical is not nearly as thorough as research on other compounds known to promote joint health.

This supplement provides sufficient levels of each active component, however we would want to see more of the well-established ingredients.


  • Apple taste appeals to horses.
  • Contains several joint health supplements


  • Far more expensive than alternatives
  • Does not appear to benefit all horses


Rapidly Acting Manna Pro Rapid Flex Joint Supplement



Rapid Flex Fast-Acting Joint Supplement from Manna Pro comes in a four-pound bucket, but costs about twice as much as comparable supplements.

Nonetheless, it is a fast-acting medication that gives relief for swollen, painful joints. It is a natural combination comprised of nine distinct herbs and proven components.

Included among the established constituents are chondroitin sulfate, hyaluronic acid, and glucosamine HCL, which are essential to any joint-health supplement.

Like all vitamins, this one is ineffective if your horse refuses to use it. Manna Pro asserts that this supplement is incredibly appetizing, yet it appears that the majority of horses disagree.

However, it is simple to include into your horse’s grain, despite the fact that horses are not quite as fond of the anise flavor as Manna Pro would have you believe.


  • Natural mixture
  • Full with proven components


  • More expensive than some options
  • Horses don’t appear to enjoy it


Corta-Flx Equine Pellets Joint Flex Supplements



Because they are not a powder, these pellets are often easier to administer than other joint supplements. They combine nicely with food and do not appear to affect horses. In addition, they include a number of effective substances, including chondroitin and hyaluronic acid.

The issue is that there are insufficient quantities of each chemical to be effective. This product contains only 50 milligrams of hyaluronic acid and 1,000 milligrams of chondroitin.

Other supplements with comparable amounts and greater useable doses of the essential elements are available for around half the price of this one.

Therefore, why should you pay more money on Corta-Flx Equine Pellets? Unless those are the only ones your horse will consume, we cannot recommend them.


  • This product contains chondroitin and hyaluronic acid
  • Some mixtures are more difficult to feed than pellets


  • Very low concentrations of valuable substances
  • Overpriced relative to quantity


Majesty’s Flex Wafers Horse Supplement for Joint Support



The difficulty of administering the majority of the joint supplements we’ve tried on our horses has been a problem. Even if the supplement has no flavor or odor, it may be difficult to encourage your horse to consume it if it comes in liquid or powder form.

Majesty’s Flex Joint Support Wafers appeared to be an effective remedy. This dietary supplement comes in the shape of wafer treats that should be simple to provide to a horse.

These wafers are unfortunately more like globs. This makes it difficult for your horse to maintain the wafer in its mouth, and many horses will drop the treats while attempting to eat them.

Obviously, it appears that some of them intentionally dropped the wafers due to the roughness since they were no longer interested in attempting!

Nonetheless, these wafers are loaded with anti-inflammatory and range-of-motion-enhancing substances. Glucosamine, MSM, and chondroitin, the three most significant joint supplements, are included here. However, they might benefit from larger concentrations.


  • Wafers are simple to serve
  • Full of vitamins that improve joint health
  • Reduces inflammation and improves flexibility


  • Consuming difficulties for horses
  • It appears that horses dislike the texture
  • For a 1,200-pound animal, dosages are rather modest

Buyer's Guide

Choosing a joint supplement for your horse should be straightforward, or so it would appear. Find the supplement with the correct components, and you will be successful.

The only difficulty is determining which components to seek. This buyer’s guidance comes into play at this point. In it, we will provide an overview of the most essential and effective joint support ingredients that you should look for in any joint supplement for horses.

Major Joint Support Installations

There are a variety of substances and chemicals that may be present in a joint supplement. However, not every substance has been demonstrated to improve joint health.

But the following four substances are supported by science and may be relied upon for your horse’s and your own joint health.


Glucosamine is a substance found in the fluid that surrounds your joints. The majority of supplementary glucosamine is derived from shellfish, however it can also be manufactured.

Glucosamine can aid in slowing cartilage degradation. Additionally, it can help relieve pain and inflammation, especially those related with arthritis.


Chondroitin can give similar advantages as glucosamine and is present in cartilage. It aids in the reduction of inflammation and discomfort. Moreover, chondroitin can decrease the progression of joint and disk deterioration and alleviate the discomfort associated with arthritis.


People provide MSM to their pets for a range of conditions, including arthritis, bursitis, and rosacea. MSM’s efficacy in treating these conditions is not well supported, however it has been demonstrated to lessen arthritic pain and swelling.

MSM has also been reported to be useful against repeated stress injuries and to aid in accelerating exercise recovery.

Hyaluronic Acid

Hyaluronic acid is a naturally occurring substance that functions as a lubricant and cushion in joints and other tissues of the body. Numerous joint supplements for people and animals include it because it might alleviate arthritis-related pain and swelling.


Joint tonics for horses are not significantly different from those for dogs or people. Horse supplements frequently contain the same active chemicals and provide comparable pain relief, but in higher concentrations.

As you’ve seen in our evaluations, there are a multitude of possibilities to pick from, but we recommend only three.

Overall, our preferred hyaluronic acid horse joint supplement is LubriSyn HA. It is transparent and flavorless, making it simple to administer. In addition, it is available in bulk quantities up to a gallon. This formulation’s hyaluronan has an immediate and long-lasting impact on sore and inflamed joints.

AniMed Glucosamine 5000 Joint Support Powder is the most cost-effective option. You receive 2.25 pounds in the tub for a very low price, which will last you an additional 70 days. This formulation combines two forms of glucosamine and an abundance of omega-3 fatty acids to keep your horse’s joints pain- and inflammation-free.

Nutramax Cosequin ASU powder is our top recommendation. It preserves cartilage and enhances joint mobility by including high quantities of proven ingredients such as glucosamine, chondroitin, MSM, and ASU.
