Comparing Joint Supplements for Horses

If you browse through any horse supply catalogue, you’re likely to notice the dozens of joint supplements available.  Some are very pricey, and others, fairly reasonable.  But do they work?  And which ones are best?  It can be a tricky endeavor trying to find just the right one for your horse.

Some people may tell you that you are wasting your money if you buy any joint supplement at all. . . but I beg to differ.  I’ve read enough research and have had enough personal experience with oral joint supplements to know that some do, indeed, work.

Joint supplements can be beneficial for younger horses in training or competition as many can help prevent or slow down the rate of joint damage.  They can also be helpful for your older horses with mild to moderate osteoarthritis.

When comparing joint supplements for horses, the key is knowing which ingredients to look for and the ingredient amounts which are effective.  So here is a rundown on a few common joint supplement ingredients for horses as well as a few recommended products.

Glucosamine  and Chondroitin

Glucosamine is probably the most well-known and most proven joint supplement ingredient.   A type of sugar (glucose) molecule naturally occurring in joint cartilage, glucosamine has a high absorption rate and can protect against bone destruction.   Studies have also shown that glucosamine can slow down the rate of wear on existing cartilage and even help repair damaged cartilage.  There are two forms of glucosamine:  sulfate and hydrochloride, and both have proven to be effective.

Chondroitin is another component of cartilage (as well as bone and some connective tissues) that is also commonly used in joint supplements.  Glucosamine and chondroitin are often combined in supplements, and they seem to work best when used together.  Dr. Kellon VMD, author of Horse Journal: Guide to Equine Supplements and Nutraceuticals, suggests (for a 500 kg horse) starting with 6,000 to 10,000 milligrams (mg) of glucosamine, with the higher dosage recommended for working horses and during the first week for any horse (loading dose).  She recommends 1,250 to 5,000 mg chondroitin.

Many glucosamine/ chondroitin products for horses include a few other ingredients–I will list a few recommended products further down. . .

Hyaluronic Acid

Hyaluronic Acid, commonly called HA, is one of the newer oral joint supplements on the market. Like glucosamine and chondroitin, HA is also naturally occurring within cartilage and joint fluid.  If your horse has acute inflammation in his joints, HA may be the best way to go.  With HA, the higher molecular -weight products (often more expensive) work better than the less expensive, lower molecular-weight products.  The recommended dose for HA is usually 100 mg/day, but this dosage can be increased for severely inflamed joints.

I recommend: Conquer Gel:  One 60 mL tube provides 100 mg of HA per 10 mL (6 doses)  $10.85



Methylsulfonylmethane, a derivative of DMSO, is another naturally occurring compound which has shown to be beneficial for joints.  MSM is a great source of dietary sulfur, a mineral involved in the health and maintenance of collagen, cartilage, hooves, and hair, as well as joint fluid and many important enzymes.  MSM also provides significant anti-inflammatory and pain-killing effects for horses in hard work, as evidenced in this study-based article.  Recommended dosages for MSM vary, so you may have to experiment with it a bit to see what works best for your horse.

I recommend: Animed Pure MSM 1 lb. for $9.47


Devil’s Claw

Devil’s Claw

Devil’s Claw is known as the ‘herbal bute’–it’s well known for it’s analgesic and anti-inflammatory properties.   Devil’s Claw is often added to other joint supplements, but it can also be used alone.  Personally, I’ve used Devil’s Claw with soft tissue injuries in my horses and found it was quite beneficial.  If a horse had mild arthritis, I might use it (alone) for that as well.  The recommended dose for Devil’s Claw is 2,500 mg per day.




Yucca is another popular herbal anti-inflammatory which as been used for many years by Native Americans and more recently, the nutraceutical industry, for its anti-arthritic effects.  Like Devil’s Claw, it can be used alone or as an added ingredient to another joint supplement.

The recommended dose for yucca is 3,000 mg/day of the 10% saponin powder or 15,000 mg/day of 2% saponin powder.




Boswellia is a botanical medicine derived from the resin of the  Boswellia tree.  Clinical studies (in humans and dogs) have shown  boswelia to also be effective in reducing the symptoms of arthritis.  It is also believed to help support the health of connective tissues.  If given alone, 500 mg/day is the recommended dose for Boswellia extract.

Here is an herbal combination that I’ve used before and would recommend:

DC-Y Devil’s Claw/ Yucca Blend: 2,500 mg Yucca, 2,097 mg Devil’s Claw, 1,700 mg Grape Seed Meal, 500 mg Boswellia, 280 Cat’s Claw Herb, 168 mg Turmeric, 112 mg Feverfew, 112 White Willow Bark $31.00 


Other Beneficial Joint Supplement Ingredients

There are a number of other herbs, vitamins, and minerals that are beneficial for joints.  Here are a few of the more common ones you’ll see in joint supplements:

  • zinc
  • copper
  • manganese
  • vitamin C
  • turmeric


Combination Joint Supplements

Many equine joint supplements on the market are combination products with several different ingredients.   These may be the most effective supplements, but they are often the most expensive as well.  Before purchasing a combination joint supplement, you may want to try a single-ingredient (or just glucosamine/ chondroitin) joint supplement to see if that works for your horse.  However, if you don’t mind spending some money, here are some that I would recommend:

Chondrogen EQ: 5000 mg glucosamine sulfate, 500 mg chondroitin sulfate, 20 mg HA, and 20 mg manganese sulfate. 75 oz.  $134.50

Lube All Plus: 64 oz. liquid supplement containing 100 mg sodium hyaluronate/oz, 4,000 mg MSM, 2,500 mg glucosamine sulfate, and 400 mg chondroitin sulfate. (64 doses)  $174.95. (Smaller bottles are available from their website, but the 64 oz. from Amazon is the best deal I found.)

HylaRx Complete:  7,500 mg glucosamine, 5,000 mg MSM, 500 mg chondroitin sulfate, 100 mg hyaluronic acid and rice bran. 5 lbs.  $81.24

Grand Flex: 5,000 glucosamine HCL, 5,000 mg Vitamin C, 3,000 mg methionine, 250 mg manganese, 200 mg lysine, 200 mg zinc, 150 mg vitamin B, 100 mg bioflavonoids, 80 mg proline, 50 mg copper.  1.9 lbs. $39.99


Cautions with Joint Supplements

Some joint supplement ingredients such as glucosamine, yucca, and MSM can worsen symptoms of insulin resistance, equine metabolic syndrome, or Cushing’s disease in horses.  I would use extreme caution (work with your vet) or avoid these ingredients in these cases.

    My young mare was just diagnosed with arthritis in her back hocks I need as much help as possible on what and how to help her. The vet is going to do injections sigh but what to find other solutions for her any supplements or any natural ways. I have ordered Chia seed to start giving her is there anything else you can recommend that has been proven to work she is only 6, beautiful breeding,disposition and a unique color to boot. I was going to start her in Working Cowhorse Ranch Pleasure, we do team penning and sorting right now and because of her Blue Valentine/ Hancock bloodlines she is one that always wants a job to do. Thank you so very much. Dina C.

    Hi, can you help? I am devastated that my lovely 6 year old horse has been diagnosed with OA. They think it is due to his confirmation with slightly turned in hocks. He had starting training for dressage so I could compete and he loved learning but this has crept up on him/us. He has been medicated in his hocks along with Carprofen and he is looking much much better and able to hack out and work with controlled exercise, the usual drill but if I can help him more I would love too and try and delay the onset of this horrible disease. I am so confused with all the supplementsremedies, especially as he is so young and worry about side effects and other issues. What do you suggest for him, I have ordered Devils Claw but confused with other help! Thanks in advance 🙂

      Hi Cheryl,

      I’m sorry to hear about your horse. I would recommend looking into turmeric. Glucosamine and chondroitin are a couple other options. It’s definitely not the norm that he would be developing OA at such a young age and he may not be ‘cut out’ for intensive training/ showing. But you’re right in the fact that he likely needs a supplement to help combat this. Best of luck to you both!

    Hi Casie,

    Ha, me again. Bekah.

    So my 17 H Gelding Paint came to me with a few existing issues, joints is one of them as I was told by the guy who sold me him. He’s actually my vary first trainer, he had this horse for 7 years, only the last year he notice this horse develop joint issues and didn’t ride him for a year. According to people you suppose to wait 1 full year before any medication would take effect on the horse. He used this horse for Mounted shooting, barrel racing, round penning, you name it this horse did it all. Participated in street halloween festivals, trail ride galore! He was on the famous “Cosequin” supplement. I don’t believe in chemically enhanced supplements or even chemically mass production of horse feeds or animals in general.

    I took him off the Cosequin and put him on Joint Health Formular from It was on Ausgut 2015 I made the switch. I was told that any new supplements you change, would have to wait a year before fully taking effect on the horse’s joints. I ask the question to if that so, if I had to wait a year to ride him, and they replied, “No, not necessary”, that this supplement would work for him immediately. It is an all natural organic product with few ingredients and with the main ingredients needed for the joints.

    The following year during spring time, we had 3 weeks of down poor, I knew then I would not be able to ride him as one of the other issue he had was abscess, excessive abscess. Any day that it rain and I couldn’t ride him for weeks because of it However, here is the twist. After 3 weeks once the rain stopped, I notice not one abscess he contracted, just something minor but it was already heeling, he had no problems galloping. That is when I realized that his abscess had cured with the same joint health formula I was giving him. I didn’t change anything about his diet nor did I add anything to his diet, only the joint healthy formula that was suppose to only work for his joints. But not only did it work for his joints, it completely heeled his issue with abscess. I never had a problem ridding him after starting with the Joint Health formula. It does cost 130 for a 5 lb bucket, but lasts me about 3 months. Some people that had their horses at the same stable, had their horse out, and my Paint was doing maneuvers the’d never seen a horse do before, some sharp turn without loosing his position. We had to end up separating the 2 of them because he would catch up to the other horse and bit her and wouldn’t leave her alone.

    I testify that the joint health formula from I have my horse on, is by far The best supplement for joints and now abscess, out there, in my opinion.

    I wish I could give him regular vitamins, such as Chia seeds, flaxseeds stuff like this instead of a supplement. Right now he currently on Flaxseeds, Joint Health Formula, Garlic, Copra Cool-stance and DE. My mare is also on the same regime except for the joint health formulae which sometimes she ends up getting some because my horses always tend to switch buckets every now and again, and even that has not made any changes in him as for a joints goes or abscess.

    With this said, the guy who sold me him, think he won’t be able to compete anymore because of his joints or do the moves he can do with his body type, in fact this horse acts like a yearling. He has so much energy, he is playful with my mare, he’s a different horse, words cannot describe how he must be feeling, A completely new horse, I might add.Oh and I should add, he’s 13 years old.
