Inflammation is at the root of many equine health conditions—from arthritis and soft tissue injuries to metabolic syndrome and laminitis. While NSAIDs like Bute or Equioxx are effective, long-term use can come with side effects like gastric ulcers or kidney strain.
That’s where natural anti-inflammatory supplements come in. They may not replace prescription medications, but they can support horses with chronic inflammation, especially when used under veterinary supervision. Below, we explore research-backed options including turmeric, omega-3 fatty acids, Boswellia, and Devil’s Claw.
This article is for informational purposes only. Always consult your veterinarian before starting any supplement, especially if your horse is on medication or has a chronic condition.
1. Turmeric
Turmeric, a bright yellow spice, is making its way into many horse feeding routines. The active ingredient, curcumin, has proven anti-inflammatory effects and is used in horses with arthritis, metabolic syndrome, laminitis, ulcers, skin irritations, among others .
Research says that the top benefits from feeding turmeric to your horses are:
- Beneficial anti-inflammatory properties
- Metabolic health (supports insulin sensitivity)
- Plays a role in protecting cartilage integrity.
- Helps lessen ulceration severity
- Improves recovery and enhaces training by reducing inflammation
Curcumin is tricky for the body to absorb. Mixing turmeric with fresh ground black pepper (about six turns on a hind grind dispense) and/or 15 ml oil source (like flaxseed oil) improves its uptake. I always start with a small amount, usually just a teaspoon, but a dose up to 2.4 g per day of turmeric is suggested as safe.
Tips for Using Turmeric
- Start slow, adding about a teaspoon to the feed and slowly increasing if your horse tolerates it up to 2.4g per day.
- Add 15 ml linseed oil and 1/2 teaspoon black pepper for better absorption.
- Watch for digestive sensitivity and stop if you see loose manure or signs of discomfort. Although it was initially thought to cause gastric irriation, this theory has been disproven.
If you don’t feel like buying the turmeric, linseed oil and black pepper and preparing it for your horse, then here are some products that contain turmeric for you to enjoy:

2. Omega-3 Fatty Acids
Omega 3 fatty acids, found in oils like fish oil and flaxseed oil, offer natural support against inflammation. These good fats help balance the body’s inflammatory response and are used by many owners to help with:
- conditions like arthritis, skin allergies, or even muscle soreness.
- hearth health and brain function
- cool calories for exercising horses and hard keepers
I’ve seen clear results when supplementing older horses with stiff joints; movement gets easier, and discomfort after work is less obvious. I normally supplement fish oil to every horse I compete, since it has been proven to lower the Omega 6 fatty acids in horses, which may contribute to health problems like inflammation if the ratio is incorrect.
Fish oil offers EPA and DHA, while flaxseed oil provides ALA. Both types help, but fish oil works more directly because horses convert ALA less efficiently, additionally flaxseed oil can degrade much quicker, needing special care for storing the product.
What to look out for?
It is important for you to check that the omega 6 and omega 3 balance is correct, many “fish oil products” actually contain a significant proportion of soybean oil, which is higher in omega-6 fatty acids; excessive omega-6 intake may promote inflammation
Let me show you some products:

- Check with your vet if your horse is on other medications or a special diet.
3. Boswellia Serrata
Boswellia, an herbal extract from the resin of the Boswellia Serrata Tree, is used globally to manage joint and muscle discomfort. Boswellic acids, its active compounds, are believed to limit the enzymes behind swelling and pain. Many equine joint supplements include Boswellia because it’s gentle on the stomach and unlikely to cause side effects seen with some medications.
I give Platinum Performace CJ, that has boswellia content included as part of the formula. It is a very recommended and highly reviewed product that my vet always asks me to give my showjumpers, specially the ones that are going to be competing frequently and high.
Let me show you products that use Boswellia Serrata:

4. Devil’s Claw
Devil’s Claw is a South African plant with a reputation for helping horses with chronic stiffness, joint pain, or even mild laminitis. The active compounds, called harpagosides, are linked to a reduction in discomfort from everyday wear and tear or old injuries.
Many horses respond quickly to Devil’s Claw, especially those with mild arthritis. It shouldn’t be given to pregnant mares, horses with gastric ulcers, or those on blood thinners without a vet’s approval.
🚨 Important Note:
Devil’s Claw is prohibited in FEI/USEF competitions due to its COX-inhibitory (NSAID-like) action. Always observe appropriate withdrawal times if your horse competes.
To Remember
- Follow the feeding instructions and weigh out each portion for accuracy.
- Stop use at least 72 hours before competitions if you show under organizations that restrict its use.
- Always talk to your veterinarian before starting Devil’s Claw in horses with ulcers or metabolic issues.

6. MSM (Methylsulfonylmethan): Sulfur Based Support for Tissues
MSM is a naturally occurring sulfur found in plants and animals, and is known for helping muscles, tendons, and joints recover from exercise. This supplement is often used for horses with:
- Osteoarthritis and degenerative joint disease
- Muscle soreness and exercise recovery
- Allergic skin conditions
- Laminitis and hoof health (via collagen and keratin synthesis)
Horses deficient in sulfur may show signs such as joint pain, slow post-exercise recovery, or poor hoof quality—conditions often linked to inflammation or tissue degeneration. It’s considered one of the safest equine supplements, with no reported toxicity. Because of its short half-life, any excess MSM is quickly excreted in the urine and feces.
MSM supplementation can be especially helpful for horses with arthritis, aging joints, or compromised hoof health. Research in humans suggests it may also slow cartilage breakdown, potentially delaying the progression of arthritis. For performance horses, MSM is commonly used to reduce inflammation and oxidative stress, helping muscles recover more efficiently after intense work.
I don’t supplement MSM separately for my horses because it’s already one of the key ingredients in Platinum CJ. That said, I’ve used pure MSM in the past—like Uckele’s MSM Powder—and saw great results. It was easy to mix into their feed, but I found it too inconvenient to manage separate supplements for my competition horses. Most owners report noticeably smoother movement and improved flexibility after a few weeks of consistent use.

7. Arnica: Tropical Support for Acute Swelling
Arnica montana is well known for use in topical gels or sprays for acute injuries. Think bumps, bruises, or sore muscles. While it’s not something I feed, I keep arnica gel in my tack room for after strenuous rides or minor knocks, and I’ve noticed it helps reduce swelling and speed up surface recovery time. Always check the skin for any broken areas, since arnica shouldn’t go on wounds.
Applying arnica is easy; simply follow the instructions on the label, massage gently into the sore area, and track your horse’s response. I’ve also talked with professionals who say that while arnica works externally, it helps your horse feel more comfortable after an intense day.
How to Choose the Right Supplement for Your Horse
Choosing the right supplement really comes down to your horse’s age, workload, and specific needs. But before I add anything to their diet, I always start by making sure the base diet is balanced—that’s one of the most common mistakes I see. Many people turn to supplements hoping for a quick fix, when in reality, the issue often stems from a deficiency in the core diet. In those cases, you’re just spending more money to compensate for something that should have been corrected at the foundation.
Once I’m confident the diet is balanced, I get clear on my goal. Am I trying to improve coat quality? Support joints and muscles ahead of more intense training? That focus helps guide my decision. I also always consult my vet before starting anything new and introduce one new ingredient at a time, over a week or two. That way, I can monitor for any side effects or sensitivities early on and make informed adjustments if needed.
- Check for third party testing to confirm quality and avoid hidden contaminants.
- Stick to one change at a time, so you can attribute any improvements or side effects to the right source.
- Consult with a vet, especially when dealing with chronic health problems or performance horses subject to competition rules.
- Look at your feeding program as a whole, and consider what might be missing in your horse’s nutrition that is causing or contributing to inflammation.
It’s a good idea to keep a simple journal of what you add or remove from your horse’s program, and note any observable changes or patterns. This extra step really helps you track down what works best for your horse.
