" This product is easy to dose and it seems to be helping." Stuart T.
When horses start to feel a bit “not quite right” in their body, it can be a gradual loss of the small building blocks that keep everything holding together.
That’s where MSM tends to come in.
If you’re looking to support your horse’s joints, coat, or overall structural health, MSM is often one of the simplest places to start.
It provides a clean source of sulphur — a key building block the body uses for cartilage, connective tissue, and keratin, making it particularly useful during coat change, periods of work, or when supporting hoof and skin quality.
This is a straightforward, single-ingredient option that fits easily into most feeding plans, helping maintain structure and strength without complicating the diet.
You’ll also find MSM used alongside joint and respiratory support blends, where it plays a supporting role in maintaining tissue integrity and normal mucous membrane function.
It’s one of those dependable additions that many owners keep in the feed room year-round.
Overview
Whenever we start digging into coat quality, hoof strength, connective tissue, joint support, or even seasonal coat change, we keep bumping into the same nutrient - sulphur.
Completely different systems, completely different symptoms. Yet sulphur keeps showing up in the background.
That's because sulphur is used throughout the body as part of the structures that help hold everything together - from keratin in the coat and hooves, to connective tissue, collagen, and countless everyday cellular processes.
MSM provides a simple, highly bioavailable source of that sulphur.
Many owners add MSM as part of a broader nutritional programme supporting joints, connective tissue, coat quality, hoof integrity, and overall structural maintenance - particularly during periods of growth, work, ageing, or coat change, when demands on the body's building materials may increase.
MSM is also frequently included as part of respiratory support programmes, as sulphur contributes to the normal structure and function of mucous membranes.
In simple terms? MSM helps provide one of the basic building blocks the body relies on every day - quietly supporting the structures that help keep your horse holding together well.
How MSM fits into your horse's support plan
MSM is a good fit when you want to support the small structural building blocks that keep your horse holding together well – day to day, season to season.
✔ You’re looking to support connective tissue, cartilage, and overall structure
✔ Coat, hooves, or skin quality seems a little tired or slow to come through
✔ You’re heading into or through coat change and want to support keratin production
✔ You’re building a feeding plan and want to cover sulphur as a key nutrient
In short: if you want to support structure from the ground up – coat, connective tissue, and beyond, MSM is a simple, reliable place to start.
However, on its own, it’s just one piece of the picture. From there, support can be built out depending on what you’re seeing.
- Layering support
- Glucosamine sulphate – where additional support for cartilage and joint fluid is needed
- JointReflexa – for broader structural support, combining multiple nutrients to support joints, connective tissue, and muscular function
- Where MSM plays a supporting role
- BreathePlus or KoffTonic – as part of a wider respiratory support approach, where maintaining mucous membrane integrity and tissue resilience is important.
- LKLCARE – it’s interesting how often coat change is when things start to feel a bit ‘off’ — not always dramatic, but enough to notice, when the body is under increased pressure to process and clear seasonal metabolic load, and structural nutrients like sulphur are in higher demand.
In this context, MSM can be used on its own as a simple nutritional input, or alongside more targeted support where needed.
- Foundation support
Structural health relies on more than individual nutrients. Supporting your horse’s baseline nutrition with a forage-based mineral blend such as VitaComplete or EquiVita helps ensure key building blocks like sulphur can be properly utilised across the whole system.
In short
Use MSM as a foundational building block for structure – and layer more targeted support depending on which systems need extra attention.

Energetic architecture - the synergy behind MSM
Over the years we've learned that some horses don’t present with one clear issue. Not lame, or unwell - just not quite holding themselves together in the way they used to.
So we have to ask: is the body getting enough of the basic building blocks it relies on every day?
MSM is built around one of those building blocks - sulphur.
Think of it as helping the body maintain its internal “framework” - not changing how things work, but supporting what everything is built from.
Functional intent
MSM is designed to support structural integrity, connective tissue, and everyday cellular processes through the provision of bioavailable sulphur.
It works across three key areas:
- connective tissue and structural support
- keratin and coat integrity
- cellular sulphur availability
Functional categories – structural support in action
- Connective Tissue & Structural Integrity
- Supporting the formation and maintenance of connective tissue, including tendons, ligaments, and joint structures. - Keratin & Coat Support
- Supporting the production of keratin, contributing to coat, skin, and hoof quality. - Cellular Sulphur Availability
- Providing a readily available source of sulphur used in normal cellular processes and tissue maintenance.
Big picture
MSM is a simple nutrient with a surprisingly wide reach.
Wherever the body relies on sulphur-containing structures - connective tissue, keratin, collagen, and countless cellular processes - MSM has a role to play.
In simple terms: when the building blocks are in place, the structure tends to take care of itself.
Clinical considerations
Advisories
May be fed long-term as part of a structural or connective tissue support programme.
Contraindications
Pregnant or nursing mares: use under veterinary guidance due to limited data.
FAQs
Frequently Asked Questions
What is MSM?
MSM stands for Methyl Sulfonyl Methane, a naturally occurring organosulphur compound.
It provides a highly bioavailable source of sulphur, which the body uses in connective tissue, cartilage, keratin, collagen, and many everyday cellular processes.
Why is sulphur important for horses?
Sulphur is one of the body's key structural building blocks.
It is found throughout connective tissue, cartilage, tendons, ligaments, skin, coat, and hooves, and plays a role in many normal cellular functions.
That's why MSM often appears in feeding programmes aimed at supporting joints, structure, coat quality, and hoof integrity.
What is MSM commonly used for?
Many owners choose MSM as part of a nutritional programme supporting:
✔ Connective tissue and joint structure
✔ Coat quality and seasonal coat change
✔ Hoof integrity
✔ Tendons and ligaments
✔ General structural maintenance
It is often used as a simple, foundational nutrient that fits into a wide variety of support plans.
Can MSM be fed long term?
Yes. MSM is suitable for long-term daily use and is often fed year-round as part of a broader nutritional programme supporting structural health and connective tissue.
Is MSM suitable for older horses?
Absolutely. Many owners choose MSM for veteran horses as part of a long-term approach to supporting connective tissue, cartilage, coat quality, and overall structural maintenance as horses age.
What's the difference between MSM and glucosamine sulphate?
Although they are often fed together, they perform different roles.
Glucosamine sulphate primarily supports cartilage and joint fluid.
MSM provides sulphur, one of the body's key structural building blocks, which is used throughout connective tissue, keratin, collagen, and many other tissues.
In simple terms, glucosamine focuses more specifically on joints, whilst MSM has a wider structural role throughout the body.
Can MSM be fed alongside glucosamine sulphate?
Yes. This is one of the most common combinations used by horse owners.
Glucosamine sulphate supports cartilage and joint fluid, whilst MSM provides sulphur used throughout connective tissue and structural tissues.
What's the difference between MSM and JointReflexa?
MSM is a single nutrient providing a source of sulphur.
JointReflexa is a broader formulation that combines multiple nutrients selected to support joints, connective tissue, cartilage, muscular function, and structural resilience.
Many owners start with MSM when looking for simple nutritional support and move to JointReflexa when a more comprehensive approach is required.
Can MSM help during coat change?
Many owners choose MSM during spring and autumn coat change because sulphur is a key component of keratin, the structural protein found in hair and hooves.
Periods of coat change can place additional demands on the body's building materials, making MSM a popular addition at these times of year.
Can MSM be fed alongside respiratory support products?
Yes. MSM is often included alongside products such as BreathePlus or KoffTonic as part of a wider respiratory support programme.
Sulphur contributes to the normal structure and maintenance of tissues, including mucous membranes.
How quickly will I notice a difference?
Every horse is different.
Some owners notice changes quickly, whilst for others the benefits become more apparent over time as part of a consistent nutritional programme.
Because MSM works as a nutritional building block, it is generally best viewed as a long-term support nutrient rather than a quick fix.
Do I still need a mineral balancer if I'm feeding MSM?
Yes. MSM works best when the wider nutritional foundations are in place.
A forage-based mineral balancer such as VitaComplete or EquiVita helps provide the broader nutritional framework needed for healthy connective tissue, coat quality, hoof integrity, and everyday cellular function.
