JSTTONIC *Organic herbal blend for horses - daily arthritic-ease, joint-nourishing, comfort-restoring
If your horse has arthritis - or you’ve been told they’re starting to show arthritic change - and they’re feeling stiffer, slower to warm up, or just not moving as freely, that’s usually when we look at JSTTonic.
" I cannot believe the difference in my mare since being on JST Tonic, she's so much freer in her movement and looks so much more comfortable and happy.” Jade S.
For many horses, arthritis isn’t something we fix - it’s something we manage day to day. And what we're often seeing isn’t just the joint itself, but the surrounding soft tissues tightening up and the whole system becoming less comfortable.
JSTTonic was originally formulated for exactly this type of horse - in fact, one of our own (our TB mare, Carmen, born with an inward twisting LF hoof/pastern) - where ongoing support for comfort, connective tissue, and freedom of movement had become part of daily life.

Overview
Arthritic change is rarely just about the joint itself.
What we often see here is a wider picture developing around it - surrounding muscles tightening, connective tissue losing elasticity, circulation slowing down, and the horse gradually becoming less comfortable in their movement overall.
That’s why JSTTonic was designed as a daily blend supporting the wider picture around joint stiffness and mobility.
Rather than focusing on the joint in isolation, it supports the surrounding structures that help horses stay comfortable and mobile over time - connective tissue, circulation, muscular ease, and metabolic housekeeping.
For many horses, it becomes the daily foundation that helps them keep moving well, age more comfortably, and continue enjoying life.
Is JSTTonic right for your horse - and what to do next
JSTTonic is a good fit when your horse is showing signs of arthritic stiffness – the kind that comes with wear, compensation, and time.
✔ Known arthritic or degenerative changes affecting movement
✔ Stiff when first moving off, especially after standing in
✔ Takes time to loosen up and move freely
✔ Movement feels shorter, tighter, or slightly uneven
✔ Your horse is comfortable once warmed up, but clearly not as free as before
✔ Older horses who are managing wear and tear but still active
✔ You’re thinking “they’re coping… but they’re definitely feeling it”
In short: if your horse is dealing with day-to-day arthritic stiffness and needs help staying comfortable and moving, JSTTonic is the blend that supports that ongoing ease.
How JSTTonic fits into your horse’s support plan
JSTTonic is designed as your daily foundation for horses managing arthritic stiffness and wear-and-tear changes.
For many horses, this becomes the steady, ongoing support that helps maintain comfort, mobility, and ease of movement day to day.
That said, many of our older or arthritic horses do best on a layered approach – a steady daily foundation, with additional support ready when needed.
For example, Carmen (Carol’s mare) is maintained on JSTTonic, JointReflexa, and DuoBute daily, with TriBute kept on hand for the occasional “field hoon” moment (she was beautifully bred for racing!) when she’s clearly enjoyed herself a little too much.
From there, support can be layered depending on what you’re seeing.
Building structural support
- JointReflexa – where deeper support for cartilage, collagen, and joint structures is needed alongside daily comfort
Layering comfort (as needed)
- DuoBute – for additional daily support where stiffness or discomfort is more noticeable
- TriBute – for short-term support during tougher days, flare-ups, or increased workload
This allows support to adapt around your horse – maintaining a steady baseline while responding to changes in comfort or movement.
Foundation support
Without a solid mineral foundation, even the best joint support can only go so far. Supporting your horse’s baseline nutrition with a forage-based mineral blend such as VitaComplete or EquiVita helps maintain connective tissue strength, recovery, and long-term mobility.
In short
Use JSTTonic as your daily foundation – layer JointReflexa for structural support, and bring in DuoBute or TriBute when extra comfort support is needed.

Composition glossary
Each herb in JSTTonic works to nourish connective tissue, ease stiffness, and gently support circulation and joint comfort.
- Avena sativa (Milky Oats) – A gentle restorative tonic rich in minerals and silica, traditionally used to ease tension and support recovery during long-term physical strain.
- Arctium lappa (Burdock Root) – A classic cleansing and nutritive herb supporting detoxification and circulation.
- Apium graveolens (Celery Seed) – Traditionally valued for supporting fluid balance and comfort in stiff or swollen joints, natural circulation and tissue mobility.
- Viburnum opulus (Cramp Bark) – A soothing antispasmodic herb that helps ease muscular tightness and soft-tissue tension.
- Taraxacum officinale (Dandelion) – A rich mineral liver tonic that helps reduce fluid stagnation and supports joint comfort.
- Eleutherococcus senticosus (Siberian Ginseng) – An adaptogenic tonic that helps maintain resilience under physical or environmental stress.
- Centella asiatica (Gotu Kola) – A connective-tissue trophorestorative, traditionally used to strengthen connective tissues.
- Crataegus monogyna (Hawthorn) – A renowned circulatory tonic supporting blood flow to muscles and joints.
- Urtica dioica (Nettle Leaf) – A mineral-rich nutritive herb traditionally used to support circulation, fluid balance, and everyday joint comfort.
- Rosa canina (Rosehip) – A natural source of vitamin C and bioflavonoids, supporting collagen synthesis, joint strength, and immune health.

Fussy Eater?
Horses sometimes have their own opinions (and strong tastebuds!), so introduce gradually, building up over several days. See our Fussy Eaters guide for helpful tips if needed.

Energetic architecture - the synergy behind JSTTonic
JSTTonic is designed as a daily support blend for horses managing arthritic stiffness, wear-and-tear, and age-related changes in movement.
Rather than focusing on the joint alone, the formula supports the wider systems influencing comfort and mobility - connective tissue, circulation, muscle tone, and metabolic housekeeping.
Together, the herbs create a steady baseline of support that helps horses stay more comfortable, move more freely, and maintain ease of movement over time.
Think of it as the daily foundation layer for consistent, long-term support that keeps everything working as smoothly as possible.
Functional intent
JSTTonic is designed for horses experiencing arthritic changes, reduced fluidity of movement, or wear-and-tear changes, where comfort needs to be supported day to day.
It works across three key areas:
- connective tissue nourishment and resilience
- circulatory support to joints and surrounding tissues
- metabolic housekeeping of normal wear-related by-products
Functional categories – joint support in action
- Connective Tissue Nourishment & Structural Support - Centella asiatica, Rosa canina, Urtica dioica, Avena sativa
Supporting the health and resilience of cartilage, tendons, ligaments, and joint capsules. - Circulatory Support & Tissue Delivery - Crataegus monogyna, Apium graveolens
Eleutherococcus senticosus
Helping maintain healthy blood flow to joints and surrounding tissues, supporting nutrient delivery and overall comfort. - Muscular Ease & Soft Tissue Relaxation - Viburnum opulus, Avena sativa
Supporting the release of tension in surrounding soft tissues, which often contributes to stiffness and restricted movement. - Metabolic Clearance & Fluid Balance - Arctium lappa, Taraxacum officinale, Urtica dioica
Supporting the body’s natural processing of metabolic by-products associated with daily wear and tear. - Adaptive Resilience & Recovery - Eleutherococcus senticosus
Helping the system maintain energy, resilience, and recovery capacity in horses managing ongoing physical demand.
Big picture
JSTTonic is the steady, daily support that helps horses stay comfortable in their bodies - maintaining movement, easing stiffness, and supporting long-term mobility.
Used consistently, it helps create a more comfortable baseline, allowing other support (such as JointReflexa, DuoBute, or TriBute) to be layered in when needed.
