Immune Support Supplements for Horses: Help Your Horse Stay Strong and Resilient | Emmers Equestrian
A strong immune system helps your horse stay healthy, perform well, and recover faster. Most of the time, a balanced diet with good forage gives the immune system what it needs. But there are moments when your horse’s defenses are under extra pressure: during travel and competitions, at the change of seasons, after an illness, in older horses, or when a horse moves to a new yard and meets new horses. In those moments, immune support supplements can help. At Emmers Equestrian, you’ll find immune support from brands such as Cavalor, Equine America, Global Medics, NAF, Foran, and Excellent.
Daily immune support
Products like Cavalor Resist + Vit C, Global Medics Immunotop, and Equine America Emune are designed to support the natural defenses of horses that need a little extra help. They’re popular for sport horses with a busy show calendar, horses that travel often, and older horses whose immune system may not be as strong as it used to be.
Vitamin C for horses
Horses can make their own vitamin C, but in some situations their own production may not keep up. Older horses, horses under stress from hard training or transport, and horses recovering from illness are common examples. Foran Vitamin C Pure provides a concentrated source of vitamin C, while Cavalor Resist combines it with other ingredients in one product.
Natural support: garlic and apple cider vinegar
Some horse owners prefer a natural approach. Excellent Horse Garlic Allicin Liquid is a classic choice, and garlic is also popular in summer for its strong smell that many owners use alongside their fly protection. NAF Apple Cider Vinegar is a traditional addition to the daily feed that many owners use to support general well-being and appetite. Always stick to the recommended dose, especially with garlic.
Liver support and specific needs
The liver plays a central role in processing nutrients and clearing waste products from the body. Equine America Liver Flush Solution is designed to support liver function, for example, after a period of intense work, medication, or a change in diet. For horses with specific challenges, Equine America Shaker Gard is formulated to support horses that show headshaking behavior.
The basics come first.
Supplements work best as part of good overall care. A balanced diet, plenty of forage and fresh water, regular exercise, a good vaccination and deworming plan, and clean, well-ventilated stables all help your horse’s immune system do its job. For horses that are sensitive to dust, combine immune support with our airways & respiratory supplements or a hay steamer.
A healthy gut also matters: much of the immune system is linked to the digestive tract, so check our digestive supplements as well.

Frequently asked questions
When does my horse need immune support?
Immune support can be useful during periods of extra pressure: travel and competitions, the change of seasons, a move to a new yard, recovery after illness, and in older horses. Healthy horses on a balanced diet often don’t need extra support all year round.
Can an immune supplement replace vaccinations?
No. Supplements support the immune system, but they don’t protect against specific diseases the way vaccines do. Always follow the vaccination and deworming plan your vet recommends.
Do horses need extra vitamin C?
Horses make their own vitamin C, so most healthy horses don’t need extra. Older horses, horses under stress or in hard work, and horses recovering from illness may benefit from a supplement. Ask your vet if you’re unsure.
Is garlic safe for horses?
In the recommended amounts, garlic supplements are widely used. Large amounts over a long time can be harmful, so always follow the dosing instructions on the product and don’t combine several garlic products.
What does apple cider vinegar do for horses?
Apple cider vinegar is a traditional feed addition that many owners use to support general wellbeing and appetite. Add it to the feed or drinking water according to the instructions on the bottle.
Are immune supplements allowed in competition?
Most immune supplements contain ingredients that are allowed, but always check the product information and the rules of your federation (for example, the FEI) before competing.
