What Supplement is Best For My Horse? A Guide to the Right Choice

Horse with supplements

As horse owners, we all want the same thing — a horse that feels good, looks healthy, and performs at their best. But with so many supplements on the market, figuring out which one your horse actually needs can feel overwhelming.

The truth is, every horse is unique. Some need extra digestive support, others struggle with mobility, while mares often benefit from calming hormonal balance. Choosing the right supplement can make all the difference to your horse’s comfort, behaviour, and long-term wellbeing.

Where to Begin? Take the Guesswork Out

If you’ve ever found yourself staring at shelves of supplements unsure what to pick, you’re not alone. That’s exactly why we created the Glas Equine Supplement Quiz — a quick, simple way to find out what your horse really needs.

👉 In under a minute, you’ll get a personalised recommendation based on your horse’s age, workload, and health priorities — whether that’s calmer behaviour, stronger joints, a shinier coat, or a supported immune system.

★★★★★ Megan Connell - Glas Equine Customer

“I started using the marshmallow root supplement on my thoroughbred who always has “sneezing/ blowing “ episodes this time of year end of winter to early spring (even though he’s got no allergies) since starting this he hasn’t done it once ! He’s also the grumpiest horse going and again his behaviour has even changed since starting this . Daily routines of brushing and tacking up was always a struggle but he’s honestly a nicer horse since starting the marshamallow root . He’s most definitely happier in himself and he will remain on this supplement for good . Honestly love it and the change it has made my horse.”
