Botanical supplements for nutritional support — not medicines, treatments, cures, or a replacement for veterinary care.
What is milk thistle?
Milk thistle is a botanical traditionally associated with liver support. It is commonly used in equine supplements aimed at general wellbeing, seasonal support and horses whose owners want to support normal liver function through nutrition.
Careful wording matters
It is important not to claim that milk thistle treats liver disease or detoxifies the body. A responsible guide should say that milk thistle may support normal liver function as part of a wider care routine. If there is any concern about the horse’s liver, blood tests and veterinary advice are needed.
When owners often consider it
Owners may look at milk thistle during seasonal changes, after periods of dietary change or as part of a general support routine. It is often paired with herbs such as dandelion, nettle or burdock root. The aim should be support, not correction of a diagnosed problem.
Cautions
Speak to a vet before feeding milk thistle to horses on medication, pregnant mares or horses with diagnosed liver or metabolic conditions. Keep supplement records and introduce gradually.
