Horse Liver Health: Why Detox Matters More Than You Think

by Dr. Valerie De Clerck on Jul 13 2026

Elevated liver enzymes signal that something needs attention, but bloodwork trends across several markers, not a single high number, are what your vet uses to gauge severity. Moldy hay, contaminated grain, and certain pasture plants like ragwort are documented risk factors for equine liver stress. Milk thistle has real, equine-specific evidence for helping cortisol return to resting levels after exercise, alongside a broader track record in other species. Routine bloodwork after medication courses or illness, plus a seasonal liver support course, is a practical way to stay ahead of hepatic stress.
