Why ZEN Works Without Sedation

Many calming products work by sedating the horse. useful for the handler, bad for performance. ZEN uses magnesium chloride and magnesium citrate, which support the nervous system's natural regulation without suppressing alertness or coordination.

Magnesium is one of the most depleted minerals in performance horses. High training loads, travel stress, and competition pressure all burn through magnesium reserves rapidly. ZEN replenishes these stores, reducing the excitability that comes from deficiency.

The liquid format means faster uptake. particularly important on competition days when you need results in hours, not days. ZEN can be given the morning before a stressful event or used as a daily maintenance supplement.

ZEN vs Other Calming Supplements

Products like Cavalor Calm and Equistro Sedalpin use herbal blends that can have variable effects. ZEN uses precisely dosed magnesium in a liquid form. a mineral your horse actually needs, not a herbal sedative. And unlike valerian-based products, ZEN is completely safe for FEI competitions.

Horse Calming Supplement. FAQ

What is the best calming supplement for horses?
For competition horses, a magnesium-based calming supplement without valerian or herbal sedatives is the safest choice. ZEN from Horse Tonic uses dual magnesium (chloride + citrate) in liquid form and is FEI doping-tested safe.
Will a calming supplement make my horse sleepy?
ZEN will not make your horse sleepy or uncoordinated. It works by replenishing magnesium, which helps the nervous system regulate naturally. Horses typically become calmer and more focused rather than drowsy.
Can I use ZEN at FEI competitions?
Yes. ZEN is independently tested for FEI-prohibited substances. It contains no valerian (which is banned in FEI competition) and is safe at all levels of regulated competition.
How quickly does a calming supplement work for horses?
Liquid ZEN can show effects within 2-4 hours. For best results, start daily supplementation 2-3 weeks before a major competition to build up magnesium levels gradually.
How do I know if my horse needs a calming supplement?
Signs of magnesium deficiency in horses include muscle twitching, nervousness, spookiness, difficulty settling, and overreaction to stimuli. If your horse has these behaviours especially in stressful situations, a magnesium supplement like ZEN is worth trying.
