Why does your horse get stressed?

Horses are flight animals with an extremely sensitive nervous system. Competitions, transport, a new stable, changing group composition or unfamiliar environments are common stress factors. Even subtle changes in the daily routine can cause tension.

Chronic stress has direct consequences for your horse's health and performance. A magnesium deficiency amplifies this effect: magnesium plays a central role in nerve-muscle signal transmission. With a deficiency, your horse reacts faster, more intensely and stays tense longer. Recognisable signs include nervousness, excessive sweating, loss of focus and spooking.

My horse was always tense at competitions. Since ZEN he is much calmer during warm-up and I can ride him better. No drowsiness, just focus.

Frequently asked questions about calming horses

How quickly does ZEN work on a stressed horse?
With daily use you will notice a difference after 5 to 7 days. For acute stressful moments we advise starting with an increased dosage 3 days in advance. ZEN is not a sedative and does not work immediately.
Is ZEN doping-free and safe for competitions?
Yes. ZEN contains only magnesium and natural aromatic substances. Every batch is tested by an FEI-approved laboratory. You can use ZEN without risk before and during competitions.
Does ZEN make my horse sluggish or drowsy?
No. ZEN supports natural relaxation through magnesium. It is not a sedative. Your horse remains alert and ready to perform, but reacts less intensely to stimuli.
Can I combine ZEN with other Horse Tonic supplements?
Yes. ZEN works well with Tonic (general health) and PH (stomach protection). Many riders combine ZEN with PH, as stress and stomach problems often go together.
