Vitex Agnus Castus (Also known as Chaste tree berries or ‘Monk’s pepper’).

Whole Berries.

No Fillers – 100% Pure Vitex Agnus Castus Berries.

Vitex Agnus Castus is well known for helping maintain a balanced hormonal system in mares, geldings and stallions.  It has been known to radically affect the mood in mares who exhibit unpredictable, stroppy and aggressive behaviour during hormonal cycles as well as to reduce aggressiveness in stallions and riggy geldings.

Vitex Agnus Castus can also support a healthy metabolic function by supporting the horse’s endocrine system.

Can provide support for:

  • The hormonal system.
  • Riggy geldings.
  • Hormonal moody mares.
  • Healthy metabolic function, especially in older horses.
  • Older horses who fail to shed their coats or drink excessively.

Feeding guidelines:

For moody and/or aggressive behaviour in mares, geldings & stallions and a healthy hormonal system, a suggested intake is 15- 30 g of Vitex Agnus Castus berries per day for a horse or pony.

Or for healthy metabolic function and normal coat shedding, a suggested intake is 20-30 g daily for an average 300 Kg pony, and  30-50 g daily for an average 500 Kg horse.

Please Note: Do not feed to pregnant mares or those due to conceive!
