VITEX AGNUS CASTUS POWDER – Equine calmer for moody aggressive mares, geldings and stallions.



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

Fine ground Powder.

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 fine powder 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.

As a guide one x 30ml scoop = 15g approximately.

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

    Fantastic product…. Amazing service…

    Since starting my mare on this product, she has honestly been a different animal. She’s so much more chilled, less argumentative and generally much more balanced – I know what I’m going to get each day now! I feed her this along with Pro-Earth Brewers Yeast and it seems to work wonders, both in terms of mood, rideability and condition. One very happy customer!

    I didn’t really notice anything majorly different when using this supplement. My mare is not aggressive bit seems to struggle when in season…. Our poor geldings are expected to perform and they really don’t know how to deal with her! I thought this supplement might reduce the strength of her season but I didn’t see any change. I’m going to try it again next Spring if she’s bad again.

    This is a great quality product and good value. Unfortunately the courier damaged the box and contents quite substantially but Progressive Earth replaced the damaged product very quickly. Great customer service.

    This changed my mare from being an argumentative stroppy mustang into a more normal happy appy! This has saved my sanity.
