Cavalor Venus is a herbal extract that supports the mare’s fertility cycle, helping to alleviate the effects of irregular ovulation. Hormonal fluctuations during their complex fertility cycle can make mares very restless and uncomfortable. Stubbornness and irritability, but also stiffness and other physical discomforts are characteristic of mares in oestrus.


The impact this has on sports performance and trust between rider and horse is not to be underestimated. Cavalor Venus doesn’t block their cycle, it just creates a more regular one. The more regular her cycle, the calmer and more pleasant your mare will be.


Venus is composed of several natural active ingredients that support the metabolism during the cycle, suppress characteristic (negative) behaviour during oestrus and provide overall relaxation for both mind and body. You’ll experience a totally different horse, one that feels better in her skin. 

Venus has always also been known to have a postive effect on stallion hormones.

  • Key Ingredients:

    How herbs work is determined by the content of the active ingredients. To make sure that every production has the same effect, Cavalor relies on extracts. In contrast to dried herbs, extracts always have the same active ingredient content.

    Vitex agnus castus: has a regulatory effect on various hormonal systems. This berry has a harmonising effect on the mare’s hormonal balance, which produces a normal, regular and balanced cycle. This plant also has a positive effect on (female) fertility and inhibits the sex drive of stallions with an excess of testosterone. The plant owes its ‘monk’s pepper’ nickname to its use during the Middle Ages to suppress the irresistible desires of the monks.

    Origanum majorana: suppresses the production of testosterone and mood swings during oestrus, promotes the mare’s rideability.

    Taraxacum officinale: helps the liver eliminate waste produced during the fertility cycle.

    Humulus lupulus: has a relaxing effect on the central nervous system.

    Achillea millefolium: relieves cramps associated with the menstrual cycle.

    Magnesium bisglycinate: organic, highly absorbable form of magnesium. Has a soothing effect and helps muscles relax.

    Vitamin B6: has a positive effect on the metabolism and promotes the absorption of active ingredients.

    Vitex agnus castus 10,000mg/l, Oreganum majorana 10,000mg/l, Taraxacum officinalis 10,000mg/l, Humulus lupulus 10,000mg/l, vitamin b6 48.7mg/l, Magnesiumbisglycinat 16,000mg/l


  • Shake bottle well before each use to ensure consistency of dose administered. (It is normal for some ingredients to settle and form a layer at the bottom with liquid supplements).

    Ponies: Mix 2 x 5ml per day into feed

    Horses: Mix 2 x 10ml per day into feed

    Cavalor Venus can be administered directly into the mouth.

    Maximum of 100ml per horse per day.

    TIP: For some horses a starting dose of 40ml during the first 4 to 5 days is recommended, after which the dose can be gradually reduced.

    * On average, it takes about 3 weeks before an effect is clearly visible. Occasionally, the mare’s behaviour will worsen after a few days. This is a good sign and indicates that the product is working.

    To ensure the most stable cycle possible, administering Cavalor Venus over a prolonged period on a daily basis is recommended. You can also incorporate a break from Cavalor Venus during rest periods or isn’t required to perform.

    TIP: Experience has also proven that Cavalor Venus can be used on stallions and geldings as well. 

    * Store in a cool, dry place. May be stored up to 1.5 years after the production date.
