Discover Mareish supplement for hormonal mares. Formulated to ensure you get the best from your mare at all times, not just when they aren’t in season!
I swapped to Mareish from another product just as my mare was coming into season (and on box rest!). It's only been a few days and already I can see the difference.
Marish is specially formulated to address various factors that contribute to a mare displaying 'mareish' behaviour. Regulating their hormones supports a healthy liver, which in turn improves hormonal balance, regulates the reproductive system and improves fertility, helps with mood and irritability, and helps to eliminate muscle tension that may occur during oestrus.
See the Key Benefits tab below for a detailed breakdown of how each of these ingredients can benefit your mare.

Milk Thistle
The antioxidants and anti-inflammatory properties of milk thistle help to support a healthy liver, which in turn improves hormonal balance.High in Linoleic Acid, Milk thistle can be particularly helpful for mares with hormonal imbalances such as estrus-related behavioural problems, irregular cycles, or ovarian cysts.
Agnus Castus (Chaste Tree Berry)
Agnus castus, also known as chaste tree berry, is a herbal supplement that has been used for centuries to support hormonal balance in both humans and animals. In horses, agnus castus is used as a natural way to regulate the reproductive system and improve fertility.Agnus castus stimulates the pituitary gland to produce more luteinizing hormone (LH) and less follicle-stimulating hormone (FSH). This can lead to an increase in progesterone production and a decrease in oestrogen production, which may help to balance the hormonal system.
Agnus castus helps to manage behavioural issues related to the oestrous cycle, such as aggression, nervousness, or discomfort.
Lemon Balm Extract
Lemon balm, also known by its scientific name Melissa officinalis, is a herb that has been traditionally used for its calming and soothing properties. Known for its soothing effect on the nervous system, gastrointestinal tract and helps with irritability.Lemon balm works by interacting with certain neurotransmitters in the brain, including GABA and acetylcholine. These neurotransmitters play a role in regulating mood, sleep, and other aspects of the nervous system.
Vitamin B6
Vitamin B6, also known as pyridoxine, is an essential nutrient that plays a role in many bodily functions, including the production and regulation of hormones.Vitamin B6 helps to regulate the production of several hormones, including oestrogen, progesterone, and testosterone. It also plays a role in the regulation of mood and behaviour, as it is involved in the synthesis of neurotransmitters such as serotonin and dopamine. Vitamin B6 helps to support mares with hormonal imbalances, such as irregular cycles, behavioural issues related to estrus, or ovarian cysts.
L-Arginine
L-Arginine is an amino acid that is involved in many physiological processes in the body, including the production of hormones.L-Arginine plays a role in the production of several hormones, including growth hormone, insulin, and oestrogen. It helps to improve blood flow to the reproductive organs, which can support healthy reproductive function.
L-Arginine supports mares with hormonal imbalances, such as irregular cycles, behavioural issues related to estrus, or fertility issues.
L-Tyrosine
L-Tyrosine is an amino acid that is involved in the production of several important neurotransmitters in the brain, including dopamine, norepinephrine, and epinephrine. L-tyrosine helps to support cognitive function, enhance mood, and reduce stress.Magnesium
In the nervous system, magnesium is involved in the release of serotonin, the ‘happy hormone’, and helps to control the stress hormone cortisol. Magnesium also helps to relieve muscle tension that may occur during oestrus.Our products are free of fillers, bulkers and unnecessary ingredients. We use only the purest ingredients available to ensure your horse is receiving the best nutrition possible. Our products are also backed by our 100% satisfaction guarantee.
