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.
