Hormonal supplements for mares: what’s on the market?

  • Horse & Hound is supported by its audience. When you purchase through links on our site, we may earn commission on some of the items you choose to buy.
  • Everyone knows a “moody mare” – whether their hormones are causing them to be difficult to handle, ride or train, or are interfering with a broodmare’s natural breeding cycle, it can present a real challenge. But this is something that supplements for moody mares can help with. The length of a mare’s natural breeding season varies, but it typically starts around March/April each year, so spring is a great time to begin supplementing to encourage regularity, reduce unpredictability and support more consistent behaviour, which will in turn lead to improved performance.

    Most hormonal supplements for mares are a combination of a range of herbs that are known for their regulating and calming properties.

    If you compete with your horse then it is important you make sure any supplements you use do not contain any prohibited substances.
