The Horse First calmer range is a popular choice. The RelaxMe collection offers a unique double action formula which works on both the gut and the nervous system. Horse First were established in 2008 by horse producer Paddy Hughes in conjunction with an equine-related nutritionist and chemist. Their products offer the highest levels of active-ingredient inclusion of any supplement on the market. At Houghton Country we offer a large selection of horse calmers, all of which are available with next day delivery if you need them quickly!
