We personally use all the products we carry for our own horses.  We strive to give our horses feed and supplements of the highest quality, organic and non genetically modified whenever possible.  The consequences of feeding GM (genetically modified) ingredients for our animals as well as ourselves are unknown.  Until it can be proven that such ingredients are safe, we opt to avoid them.  Formula⁴Feet and Speedi-Beet are made in the UK and are certified Non-GM. European supplements are governed by even more stringent regulations than the US with product ingredients traceable from "field to feed".
A.B.C. products are made here in the US with organic ingredients.  Their free-choice vitamin, mineral and trace mineral system lets the individual horse decide what it needs to fill the gap with the changing seasons and variations of feed and water quality. 

We encourage you to feed your horses the best quality hay (low sugar/carb/starch) and a more natural diet including organic supplements, unprocessed free-choice minerals and salt, organic probiotics, using limited vaccines, and limited or no chemical wormers.  Pesticides, chemical processing and genetically modified feedstuffs can compromise even the healthiest horse.
