Want to have an expert build a nutrition program specifically for your horse? This service is an excellent choice for all performance horses as well as those horses with complex health concerns such as insulin resistance, equine metabolic syndrome, PSSM, and equine asthma. A personalized nutrition program will then be created that takes into consideration the type of forage being fed and makes recommendations for specific products both feeds and supplements as needed.


Highlevel performance horses often travel great distances to compete, sometimes to locations where their regular feeds are not available. It is not always possible to ship feed due to cost and/or customs restrictions. This poses a unique problem since many horses competing internationally have well dialed-in diets that are working well. EnviroEquine’s consulting nutritionist Dr. Clair Thunes can help you select feeds that will most closely match what you are successfully feeding at home.
