Vitamin and mineral supplements
The most common type of supplements are vitamin and mineral supplements. These products often contain vitamins A, D, E plus several B vitamins and vitamin C. In addition, they contain a wide spectrum of macro and micro minerals. The purpose of these products is to ensure that the ration contains enough of these vitamin and mineral nutrients.
Where the horse's ration consists mainly of roughage or roughage and grains (oats or barley) a vitamin/mineral supplement will generally need to be included. Most supplements have a balanced nutrient content that is effective as long as manufacturer's recommendations for use are followed.
