Horses require a broad spectrum of essential vitamins and trace elements for health, vitality and performance. The natural forage diet can supply many of these nutrients, however that supply is not consistent. Soil deficiencies, weather, time of year and method of preservation will all impact on the nutrient spectrum of grazing and forage. It is common practice these days to add a compound feed to the diet that has an added vitamin and mineral content, or to provide a supplementary source of vitamin and minerals. Using a supplement ensures that your horse will be receiving sufficient levels for his required performance, and it allows the ability to feed a reduced level of concentrate if your horse is fed a preferred high fibre diet, or is affected by weight gain, excitability, gastric or metabolic conditions.

Additionally hard work can impact on the whole system, including the immune system, as the horse's system works to meet the challenges of the modern equine lifestyle. Look for signs of system challenge, such as poor performance and days lost from training, which may indicate that your horse requires a little extra help.
