Nearly 70% of minerals found in a horses? body are made up of Calcium, Magnesium and Phosphorous. These minerals are critical for bone, teeth, joint and cartilage health. For the active working horse, between 25% and 50% of absorbed calcium is lost during exercise or competition. Unfortunately, many soils across Australia are Calcium deficient making mineral rich pasture difficult to cultivate. If your horse is restricted to a small paddock, locked in a stable, or kept in a paddock with poor pasture, how are you maintaining your horses? mineral requirements? The NRG Team has spent considerable time developing a quality and cost-effective mineral supplement that ensures your horse achieves the daily mineral requirement and helps avoid costly leg and skeletal problems. NRG?s Calcium has added Magnesium and Selenium for high absorption and the correct balance of Phosphorous to combat feed imbalance. Excess Phosphorus in the horses? diet leads to less calcium being absorbed.
