Ultra Cruz Equine Trace Minerals contains key ingredients that help support overall horse health. Minerals are essential for muscle contraction, nerve impulse conduction and fluid balance (1, 2). Mineral deficiency can be caused by supplying minerals at lower than recommended amounts. The rapid consumption of minerals in the body depends on conditions such as growth rate. In young horses, mineral deficiency during development can cause skeletal abnormalities. Minerals are also secreted during perspiration, such as in performance horses, and must be replaced.
