Beneficial Mineral

What Magnesium Does

Magnesium supports bone health, muscle function, nerve transmission, and energy metabolism. It works closely with calcium and phosphorus — all three minerals need to be in balance for proper bone formation.

How Much?

Typically adequate in a diet containing timothy hay and varied leafy greens.

Signs of Deficiency

Muscle tremors, poor growth, reduced appetite, in severe cases seizures.

Signs of Excess

Excess is normally excreted. Toxicity from food sources is extremely rare.
