Application areas

Magnesium in Animal Nutrition

Benefit: Support for Muscle and Nerve Function

In the animal’s body, approximately 50 percent of magnesium is stored in the skeleton. Here, it plays a key role in the development and stability of bones, alongside calcium and phosphorus. Another 45 percent is found within the body’s cells, where magnesium acts as an essential activator of many enzymes. It is particularly important for metabolism and muscle performance. Only about five percent of the body’s magnesium is located in the extracellular space, where it plays a crucial role in the excitability of muscles and nerves.

Magnesium in Animal Nutrition

Benefit: Relaxation and Stress Regulation

Proper muscle function requires a balance between calcium and magnesium: while calcium triggers muscle contraction, magnesium ensures relaxation. A magnesium deficiency disrupts this interplay—leading to muscle tension, tremors, cramps, and in severe cases, tetany or heart problems. The nervous system is also affected: symptoms may include nervousness, restlessness, reduced feed intake, and panic reactions.

Magnesium in Animal Nutrition

Benefit: Support During Growth and Performance

During periods of increased demand—such as growth, pregnancy, lactation, aging, or intense physical stress—the natural magnesium supply is often insufficient. Additionally, stress, sweating, or diarrhea can lead to significant losses. Targeted magnesium supplementation can help improve well-being, increase stress tolerance, and have a positive impact on meat quality.
