Mag-E is a magnesium-based supplement commonly used to support muscle function, nerve health, and overall well-being in horses. Magnesium plays a crucial role in reducing muscle tension, promoting relaxation, and managing stress-related behaviors. Mag-E is often given to horses that experience anxiety, nervousness, or muscle stiffness, especially during training or competition. Adequate magnesium levels can also contribute to improved focus and performance. Regular supplementation may help maintain proper muscle function and prevent deficiencies that could impact a horse’s overall health. Consulting a veterinarian is recommended to determine the appropriate dosage and ensure balanced nutrition for equine care.
