Vitamin D is essential for anyone engaging in regular exercise. It supports muscle function by aiding calcium absorption, which strengthens muscles and bones, reducing the risk of injuries during workouts. Adequate Vitamin D levels enhance muscle recovery, helping you bounce back faster after intense sessions. It also boosts energy levels and endurance, allowing for more effective training. Additionally, Vitamin D supports immune health, keeping you consistent with your workout routine. Ensure you get enough through sunlight, foods like fatty fish or fortified dairy, or supplements if needed.
