While macronutrients (carbohydrates, proteins, and fats) are vital, micronutrients (vitamins and minerals) are equally crucial for fitness. They are crucial to producing energy, immune function, and various physiological processes integral to exercise performance. Nutrients such as vitamin D, calcium, iron, and magnesium are especially noteworthy for their impact on muscle function, bone health, and oxygen transport. Incorporating nutrient-dense foods into your meals ensures your body has the tools to excel during workouts.
