Micronutrients, including vitamins and minerals, play a vital role in a fitness-oriented diet. They support metabolic processes, enhance immune function, and improve energy production. Key micronutrients like vitamin D, iron, and zinc are important for muscle recovery and optimal performance. Deficiencies in micronutrients can impair muscle growth, exercise recovery, and overall health. Therefore, a balanced intake from fruits, vegetables, and whole foods ensures adequate levels, contributing significantly to fitness goals and health maintenance.
