Micronutrient deficiencies in athletes can lead to impaired performance, reduced muscle recovery, and overall health issues. These deficiencies may cause fatigue, decreased endurance, and increased risk of injuries. Essential micronutrients like vitamins and minerals play critical roles in metabolic processes and energy production. Ensuring adequate intake through diet or supplementation is vital for optimizing performance and maintaining health. Addressing these deficiencies can enhance athletic capability, improve recovery times, and promote long-term health in athletes.
