Micronutrients, including vitamins and minerals, play a critical role in energy production by facilitating various biochemical reactions in the body. For example, B vitamins are essential for converting food into energy, while iron is necessary for oxygen transport. Without adequate micronutrients, the body may struggle to produce energy efficiently, which can lead to fatigue and decreased performance during physical activities. Ensuring sufficient intake of these nutrients is vital for optimal metabolic function and overall health.
