Deficiencies can impair performance, leading to fatigue and increased susceptibility to illness. Key micronutrients like iron and calcium play critical roles in endurance and strength, respectively. A well-rounded diet containing a spectrum of vitamins and minerals is essential for optimal physical performance.
