Micronutrients & recovery
Micronutrient supplementation alleviates fatigue and improves physical performance in individuals with marginal deficiencies, but does not enhance performance in those with adequate dietary intake.
If you are chronically tired and eat a restricted or poor-quality diet, a multivitamin may help restore your energy levels, but it will not work instantly. You must take it consistently for at least 6 weeks to see benefits. If you already eat a balanced, nutrient-rich diet, adding supplements is unlikely to improve your energy or performance.
Micronutrient supplementation can alleviate deficiencies, but supplements must be taken for an adequate period of time.
