Benefits of micronutrient supplementation on nutritional status, energy metabolism, and subjective wellbeing

Silvia Maggini, Veronika Óvári, Inmaculada Ferreres Giménez, María Gloria Pueyo Alamán

The human body, particularly the brain, requires energy, stored in the form of adenosine triphosphate. Energy metabolism during cellular respiration is dependent on the presence of multiple micronutrients, which act as essential components, coenzymes, or precursors at every stage. An adequate supply of multiple micronutrients is vital for efficient energy production. However, micronutrient intakes below the recommended dietary allowance are common, even in industrialized countries. Intakes of vitamins A, D, E, folate, iron, zinc, and selenium are suboptimal across all age groups. Suboptimal micronutrient levels have been shown to contribute to low energy levels, physical and mental fatigue, and impaired cognitive performance and wellbeing – symptoms frequently present in the general population. When supplemented in combination in well-conducted trials, multiple micronutrients ± coenzyme Q10 reduced oxidative stress in chronic fatigue syndrome; in healthy people they increased cerebral blood-flow hemodynamic response, energy expenditure, and fat oxidation; reduced mental and physical fatigue; improved the speed and accuracy of cognitive function during demanding tasks; and reduced stress. The results from these clinical trials suggest that even in industrialized countries, where adults might be assumed to have a healthy, balanced diet, there is a rationale to supplement with multiple micronutrients, including coenzyme Q10, to improve nutritional status, support energy metabolism, and improve subjective wellbeing.
