[Immunonutrition and (its impact on) health. Micronutrients and debilitating factors].

Introduction: the interaction between immunity and nutrition is complex and multifaceted. Micronutrients, including vitamins and minerals, are essential for immune function. In turn, immune function and lifestyle habits can affect nutritional needs and micronutrient utilization, creating an interdependence between nutrition and immunity that can be modulated by both external and internal factors.

[Review and update of the importance of micronutrients in pediatric age: a holistic view].

International health institutions have implemented protocols and nutritional health policies in the promotion of health and brain development. However, these policies do not usually extend to preschool age, being a stage of important changes and very dynamic development. Therefore the objective of this work is to carry out a review of the information available about nutritional needs throughout the process of human development, emphasizing the main micronutrients, their role in development and what the evidence tells us about the effects of it lack.

Potential mental and physical benefits of supplementation with a high-dose, B-complex multivitamin/mineral supplement: What is the evidence?

Objective: to perform a systematic literature review to examine the effects of high-dose, B-complex multivitamin/mineral supplementation on physical, mental, and energy outcomes in healthy and 'at-risk' (suboptimal nutritional status/subclinical symptoms at baseline) adult populations. Methods: PubMed was searched for relevant randomized controlled trials until January 2020. Results: overall, 136 publications were identified.

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

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.
