From Mitochondrial Support to Mitohormetic Readiness: A Micronutrient-Centric Extension of the Energy Allocation System

This review proposes that selected micronutrients may contribute to mitohormetic readiness, defined here as the pre-existing biochemical and regulatory capacity of a cell, tissue, or organism to sense, buffer, and transduce a bounded mitochondrial stressor, mount a proportionate adaptive response, and recover toward baseline, or a more capable post-challenge state, without persistent functional loss. This nutrient-centered construct extends the Energy Allocation System (EAS), in which resilience is shaped by how organisms allocate finite metabolic resources under stress and conservation-dominant phenotypes reflect coordinated energy-conserving responses rather than isolated dysfunction. The proposed relevance of micronutrients lies less in direct mitochondrial stimulation than in preserving the endocrine, redox, enzymatic, and one-carbon conditions required for beneficial adaptation. Thyroid physiology is used as the principal nutrient-centered exemplar, particularly through the roles of iodine, selenium, and iron, before the analysis is extended to methylfolate, cobalamin, riboflavin, magnesium, and niacin. The review does not present mitohormetic readiness as an established physiological principle or validated clinical construct, but as a hypothesis-generating extension of the EAS intended to refine how resilience, metabolic flexibility, and biochemical sufficiency are interpreted in clinical bioenergetics.
