The human brain’s extraordinary metabolic demands—consuming approximately 20% of total body energy in adults and up to 50% in children around age 10—depend critically on adequate micronutrient availability. Recent biochemical research demonstrates that B vitamins including B6, B12, folate, thiamine, and niacin serve as essential cofactors in metabolic pathways that power neural signaling and sustain neuronal health. These micronutrients regulate homocysteine levels, support ATP production for energy metabolism, facilitate neurotransmitter synthesis, and maintain myelin integrity—all fundamental to cognitive function. Deficiencies in key B vitamins are associated with cognitive decline, neuropathy, and reversible neurological symptoms. By ensuring adequate micronutrient status throughout the lifespan, individuals can support long-term cognitive resilience and potentially slow age-related brain atrophy. Understanding the brain’s nutritional requirements emphasizes the importance of micronutrient-rich dietary patterns for optimal neurological health. Read the full article on GMJ Newsroom.
