Heavy metals often mimic or compete with essential micronutrients for absorption and binding sites, resulting in deficiencies and toxic manifestations. Micronutrient interactions are critical to exploring strategies to overcome heavy metal toxicity due to their significant influence on metal absorption, transportation, metabolism, and detoxification. Essential micronutrients such as zinc, iron, calcium, selenium, and vitamins C and E can modulate the toxicity of heavy metals like lead, cadmium, mercury, and arsenic by competing for absorption sites, enhancing metal excretion, and supporting antioxidant defenses. Deficiency in these micronutrients predisposes individuals to increased susceptibility to metal toxicity, while adequate intake can mitigate harmful effects by reducing metal uptake and alleviating oxidative stress. Additionally, micronutrients facilitate binding to target proteins and metabolic sequestration of toxic metals, thus decreasing cellular damage. The complex interplay between micronutrients and heavy metals suggests that dietary supplementation and nutritional interventions can serve as practical, low-cost approaches for preventing and treating heavy metal toxicity in exposed populations. This rationale underscores the importance of understanding micronutrient-heavy metal interactions to develop effective public health strategies.
