Copper's current roles and metabolic control are evolutionarily conserved. Copper mediates the use of oxygen in energy generation, this depends on copper's ability to switch between Cu+ (cuprous) and Cu2+ (cupric) forms in capturing and releasing protons, as in cytochrome c oxidase in the respiratory chain. Its other roles support connective tissue...
Abstract Vitamins and essential minerals are micronutrients that are essential for the normal functioning of the human body. However, they may lead to adverse health effects if consumed in excess. The concept of a tolerable upper intake level (UL) is a science‐based reference value, which was introduced to support policy‐makers and other relevant a...
Vitamin A deficiency is a major health risk for infants and children in low- and middle- income countries. This scoping review identified, quantified, and mapped research for use in updating nutrient requirements and upper limits for vitamin A in children aged 0 to 48 months, using health- based or modelling-based approaches. Structured searches we...
Recommendations aimed at protecting the public from toxicity of essential elements including essential metals have usually been developed separately from those recommendations aimed at protection from deficiency.
