What the studies say
This study explores zinc requirements, as well as the benefits and risks of supplementation. It highlights that a large proportion of the world’s population is at risk of zinc deficiency, but also warns of the toxicity associated with excessive intake of supplements. The study highlights the complexity of assessing zinc status and suggests that zinc may be effective in preventing certain conditions, such as those associated with diabetes.
