Abstract

Micronutrients are essential elements for a good health state. However, the use of micronutrient supplements is a double-edged sword. For instance, the toxicity of micronutrients may be fatal in many cases. Meanwhile, micronutrient supplements are commonly used among children and pregnant women. Therefore, knowledge about the safety burden of micronutrient use is necessary for preventing severe events for both subgroups. However, the available data regarding micronutrient toxicity are limited. In this review, we discussed the toxicity and the adverse events of common micronutrients due to excessive intake and misuse of micronutrient supplements.

Key words: Micronutrients, toxicity, Vitamin D, Vitamin A, Iron.
