Why should I consume the right amount of trace minerals?

Dariush Mozaffarian, MD
Internal Medicine
Too much of one trace mineral can cause or contribute to a deficiency of another; for example, a minor overload of manganese can exacerbate iron deficiency. Having too little can also cause problems. When the body has too little iodine, thyroid hormone production slows, causing sluggishness and weight gain as well as other health concerns. The problem worsens if the body also has too little selenium. The difference between "just enough" and "too much" of the trace minerals is often tiny. Generally, food is a safe source of trace minerals, but if you take supplements, it's important to make sure you're not exceeding safe levels.
