Trace Minerals WHAT ARE TRACE MINERALS? Trace minerals, including iron, copper, zinc, selenium, strontium, molybdenum, manganese, fluoride, iodine, chromium, cobalt, and vanadium, are essential nutrients like macrominerals (sodium, potassium, chloride, calcium, phosphorus, magnesium, and sulphur), which the body cannot produce. Trace minerals must come from food, beverages, and, also, from supplements. Visit - https://www.nationalnutrition.ca/minerals/trace-minerals.html
