Minerals are essential substances that are found in nature. Humans can't make minerals, and lack of minerals can lead to symptoms of diseases. The most common minerals are calcium, potassium, magnesium, sodium, sulphur, chlorine, and phosphorus. Trace elements are minerals that are needed in small amounts (less than 100 mg per day). The most important trace elements are zinc, iron, selenium, iodine, copper, cobalt, and molybdenum. Minerals need to continuously be supplied through diet or dietary supplements for you to feel healthy. The best minerals we've found are from Innate Response and MegaFood.
