The human body is nothing short of amazing, but it requires mineral supplements in order to properly function. There are two types of minerals: macro minerals and trace minerals. Macro minerals are required in large amounts and include minerals such as magnesium and calcium.

On the other hand, trace minerals are required in much smaller quantities but still have a large impact on your overall health. Common trace minerals include copper, chromium, fluoride, iron, iodine, manganese, magnesium, selenium, molybdenum, and zinc.

At Hargraves Online Healthcare, we sell all of the mineral supplements you need in order to optimize your health. In our online shop, you’ll find a variety of options, including:

  • Zinc supplements
  • Magnesium supplements
  • Iron mineral supplements

We also sell multi-mineral supplements that can be taken with multivitamins to ensure you’re healthy inside and out. Mineral supplements are beneficial in that they can increase energy levels, minimize free radical damage, improve bone health, and support important bodily functions such as cellular growth and repair.

Check out our full line of multi-mineral supplements!
