O2B Calci-Mag contains the human body’s preferred ratio of calcium to magnesium to maximize absorption and utilization of these essential minerals. The human body needs adequate levels of magnesium in order to properly use calcium, therefore a magnesium deficiency can affect calcium metabolism and alter levels of certain hormones that regulate calcium in the body.

The body contains more calcium than any other mineral with over 98% forming bone tissue and the remainder needed for a healthy nervous system, promoting blood clotting factors and muscle contraction. Nearly half the total Magnesium found in the body is found in soft tissue and 30% of that is located in smooth muscle, with the remaining found in the bone matrix.

As nutrients do not work in isolation in the body, O2B Calci-Mag contains other key nutrients including Vitamin D and Zinc to further enhance the absorption and utilization to support healthy bones and teeth.

Key benefits:

  • Supports the building of healthy bones and teeth

  1. Great for sore muscles and faster recovery

    Review by Bridie

    O2B Healthy’s Calcium and Magnesium tablets have been super helpful to me and my training…I take both tablets 1 hour before bed. I would definitely recommend both to growing teenagers and athletes who are restless when going to bed. These tablets aren’t too big and don’t have a bad after taste.
