Aquamin is a blend of mineral derived from red algae harvested off the coasts of Ireland and Iceland. Aquamin is an abundant vegetarian source of bioavailable Calcium and Magnesium and has over 70 other important trace minerals. Research indicates that this multi-mineral complex may support proper bone mineralization and helps to regulate key factors involved in the normal immune system response to typical joint usage. Clinical studies demonstrate that Aquamin can help to support joint comfort and mobility. A vegetarian-sourced Vitamin D is added to this formula to further support bone health.
