| We believe this product surpasses any other coral calcium product on the market. All the calcium is 100 % marine grade ionized calcium, no calcium carbonate or calcium citrate or other fillers found in many of the other products. There are two classes of marine grade coral calcium. One of them, called sango mineral powder (SMP), is of far better quality because it contains the largest number of naturally occurring minerals from the sea and calcium to magnesium in the perfect biological ratio (2:1). Nature's Renewal Sango Supreme Coral Calcium is made from 100% marine grade SMP from Okinawa, Japan. |
