Coral Calcium (Sango Coral)

Coral Calcium derived from Sango coral (Okinawa, Japan) is primarily a mineral supplement, not a macronutrient source. Key composition per typical serving (~1,000–1,500 mg of coral powder): Primary Minerals: Calcium (~24% by weight, yielding ~240 mg elemental calcium per 1,000 mg coral powder) predominantly as calcium carbonate with minor calcium orotate and calcium ascorbate forms; Magnesium (~12% by weight, ~120 mg per 1,000 mg) in a natural 2:1 Ca:Mg ratio, present as magnesium carbonate and magnesium oxide. Trace Minerals (73+ identified): Strontium (~0.3–0.5%), Iron (~0.02%), Zinc (~0.01–0.03%), Selenium (~0.001%), Manganese (~0.005%), Chromium (~trace), Vanadium (~trace), Copper (~0.002%), Boron (~0.003%), Molybdenum (~trace), Silicon (~0.1%), and Cesium (~trace). Bioavailability Notes: Coral calcium exhibits notably higher bioavailability compared to standard calcium carbonate supplements — studies suggest absorption rates of approximately 40–70% versus 20–30% for conventional calcium carbonate, attributed to its naturally porous, fossilized marine structure and ionic mineral form. The naturally occurring 2:1 calcium-to-magnesium ratio closely mirrors optimal physiological ratios, enhancing synergistic absorption. The alkaline pH (~10–12 when dissolved) may aid calcium ionization in the stomach, particularly beneficial for individuals with reduced gastric acid (e.g., elderly populations). Trace minerals such as strontium and boron further support calcium uptake and bone matrix incorporation. Contains no significant macronutrients (protein, fat, carbohydrate, fiber are essentially 0 g). No vitamins are naturally present unless fortified (some commercial products add Vitamin D3 at 200–1,000 IU per serving to further enhance calcium absorption). Caloric content is negligible (0 kcal). The mineral profile is naturally derived from fossilized coral reefs (above-sea harvesting), not synthetic, which contributes to the organic matrix and superior ionic trace mineral delivery.
