How are we different?

Our top-quality Sango coral products are sourced directly from the leading producer in Okinawa, the southernmost islands of Japan. They are gently and sustainably collected at a depth of over 50m. Due to the lack of light at this depth, corals cannot survive and are naturally deposited at the bottom of the sea around the massive Okinawa reef every year. These are therefore guaranteed fossil stocks — living corals are not affected.

After collection, the fossilised corals are washed, sterilised for at least 10min at 200°C, and dried. The clean corals are sieved to filter out unwanted materials, then ground into a powder. The fine porous structure of the fossil coral, which is preserved throughout the careful production process, ensures that the powder has a high surface area and ionises quickly and easily, resulting in a highly bioavailable product. The coral powder is tested by an independent laboratory in Germany and is guaranteed free from radioactivity (zero Becquerel).

Calcium is the most abundant mineral in the human body. It is stored in about 99% of bones and teeth, contributing to their stability and strength.


Magnesium is an essential mineral and must be consumed daily in sufficient amounts to prevent deficiency. It is involved in numerous important processes in the body.

2:1 Ratio

Calcium and magnesium are particularly well-absorbed by the human body at a ratio of approximately 2:1, which is the ratio found in Sango coral.

High Bioavailability

The organic calcium and magnesium carbonate found in Sango coral is highly bioavailable. This form can be well-absorbed by body cells.

Health Benefits of Calcium and Magnesium According to the European Food Safety Authority (EFSA)

Calcium contributes to:

  • Normal blood clotting
  • Normal cellular energy production
  • Normal muscle function
  • Normal neurotransmission
  • Normal digestive enzyme function
  • Cell division and specialisation
  • The maintenance of bones and teeth
  • Reducing the risk of post-menopausal bone mineral density decline. Low bone mineral density is a risk factor for osteoporotic fractures
  • Normal growth and bone development in children

Magnesium contributes to:

  • The reduction of tiredness and fatigue
  • Electrolyte balance
  • Normal energy metabolism
  • Normal functioning of the nervous system
  • Normal muscle function
  • Normal protein synthesis
  • Normal psychological function
  • The maintenance of normal bones
  • The maintenance of normal teeth

Magnesium has a function in cell division.


Recommended Dosage
