How are we different?

Our high-quality Sango coral products are sourced directly from the market leader in Okinawa, the southernmost region of Japan. They are 100% pure and are sustainably sourced at depths of over 50m. Due to the lack of sunlight, corals cannot live at such depths, and this product is derived from the fossilised remains of dead corals that have been naturally deposited at the bottom of the sea. This leaves the living corals around the Okinawa reef healthy and unaffected.

After harvesting, the fossil corals are washed, sterilised for over 10 minutes at 200°C, and then dried. The corals are then sieved to filter out unwanted materials, then pulverised. The fine porous structure of the fossil coral, which is preserved by this production process, ensures that the powder has a large surface-area and that it can be ionised, thus resulting in a highly bioavailable product. The coral powder is tested by an independent laboratory in Germany, and is guaranteed free from radioactivity (contains zero becquerels).

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 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

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

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.
