This document discusses coral calcium as a source of calcium and other minerals. It notes that coral calcium contains about 30-40% calcium carbonate as well as up to 70 trace elements. Coral calcium has a calcium to magnesium ratio of about 2:1. Studies show coral calcium is well-absorbed and bioavailable, with absorption rates averaging 39%. Coral calcium may help support bone health and density when taken as a dietary supplement.

1. •Coral minerals are different than rock-based calcium carbonate.
• Coral calcium is composed principally of calcium carbonate, which is present in
percentages ranging from 30 % to 40% .
• It is notable that as many as 70 or so different trace elements are present in
coral calcium often in parts per million.
• Coral contains calcium and magnesium in a content ratio of about 2:1 .
•Magnesium is one of the essential minerals for bone formation.
• Recently, stress is laid particularly on the importance of a well-balanced supply
of calcium and magnesium rather than simple calcium intake.

2. • This natural balance is important because mineral works synergistically,
each mineral requiring other minerals to perform its functions.
• Coral minerals are ionic. They take on positive charge upon contact with
moisture, making them easier for human body to assimilate.
• Coral minerals rapidly ionize within 15 minutes, making them easy to
absorb. This is a major difference compared to rock-based calcium
carbonate that requires large amounts of stomach acid for ionization and
absorption
• As the bioavailable calcium and other alkalizing minerals get into the
blood and cells, the body pH returns to the natural slightly alkaline level.

4. Studies
• Absorption of coral-derived calcium is better than that of calcium
carbonate-derived calcium on the average.
• coral calcium given in a balanced composition of 600 mg of calcium
with 300 mg of magnesium and thus providing a 2:1 ratio of the
two elements, produced improvements in bone mineral density.
• Coral is an osteoconductive material used as a bone graft
extender.coral grafts are well tolerated and are simultaneously
partially ossified as the calcified skeleton is resorbed.

5. Conclusion
• Coral calcium is a great and moreover a natural source of calcium.
• Consists of about 40 % elemental calcium.
• It has a perfect blend of calcium and magnesium in a ratio of 2:1.
• Coral calcium contains up to 70 or so different trace elements in small
amounts, so coral calcium is not just calcium; it's a holistic mineral
supplement.
• Shows better absorbtion and bioavailability (39 +/- 3 %)
• Can be used as a dietary supplement such as for the prevention of
osteoporosis.

6. Coral calcium qualifies as an excellent option for supplemental
mineral nutrition. In its powder form it is easy to mix in water or
juice, enabling even small children an easy way to boost their
calcium and magnesium intake.
Coral calcium is a nutrient with great promise.
