Calcium from coral is primarily calcium carbonate, which is used as a dietary calcium supplement. Coral calcium is mined from the coral beds along the coastline and is then typically ground into a fine powder and heated. Preliminary scientific investigations indicate that coral calcium may provide health benefits. However, the advice of a medical professional should be sought before trying to prevent, treat or cure any condition with coral calcium.
Coral calcium was found to be an antioxidant, in a study published in 2009 in "Biomaterials." Antioxidants are an important component of health. This is because they work on a cellular level thereby reducing the onset of disease in general. When cells use oxygen to produce energy, they give off harmful byproducts called free radicals that can attack healthy cells. However, antioxidants attach themselves to free radicals and prevent them from damaging or killing cells.
Accelerated senescence is essentially rapid aging. Coral calcium may help prevent this from occurring. The 2009 study in "Biomaterials" found that coral calcium protected against accelerated senescence in the brains of mice. The coral calcium supplementation worked by affecting the processes of genes involved with cellular preservation.
Coral calcium may help promote bone growth. A study published in 2010 in the "Journal of Oral Implantology" revealed that bone tissue was grown in the presence of coral calcium. The researchers implanted graphs that contained coral calcium with steel rods into the bones of mice that lead to accelerated bone growth compared to controls. The researchers noted that coral calcium improved bone growth by roughly 36 percent.
Coral calcium has been associated with longer lifespans among certain ethnic groups. For example, people in Okinawa,, Japan as well as people of the mountainous regions of Pakistan commonly enjoy long lives. Scientific observation has revealed that one of the contributing factors is the intake of minerals. In these regions, coral calcium is one such mineral source, according to an article published in July 2008 in the "Townsend Letter."
