Health and Environmental Concerns
Living coral reefs are endangered and cannot be harvested without significant damage to the ecosystem, and because of this, coral calcium is harvested by grinding up above-ground limestone deposits that were once part of a coral reef. Calcium from coral sources needs to be refined to remove pollutants of the source environment. It is marketed as a dietary supplement, but its benefits over other calcium supplements are unproven and biologically unlikely, and several marketers have been found guilty of fraud and were ordered to pay $20.4 million and to refrain from making unsubstantiated claims in the future. Additionally, coral near Okinawa has absorbed relatively high amounts of lead and mercury, leading to concern that these unregulated supplements may be contaminated. Further, coral takes millennia to grow, leading to environmental concerns.

“Plants are the young of the world, vessels of health and vigor; but they grope ever upwards towards consciousness; the trees are imperfect men, and seem to bemoan their imprisonment, rooted in the ground.”
—Ralph Waldo Emerson (1803–1882)
“At last I feel the equal of my parents. Knowing you are going to have a child is like extending yourself in the world, setting up a tent and saying “Here I am, I am important.” Now that I’m going to have a child it’s like the balance is even. My hand is as rich as theirs, maybe for the first time. I am no longer just a child.”
—Anonymous Father. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 5 (1978)
