Study of the Impact of Mother-of-pearl Nutritional Supplementation on the Prevention of Post-menopausal Osteoporosis

"The mother-of-pearl, derived from the inner shell of marine molluscs, is composed of calcium carbonate and organic compounds, some of which peptides are active on the bone.~The mineralization inducing activity of the molecules extracted from the mother-of-pearl has been shown in vitro. Mother-of-pearl extract also contains molecules that inhibit the resorption activity of osteoclasts. Mother-of-pearl compounds can thus slow bone remodelling as showed in an ovariectomy-induced osteoporosis model in rat, where mother-of-pearl supplementation showed a better effect on limitation of bone loss than calcium carbonate supplementation."

Calcium carbonate is a source of calcium.
