Formulation Notes

Nature's Sea Calcium is derived from Lithothamnium, a hard, brittle red algae that grows off the southwestern coast of Ireland. As it grows, the algae incorporates naturally-occurring calcium into its organic structure. Lithothamnium provides a renewable source as the living algae is left undisturbed.
