Coral is a sea animal similar to sea anemone. Unlike sea anemone, coral produce a skeletal structure that contains calcium. Some coral live in colonies that form coral reefs. Don't confuse coral with coral root (Corallorhiza odontorhiza).

Coral is most commonly used by surgeons as a surgical replacement for bone. It is also used as a calcium supplement, for cancer, for heart disease, and for other conditions, but there is no good scientific evidence to support these other uses.
When taken by mouth: There isn't enough reliable information to know if coral is safe. Some coral products contain lead.

When used as a bone substitute: Coral is LIKELY SAFE for most people when used in surgery as a bone substitute. Some people might get an infection, but this is a possibility in any surgery.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if coral is safe to use when pregnant or breast feeding. Stay on the safe side and avoid use.


NatMed Pro rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.
Likely effective Effectiveness definitions
  • Use as a surgical replacement for bone. Coral can be used in place of bone for spinal fusions and bone tumors. It can also be used in dental, facial, and other surgeries. Coral offers some advantages over bone transplants. It has a lower rate of infection and doesn't carry the risk of transmitting HIV, hepatitis, or Creutzfeldt-Jakob disease.
Possibly effective Effectiveness definitions
Likely ineffective Effectiveness definitions
Possibly ineffective Effectiveness definitions
Insufficient evidence Effectiveness definitions
  • Calcium supplementation.
  • Multiple sclerosis (MS).
  • Cancer.
  • Heart disease.
  • Other conditions.
More evidence is needed to rate the effectiveness of coral for these uses.
