  • Note: This review does not include a detailed description of calcium.

Background
  • Corals are sea animals that grow in colonies. Corals are most often found in tropical oceans and are known as reef builders because they secrete calcium carbonate to form a hard skeleton.
  • Natural and man-made coral are currently being studied for use in bone grafts. Coral has been shown to increase bone strength when incorporated into surrounding bone.
  • Although coral may be useful as a bone graft substitute, researchers state that more long-term information on safety and effectiveness is needed. Coral has been associated with an increased rate of infection and may cause problems in those who have or are prone to kidney stones.

Evidence Table

These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. GRADE *

F: Strong scientific evidence against this use (it likley does not work)


Tradition / Theory

The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.

  • Arthritis, cancer, heart disease.

Dosing

Adults (18 years and older)

  • There is no proven safe or effective dose for coral.

Children (under 18 years old)

  • There is no proven safe or effective dose for coral. Use in children is not recommended.

Safety

The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.

Allergies

  • Avoid with allergy or hypersensitivity to coral.

Side Effects and Warnings

  • Coral should be avoided in people who have or are prone to kidney disease or kidney stones. Coral may increase the risk of infection and wound irritation when used for bone grafting.

Pregnancy and Breastfeeding

  • Coral is not recommended in pregnant or breastfeeding women due to a lack of available scientific evidence.

Interactions

Interactions with Drugs

  • Coral, which contains calcium, may theoretically interact with blood pressure medications called calcium channel blockers (such as verapamil or diltiazem).

Interactions with Herbs and Dietary Supplements

  • Coral contains calcium and may have additive effects when take with other supplements containing calcium, especially in people who have kidney problems or kidney stones.
