Coral calcium comes from aquatic coral structures and reefs. This nutritional supplement may contain varying amounts of both calcium and magnesium, depending on the source. Although some manufacturers of coral calcium claim this supplement provides special health qualities, there is no evidence supporting these claims. The calcium and magnesium in coral calcium supplements may play a role in the development of kidney stones. Only take nutritional supplements under the supervision of a health care professional, especially if you suffer from kidney stones.
Coral Calcium
As with several other types of nutritional supplements, coral calcium supplements are surrounded by hype, according to Dr. Robert Keith, a nutrition professor with the Alabama Cooperative Extension System. Coral calcium supplements contain a form of calcium carbonate, as well as the mineral magnesium. Some proponents of coral calcium supplementation claim it may help lower blood pressure, help you lose weight and cure colon cancer, although current research does not substantiate these claims.
Calcium
The standard dosage for preventing low calcium levels is 1 g of elemental calcium per day. Natural sources of calcium include dairy products, broccoli, kale, canned fish that has bones and calcium-enriched juices, as well as some soy products. A diet too high in calcium may increase the likelihood of developing kidney stones, notes the University of Maryland Medical Center. High doses of calcium supplements may reduce the amount of magnesium your body absorbs.
Magnesium
Your body contains relatively large amounts of magnesium. This mineral helps perform more than 300 chemical reactions necessary for proper health. Fibrous foods, including legumes, vegetables and whole grains, as well as dairy products, meats and nuts, are sources of magnesium. MedlinePlus advises that magnesium may be effective in preventing the recurrence of kidney stones.
Kidney Stones
As many as 10 percent of Americans have kidney stones, according to the University of Maryland Medical Center. Kidney stones form for a number of reasons, including excess calcium absorption through the small bowel. Kidney stones can cause excruciating abdominal and back pain, nausea, vomiting, fever and chills. Eating foods rich in magnesium and low in calcium may help reduce the symptoms of kidney stones.
Precautions
Notify your doctor if you experience any symptoms of kidney stones. Discuss the risks and benefits of using coral calcium supplements, as well as other sources of calcium and magnesium, with your doctor. Although coral calcium contains both magnesium and calcium, this type of marine supplement may also contain certain toxins and contaminants, such as mercury and lead. The magnesium in coral calcium may cause diarrhea, vomiting and nausea, while the calcium can lead to belching and gas.
