Calcium Sources: Coral vs. Oyster Shell - Which is Best?

Calcium is an important nutrient for overall health. This mineral is commonly known for its ability to build bones and help in the prevention of osteoporosis.

Diet

• Calcium is present in many types of food and may be obtained by diet. Many individuals, however, require supplemental calcium to obtain the recommended amount.

Supplements

• Supplemental calcium is available in different forms. The most common are calcium citrate and calcium carbonate.

Quality

• Oyster shells and coral reefs both contain calcium carbonate. The calcium carbonate quality does not differ significantly between these two sources.

Lead

• Some oyster shell calcium supplements have been found to contain lead. Lead also has been discovered in some sources of coral calcium.

Differences

• The most obvious difference between these two sources of calcium carbonate is in the price. Coral calcium is normally the most expensive type of this source of calcium.

Production

• The reputation of the supplier is an important consideration when deciding on a calcium supplement. Quality control during production is essential in determining the health value of calcium supplements, including oyster shell and coral calcium.
