Coral Calcium Complex is a formula designed to support the absorption of Calcium and Minerals. The manufacturer is the US-based company Only Natural, established in 1986. The main ingredient is 100% uncut Sango Coral Calcium–a coral mineral powder that is of the finest quality.

The supplement comes in vegetable capsules as a natural combination of Sango coral calcium, vitamins, and minerals. Its effectiveness in increasing calcium absorption is supposedly determined by the trace minerals deposited during the coral’s formation process.

This product is manufactured by Only Natural, a company with an experience of over 25 years, specialized in commercializing herbal supplements and vitamins, unique among similar products.

Coral Calcium Complex is offered as a natural alternative for 2 of the most essential body systems (bone and muscle) and for achieving and maintaining a good healthy body.


1) Coral Calcium Complex at a Glance

Coral Calcium Complex is a vitamin-, mineral-, and calcium-based formula. Its main active ingredient is uncut Sango Coral Calcium, harvested under strict regulations and supervised by the Japanese government, which guarantees the coral reef’s protection.

According to the manufacturer, the coral calcium is originated in the Sango Reefs in Okinawa, Japan. It is believed to be the only coral with a filtering effect, unique among the 25,000 species known today.

Coral Calcium and minerals are considered essential compounds for energy production, a healthy heart function, and the immune system. It is also believed they may help the body prevent diseases caused by bone loss such as osteoporosis.

The supplement is not recommended for pregnant or lactating women, hypoglycemic, diabetics, and people with known medical conditions and/or already under medication without a licensed physician’s consent.

Coral Calcium Complex contains the following ingredients: Coral Calcium (Sango coral mineral powder), Vitamin, Magnesium, and Boron Chelate.

3) Does Coral Calcium Complex Work?

Coral Calcium Complex is claimed to contain a 100% certified uncut Sango Coral Calcium (coral mineral powder). As one of this product’s ingredients, Calcium is known to be vital for healthy teeth, gums, blood pressure, and the transmission of nerve impulses.

Studies have shown that Calcium is also necessary for muscular growth, contractions, and prevention of muscle cramps and bone loss associated with osteoporosis. However, calcium usage might lead to some side effects such as bloating, gas, and constipation.

Generally speaking, calcium supplements are well tolerated by the body. The 1994 National Institute of Health Consensus Development Conference on Optimal Calcium Intake reviewed the published literature on dietary and supplementary Calcium.

The final report noted that side effects had been reported on high doses of Calcium.

Still, an increase in calcium consumption up to 2 mg per day represents a safe measure. Therefore, Coral Calcium Complex represents a good alternative for people as long as the recommended dosage is not exceeded.
