73+ Trace Minerals

Coral calcium naturally contains over 73 trace minerals including calcium, magnesium, iron, and zinc — in ratios similar to the human body for optimal absorption.

Bone & Joint Support

The naturally balanced calcium-to-magnesium ratio in coral calcium supports bone density, joint comfort, and overall skeletal health — especially important as we age.

Frequently Asked Questions

What is coral calcium?

Coral calcium is a natural mineral supplement derived from fossilized coral deposits near Okinawa, Japan. Unlike regular calcium supplements made from limestone or chalk, coral calcium contains over 73 trace minerals — including calcium, magnesium, iron, and zinc — in ratios naturally similar to the human body. This unique mineral profile is why Okinawa is considered one of the world's Blue Zones, where residents enjoy some of the longest lifespans on earth.

How is this different from regular calcium supplements?

Most calcium supplements contain only one or two forms of calcium (usually calcium carbonate or calcium citrate) with limited additional minerals. Coral Calcium Marine Plus provides calcium along with 73+ naturally occurring trace minerals in a balanced, bioavailable form. The marine-sourced coral delivers minerals in ratios that closely mirror the human body, supporting superior absorption compared to isolated calcium supplements.

Is the coral sustainably harvested?

Yes. Our coral calcium is harvested exclusively from above-sea fossilized coral deposits near Okinawa, Japan. No living coral reefs are disturbed or damaged in the harvesting process. The fossilized coral is collected from natural land deposits that have been above sea level for thousands of years, making this a fully sustainable and environmentally responsible source.

Who was Bob Barefoot and what is the upgraded formula?

Robert R. Barefoot was a renowned chemist and bestselling author who spent decades researching the health benefits of coral calcium and its role in supporting the body's pH balance. His work brought worldwide attention to Okinawan coral calcium. Our upgraded Barefoot formula builds on his original research with improved sourcing, higher purity standards, and enhanced bioavailability — delivering the same mineral-rich coral calcium in a more potent, modern formulation.

Can I take this with other supplements?

Yes. Coral Calcium Marine Plus is generally safe to take alongside other supplements. Its naturally balanced mineral profile complements most supplement routines. However, if you are taking prescription medications (especially blood thinners or thyroid medications) or other calcium-containing supplements, we recommend consulting your healthcare provider to ensure proper dosing and avoid excessive calcium intake.
