The Science Behind Coral Calcium Marine Plus
73+ trace minerals from pristine Okinawan coral — nature's most complete mineral source.
Marine-Sourced Coral
Harvested from above-sea fossilized coral near Okinawa, Japan — one of the world's Blue Zones known for extraordinary longevity. No living reefs are disturbed.
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.
Natural pH Balance
Coral calcium is naturally alkaline, helping support the body's optimal pH balance. A balanced pH environment supports overall cellular health and vitality.
