Our Mission

Building Stronger Bones, Naturally - For Life.

At Natural Option USA, we believe the body is built to thrive — when nourished with the right support. For over 25 years, our mission has been clear: to create science-backed, plant-based calcium supplements that support bone health naturally. Our flagship formula, OsteOrganiCAL^®, is powered by red marine algae — a sustainably harvested seaweed from the Atlantic Ocean. This natural source delivers highly absorbable calcium, magnesium, and 70+ trace minerals in the form your body recognizes and utilizes best.

Our History

From Discovery to Daily Wellness

In the 1990s, researchers in Brazil uncovered the remarkable benefits of marine algae for bone health. Unlike traditional rock-based calcium — which the body absorbs poorly — this plant-based source offers naturally bioavailable calcium with a 95% absorption rate. Seeing the potential to make this breakthrough accessible, we founded Natural Option USA. As one of the first brands to introduce algae-based calcium in the U.S., we’ve spent over two decades refining our formulas to deliver superior, natural bone support.
