Your Stronger Bones For Life Guarantee

We guarantee that AlgaeCal’s Bone Builder Pack will increase your bone density—or your money back. Our unique formula of 16 bone-supporting nutrients begins working from day one, and you’ll see measurable improvement on your DEXA scan within six months.

This guarantee lasts a lifetime. With every DEXA scan, your bone density should continue to improve. If it ever doesn’t, we’ll refund every penny you’ve spent since your last scan.

Skeptical? Good. So are we.

Our calcium supplement isn’t just talk — it’s proven. Three independent, peer-reviewed human clinical studies back it, and thousands of DEXA scans across all 50 states confirm the results.

Still skeptical? Good. Check the studies, review the ingredients, and watch real customer results on YouTube (“AlgaeCal reviews”).

Because when something truly works, it stands up to scrutiny.

The science is real. The results speak for themselves.

Clinically Supported

AlgaeCal has been studied in three human clinical trials conducted by researchers from leading institutions including Harvard Medical School, Georgetown University, and the University of Texas. The conclusion was the same across all three:

AlgaeCal is the only calcium supplement ever shown to increase bone density‡.

Plant-Based Calcium

Most Natural Calcium Supplements are Made From Rocks

AlgaeCal is different. It's made from organic marine algae — mesophyllum superpositum - a plant-based source that naturally contains all the bone-supporting minerals your body needs to stop bone loss and increase bone density.

    • Yea For AlgaeCal

      I highly recommend AlgaeCal. I was diagnosed with severe osteoporosis in 2001 and started taking AlgaeCal. Since then, my scans have said normal bone densiity or osteopenia. I have had no side effects and will keep taking AlgaeCal.
