I heard Strontium is unsafe. Is that true?

No. It’s totally safe. In a 7-year clinical trial, participants taking Strontium Boost & AlgaeCal Plus (Bone Builder Pack) saw consistent bone density increases year after year—with zero reported adverse side effects.

How is AlgaeCal Bone Builder Pack different from other algae calcium supplements?

It’s the ONLY calcium supplement in the world clinically supported to increase bone density. And that’s also why AlgaeCal is the ONLY calcium supplement that offers a results-based promise.

What about side effects?

The ingredients in AlgaeCal Bone Builder Pack are easy to digest and gentle on your body. In a 7-year clinical trial researchers found “no evidence of adverse side effects.” *J Am Coll Nutr, 2016

What’s the difference between AlgaeCal, AlgaeCal Plus, & Bone Builder Pack?

AlgaeCal is for those who want to stop bone loss. AlgaeCal Plus is for those who want to increase bone density. And the Bone Builder Pack? It’s for those who want to increase bone density in just 6 months—guaranteed.
