We began with a revolutionary idea. Bone loss doesn’t have to happen. Yes, traditional calcium can slow it down. And that’s definitely a step in the right direction. But Dean Neuls, our founder, wasn’t satisfied with merely slowing bone loss. He wanted to stop it in its tracks. And better yet — actually increase bone density‡*.
So he went searching for a solution. He found it on a beach in South America: a rare ocean algae naturally rich in all 13 minerals your bones need. That discovery changed the calcium industry forever. And transformed the lives of thousands of women and men.
AlgaeCal became the only calcium supplement clinically supported to increase bone density.
Here’s the truth: there are hundreds of calcium supplements on the market. Some are made from rocks. Others from algae. But they all share one thing in common—not one has a single clinical study showing it can increase bone density. Not one!
And that’s what makes AlgaeCal unique. It’s the only calcium supplement in the world clinically supported to increase bone density. No other calcium supplement can make that claim. So if your goal is stronger bones, AlgaeCal isn’t just an option—it’s the only option.

So if you’re worried about your bones, take heart: you can increase your bone density. In fact, we guarantee it.
That’s right. Of all the calcium supplements on the market, ours is the ONLY one that guarantees results. So when you take our popular Bone Builder Pack as directed, we guarantee you’ll see an increase in your bone density within 6 months. And if you don’t? We’ll refund every penny.
Imagine this: just 6 months from now, you could be calling your family and friends with the good news—your bone density has gone up!
Others have done it. We’d love for you to be next!

Frequently Asked Questions
What is AlgaeCal Plus?
What is AlgaeCal Plus?
AlgaeCal Plus is a plant-based calcium supplement derived from marine algae. It is uniquely formulated not only to provide essential bone-building minerals (calcium, magnesium, and 70+ trace minerals) but also to include vitamins D3, K2, and C to help direct calcium to the bones and support the bone remodeling process.
How is AlgaeCal different from other calcium supplements (like calcium carbonate or citrate)?

Unlike rock-derived calcium, AlgaeCal is a whole food, plant-based source. Its structure is naturally porous, making it easier for the body to absorb. Crucially, it is part of a clinically supported regimen shown in studies to increase bone mineral density, whereas some other calcium forms may only aim to slow bone loss.
