    Traditional Calcium Isn't Worth The Side Effects

    Heart Attacks

    Traditional calcium comes from rocks. And your body wasn’t designed to digest rocks. So what happens? Most of it doesn’t absorb. Instead, it floats around in your bloodstream—looking for a place to settle. And too often it lands in your arteries. That’s called calcification—and it can lead to clogged arteries and heart attacks. That’s why plant-based calcium is better. It’s easy to absorb and goes where it should—your bones, not your arteries.

    Digestive Issues

    Traditional calcium comes from rocks, which your stomach isn’t built to process. So when you take calcium from sources like limestone or marble, it’s tough for your body to break down. That’s why rock-based calcium can cause constipation, bloating, and gas—especially if you’re already prone to digestive issues. AlgaeCal is different. It’s plant-based and naturally absorbable, so you get stronger bones—without the stomach trouble.

    Kidney Stones

    When you take calcium from sources like limestone or marble, your body struggles to absorb it properly. What doesn’t get used can end up in your kidneys, where it mixes with other compounds and forms painful kidney stones. And you don’t want that. Plant-based calcium, like AlgaeCal, is a whole different story. It’s naturally absorbable and works with your body, so it goes where it’s needed—your bones—not your kidneys.

    Too Few Minerals

    Most calcium supplements are just calcium with a sprinkle of vitamin D and magnesium. But that’s not enough. Why? Because bone loss isn’t just a lack of calcium—it’s a loss of all the minerals that keep your bones strong. Studies show your bones need 16 essential nutrients. And calcium? It’s just one of them. That’s why AlgaeCal is better. It provides all 16 of the clinically supported bone-building nutrients.

    The Only way to increase your bone density is with 16 essential nutrients.

    The unique combination of these minerals and vitamins is clinically supported to increase bone density within 6 months.

















    This Rare Algae Contains All 16 Bone-Building Nutrients

    Scientists from Harvard, Georgetown, and Michigan State University agree: this unique algae is the only calcium source clinically proven to increase bone density.

    Stronger Bones In Less Time

    AlgaeCal has all the nutrients your bones need. But bones grow slowly. That’s why people love Strontium Boost. Strontium does something that no other mineral can do. It naturally accelerates bone building. Multiple studies show that if you take Strontium Boost alongside your AlgaeCal, you’ll triple your bone density increases. That means you get stronger bones in less time.

    “But I heard that strontium is unsafe.” 

    When people say that strontium is unsafe they’re thinking of a chemical version of strontium, called strontium ranelate - and we wouldn’t let that within a million miles of AlgaeCal. We use strontium citrate, which is completely safe. In fact, strontium is an earth mineral that’s naturally found in many of your favorite vegetables like lettuce, carrots, and potatoes.
