INCREASE  BONE  DENSITY  EVEN  FASTER

Stimulates Bone Building

Meet one of nature's "miracle" minerals!

On average, when taken with AlgaeCal Plus as part of our Bone Builder Pack, Strontium Boost helped triple bone density increases, as compared to people taking only AlgaeCal Plus.

All-Natural

Naturally found in soil, food, and your bones

Strontium is the only natural material on earth shown to stimulate bone- building cells, while slowing down overactive bone- resorbing cells.

Safe

All-natural, safe, and a critical ingredient in our bone

The all- natural strontium in Strontium Boost is strontium citrate and it’s safely absorbed the same way as calcium. Unlike synthetic strontium, our strontium supplement is completely safe for human consumption.

Guaranteed Results

Guaranteed to increase bone density

Increase your bone density in just 6 months when you take Strontium Boost with AlgaeCal Plus! Together they make up our Bone Builder Pack.

THE NATURAL STRONTIUM

Strontium Citrate Helps With Healthy Bone Remodeling 

Strontium is a natural trace mineral in our soil. And citrate means citric acid from fruits like lemons and oranges. With our easy to swallow capsules, Strontium Boost combines strontium with citrate because citrate lowers our body's acid levels.

High acid levels trigger rogue bone cells to eat away at healthy bone. And that accelerates bone loss! Strontium is very similar to calcium, absorbed the same way as calcium, and is a critical ingredient in our bones.

THE QUICKEST WAY TO BUILD NEW BONE

Strontium Triples The Results From Calcium 

Strontium is the only substance on earth shown to stimulate bone-building cells while slowing down overactive bone-resorbing cells. So much so, that our clinical studies showed Strontium Boost helped AlgaeCal Plus triple the bone density increases of AlgaeCal Plus alone. Take our calcium & strontium supplements together as the Bone Builder Pack, and you can increase your bone density in just 6 months!

     Strontium Boost 

    I’ve heard that strontium isn’t safe. Is that true?

    Some people have read scary headlines about strontium and worry it could cause heart problems or blood clots. But here’s the truth: those warnings come from a drug called strontium ranelate. Not the natural mineral we use.

    The Source of the Confusion

    - Strontium ranelate was a synthetic prescription drug used in Europe for osteoporosis.

    - Early studies showed impressive bone density gains, but later trials revealed a small increase in heart attacks, strokes, and blood clots.

    - Regulators restricted its use in 2014, and it was eventually pulled from the market in 2017.

    - These events, and the media coverage around them, created the myth that all strontium is unsafe.

    The Form We Use: Strontium Citrate

    - Strontium citrate is completely different.

    - It’s a natural mineral salt—strontium is already found in small amounts in vegetables like broccoli, carrots, and potatoes, and “citrate” is a natural agricultural product.

    - This is the form used in Strontium Boost, and it has been studied for years with no cardiovascular risks.

    - In one 7-year study published in The Journal of the American College of Nutrition, people taking strontium citrate with a plant-based calcium supplement gained bone density every year with no safety concerns on blood tests.

    Bottom Line

    Strontium ranelate (the drug) and strontium citrate (the mineral) may sound alike, but they couldn’t be more different.

    - Strontium ranelate = synthetic drug, linked to heart risks, no longer on the market.

    - Strontium citrate = natural mineral, clinically supported to safely support bone density.

    When you see the name Strontium Boost, you can be confident it contains strontium citrate only—no drug ingredients and no ranelate.

    Does Strontium Boost artificially inflate DEXA results?

    Yes and no. Strontium acts a lot like calcium. So your body will naturally use some of it when building new bone. Over time, about 1 in every 10 calcium ions in your bones can be filled by strontium instead.

    Here’s why that matters: strontium is heavier than calcium. A DEXA scan measures mineral weight to estimate bone density, so the extra weight of strontium can make the scan look about 8–11% higher than the true calcium content.

    But that doesn’t mean the gains are fake. So if your scan shows a 10% increase, the “strontium effect” might account for a few percent of that overall increase. But that doesn’t change the fact that you’re still increasing bone density. Think of it this way: if your DEXA scan shows a 10% increase, and you adjust for the 8–11% overstatement caused by strontium’s weight, you’re still left with a real improvement of roughly 9%.

    So yes, the numbers may be slightly inflated. But your bones are still getting stronger. And that’s exactly what you want.

    Does Strontium increase bone density?

    Yes. Strontium actively builds stronger bones 

    When you take Strontium Boost, it supports bone in two key ways:

    1. Stimulates bone-building cells (osteoblasts) 

    2. Slows bone-breaking cells (osteoclasts)

    This double action—more building, less breakdown—means you build more bone in less time.

    In human clinical studies, participants taking AlgaeCal Plus alone increased bone density by an average of 1.3% per year. However, when AlgaeCal Plus was combined with Strontium Boost, bone density increased by an average of 3% per year. 

    And the best part? Many study participants saw these increases in as little as six months.
