Skeptical? Good. So are we.
If you've been let down by bold claims from supplement companiesbefore, we understand. We have too. That's why we do things differently.We didn't just say our calcium supplement increases bone density. Webacked it. With not one, not two, but three human clinical studies.These independent studies were published in peer-reviewed scientificjournals. And the results have been confirmed by thousands of DEXAscans in medical clinics across all 50 states.So if you're skeptical, we welcome it. Read the studies. Check theingredients. Head to YouTube and search "AlgaeCal reviews." Becausewhen something actually works, it doesn't mind being held to a higherstandard.The numbers don't lie.And the results speak for themselves.
Clinically Supported
AlgaeCal has been studied in three human clinical trials conducted byresearchers from leading institutions including Harvard MedicalSchool, Georgetown University, and the University of Texas. Theconclusion was the same across all three:
AlgaeCal is the only calcium supplement ever shown to increase bone density.

Frequently Asked Questions
What is AlgaeCal Plus?
What is AlgaeCal Plus?
AlgaeCal Plus is a plant-based calcium supplement made from a unique South American marine algae called Mesophyllum superpositum. These USDA-certified organic algae are sustainably hand-harvested from the ocean, gently sun-dried, and milled into a fine powder.
Unlike traditional calcium supplements, which are typically derived from rocks like limestone or marble, AlgaeCal Plus is a whole-food source of all 13 essential bone-supporting minerals: calcium, magnesium, manganese, phosphorous, nickel, silica, copper, vanadium, potassium, zinc, boron, selenium and strontium. And because it comes from a living plant, this natural mineral matrix is easier for your body to absorb and utilize.
In addition to these 13 minerals we also add full clinical doses of vitamins C, D, and K.
Clinical research published in three peer-reviewed scientific journals shows that the 16 nutrients in AlgaeCal Plus don’t just slow bone loss; they can actually help increase bone density in adults. No other calcium supplement can make this claim. Because AlgaeCal is the ONLY one that’s clinically supported to increase bone density.
What is Strontium Boost?
What is Strontium Boost?
Strontium is a mineral that is naturally found in the earth, in your food, and in your bones. Our product, Strontium Boost, contains the mineral strontium bound to citrate (think citric acid from fruit) to form (natural) strontium citrate. Strontium Boost helps with your bone remodelling process by increasing the rate of your bone building cells so that you build bone faster and at the same time, it slows down your bone deterioration. Strontium Boost is the only strontium citrate product backed by human clinical studies showing its safety and efficacy when it comes to low bone density. In fact, Strontium Boost, together with AlgaeCal Plus, is guaranteed to increase your bone density in as little as 6 months.
Do I have to take both AlgaeCal Plus and Strontium Boost?
Do I have to take both AlgaeCal Plus and Strontium Boost?
You don’t have to, but if you’re dealing with bone loss, taking AlgaeCal Plus together with Strontium Boost delivers the fastest results.
Clinical studies show:
- AlgaeCal Plus alone can increase bone density by an average of 1.3% per year.
- AlgaeCal Plus + Strontium Boost together produce an average 3% increase in just one year. And most people see results within the first 6 months.
So when you add Strontium Boost to your AlgaeCal Plus you’re going to build bone faster. That’s right. You’ll build more bone in less time.
And when you take both products together, you’re also covered by our Stronger Bones For Life Guarantee. So when you take AlgaeCal Plus and Strontium Boost, as directed, you’re guaranteed to see measurable bone density increases within six months – or your money back!

What if I have trouble swallowing the capsules?
What if I have trouble swallowing the capsules?
AlgaeCal Plus comes in size zero soft vegetarian capsules which are easy to swallow.
However, if swallowing capsules is difficult, you can gently pull them apart and sprinkle the tasteless powder into food or drinks. Semi-solid foods such as smoothies, applesauce, or yogurt work best.
Avoid mixing the powder into hot liquids above 120°F (49°C), as high temperatures can reduce the potency of vitamins C, D, and K2.
Because the powder contains a wide range of natural minerals, it is only partially water-soluble, so it won’t completely dissolve in liquid.
Does AlgaeCal Plus cause side effects such as deposits in kidneys or arteries?
Does AlgaeCal Plus cause side effects such as deposits in kidneys or arteries?
No. AlgaeCal Plus is safe and without adverse side effects. Here’s why:
- Plant-based, not rock-based: Unlike traditional calcium supplements made from limestone or marble, AlgaeCal Plus is a food-source calcium similar to the calcium found in vegetables like broccoli and kale. So your body recognizes it as food and absorbs it accordingly.
- Balanced with co-factors: Each serving provides additional magnesium, boron, vitamin K2, and vitamin D3. These nutrients work together to move calcium into your bones where it belongs, and away from soft tissues like arteries, kidneys, or eyes.
- Clinically effective at a lower dose: AlgaeCal Plus increases bone density with only 720 mg of calcium per day, the exact amount used in human clinical studies. Traditional calcium supplements often recommend 1,200 mg or more—and still only slow bone loss.
Because AlgaeCal Plus delivers the right kind of calcium, in the right balance, it strengthens bones without the risks of kidney stones or arterial calcification.
Can I take AlgaeCal Plus if I am on bone medications?
Can I take AlgaeCal Plus if I am on bone medications?
Yes. All prescription bone medications require adequate calcium to give your body the raw materials it needs to build new bone. And AlgaeCal Plus provides a clinically supported, plant-based calcium that works beautifully alongside these treatments.
That said, it’s always important to check with your healthcare provider before making any changes to your supplement routine or medical care, especially if you’re currently taking prescription medications.
Does my doctor know about AlgaeCal?
Does my doctor know about AlgaeCal?
Many doctors, especially those open to natural treatments, are already familiar with AlgaeCal. But every healthcare provider is different, and it’s always best to give them the full details yourself.
To make it easy, we’ve created a “Take It to Your Doctor” information sheet that outlines the clinical research, ingredients, and dosing. Print it out or share it at your next appointment so your doctor can give you the best, personalized guidance for your bone health.
What is the Stronger Bones for Life Guarantee?
What is the Stronger Bones for Life Guarantee?
You need strong bones for the rest of your life to enjoy, rather than endure, your golden years. With our guarantee, you can continue enjoying your favorite activities for the rest of your days.
Measurable improvements will appear at 6 months from when you start your AlgaeCal Plus and Strontium Boost program. So if your next DEXA scan is scheduled half a year or more from now, we guarantee you will see a bone density increase.
You may choose to wait for your next scheduled scan so that it is paid for by your insurance, or you may choose to pay out of pocket to check your results earlier. Either way is fine.
Just allow at least 6 consecutive months of taking the products as directed before your follow-up scan. We encourage you to take a scan every year to make sure you’re still building new bone.
IMPORTANT: Ensure you get your DEXA scan at the same clinic every time. Ideally, you’d get your scan on the same machine, too. That way, every scan is directly comparable to the last. If your follow up scan does not show an increase in your hip or spinal bone density, we refund every penny you paid us between those two scans.
Your 3 Steps to Guaranteed Bone Density Increases
1. Have a DEXA scan that is not more than 30 days old to establish a baseline measurement. (If you had a DEXA scan more than 30 days ago, your guaranteed period will launch from your next scan onward. So don’t wait! Get started building healthy new bone right now before your guarantee begins.)
2.Take AlgaeCal Plus and Strontium Boost at full dose as directed for at least six months.
3.Get your follow up DEXA scan from the same clinic as your first scan. It doesn’t matter when… six, twelve, even 24 months after you start – as long as you have continued to use your products between scans.
If your follow up scan does not show an increase in your hip or spine bone density, we refund every penny you paid us between those two scans.
