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.
