Guarantee Exceptions

1. Drug Use: many prescription drugs interfere with bone density. Call us toll free to learn if your prescription excludes you from our guarantee. 1.877.792.5690
2. Early Stage Menopause: for the first five years of menopause, hormone shifts can offset the bone building benefits from our products.
If you are in either of these exceptions, the nutrients in our products are EVEN MORE IMPORTANT to take to minimize your bone loss! And often you will STILL increase your bone density in spite of medication use or early menopause.

Bone Builder Pack

AlgaeCal Plus and Strontium Boost are now available as convenient Bone Builder Packs, providing your bones with all the nutrients they need at an economical cost.

The most popular bundle is our six month bone builder pack, which includes 6 bottles of AlgaeCal Plus and 6 bottles of Strontium Boost. To increase bone density, the daily dose is 4 capsules of AlgaeCal Plus per day, just like in clinical studies. So you need 6 bottles for a six month supply.

Together, AlgaeCal Plus and Strontium Boost are GUARANTEED to increase your bone density in as little as six months! But remember, bone building is an ongoing process (on average, you continue to lose about 1% of your total bone mineral density every year!) requiring all the nutrients your bones need for a lifetime. So our best best possible pricing is with the 12 month Bone Builder Pack. See our guarantee.

AlgaeCal Plus
AlgaeCal Plus Overview

AlgaeCal marine algae supplies a full spectrum of calcium, magnesium, and over 70 trace minerals. Plus, clinical doses of vitamin D3, vitamin K2, boron, and additional magnesium have been added to the algae powder to make AlgaeCal Plus your complete, multi-nutrient approach to bone building.

Algas Calcareas marine algaeAlgaeCal wild-harvested, plant-sourced calcium is derived from a South American marine algae called Lithothamnion superpositum (or Algas Calcareas as the locals call it). The entire kiwi-fruit size algae ball is hand harvested, sun dried, then milled into a powder. There is no extraction process or additives used – just pure whole food.

Pre-Digested Calcium is Body-friendly

The AlgaeCal plant draws calcium and 70 other minerals from sea water and pre-digests it for you much like a carrot or potato root breaks down the in-edible rock minerals in soil converting them into a useable form your body recognizes as food. Most traditional calcium supplements are made from pulverized limestone or marble.

AlgaeCal plant-digested calcium is so body-friendly that it dissolves in 30 minutes using USP standard tests simulating stomach conditions proving it is very bio-accessible.

Algas Calcareas is Certified Organic and Kosher

USDA Organic symbolOrganic certification attests to both the purity, and to the sustainability of this algae. A third party organization called IBD Certificacoes has certified that the harvest area is free of pollutants and that the harvest levels are allowing this resource to regenerate. IBD is held responsible by the USDA and IFOAM (International Federation of Organic Agriculture Movements) ensuring that AlgaeCal is the highest quality, wild-harvested ingredient. See Organic Certification for Algas Calcareas.

Algas Calcareas is kosher certified through Natural Food Certifiers. See Kosher Certification.

The “Plus” in AlgaeCal Plus

AlgaeCal is more than a plant-source, whole-food calcium supplement. It’s a multi-nutrient approach to your bone health that includes full, clinically supported doses of:

Vitamin D3 and vitamin K2
These two fat soluble vitamins work synergistically to support calcium absorption and distribution to your bones
The Western diet tends to be magnesium deficient, so to make up for this shortfall AlgaeCal Plus provides you with the 2:1 calcium to magnesium ratio that is optimal for bone health.
Several studies show boron playing a crucial role in bone health at 3 mg per day, which is the exact amount added

These additions make AlgaeCal Plus the most complete calcium supplement on the planet.

Strontium Boost - Single Bottle
Strontium Boost Overview

Strontium Boost is composed of strontium citrate. The earth element strontium (naturally found in small amounts in your food) is combined with citrate (common in fruit) to bond the two into strontium citrate. Strontium Boost taken together with AlgaeCal Plus is guaranteed to increase your bone density in six months.

Strontium is a similar mineral to calcium in many respects and is naturally present in trace amounts with around 100 micrograms in every gram of your bone.

Various forms of strontium have been tested on bone strength since the 1950`s with positive bone building effect, so strontium citrate was added to AlgaeCal in some of the clinical research groups with excellent additive results. Depending on formulation, study participants increased bone density by 3 to 4%.

Research shows that strontium may overstate DXA scan bone results anywhere from 8.5%- 11.2%, maximum. However, the positive results in the strontium studies (including AlgaeCal studies) are still outright increases in bone density in older adults who should be losing bone. To put it in perspective, if you gained a modest 1% after taking strontium and you reduce that score by 10%, you still gained .9% of bone density.
Strontium drug studies have also shown reduced fracture risk independent of bone density readings. In other words, while strontium may affect your DXA results some, the important thing is that it improves your bones’ quality and lowers risk of fractures. And that’s the goal, isn’t it – healthier bones that are more resistant to fracture!

AlgaeCal Plus and Strontium Boost should be taken separately, at least 2-3 hours apart for optimal absorption. These two minerals are chemically similar and therefore compete at the same absorption sites. The most common daily regimen is to take 2 capsules of AlgaeCal Plus with breakfast and two with dinner, then 2 capsules of Strontium Boost before bed. (Strontium does not need to be taken with food).

7 year guarantee sealWhen you take AlgaeCal Plus and Strontium Boost accordingly– we guarantee you will see increased bone density in EVERY follow-up DXA scan you have while using these 2 products – or we will refund every penny you paid for our products between your scans. This guarantee extends to every scan you have for the next 7 years!

Too Good to Be True?

Since no other calcium company, no drug, and no doctor guarantees you will increase bone density even for one year, why should you believe our 7 year guarantee?

Because we have been offering this guarantee since 2006. Because 19,473 customers like you have ALREADY built stronger bones…and only one person didn’t see the results we guarantee! And because our products are clinically supported to increase bone density over a 7 year period – they just work.

Measureble improvements always appear at 6 months from when you start your AlgaeCal Plus and Strontium Boost program. So if your next DXA (or DEXA) scan is scheduled half a year or more from now we guarantee your 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 for us. Just allow at least 6 months of taking the products as directed before your follow up scan.

In other words, “scan to scan to scan” improvements MUST be yours for the next 7 years!

What You Need To Do

Doctor and patient look at DXA scan results

  1. Have a DXA scan that is not more than 30 days old to establish a baseline measurement. (If you had a DXA 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 these two products at full dose as directed for at least six months.
  3. Get your follow up DXA 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 and/or spinal bone density, we refund every penny you paid us between those two scans.

You can repeat this process of increasing bone, guaranteed, from scan to scan, for the next 7 years! (Because our products are clinically supported to increase bone density over a 7 year period.)  At that point, we’ll be happy to repeat the guarantee. That’s how confident we are that you will see a bone density increase with every subsequent scan!  You are automatically extended!

Your satisfaction is also guaranteed for as long as you take our products. You must be 100% satisfied, or you get your money back. Period. If you need anything at all please call our amazing customer superstars toll free at 1-800-820-0184.


  1. Current Prescription Drug Use. Studies show that a wide range of prescription drugs, including bone drugs, interfere with natural bone density increases. You may take drugs now that impede AlgaeCal Plus and Strontium Boost from increasing your bone density. To learn if your prescription is excluding you from this guarantee, please call toll free 1-800-820-0184.
  2. Early Stage Menopause. If you are in the first five years of menopause, your hormone balance may cause a dramatic drop in bone density. So even the great nutrients in AlgaeCal Plus and Strontium Boost may not be able to offset the loss. So women in this phase of life are excepted from the Guarantee. IMPORTANT NOTE: Even if you fall into one of the guarantee exceptions, AlgaeCal Plus and Strontium Boost is still your smartest choice because it is the ONLY nutrient combination that is clinically supported to increase bone density in adults. If you are taking medications or are in early menopause, you need every nutritional advantage you can get. Often, exempted customers STILL increase their bone density!
