AlgaeCal Plus Overview

AlgaeCal PlusAlgaeCal 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.

AlgaeCalAlgaeCal 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.

USDA Organic symbol


  • Studies show taking calcium with meals increases absorption.
  • For prevention or maintenance – take 3 capsules per day.
  • For bone growth – take 2 capsules in the morning with breakfast and 2 with your evening meal.

Important Dosing Instructions if you are also Taking Strontium Boost

Do not take strontium together with calcium because these two chemically similar minerals compete at the absorption sites. Either take your strontium first thing in the morning (2 hours before breakfast), or 3 hours after the last meal of the day. The most common daily regimen is to take 2 AlgaeCal Plus caps with breakfast and 2 with dinner, then take 2 Strontium Boost before bed (no need to take strontium with food).

How Much Calcium Do You Really Need Each Day?

The daily target is 1200 mg per day of calcium intake from food and supplements combined for low bone density. An average person who consumes dairy products gets 500 – 700 mg of calcium from daily diet, so you would need to supplement 500 – 700 mg of calcium. Each AlgaeCal Plus capsule contains 180 mg of calcium. So 3 capsules of AlgaeCal Plus = 540 mg calcium. Four capsules of AlgaeCal Plus is 720 mg calcium. The clinical studies resulting in bone density increases were based on participants taking 4 capsules per day.

Drug Interactions

Calcium supplements, including AlgaeCal, should be taken at least 3 hours apart from the following drug classes to avoid interaction:

  • Antibiotics
  • Bisphosphonate bone drugs
  • Some heart medications
  • Thyroid medications such as levothyroxine
  • Water pills
  • Iron supplements
  • Strontium supplements

Vitamin K, including K2-7 found in AlgaeCal Plus, may interfere with anti-coagulant drugs. This drug interaction information is just a brief overview. Always check with your doctor for details about possible interactions between AlgaeCal products and your medications. In some cases calcium reduces the effectiveness or required dose for certain medications. Often the solution is to take calcium and the medication at a different time of the day. Your doctor should be consulted if you have any questions whatsoever.

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.

Measurable improvements always appear at 6 months from when you start your AlgaeCal Plus and Strontium Boost program. So if your next DXA  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!
