Frequently Asked Questions
What is AlgaeCal Plus?
What is AlgaeCal Plus?
AlgaeCal is a South American marine algae species,Mesophyllum superpositum(or Algas calcareas as the locals call it). This kiwi-fruit sized algae is sustainably hand harvested in the atlantic ocean, sun dried, then milled into a powder. There is no extraction process or additives used – just pure whole food calcium and minerals coming from a living plant. Watch theAlgaeCal Harvesting videohere. AlgaeCal powder is the foundational ingredient in our products,AlgaeCalandAlgaeCal Plus. AlgaeCal powder has significant advantages over traditional calcium supplements that are pure calcium becauseAlgaeCal contains all 13 known essential bone supporting minerals: calcium, magnesium, manganese, phosphorous, nickel, silica, copper, vanadium, potassium, zinc, boron, selenium and strontium. Traditional calcium carbonate and calcium citrate supplements are made from limestone and marble – and your body does not absorb rocks very well – so plant-sourced AlgaeCal has the benefit of being body-friendly and better absorbed into your bones. In fact the superfood mineral combination naturally found in AlgaeCal has been clinically supported to increase bone density in adults – but traditional calcium supplements only slow annual bone loss a little. In other words, after age 40, we typically lose 1% of our bone density every year until death – so most will become osteoporotic if they live long enough. Traditional calcium supplements slow this annual bone loss from 1% to ¾% – so it only helps a little. But AlgaeCal Plus actually increases bone density – and if taken with Strontium Boost, the combination is even more effective at increasing bone density
How many AlgaeCal Plus capsules should I take and when should I take them?
How many AlgaeCal Plus capsules should I take and when should I take them?
To maximize your bone-building, take 4 capsules of AlgaeCal Plus a day. (This was the dosage that led to the most significant bone density increases in clinical trials).
We recommend splitting the daily 4 capsule dose into 2 servings of 2 capsules throughout the day. Your body can only absorb 500mg of calcium at a time, so taking more than 2 AlgaeCal capsules in one serving would lead to unabsorbed calcium.
And finally, it’s best to take your AlgaeCal Plus with food. That’s because taking calcium with food increases how well you absorb it. When you eat, your stomach produces acid that dissolves the minerals in AlgaeCal Plus so they can be properly absorbed when they reach your intestinal tract.

What ingredients are in AlgaeCal Plus?
AlgaeCal Plus contains calcium from a marine, plant-based algae source calledMesophyllum superpositum. This algae belongs to the family of algaes known as Algas calcareas. So to make it easier to say, we just named it “AlgaeCal”! AlgaeCal has worldwide exclusive rights to this particular type of algae – and it is the only clinically backed calcium supplement in the world withhuman studiesshowing increases in bone mineral density. All other calcium has only ever been shown to slow down bone loss. In addition to this unique calcium, AlgaeCal Plus also contains magnesium, vitamin D3, vitamin K2 (in the form MK-7), vitamin C, boron and naturally-occurring trace minerals. In particular, AlgaeCal Plus contains all 13 bone-building minerals in their proper proportions that make up your bone matrix. AlgaeCal Plus is also dairy-free, soy-free, gluten-free and non-GMO!

Do I have to take both AlgaeCal and Strontium Boost?
Do I have to take both AlgaeCal and Strontium Boost?
If you are suffering from bone loss, it is best to take both AlgaeCal Plus and Strontium Boost. Together they areclinically supportedto increase bone density in as little as 6 months – at any age! They also increase your bone density at a faster rate than AlgaeCal Plus alone. For example, studies prove AlgaeCal Plus alone can increase bone density by an average of 1.3% per year, compared with an average bone density increase of about 4% per year with AlgaeCal Plus and Strontium Boost together. This is significant for those suffering from bone loss who may be experiencing more than 1% bone density loss per year. Taking the two together also gives the bone-building process a “kick start” to increase bone density safely and naturally, ensuring you have covered any potential losses.

Therefore, AlgaeCal Plus contains 360 mg of elemental calcium in two capsules (that’s 720 mg of elemental calcium in a daily dose, 4 capsules).
I have trouble swallowing pills. How big are the capsules? Is it OK to open the capsules and mix it with food/beverages?
I have trouble swallowing pills. How big are the capsules? Is it OK to open the capsules and mix it with food/beverages?
AlgaeCal Plus, AlgaeCal Basic, and Strontium Boost all use soft capsules which are ¾” long and easy to swallow. If you do have trouble swallowing them, the two-part capsules can be pulled apart. You can then sprinkle the tasteless powder into your favorite drinks and food. We recommend semi-solid foods such as smoothies, applesauce or yogurt and avoiding hot drinks as temperatures above 120 degrees Fahrenheit as it may reduce the potency of the vitamins C, D, and K2. Please note that the AlgaeCal powder is only partially water soluble due to the many natural minerals and therefore does not dissolve completely 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?
Unlike traditional, rock-derived calcium supplements, AlgaeCal has no adverse side effects such as kidney stones or arterial calcification. AlgaeCal is a natural, plant-sourced calcium that is easy for your body to absorb. It’s similar to calcium you get from eating vegetables such as broccoli, kale and peas. Some studies have shown that calcium from food sources does not increase soft tissue calcification because foods that naturally contain calcium also supply other minerals, which helps transfer the calcium directly into your bones rather than soft tissues like arteries, kidneys and eyes. Additional magnesium, boron, vitamin K2 and vitamin D3 are added into AlgaeCal Plus to optimize absorption and transport to the bone rather than soft tissues. All these factors translate to efficient absorption and placement into bone tissue. AlgaeCal is also much safer for you because it is more effective at a lower dose. At 720 mg per day of calcium, AlgaeCal Plus is increasing bone density in adults. Compare that to regular calcium supplements that have been studied at 1200 mg per day – and only slow bone loss.
Does AlgaeCal Plus cause constipation, gas or bloating?
Does AlgaeCal Plus cause constipation, gas or bloating?
The vast majority of people who experience gastrointestinal side effects from regular calcium supplements have not experienced any adverse side effects from AlgaeCal. These stomach troubles usually derive from consuming rock-source calcium, which our bodies are not designed to digest. Plant calcium contains a variety of balancing minerals including magnesium, which make it more easily digested. We recommend that you split your daily dose into breakfast and dinner time. Taking AlgaeCal with food increases absorption and reduces chances of any gastrointestinal issues.
I am petite, so do I need a full dose?
I am petite, so do I need a full dose?
The recommended daily dose is the same for each individual no matter their size because it is based on age, not weight. In fact, if you are petite, you are at a higher risk for bone density loss because you have less skeletal mass to begin with, so a full dose is recommended.
Is AlgaeCal Plus tested for contaminants? Does AlgaeCal contain Lead and other Heavy Metals?
Is AlgaeCal Plus tested for contaminants? Does AlgaeCal contain Lead and other Heavy Metals?
Great question! Actually, lead is a natural mineral like calcium or magnesium which is found in the earth, air and water. So every vegetable that grows in the soil or water has normal amounts of lead in it – the marine algae in AlgaeCal is no exception. Luckily, our bodies easily clear normal amounts of lead daily through urine, feces, and sweat.
Every batch of AlgaeCal powder is tested by a third party laboratory for microbial activity, heavy metals, mineral content and more. The final product is made in an FDA-inspected GMP (Good Manufacturing Practice) plant where the highest standards are kept.
AlgaeCal has FDA registration and Health Canada approvals. It has been on the market for 20 years and has 3 clinical studies and a toxicology study showing extraordinary safety!
Can I take AlgaeCal Plus if I am on bone medications?
Can I take AlgaeCal Plus if I am on bone medications?
Absolutely. All bone drugs require calcium supplementation to supply the needed calcium for bone building – and AlgaeCal Plus is the highest quality calcium available.
