AlgaeCal Plus Overview

AlgaeCal Plus is a natural calcium supplement where the calcium used in the formulation is derived from a special form of algae.

It is not made from limestone or marble, unlike traditional calcium supplements. One of the best features of AlgaeCal Plus is that the calcium is pre-digested calcium which means it is part of the natural life of the algae where it comes from.

It breaks down essential minerals as they are absorbed. Thus, the algae have already done the hard part, and the product is quickly and easily absorbed by the body.

Traditional calcium supplements made from limestone are difficult to digest and absorb, so most of them go to waste during digestion.

Does AlgaeCal Plus Really Work?

It is difficult to say whether the product really works or not because there is mixed feedback from people who have tried the bone health supplement. However, the larger majority of feedback is positive, saying they are satisfied with AlgaeCal Plus.

Most people are aware of the importance of calcium intake for bone health. This is why there are many products for bone health claiming to contain this or that amount of calcium.

However, most calcium supplements being sold today are made from limestone or marble.

If you check your calcium supplement and the supplement facts include calcium carbonate, calcium citrate, or some other name, it is simply ground rocks. Basically, it is like you are consuming rocks.

Most calcium supplements are big and difficult to swallow. It may even cause constipation or digestive discomfort. However, it can also lead to serious side effects.

Two major studies published in British Medical Journals which involved thousands of participants indicate that traditional limestone calcium supplements can increase the risk of a heart attack.

The studies have found that large quantities of non-food calcium intake can cause some of the minerals to be deposited as arterial plaque. The calcified arterial plaque can even clog arteries increasing the risk of heart attack and stroke.

What is the Iodine Level in AlgaeCal Plus?

According to the manufacturer, each capsule of their supplement contains only 4.4 mcg of iodine, and the product is made from algae, not from a sea vegetable such as kelp or seaweed.

According to a laboratory test, AgaeCal Plus only contains 7.33 parts per million iodine. This translates to a total of 17.5 micrograms of iodine in the daily recommended dosage of 4 capsules (4.4 micrograms per capsule).

In comparison, 100 grams of seafood contains 66 micrograms of iodine and 100 grams of vegetables contain 32 micrograms of iodine. This means that the level of iodine in the product is at a very safe level.

Your Guide to AlgaeCal Plus (Video Credit: YouTube)

Is AlgaeCal Plus Just Another Calcium Supplement?

As per AlgaeCal Plus Reviews, AlgaeCal Plus is just another calcium supplement that contains calcium carbonate. The composition is very different since calcium carbonate is a calcium ion that is connected (attached) to a carbonate molecule.

It is 40% elemental calcium and 60% carbonate. On the other hand, AlgaeCal has calcium ions that are attached directly to carbonate molecules, sulfate molecules, chloride molecules, etc. It also contains 13 other essential minerals that are known to support bone health plus a number of organic phytonutrients.

It is 30% elemental calcium and 70% other nutrients. Clinical studies indicate that AlgaeCal Plus is also more effective and considerably outperforms calcium carbonate since it has 200 to 400% greater mineralization and proliferation of bone-building cells compared to calcium carbonate.

AlgaeCal Plus FAQ’s

Q: How to take AlgaeCal Plus?

A: For maintaining healthy bones, it is recommended to take 3 capsules a day. It is advisable to take 2 capsules in the morning with food and 1 in the evening also with food.

If the user is trying to grow bone due to osteoporosis, osteopenia, or any reason, the recommended intake is 4 capsules divided into 2 doses also taken in the morning and evening with food.

Q: Does AlgaePlus Increase Bone Mass?

A: According to two separate published clinical studies, AlgaeCal Plus can increase bone mass. The studies have shown that in a period of 6 months to 1 year, bone density can be increased with the use of the revolutionary calcium supplement.

However, a special clinical formulation is necessary to increase bone mass so instead of just taking 3 capsules daily, you will have to take 4 capsules. Also, the user has to take another product from the same company called Strontium Boost.

Q: Does AlgaeCal Plus Offer a Guarantee?

A: It comes with a 180 day double your money guarantee. If the user gets a DEXA scan to assess the bone mineral density and takes the product together with Strontium Boost for 180 days, then has another DEXA scan showing no improvement in bone mineral density, double of the 6 months purchase of AlgaeCal Plus will be refunded.

Q: Is AlgaeCal Plus a Scam?

A: There is no indication that AlgaeCal Plus is a scam since it is based on science, and the product is actually clinically tested and proven to be effective.

There are many articles online saying it is just a scam because it is nothing more than ordinary calcium carbonate. However, the product is proven to contain a matrix of minerals and other organic matter proven to be important for bone health and effective in helping increase bone mass.

There are a growing number of researches showing that the new calcium supplement derived from algae is superior to traditional calcium supplements made from limestone.

Q: What are the Side Effects of AlgaeCal Plus


  • Elevated blood pressure
  • Upset stomach and vomiting
  • Itchiness and inflammation
  • Insomnia and nausea

Q: Is AlgaeCal Plus safe?

A: Yes. However, avoid taking calcium supplements less than three hours before or after other treatments such as antibiotics, cardiac medications, thyroid medicines, iron supplements, and others.

AlgaeCal Plus Reviews – Final Verdict

AlgaeCal Plus is a good supplement for bone health. It can also be used together with another supplement if the user wants to increase bone mass.

It is clinically proven to be effective and even comes with a 180-day double-your-money-back guarantee which is pretty impressive. This is one of the better calcium supplements being sold today.

Bone development occurs every day of your life, but the pace of losing and growing bone differs depending on age. Building bone mass early in life through exercise, a healthy diet rich in calcium, and supplementation may help delay symptoms associated with osteoporosis. Bone health supplements should be determined based on its: potential to promote increased bone density, potential to reduce bone loss, and potential to Maintain Healthy Bone Support*. The ingredients should be backed by clinical studies and proven to promote overall bone health.

Below you'll find some of the most effective bone health supplements on the market today, in our opinion.

  1. Debi

    DECREASE in Bone Density
    After using the AlgaeCal Bone Builder Pack for a year, my repeat DEXA scan showed a decrease in bone mineral density in all 3 areas tested! They refused to honor their money-back guarantee.
  2. Martha Walker

    AlgaeCal and Strontium Boost did not help
    I took AlgaeCal and Strontium Boost for 2 years as directed to try to improve my bone density results. My bone density level decreased over those 2 years and osteoporosis is more advanced. I will now be taking Prolia injections.
  3. Patricia Holmes

    Seeing is believing
    I am taking Algae Cal, which I have now been on since July 2019. On my bone density test, which is free for seniors over 65 through Medicare, my bone density increased and shocked my doctors. They asked what I was doing this past 4 years differently. I am reversing my bone loss.

    I have tests to prove it. I have osteoporosis of the spine which has gone from 3.6 in 2015 to 2.9 in 2020 and 2.7 in 2022. Slightly improving instead of getting worse. I have Osteopenia in the hips and neck, which causes me some pain. But they have improved as well. The increase in bone density has to be the products I am taking.

    And the only thing I am doing differently is taking Algae Cal. I no longer go on walks. And for the last 2 years no exercise at the YMCA for the bones because of COVID closures. I do take other vitamins and minerals but I was doing them for the last 10 years, and that did not move the markers. Only when I added the Algae Cal did this make a change.

  4. Martha Reed

    Recommend this to everyone, to try.
    For 14 or 15 years, each DEXA scan was progressively getting worse. I react badly to so many medications, I was refusing the injections and various meds recommended by my doctor. I read about AlgaeCal and decided to try it. I’m only allowed a DEXA every 2 years under my insurance, so I did have to wait to see if it worked. Had my DEXA a month or so ago and WOW! For the first time in all those years, my scan showed an improvement! I am thrilled!
  5. Sarah Stephenson Jusko

    New results after Dexa scan!
    After watching my Dexa scan get worse over the years and finally last year revealing osteoporosis, I decided to try AlgaeCal Plus and Strontium Boost, as it was guaranteed to work. Today I received great news! My Dexa scan last week shows a 6% improvement in bone growth. Still osteopenia, (thank you, Mom and Grandma) but improvements in the right direction. I have just reordered another year of AlgaeCal Plus and Strontium as it is working!
  6. Diana Lamb

    AlgaeCal Plus/Strontium really works
    I highly recommend this product as it has worked for me. The bone density in my spine increased 21% and in my hips a 15 month period taking me from severe osteoarthritis to osteopenia. My doctor was very pleased and told me to continue with the product which I fully intend to do.
  7. Dolores Mcalenon

    Need some advice
    I read some reviews that told about certain vitamins or minerals that others take with Algaecal and can’t find it again. For example, what about iron or folic acid, should they be taken with Algaecal or later or not at all?

AlgaeCal Plus Ques and Ans

  • Q: I have a scoliosis that is progressing, is more painful, and more pronounced at this time. would you advise me to try to use of Algaecal plus?

    A: It is recommended to speak with a healthcare professional to determine the best course of action for your specific condition. They can evaluate your symptoms and medical history and determine if Algaecal Plus is appropriate for you. They can also advise on the potential benefits, risks, and side effects of using this product.

  • Q: Can AlgaeCal Plus be used for arthritis?

    A: Algaecal Plus supports bone health, balances blood pressure and reduces colorectal cancer. However some of the Algaecal plus reviews say, it also helps to deal with arthritis problems.

  • Q: Do I have To Take Both AlgaeCal Plus and Strontium Boost?

    A: Both products should only be taken if the user is trying to grow bone due to osteopenia, osteoporosis, or high risk for osteoporosis. However, for maintaining bone health only, the user doesn’t have to take Strontium Boost.

    Q: Can I take AlgaeCal Plus and StrontiumBoost when taking Xarelto?

    A: Calcium is like a double-edged sword; it is the best agent that strengthens the bones and teeth, and on the other hand, it also plays an important role in blood clotting, helping muscles contract. AlgaeCal Plus and StrontiumBoost are packed with Calcium and Strontium Citrate. So you can't take Xarelto as the influence AlgaeCal Plus and StrontiumBoost will nullify the effects of Xarelto.

  • Q: I have been taking AlgaeCal Plus with Strontium Boost for two years. It is working great with excellent results on my Dexa Scan. I have just been told by a friend that it contains lead. There is so much information on the internet that I have not been able to find where it contains 1.5 mcg of lead. Is this true?

    A:Yes, AlgaeCal powder is USDA Certified Organic which means the harvest area and surrounds are inspected regularly for possible pollutants. Also, each lot of AlgaeCal is tested for heavy metal contamination, bacteria, molds, and more. AlgaeCal Plus is made in an FDA inspected GMP plant where the highest standards are maintained. One of the naturally occurring AlgaeCal minerals is lead and there is 1.4 mcg of lead in 4 capsules of AlgaeCal. This amount falls well within the safety standards of the US FDA, EPA, Health Canada, and World Health Organization. The range of allowable daily safe lead intake levels ranges in these organizations from 20 – 250 mcg per day. So AlgaeCal’s lead content is an insignificant fraction of the allowable limits. Every vegetable that grows in the soil or water has normal, safe amounts of lead in it – and the marine algae in AlgaeCal is no exception. Plus, your body clears normal amounts of lead daily, through urine, feces, and sweat, unless there is a sudden spike that surpasses your body’s capacity to clear. The results of a recently completed 7-year study show extraordinary safety via a panel of 45 blood chemistries. Click HERE to read the study.

  • Q: Can I take AlgaeCal Plus while on Eliquis?

    A: As a general rule of thumb, it is best to separate any prescription medication by at least 2-3 hours from when you take AlgaeCal Plus. Calcium supplements can interact with a variety of medications, so it's important to know what you're taking.

  • Q: I have been trying to use the strontium plus but it gives me diarrhea. I went down to just one pill but still have the problem. Is there another product that would do the job without the diarrhea?

    A: Some people may experience diarrhea as a side effect of taking the Bone Support Supplement. However, this is not a common side effect and could be due to other factors such as dietary changes or an underlying medical condition. It is best to speak with a healthcare professional to determine the cause of diarrhea and whether it is related to taking Bone Support Supplement. According to some research, we found that AlgaeCal Plus is the best Bone Support supplement. As well as according to customer reviews we didn't get any side effect review like diarrhea.
