AlgaeCal Plus Review: Does It Really Work For Bone Health?

Calcium is a vital mineral that is necessary for the health and structure of your bones.

If you don’t get enough calcium, your body won’t be able to build and maintain strong bones. Because your bones and teeth store over 99% of the calcium in your body (1).

Your bones and teeth will subsequently lose calcium as a result, becoming brittle and weak. Your doctor might advise calcium supplements if you have osteoporosis as a result of this.

After menopause, women are more likely to develop osteoporosis, and as a result of developing osteoporosis, older women are much more likely to exercise or take calcium supplements.

Moreover, choosing a high-quality calcium supplement can be difficult for many of us, especially if we don’t know what to look for.

In this review, we dive deep into one of the most popular calcium supplements, AlgaeCal Plus, which focuses on increasing bone density with its plant-based formula.

We’ll also see how it holds up in terms of supporting your bone health. Is this supplement as effective as compared with their best alternative options? Read on to learn more about the AlgaeCal Plus review, including its benefits and drawbacks.

Having said that, it’s time to dive in.

What is AlgaeCal Plus?

AlgaeCal Plus is a bone-health supplement containing plant-based calcium that prevents bone loss and promotes bone formation. 

This supplement contains a potent plant-based serving of 16 bone-supporting nutrients.

They come in veggie capsule form, making them easy to take on a daily basis. They also claim that the plant-based algae in AlgaeCal Plus contain all of the nutrients your bones require and that your body can easily absorb them.

Not only do they provide detailed information on the clinical evidence, but they also show that it’s ingredient sourcing.

This “Plus” in AlgaeCal likewise means that it contains additional vitamins D3, C, and K2, which can aid in calcium absorption and the prevention of conditions such as osteoporosis, or bone loss.

Instead of generic Health Consultants, they have collaborated with the world’s leading bone-health scientists to assist in the development of this product, and you can also talk or speak to their experts.

AlgaeCal Plus Manufacturer

The bone health supplement AlgaeCal Plus is a product from AlgaeCal Inc. The manufacturer claims itself to be the leader in everything related to bone health. 

Dean Neulus, the founder of AlgaeCal, wanted something that can actually help build new bones. While traveling on the beach of South America, he found an ocean Algae, that has all 13 essential minerals known for supporting healthy bones. 

AlgaeCal is the only supplement that is supported clinically to stop bone loss and increase bone density for people of all age groups.

The company also has other products at their store for you including AlgaeCal, AlgaeCal Strontium support, and Triple Power Omega 3 fish oil.

On its BBB page, AlgaeCal is rated A+ with almost no complaints. However, the business isn’t BBB accredited. 

Evaluation Of AlgaeCal Plus Ingredients

Vitamin C (as calcium ascorbate), 25 mg 

Calcium ascorbate is a type of vitamin C that is frequently used to treat or prevent vitamin C deficiency in people who do not get enough of the vitamins from their diets.

Vitamin C is found in foods such as peppers, kiwi, strawberries, tomatoes, and Brussels sprouts. These vitamins also contain ascorbic acid, which is required for collagen formation and bone health.

A vitamin C deficiency can result in muscle weakness, scurvy, tooth loss, and joint pain. According to a 2013 study on vitamin C and its Disease Prevention and Cure, it plays an essential role in bone formation, wound healing, and maintaining healthy gums.

Another 2020 literature review on the role of Vitamin C in the development and treatment of osteoporosis discovers that Vitamin C may also be effective in maintaining bone health.

You must consume enough Vitamin C to maintain the health of your skin, cartilage, teeth, bone, and blood vessels, especially if you are recovering from menopause and have compromised bone structure.

Vitamin D3 (as cholecaciferol), 800 IU

Ergocalciferol (Vitamin D2) and cholecalciferol are the two types of vitamin D that are available (Vitamin D3). Ergocalciferol is produced by plants, whereas cholecalciferol is produced by animals.

Vitamin D3 is commonly recommended for people who are at risk of vitamin D deficiency, which can result in weak bones and osteoporosis in adults.

Several studies, however, suggest that Vitamin D increases calcium absorption to support and promote bone health (2),(3).

Vitamin D3 is better absorbed by your body, and studies show that increasing your intake of Vitamin D3 can help you achieve peak bone density.

Small studies indicate a link between muscle strength and high vitamin D levels. Additionally, Vitamin D has been shown to aid in the management of bone density.

Vitamin K2 (as menaquinone-7), 50 mcg

Vitamin K, like vitamin D, comes in two forms. Vitamin K1 (phylloquinone) and Vitamin K2 (menaquinone) is found in animals and fermented foods (4).

Vitamin K2 is further subdivided into several subtypes, the most important of which are Mk-7 and Mk-4. Mk-7 is more effective than other vitamins K, such as K1, because it is more bioavailable and has a longer half-life.

According to a recent 2020 study on Mk-7, it increases bone mineral density and promotes bone quality and strength.

Vitamin K2 is essential for the metabolism of calcium, the mineral found in your teeth and bones. It also activates the calcium-blinding activities of two proteins, matrix GLA protein and osteocalcin, which aid in bone formation and maintenance (5).

In Japan, vitamin K supplements are also officially recommended for the prevention and treatment of osteoporosis.

Calcium (from algas calcareas), 360 mg

Algas calcareas is a dietary supplement derived from marine algae. Research has shown that algae can help with bone health and changes in total body bone mineral density.

Studies showed that Algas Calcareas has numerous health benefits, including bone health, joint health, pain relief, circulatory system benefits, and increased energy.

Calcium is an important mineral for strong bones, and studies have shown that an adequate intake of calcium, vitamin D, and protein can reduce the risk of bone fractures and osteoporosis.

Magnesium (from algas calcareas and magnesium oxide), 175 mg

Magnesium is a mineral that is essential for many bodily processes, including bone health and protection against bone loss.

Both too much and too little magnesium can be harmful to your bones. According to a review published in 2021, having less of this mineral is linked to a higher risk of osteoporosis, a condition that makes bones brittle and weak.

In a different recent study, it was discovered that increasing magnesium intake increased the bone mineral density in the femoral neck and hip, both of which are susceptible to fracture.

Aside from that, we couldn’t find any studies or research on magnesium oxide that helped to prevent bone loss or promote bone density.

More research on the effectiveness and related to bone health of magnesium from Algas calcareous and Magnesium oxide are required.

Boron (as glycinate), 1.5 mg

Boron is an important trace mineral. Boron may improve your bone health, according to available animal studies. However, one human study has shown that boron can affect bone density.

A 2020 review found that boron supplementation is helpful for supporting bone health and can help prevent and maintain adequate bone mineral density in humans.

A clinical trial discovered no difference in bone mineral density among athletes receiving 3 mg of boron daily.

It has a conflict of interest in improving bone health and density, so more research, clinical trials, and studies are needed to prove its efficacy on bone health.

AlgaeCal Plus Benefits

AlgaeCal Plus, a calcium supplement for bone health, is made entirely of vitamins and minerals. Boron and Magnesium, in addition to Calcium, have been included to ensure maximum efficiency.

Each ingredient contains something beneficial to bone growth and prevention. However, it is unknown how quickly you will see the results.

Some of the benefits of AlgaeCal Plus are as follows:

  • Because it contains vitamin D, it aids in the body’s ability to absorb calcium.
  • This supplement can help with bone loss and bone formation.
  • Can aid in bone strength maintenance.
  • It contains minerals such as calcium, vitamins, and magnesium, which promote overall bone health and increased bone mineral density.

Potential Side Effects Of AlgaeCal Plus

AlgaeCal Plus supplement should be taken twice a day with meals, and AlgaeCal recommends a full dose of 4 capsules per day.

The product specifies on their FAQs page that AlgaeCal plus doesn’t cause side effects such as gas, bloating, and constipation because their formula is derived from plant calcium.

And, unlike regular calcium supplements, which typically contain hard-to-digest rock-source calcium, AlgaeCal Plus contains a variety of balancing minerals, so you won’t experience these gastrointestinal side effects.

Digestive upset and diarrhea may occur as a result of Magnesium oxide. If you try this product without food and experience stomach upset or other digestive issues, definitely try taking it with meals and see if the problem resolves itself.

If you can tolerate AlgaeCal Plus without having severe allergies, there is no problem; however, if you have allergies, it is best to consult with your allergist for the best recommendation.

For example, it contains active ingredients such as magnesium oxide, and vitamin D3 cholecalciferol, which is associated with a serious allergic reaction to these drugs and are uncommon, if they occur, seek immediate medical attention.

Heart attacks, strokes, and calcium buildup in the blood (hypercalcemia), which can result in nausea and vomiting, weakness, and frequent urination, have all been linked to excessive vitamin D and K intake (6).

Otherwise, adverse side effects from this plant-based algae calcium supplement are rare.

They have specified serious drug interactions with this supplement when using/consuming it, and on their official product page read and discuss with your doctor or stop taking this product if you have any interactions mentioned on their website.

Clinical studies for AlgaeCal plus with their product strontium boost have been completed by a third party and are available on their website.

It is best to speak or consult with your primary care provider or doctor before taking or adding any new supplement, such as AlgaeCal Plus, to ensure that this supplement is safe for you.

How does AlgaeCal Plus Support Bone Health?

AlgaeCal Plus has a set of natural minerals and vitamins that are specialized in helping individuals to increase their bone density and stop bone loss.

It has 720mg – 800mg of calcium per serving, which is close to or more than half of your daily calcium requirement (7). 

As a result, tiny calcium crystals from your blood spread throughout the collagen framework. The hard crystals fill in all the crevices. Calcium and collagen work together to strengthen and stretch bones (8).

AlgaeCal Plus contains vitamin C as an active ingredient, which aids in the recovery from menopause and the treatment of people with compromised bone structure. It is also effective in the treatment of osteoporosis.

Both vitamin D and vitamin K, which are present in AlageCal Plus, aid in the prevention of conditions such as bone loss or osteoporosis and are thus essential for your overall bone health.

Vitamin K also stimulates calcium-binding activities, which aid in bone formation and maintenance.

Magnesium deficiency contributes to osteoporosis both directly and indirectly by influencing the secretion and activity of the parathyroid hormone and by promoting low-grade inflammation.

AlgaeCal Plus: Cost And Where To Buy

The bone health supplement Algaecal is present for purchase at two main locations i.e. their official website and Amazon. 

However, there’s some price difference at both places which you must take into consideration. On the official website, the one-month supply comes for $79 for a bottle. 

You receive a discount when you take more than one-month supply at a time. Same time, on Amazon one bottle of Algaecal Plus, comes for $69. 

But we think the official website is the best buy place since they provide you with a one-year money-back guarantee, which makes a few extra dollars worth paying.

On their official stores, the reviews section is filled with only positive reviews that you can read, but we don’t include those reviews because they are frequently manipulated by the brand/company itself.

Below are some of the AlgaeCal Plus positive and negative reviews from Amazon:

Eleonore kidder says – It works. I went from osteoporosis to osteopenia

“I like that it works. The capsules are fairly easy to swallow. And most importantly I no longer am in osteoporosis. Thanks”

Miriam Kook says – This product helped me to go from Osteoporosis to Osteopenia in one year!

“I have been taking Algaecal Plus and Strontium Boost, both AlgaeCal products for almost three years. In my first year, my bone density test results showed that I improved in all three categories so much that I went from Osteoporosis to Osteopenia.”


“I ignored the reviews on this, but I have very, very bad diarrhea from this just like the rest. Do yourself a BIG favor DO NOT BUY this, it’s not worth it.”

Christine Crescenzi says – Upset stomach and felt like vomiting

“Got an immediate upset stomach and felt like vomiting after taking with food as instructed. Lasted a couple of hours. After the second dose had an immediate upset stomach and felt like vomiting again. I was so hoping this would be an alternative to building bone density. Unfortunately, this is not a supplement without side effects. I would like my money back”

Is AlgaeCal Plus Worth Buying?

AlgaeCal Plus is a calcium-based supplement that is designed to increase your bone formation, and bone density, prevent bone loss, and relieve joint pain.

Having a high satisfaction rate from users, AlgaeCal stands out from most other bone health or calcium supplements in terms of effectiveness. 

The price of the supplement is definitely expensive. However, for the price you pay, you get benefits worth paying for. Keep in mind, that you need to use AlgaeCal Plus for a really long in order to maintain results. 

Most people reported to experienced relief from Osteoporosis and calcium deficiency when they used AlgaeCal Plus. Few even found themselves to have an increase in Vitamin D levels.

So AlgaeCal Plus could be worth buying if you are someone having lower bone density, joint pain, suffering from osteoporosis, and aren’t able to get enough calcium through your diet. 

This is even helpful for women in their menopause. The dose of the capsule is 4 each day which is a little headache since most typical supplements are needed to be taken twice.
