Overview
Bone loss is a gradual yet serious concern that often goes unnoticed until a fracture or diagnosis makes it real. As we age, maintaining strong, resilient bones becomes more challenging, especially with traditional calcium supplements that merely slow down the process rather than reverse it.
This leaves many individuals searching for a more effective approach to restore bone strength and density naturally.
Introducing AlgaeCal Plus, a clinically supported supplement formulated with plant-based calcium and 15 other bone-essential nutrients that work together to not only stop bone loss but also help rebuild it.
But can AlgaeCal Plus truly deliver measurable improvements in bone density? Read on as we explore its ingredients, benefits, clinical research, and customer experiences in this detailed AlgaeCal Plus review.

What Is Algaecal Plus?

How Does Algaecal Plus Work?
AlgaeCal Plus works by supplying your body with a full spectrum of 16 bone-essential nutrients derived from sustainably sourced marine algae.
Unlike traditional rock-based calcium, which only slows bone loss, AlgaeCal’s plant-based formula promotes bone regeneration by providing highly bioavailable calcium, magnesium, and trace minerals, along with vitamins D3, K2-7, and C.
These ingredients work synergistically to support bone remodeling and enhance calcium absorption into the bone matrix rather than arteries or kidneys.
Algaecal Plus Ingredients
There are several key vitamins and minerals in this supplement. Here are some of the primary active ingredients:
AlgaeCal® (Mesophyllum Superpositum) – This marine algae is a natural, plant-based calcium source that contains all 13 essential bone-supporting minerals. It’s easily absorbed by the body, unlike traditional rock-based calcium supplements.
A study published in the Journal of the American Nutraceutical Association showed AlgaeCal increased bone mineral density in women over 40 without side effects.[1]
Calcium (720 mg from AlgaeCal) – Calcium is essential for building and maintaining strong bones. It also supports heart health, muscle contractions, nerve transmission, and more. Sourced from algae, this calcium is gentle on the stomach and highly bioavailable.
Magnesium (350 mg) – Magnesium complements calcium by supporting bone structure and helping regulate calcium metabolism. It also plays a role in over 300 enzyme reactions in the body, including energy production and nerve function.
A study in Nutrients showed that magnesium intake is positively associated with bone mineral density in adults.[2]
Vitamin K2 (100 mcg, MK-7) – This is a key nutrient in the human body, and according to the National Institutes of Health, it’s essential for healthy bone functioning. It plays other roles in the body as well, such as helping with blood clotting.[3]
Vitamin D3 – This is a fat-soluble vitamin whose most important job is to elevate your body’s absorption of calcium, keeping the bones healthy. According to Harvard Health Publishing, a lack of vitamin D can create rickets in children and osteoporosis in adults.[4]
Boron – This is a mineral which is largely derived from food. According to Integrative Medicine, it’s crucial for growing and maintaining the bones. It has numerous other functions, like raising the levels of antioxidants in the body which strengthens immunity.[5]
Vitamin C (50 mg) – Vitamin C is crucial for collagen production, which forms the framework of bones. It also supports immunity and acts as a powerful antioxidant.
Strontium (Trace amount) – Strontium supports bone health by both stimulating bone formation and slowing bone breakdown—a rare dual action among minerals.
Benefits of AlgaeCal Plus
Increases Bone Density: Unlike traditional calcium supplements, AlgaeCal Plus is clinically proven to increase bone density, even in older adults.
Improves Bone Strength and Flexibility: With 16 essential bone-supporting nutrients, it enhances not just bone density but also bone quality and resilience.
Reduces Osteopenia and Osteoporosis Risk: Regular use may help reverse osteopenia and lower the risk of fractures caused by weakened bones.
Boosts Calcium Absorption: Vitamin D3 and K2-7 ensure that calcium is absorbed effectively and directed to the bones—not soft tissues like arteries.
AlgaeCal Plus Side Effects
Mild Digestive Issues: Some users report occasional bloating, gas, or stomach discomfort—typically when taken without food or at higher doses.
Constipation in Sensitive Individuals: Although less common than with rock-based calcium, a few people may still experience constipation, especially if their water intake is low.
Iodine Sensitivity: As AlgaeCal is derived from marine algae, it contains natural iodine. Individuals with thyroid issues or iodine sensitivity should consult their healthcare provider.
Interactions with Medications: AlgaeCal Plus may interfere with the absorption of certain medications (e.g., thyroid drugs or antibiotics) if taken too closely together. Spacing doses is recommended.
Is Algaecal Plus Safe?
The safety of AlgaeCal Plus largely depends on an individual’s health condition and tolerance to dietary supplements.
It is made from plant-sourced calcium and includes 16 bone-essential nutrients, which are generally considered safe for most adults. However, some users may experience mild digestive discomfort or interactions with certain medications.
Those with pre-existing conditions, thyroid concerns, or shellfish allergies should consult their healthcare provider before beginning AlgaeCal Plus.
Algaecal Plus Customer Reviews & Results
Not feeling well after taking this supplement
I was diagnose with osteoporosis this year (2020) and was prescribed with 6 monthly injection of Prolia – hence when I saw the add for Algae cal I bought straight away as I don’t want to have this injection. When my order arrived I took 1 tablet straightaway after lunch. I feel the difference on my body with one tablet – I feel lethargic (feeling very very tired). Took another tablet after dinner – and I felt I need to go to bed early and find myself struggling to get out of bed the next morning. I still took them for 3 days and I got worse and worse. I stopped taking them now and my body went back to normal. I sleep and wake up as normal. So I guess this tablet is the culprit. I hope I can get refund when I return them. I bought 3 Algae cal and 3 Stronium. – Zony Marcelo
Helped Some, But Progress Was Slow
I’ve used AlgaeCal Plus for months. My latest scan showed minor improvement. It’s not a miracle, but I appreciate the natural ingredients and plan to continue for now. – Olivier Fortin
Easy on Stomach, Still Evaluating Results
I am very happy with the results from using the probiotic I ordered from Nucific. It helps keep me regular with no side effects & has helped me with my weight loss. – Madeline R.

Final Verdict
AlgaeCal Plus is marketed as a plant-based alternative to traditional calcium supplements, featuring a blend of nutrients intended to support bone health. While some clinical studies suggest potential benefits, the results are not universally experienced.
The product requires a commitment to consistent daily use, which may not be ideal for everyone, especially given the need to take four capsules per day. Additionally, the higher price point and potential for mild digestive side effects could be limiting factors.
Not all users report noticeable improvements, and some express concern over the time it takes to see results. As with many supplements, individual outcomes can vary, and it may not be suitable for those with allergies or pre-existing health conditions.
