According to the International Osteoporosis Foundation, one in three women over 50 will experience an osteoporotic fracture. Many seek natural ways to combat bone loss, and AlgaeCal Plus is often highlighted as a potential solution, but the question remains: does AlgaeCal Plus really work? We examine the scientific evidence and key components to find out.

Quick Summary

An in-depth look at AlgaeCal Plus's effectiveness, analyzing its plant-based calcium source, vitamin and mineral blend, and supporting clinical studies. A review of its claims, potential side effects, and how it compares to traditional calcium supplements.

Key Points

Proven to increase BMD: Clinical studies show users of AlgaeCal Plus (especially with Strontium Boost) consistently achieve measurable increases in bone density, unlike traditional calcium which mostly just slows bone loss.
Multi-nutrient formula: Beyond calcium and vitamin D, AlgaeCal Plus contains 14 other bone-supporting minerals and vitamins, including K2 (MK-7) and magnesium, which work together for better bone formation and absorption.
Plant-based for better absorption: Derived from marine algae, AlgaeCal's mineral structure is more bioavailable and easier to digest than rock-based calcium carbonate, leading to fewer gastrointestinal issues.
Long-term results confirmed: A 7-year study demonstrated sustained and linear bone density increases in users, with no adverse side effects reported in extensive blood panel testing.
Safety profile and precautions: AlgaeCal is considered safe, though it's important to consult a doctor due to potential interactions with medications like blood thinners (due to Vitamin K2) and to monitor health conditions.
Consider the cost: AlgaeCal Plus and the optional Strontium Boost are more expensive than basic calcium supplements, a factor many users must weigh against the potential for reversing bone loss.

Understanding AlgaeCal Plus: More Than Just Calcium

AlgaeCal Plus is a plant-based bone health supplement derived from marine algae. Unlike conventional calcium supplements sourced from rock materials, AlgaeCal provides calcium along with 15 other bone-supporting minerals and vitamins. The supplement's approach is that this multi-nutrient blend is more effective for building bone density than taking calcium and vitamin D alone.

The Multi-Nutrient Approach to Bone Health

Bone health requires various nutrients beyond just calcium. AlgaeCal Plus contains several ingredients intended to support bone formation. These include Calcium and Magnesium in a 2:1 ratio, Vitamin D3 for calcium absorption, Vitamin K2 (as MK-7) to direct calcium to bones, Boron which aids vitamin D metabolism and mineral retention, and other trace minerals like strontium, manganese, copper, and zinc naturally present in the algae.

Scientific Evidence: Can AlgaeCal Plus Increase Bone Density?

AlgaeCal highlights clinical studies to support its claims of increasing bone density. A 7-year study published in the Journal of the American College of Nutrition found that women taking AlgaeCal Plus and Strontium Boost had an average annual increase of 1.04% in bone mineral density (BMD). Earlier studies also showed significant BMD increases over shorter periods, particularly with Strontium Boost. A lab study comparing AlgaeCal to rock-based calcium sources found AlgaeCal was more effective in promoting the growth of bone-building cells.

AlgaeCal vs. Traditional Calcium Supplements: A Comparison


Feature	AlgaeCal Plus	Traditional Calcium Carbonate/Citrate
Source	Plant-based marine algae	Rock-based
Composition	Multi-nutrient formula	Isolated calcium mineral
Absorption	Higher bioavailability	Less readily absorbed
Bone Building	Shown to increase bone mineral density	Typically slows bone density loss
Side Effects	Fewer digestive issues reported	May cause digestive issues or contribute to arterial calcification

Customer Experiences and Considerations

Many users report positive results with AlgaeCal Plus, including increased bone density on DEXA scans. The plant-based nature is often appreciated for causing fewer digestive side effects compared to rock-sourced options. However, AlgaeCal Plus is more expensive than standard calcium supplements. Individual results can vary.

What About Combining with Strontium Boost?

Combining AlgaeCal Plus with Strontium Boost is recommended for those with bone loss. Strontium can help inhibit bone breakdown and stimulate new bone growth. Studies show this combination leads to more significant BMD increases.

Potential Interactions and Precautions

AlgaeCal Plus contains Vitamin K2, which can interact with blood thinners like Warfarin. Strontium Boost should not be taken by pregnant or nursing women, and its effect on blood tests should be discussed with a doctor. Those with kidney issues or hyperparathyroidism should consult a healthcare provider before use.

Conclusion

Based on clinical studies and customer feedback, AlgaeCal Plus appears to be effective for increasing bone mineral density, particularly when used with Strontium Boost. Its plant-based, multi-nutrient formula offers advantages over traditional calcium supplements, which primarily slow bone loss. While more costly than standard calcium, the potential for rebuilding bone may be a worthwhile investment. Always consult a healthcare provider before starting any new supplement, especially if you have health conditions or take other medications.

Research the ingredients: Understanding the function of AlgaeCal Plus's components, including plant-based calcium, vitamins K2 and D3, is important for bone health. Examine clinical evidence: Several peer-reviewed studies support AlgaeCal Plus's efficacy and its ability to increase bone mineral density (BMD). Consider the Strontium Boost combo: For those with diagnosed bone loss, combining AlgaeCal Plus with Strontium Boost has shown greater increases in BMD in clinical trials. Weigh the side effects: AlgaeCal's plant-based formula is generally well-tolerated with fewer reported digestive issues than some traditional calcium supplements. Consult a doctor: Discussing AlgaeCal Plus with a healthcare professional is crucial, especially if you have existing health conditions or take medications.

Frequently Asked Questions

Measurable improvements in bone density with AlgaeCal Plus, especially when taken with Strontium Boost, can be seen in as little as six months, according to clinical studies.

Many users report fewer gastrointestinal side effects like constipation or gas compared to rock-based calcium supplements. However, some individuals may still experience mild digestive issues or headaches, and those on blood thinners should consult a doctor due to the Vitamin K2 content.

Clinical studies suggest AlgaeCal Plus is more effective, as it has been shown to increase bone density, while traditional calcium supplements typically only help to slow the rate of bone loss.

AlgaeCal Plus is recommended for postmenopausal women, older adults, individuals with lactose intolerance, or anyone looking for a natural, plant-based supplement to improve their bone health and density.

The Bone Builder Pack combines AlgaeCal Plus with Strontium Boost. This combination is clinically proven to increase bone density faster and is recommended for those with existing bone loss.

Yes, AlgaeCal Plus should be taken with meals. This increases stomach acid production, which helps dissolve the minerals for better absorption in the intestinal tract.

Yes, AlgaeCal is derived from plant-based marine algae and is free of dairy, soy, and gluten, making it a suitable option for vegans.
