It really worked when combined with exercise. After being diagnosed with osteoporosis in my lumbar spine at 57, I tried this calcium supplement. For two years, I took three capsules daily and combined this with strength and aerobic exercise. I recently had my DEXA scan, and my T-score improved from -2.7 to -1.5! I was amazed by the results! I plan to keep up the effort to hopefully reverse even the osteopenia over the next few years.

I will always take this product. I had osteoporosis, and after starting it, my condition began to improve within months. After two years, my bone density tests were normal. When I tried to stop and switched to regular calcium, I developed osteopenia, so I resumed this and returned to the normal range. No other calcium compares to this one.
Our research explored the effects of a new calcium-loaded complex, made from Antarctic krill protein and enriched with pectin, on calcium absorption and bone health in mice with calcium deficiency. We created a model that simulated calcium deficiency, which is a significant concern as it can contribute to osteoporosis.
We observed that chronic calcium deprivation led to decreased calcium absorption and deterioration of bone structure. However, the P + Ca + HMP complex significantly improved calcium retention and increased the strength of the femur, indicating a positive impact on bone health.
Additionally, this complex improved the structure of the trabecular network, which is essential for maintaining strong bones. The presence of beneficial bacteria in the gut also rose after the intervention, and these were linked to better calcium absorption and bone synthesis. Overall, these findings point to the potential of the P + Ca + HMP complex as an effective calcium supplement that could help prevent calcium deficiency and thus support bone health.

Combination therapy for osteoporosis
Effect of salmon calcitonin combined with calcium antagonist on blood calcium and phosphorus ion concentration in osteoporosis rats.
We explored how salmon calcitonin (sCT) works in tandem with calcium antagonists—specifically verapamil, nifedipine, and diltiazem—to influence blood calcium and phosphorus levels in female rats with osteoporosis post-ovarian removal.
The study involved a systematic approach where we administered these combinations to different groups of osteoporotic rats and measured their blood levels. Our findings revealed that combining sCT with nifedipine had a particularly strong effect in lowering both calcium and phosphorus in the blood, outperforming the use of sCT alone.
Our analysis indicated that while sCT with nifedipine was most effective, the combinations with verapamil and diltiazem also showed beneficial effects, albeit to a lesser extent. These insights provide valuable information on how combination therapies might be targeted for treating postmenopausal osteoporosis, potentially paving the way for more effective treatment options in human patients.

Probiotic support for osteoporosis treatment
increases serum vitamin D metabolite levels and modulates intestinal flora to alleviate osteoporosis in mice.
We explored how a specific probiotic strain, FSHHK13M1, affects vitamin D metabolism and osteoporosis in mice. Previous research pointed out that the gut microbiota plays a crucial role in vitamin D metabolism, which is especially relevant for older adults who tend to suffer from osteoporosis due to declining organ functions.
Our study demonstrated that treating the mice with FSHHK13M1 led to a significant increase in their serum levels of active vitamin D metabolites, particularly 1,25-dihydroxy vitamin D. This increase was linked to activation of important bone health pathways, helping to fortify bone structure and function.
Not only did we observe improvements in vitamin D levels, but the intervention also restored balance in the gut microbiota, which showed signs of imbalance in mice suffering from osteoporosis. The findings suggest that FSHHK13M1 could be a promising direction for improving bone health and reducing fracture risks in the elderly by enhancing vitamin D levels naturally.
Overall, this research highlights the potential of combining probiotics with vitamin D strategies for better management of osteoporosis, especially in older populations who often face challenges absorbing conventional treatments.

Bone mass rebuilt
11 people found this helpful
I highly recommend this product. After taking Garden of Life Vitamin Code RAW Calcium for some time, my results support its effectiveness. I moved from a -4 osteoporosis to building over 10% bone mass. While maintaining a balanced diet and cutting sugar, my age and health issues affected my bones. When I received my first report, I did my research and ordered this product along with Strontium Bone Maker, and now I no longer have osteoporosis.
Osteoporosis is a medical condition characterized by weakened bones, making them fragile and more prone to fractures. This condition occurs when the body loses too much bone mass, doesn't make enough bone, or a combination of both. As bones lose density, they can break more easily, often as a result of minor falls or injury. Osteoporosis is often referred to as a "silent disease" because bone loss occurs without any symptoms until a fracture occurs, often in the hip, spine, or wrist.
Risk factors for developing osteoporosis include age, gender (it’s more common in women), family history, low body weight, and certain medical conditions and medications. Lifestyle choices such as smoking, excessive alcohol consumption, and a diet low in calcium and vitamin D can also contribute to bone loss. Regular weight-bearing exercise, ensuring adequate nutrition, and, in some cases, medications can help prevent or manage osteoporosis. If you believe you may be at risk, it is important to consult with a healthcare professional for appropriate screening and intervention options.
Calcium is a chemical element represented by the symbol Ca and atomic number 20. It is an essential mineral in the body, playing a critical role in various physiological processes. As one of the most abundant elements in nature, calcium is particularly vital for maintaining strong bones and teeth, where about 99% of the body's calcium is stored. Beyond its structural function, calcium is crucial in muscle contraction, blood clotting, and nerve transmission, making it a key player in overall health.
Dietary sources of calcium include dairy products such as milk, yogurt, and cheese, as well as leafy green vegetables, nuts, seeds, and fortified foods. The recommended daily intake of calcium varies by age and sex, but generally, adults should aim for approximately 1,000 mg per day. For those who may struggle to meet their needs through diet alone, calcium supplements are available but should be taken with caution. It's essential to consult with a healthcare provider before starting any supplement regimen to avoid potential side effects or interactions with medications.
Calcium plays a crucial role in maintaining bone health and is often recommended as a key nutrient for individuals at risk of osteoporosis, a condition characterized by weak and brittle bones. Adequate calcium intake helps to support bone density, making bones stronger and less susceptible to fractures. For adults, the recommended daily intake of calcium is around 1,000 to 1,200 mg, depending on age and gender. Including calcium-rich foods like dairy products, leafy greens, and fortified foods can significantly contribute to achieving this daily requirement.
However, it's important to note that calcium alone may not be sufficient to prevent or treat osteoporosis. A holistic approach that includes vitamin D for calcium absorption, regular weight-bearing exercise, and lifestyle modifications is essential for maintaining bone health. Additionally, individuals should consult with healthcare professionals to assess their specific needs and explore comprehensive osteoporosis management strategies. In sum, while calcium is vital for bone health, it should be part of a broader plan to combat osteoporosis effectively.
Based on user reviews, the timeline for seeing results from taking calcium supplements for osteoporosis can vary. Many users report noticeable improvements within a few months to a year. For instance, one user stated that their condition began to improve within months of starting the supplement, and after two years, their bone density tests returned to normal (Read Review). Another reviewer mentioned significant improvements in bone density within six months of usage (Read Review).
Longer-term users have also shared positive experiences, highlighting that after a year and a half, their bone density measurements exceeded expected values for their age, showing clear signs of improvement (Read Review). Overall, while individual results can differ, many users seem to begin experiencing beneficial effects within a few months of consistent use of these supplements.
The science behind calcium supplementation for osteoporosis is somewhat mixed. A review focused on calcium's impact as a treatment within combinations revealed that while it is commonly used alongside medications, isolating its specific effects on osteoporosis remains unclear (see [1]). Although other studies showed potential benefits of calcium-related compounds, such as a calcium complex derived from krill protein that significantly improved bone structure and retention in calcium-deficient mice, this was still in animal models (see [2]).
In human studies, the relationship between calcium and vitamin D supplementation and potential complications like kidney stones was highlighted, emphasizing the need for careful monitoring during treatment (see [5]). Additionally, vitamin D’s importance in managing bone density highlights its interaction with calcium, indicating that while they are essential for bone health, how they specifically work in the context of osteoporosis treatment requires more focused research (see [12]). Therefore, while there is some support for calcium supplementation, particularly in combination with other treatments, the evidence remains inconclusive when considered in isolation, warranting further investigation to solidify its role in osteoporosis management.
Users have reported a range of improvements in their osteoporosis symptoms after taking the Garden of Life calcium supplement, with many expressing significant satisfaction with their results. For instance, one reviewer highlighted a substantial improvement in their bone density tests, returning to normal after two years of use (Read Review). Another user noted a 14% improvement in bone density after three years, which they attributed to the natural ingredients in the supplement (Read Review). Additionally, many users shared that they experienced positive changes in their overall bone health, such as improved bone density scans and reductions in pain, which helped them avoid more aggressive treatments or medications overall (Read Review).
Furthermore, users often remarked on the supplement's natural formulation, which includes beneficial vitamins and minerals that aid in calcium absorption and overall vitality. Reports have varied, with some users noticing changes in as little as a week, including stronger nails and diminished discomfort, while others saw more progressive improvements over several months (Read Review, Read Review). Overall, while individual results can vary, these anecdotal experiences reflect a trend of positive outcomes for individuals managing osteoporosis with this supplement.
Users have reported positive experiences when combining Garden of Life calcium supplements with other supplements and treatments for managing osteoporosis. For instance, one user mentioned using this supplement alongside Prolia injections, noting that it helped maintain good calcium levels and contributed to their recovery from osteoporosis to osteopenia (Read Review). Additionally, a reviewer who integrated vitamin D3 and K2 into their routine along with the calcium supplement reported significant improvements in bone density, allowing them to avoid medication altogether (Read Review).
Another user also highlighted the importance of taking vitamin K2 with their calcium regimen, as it directs calcium into the bones effectively, enhancing the overall bone health benefits of the supplement (Read Review). These accounts suggest that combining Garden of Life's calcium with other supportive nutrients can lead to more significant improvements in bone density and overall osteoporosis management, reflecting a trend among users who are seeking holistic approaches to strengthen their bones.
Users report a positive experience with specific calcium supplements, particularly Garden of Life products, in treating osteoporosis. Many reviews suggest that the right dosage varies, with several users mentioning taking multiple tablets a day. For instance, one user indicated they take four tablets daily alongside vitamin D3 and K2, reporting notable improvements in bone density over time Read Review. Others also shared experiences of using these supplements consistently, appreciating their organic ingredients and high bioavailability Read Review.
Additionally, the importance of maintaining consistent use of these supplements was highlighted, with some users noting that switching to regular calcium products resulted in setbacks in their condition Read Review. A few reviews mentioned the combination of nutrients, like vitamin K2, as crucial for directing calcium into bones and maximizing effectiveness Read Review. Overall, users emphasize that finding the right dose may involve some trial and adjustment based on individual responses and combined nutrient intake.

Calcium's role in osteoporosis unclear
Optimizing bone health in people living with HIV: insights from a network meta-analysis of randomized controlled trials.
We conducted a thorough review of various treatments for osteoporosis in people living with HIV, particularly focusing on the role of calcium. Our analysis included randomized controlled trials that compared different treatment strategies, such as calcium combined with medications like zoledronate or alendronate.
While zoledronate showed promising results in improving bone mineral density, calcium was often used alongside these treatments. Unfortunately, this combination makes it difficult to isolate the specific effects of calcium on osteoporosis. We found that alendronate, although it helped reduce certain bone turnover markers, did not significantly improve bone density.
Overall, the study indicates that while calcium plays a role in treatment combinations, its isolated impact on osteoporosis remains unclear. We emphasized the need for more focused research to determine calcium's true effectiveness in enhancing bone health for those affected by HIV.

Calcium's risks for kidney stones
Association between calcium and vitamin D supplementation and increased risk of kidney stone formation in patients with osteoporosis in Southwest China: a cross-sectional study.
We explored the effects of calcium and vitamin D supplementation on osteoporosis, particularly focusing on the risk of kidney stones. In our study, 204 older adults in southwest China took daily doses of calcium and vitamin D for at least a year. We used various statistical analyses to understand the relationship between these supplements and kidney stone formation.
Our findings reveal that there is a potential link between the use of calcium supplements for osteoporosis and an increased risk of developing kidney stones. It seems that a history of kidney stones can elevate the likelihood of experiencing them again while undergoing such supplementation, likely due to higher urinary calcium levels.
While calcium is essential for bone health, our results suggest that patients need to be cautious. This research highlights the importance of monitoring kidney health while receiving calcium and vitamin D treatment to prevent complications like kidney stones.

Vitamin D's impact on osteoporosis
The Vitamin D-Sirt1/PGC1α Axis Regulates Bone Metabolism and Counteracts Osteoporosis.
We aimed to understand how vitamin D influences bone health and helps combat osteoporosis, a condition that weakens bones. In our study, we used various mouse models, including those that mimic a deficiency in active vitamin D. Through a range of advanced methods, we assessed how changes in vitamin D levels affected bone structure and metabolism.
The research revealed that insufficient vitamin D led to a drop in Sirt1, a gene that plays a crucial role in maintaining bone density. This lack of Sirt1 resulted in increased bone loss. However, when we boosted Sirt1 levels in bone stem cells, we observed a reversal in bone loss. This improvement happened because higher Sirt1 levels reduced oxidative stress, slowed down aging processes in bone cells, and enhanced new bone formation while curbing bone resorption.
Additionally, our findings indicated that vitamin D directly stimulates Sirt1 expression in these stem cells, which is vital for bone health. We also explored the effects of resveratrol, a natural compound known for activating Sirt1, and found it helped alleviate osteoporosis symptoms linked to vitamin D deficiency by enhancing the relationship between Sirt1 and another protein called PGC1α, which supports bone formation and energy metabolism.
This research underscores the importance of the vitamin D-Sirt1/PGC1α axis in bone metabolism, providing insight into how vitamin D can serve as a target for osteoporosis prevention and treatment.
