We explored the impact of calcium treatment on bone pain in patients who developed osteomalacia, a condition linked to intravenous iron infusions. Our focus was on a group of 13 patients diagnosed with this condition, who experienced low phosphate levels due to excess fibroblast growth factor 23 (iFGF23) after receiving ferric carboxymaltose (FCM) infusions.
After halting the FCM infusions, these patients were given supportive treatment, which included phosphate, calcium, and active Vitamin D supplementation. We observed improvements in biochemical markers, including increased phosphate levels and reduced pain scores. However, it’s important to note that while calcium was part of the treatment regimen, we could not isolate its specific effects on bone pain from the other supportive measures used.
Ultimately, our findings highlight the importance of monitoring phosphate levels in patients receiving FCM, and stopping these infusions effectively addresses phosphate wasting. Although supportive treatment showed improvements in pain and bone density, the direct impact of calcium on bone pain remains unclear given the combination of treatments involved.

Reduced sensitivity
40 people found this helpful
I’ve taken calcium supplements regularly as I avoid dairy. Though I consume green veggies and nuts, I still notice enamel sensitivity. Hydroxyapatite works just as well to strengthen my teeth and reduce sensitivity, which has improved as I’ve noted new enamel growth on defects. It’s crucial to monitor vitamin D levels for calcium absorption. Avoid breathing through your mouth, particularly at night, for better dental health.

Supports bone metabolism
14 people found this helpful
Calcium in the form of hydroxyapatite has a positive effect on bone metabolism. It's contained in this dietary supplement in a ratio of 2:1 with phosphorus, allowing for complete absorption from the gastrointestinal tract. The slow release of calcium prevents peak hypercalcemia, aiding the fixation of calcium in bone and reducing its excretion by the kidneys. This supplement may be recommended by a health professional.

Pain alleviated quickly
3 people found this helpful
I sought calcium with phosphorus as it's absorbed best this way. I used it during pregnancy, and when I stopped, my back started to hurt. Upon resuming after three days, the pain decreased and eventually disappeared.

Increased density
2 people found this helpful
Effective! After taking calcium hydroxyapatite for 2 months, bioimpedancemetry indicated my bone mineral density increased by 1.5% from 2.5% to 4%. According to the doctor, this is a good outcome.

Gained bone density
2 people found this helpful
I'm in my mid-50s and prior to taking this calcium due to osteopenia, I was losing bone density. After two years of taking it twice daily and with exercise, my DEXA scan showed I gained bone density, which is fantastic considering I would normally lose bone. My spine has returned to normal, and while my hips still have some osteopenia, I've gained bone.

Accelerated healing

Helped build my bones! I broke my foot and, due to osteopenia, the bone was slow to heal. After starting this supplement, the bone finally healed a few weeks later. I fell again but did not break any bones. I plan on taking this for life!

Quality supplement

My bone density test has improved, which is fantastic as I had a calcium deficiency. Along with vitamins D3 & K2, it’s doing its job. My nutritionist advised this is the best quality calcium supplement, and I like it because it works and is easy to take.

Improved bone condition

I found this calcium to be very effective, as I had previously taken citrate before switching. My mother has osteoporosis and, along with vitamin D and K2, this complex improved her bone condition markedly on densitometry. I highly recommend it.

Calcium safety
7 people found this helpful
Many fear calcium may cause an excess and stone formation. To avoid this, I consume this specific form in cycles and ensure it reaches my bones with vitamins K2 and D. I take it yearly, and I’m pleased with the results, especially for my bone health after a hip fracture.

Bone pain resolved

I purchased it for my child whose bones ached due to rapid growth. The doctor recommended calcium hydroxyapatite from American sites. Bone pain issues resolved swiftly. Now, it's prescribed periodically for prevention.
