Calcium's role in bone pain unclear
In-depth clinical characterization of intravenous iron infusion-induced hypophosphatemic osteomalacia and its resolution.
Calcium's effect isn't isolated
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
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
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.
