Our assessment
The evidence shows that calcium is a critical mineral for bone health, but the data on supplementation is nuanced. For most adults, getting calcium from food is preferred, and high-dose supplements carry specific risks that you need to understand [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton and a signaling molecule for your nerves and muscles. It supports bone density through mineralization and helps your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Very high blood and urine levels of calcium can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for this specific product's dosage. Aim to meet your calcium needs through diet first. If you take a supplement, do not exceed the tolerable upper intake level without medical supervision. Be aware of the medication interactions listed above, and take calcium separately from those drugs [NIH ODS].
