Our assessment
Our assessment: For general bone health and muscle function, the evidence supports a daily calcium intake of 1,000 to 1,200 mg from food and supplements combined [NIH ODS]. However, the data shows you must be cautious with dosing, as excessive intake carries real risks. We recommend you aim to get most of your calcium from dietary sources first.
How it works
Think of calcium as a critical building block for your body. It supports bone mineralization by helping deposit minerals into your skeleton, and it enables neuromuscular relaxation, which is essential for your muscles to relax and your nerves to signal properly [NIH ODS]. Without enough calcium, your body will pull it from your bones, weakening them over time.
Safety profile
FDA has received a total of 592,059 adverse event reports for this product category. The most significant risks come from taking too much. High calcium levels in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Some research also suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Be aware that calcium supplements can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: Do not exceed 2,000 mg of total calcium per day from all sources. Start with a dietary assessment before adding a supplement. If you take calcium, take it with food and separate it from the medications listed above by at least 2 hours [NIH ODS]. For most adults, a supplement of 500 to 600 mg daily is enough to fill dietary gaps. Always consult your doctor before starting, especially if you have kidney issues or a history of heart disease.
