Nature's Way Calcium Complex
Brand: Nature's Way · Form: CAPSULE [E0159]
Our assessment
The evidence shows that calcium is a critical mineral for your bone health and nerve function. For a general audience, the data supports its role, but we must be careful with dosing. Our assessment is that you should only take this supplement if you cannot meet your calcium needs through diet, as high intakes carry real risks [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton and a signal messenger for your nerves. It supports bone mineralization and density, and it helps your muscles relax and your nerves transmit signals properly [NIH ODS]. Without enough calcium, your body will pull it from your bones, which can weaken them over time.
Safety profile
FDA received 592,059 total adverse event reports for all supplements, but specific report counts for this product are not available. The safety data shows that high calcium intakes might increase the risk of heart disease and prostate cancer. High levels in your blood or urine 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]. Also, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by assessing your dietary intake. Most adults need 1,000 to 1,200 mg of calcium daily from all sources. Do not exceed the tolerable upper intake level without medical supervision. If you take this supplement, take it separately from your thyroid medication or antibiotics by at least two hours. Your best bet is to get calcium from food first, and only use a supplement to fill a verified gap [NIH ODS].
