Our assessment
The evidence shows that calcium is a critical mineral for your bone health, but it requires careful attention to dosing and timing. Our assessment is that you should aim to meet your calcium needs primarily through food, not supplements, to avoid the potential risks associated with high intakes [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It supports bone density and mineral deposition, which is essential for maintaining strong bones as you age. It also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly after activity [NIH ODS].
Safety profile
Data not available on adverse events specifically for Nature's Way Alive! Vitamin C. The overall FDA database includes 592,059 total adverse event reports for all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Side effects from excessively high levels in the blood and urine include 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] [FDA data].
Our recommendation
We recommend getting your calcium from food sources first. If you choose a supplement, be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. Take calcium at a separate time from these medications [NIH ODS]. Do not exceed the recommended daily intake without consulting your doctor.
