Our assessment
The evidence shows that calcium is a critical mineral for bone health, but the data on supplements like Natrol Melatonin 3 mg is not directly applicable here. For calcium specifically, our assessment is that you need to be careful with dosing. The data confirms that while calcium supports bone mineralization and nerve signaling, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a structural building block — it supports bone density and mineral deposition, and it also supports muscle relaxation and nerve signaling. This makes it essential for your skeletal and neuromuscular systems to function properly [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high 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. Some research also suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS] [FDA data].
Our recommendation
Start by getting your calcium from food sources first. If you need a supplement, take it with food and separate it from other medications by at least 2 hours. Calcium can reduce absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Stay within the recommended dietary allowance and do not exceed 2,000 mg per day from all sources combined.
