Our assessment

The evidence shows that melatonin is generally considered safe for short-term use, but data provided here focuses on calcium, not melatonin. For calcium, our assessment is that it is a critical mineral for bone health, but you must be careful with dosing to avoid risks [NIH ODS].

How it works

Think of calcium as a structural builder for your skeleton. It supports bone mineralization and density, and also plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS]. This means it helps your muscles relax and your nerves communicate properly.

Safety profile

FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, safety data shows that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from excessively high levels 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]. Note: Specific side effect report counts for calcium are not available from the provided FDA data.

Our recommendation

Start by getting calcium from food sources first. If you take a supplement, be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Take calcium supplements at a different time than these medications. Data not available for melatonin-specific dosing or interactions from the provided sources.
