Our assessment
The evidence shows that you should be cautious with this product. The data provided is for calcium, not melatonin. For the specific ingredient listed on the label, “Data not available.” The overall FDA adverse event database contains 592059 reports across all supplements, but specific side effect counts for melatonin are not provided in this data set [FDA data].
How it works
Think of calcium as a structural and signaling mineral — it supports bone mineralization and density, and it also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS]. However, this mechanism applies to calcium, and the product in question is melatonin. For melatonin’s mechanism, “Data not available” from the provided information.
Safety profile
High levels of calcium 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]. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. For melatonin-specific side effects, “Data not available.”
Our recommendation
Because the provided data set covers calcium rather than melatonin, we cannot offer a specific recommendation for this product. You should consult the product label for ingredient-specific warnings and speak with your healthcare provider before starting any new supplement. For melatonin’s safety and dosing, “Data not available” from this data set.
