NOW Melatonin 3 mg
Brand: NOW · Form: LOZENGE [E0174]
Our assessment
The evidence shows that NOW Melatonin 3 mg is a commonly used supplement, but we must be clear: the data provided here is for calcium, not melatonin. Based on the data available, we cannot assess melatonin specifically. For calcium, our assessment is that it is a critical mineral for bone health, but you must be cautious with dosing [NIH ODS].
How it works
Think of calcium as a structural supporter for your skeleton. It works through bone mineralization, helping to maintain bone density and mineral deposition, and also supports neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
Data not available for melatonin. For calcium, the FDA has received a total of 592059 adverse event reports across all supplements. Specific side effects from high calcium intake include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, and abnormal heart rhythms [FDA data]. High calcium intakes might also increase the risk of heart disease and prostate cancer [NIH ODS].
Our recommendation
For calcium, start with food sources first. If you use supplements, be aware that calcium can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. For melatonin, data not available — consult your healthcare provider for personalized advice.
