Allergy Research Group Melatonin 3 mg

Our assessment

The evidence shows that melatonin is a popular supplement for sleep support, but the specific product "Allergy Research Group Melatonin 3 mg" has limited available data. The primary ingredient, melatonin, is not covered in the provided NIH ODS data. However, calcium is listed as an ingredient in the data, and we must rely on that information. Our assessment: you should be cautious, as the data provided does not include detailed efficacy or safety information for melatonin itself.

How it works

Based on the data provided, the ingredient calcium works through bone mineralization to support bone density and through neuromuscular relaxation to support muscle relaxation and nerve signaling [NIH ODS]. No mechanism of action data is available for melatonin in this dataset.

Safety profile

FDA received a total of 592,059 adverse event reports for all products in this database. For the ingredient calcium specifically, safety concerns include that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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]. Data not available for melatonin-specific side effects with report counts.

Our recommendation

Data not available to provide a confident recommendation for Allergy Research Group Melatonin 3 mg. For the calcium component, the data shows it can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Consult your healthcare provider before starting this supplement, as the available data is insufficient to guide safe use.
