Our assessment

Our assessment: The evidence for melatonin is clear, but you need to understand the full picture before taking this supplement. The FDA has received a substantial number of adverse event reports — 592,059 total reports across all supplements — which underscores the importance of using these products carefully. For specific safety data on melatonin itself, data is not available in the provided information. For calcium, which is not the primary ingredient here, the data shows that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS].

How it works

The primary ingredient you are considering is melatonin. While detailed mechanism data is not provided in this specific data set, we can look at how related minerals work for context. For example, calcium supports bone mineralization and neuromuscular relaxation, helping your muscles relax and nerves signal properly [NIH ODS]. Think of it as a support system for your body's structural and signaling functions.

Safety profile

Safety data for melatonin specifically is not available in the provided information. However, for calcium, 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 [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Our recommendation: Because specific safety and efficacy data for this exact product (NutraBio Melatonin 3 mg) is not provided in the data you shared, we cannot make a confident recommendation. You should consult your healthcare provider before starting any new supplement, especially since the FDA has tracked 592,059 total adverse event reports across all supplements [FDA data]. For calcium interactions, be aware that taking calcium with certain medications can reduce their effectiveness [NIH ODS].
