Natural Factors Stress-Relax Melatonin 3 mg
Brand: Natural Factors · Form: TABLET [E0155]
Our assessment
The evidence shows that this product contains 3 mg of melatonin, a dose commonly used for sleep support. However, the data provided does not include any specific studies or health claims about melatonin itself. For the ingredient calcium, which is listed in the NIH ODS data, the evidence supports its role in bone mineralization and neuromuscular relaxation [NIH ODS]. We cannot assess the specific benefits of this melatonin product based on the data provided.
How it works
Regarding the calcium component, think of it as a structural builder — it supports bone density and mineral deposition, and also helps your muscles relax and nerves signal properly [NIH ODS]. For the melatonin in this product, specific mechanism details are not available in the provided data.
Safety profile
Data not available for the specific adverse event reports tied to this product. The FDA total adverse event reports across all supplements is 592,059, but this number is not specific to this product. For calcium, high intakes may increase the risk of heart disease and prostate cancer, and can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by consulting your healthcare provider before taking this melatonin supplement, especially if you take any medications that interact with calcium as listed above. The data does not provide a specific recommended dose or safety profile for the 3 mg melatonin content itself. Your best course is to seek guidance from your doctor or pharmacist to ensure this product is appropriate for your individual health needs [NIH ODS].
