Natural Factors Stress-Relax Melatonin 10 mg
Brand: Natural Factors · Form: TABLET [E0155]
Our assessment
The evidence shows that for the specific product Natural Factors Stress-Relax Melatonin 10 mg, we have data on the ingredient calcium, not melatonin. Therefore, our assessment is limited. For the calcium component of this product, the data confirms its role in bone mineralization and neuromuscular relaxation [NIH ODS]. However, we cannot evaluate the primary ingredient, melatonin, as specific data was not provided.
How it works
Think of calcium as a structural foundation and signaling molecule. It supports bone density through mineralization and helps your muscles relax and nerves signal properly [NIH ODS]. This mechanism contributes to the product's intended relaxation effect.
Safety profile
Data not available for melatonin. For calcium, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels in 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]. The FDA received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product are not available [FDA data].
Our recommendation
Given the lack of data on melatonin, we cannot recommend this specific product for its intended stress-relax purpose. If you are considering it for calcium, be aware of the potential risks and interactions with medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. We advise consulting your healthcare provider before use, as the primary ingredient's safety and efficacy data is not available for review.
