Natural Factors Stress-Relax Melatonin 3 mg Chewable
Brand: Natural Factors · Form: TABLET [E0155]
Our assessment
The evidence shows that this product contains 3 mg of melatonin per chewable tablet. Data on the specific ingredient calcium is available, but there is no specific data on melatonin in the provided information. Our assessment is limited to what is in the data: calcium is a mineral important for bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as a key structural component for your bones and a regulator for your nerves and muscles. It supports bone density and mineral deposition, and it helps with muscle relaxation and nerve signaling [NIH ODS].
Safety profile
Data not available for melatonin specifically. For calcium, high intakes might increase the risk of heart disease and prostate cancer. 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]. The FDA received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product or melatonin are not available in the data [FDA data].
Our recommendation
Given that the data does not include specific information on melatonin's effects, dosage, or safety, we cannot make a recommendation for this specific product. If you are considering a melatonin supplement, consult your healthcare provider first. For calcium, be aware that it can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
