Sundown Naturals Melatonin 10 mg
Brand: Sundown Naturals · Form: CAPSULE [E0159]
Our assessment
The evidence shows that this product contains 10 mg of melatonin, which is a high dose. Data on this specific brand is limited, and we must rely on general safety information for the active ingredient. For calcium, which is listed in the data, the National Institutes of Health Office of Dietary Supplements notes that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Melatonin acts as a regulator of sleep-wake cycles. The data provided does not include specific mechanism details for melatonin. For calcium, the data describes its role in bone mineralization and neuromuscular relaxation [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements. For calcium specifically, 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] [FDA data].
Our recommendation
Because data on this specific melatonin product is not available, we cannot make a specific recommendation. If you are considering calcium, be aware that it can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
