Superior Source Melatonin 10 mg
Brand: Superior Source · Form: TABLET [E0155]
Our assessment
The evidence shows that this product contains 10 mg of melatonin, a dose that is significantly higher than the 0.5 mg to 5 mg typically studied for sleep support. Data for the specific ingredient calcium, which is also listed, indicates it is essential for bone health, but the 10 mg melatonin dose warrants caution [NIH ODS].
How it works
Melatonin is a hormone that helps regulate your sleep-wake cycle. Think of it as a signal to your body that it is time to rest. For calcium, its role is different — it acts as a structural support for your bones and a regulator for nerve and muscle function [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements, though specific numbers for this product are not available. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High levels in the blood and urine can cause poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [FDA data] [NIH ODS].
Our recommendation
Start with a lower melatonin dose, typically 0.5 mg to 3 mg, and only use it for short-term sleep issues. Because this is a 10 mg dose, you should consult your healthcare provider before use. Also, be aware that calcium can reduce the absorption of medications like bisphosphonates and thyroid medication, so take them at different times of day [NIH ODS] [FDA data].
