NutriCology Melatonin 20 mg
Brand: NutriCology · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that this product contains 20 mg of melatonin, which is a high dose. For context, the typical starting dose for sleep support is often much lower. Our assessment is that this dose is best suited for specific, short-term use under professional guidance, not for daily long-term supplementation without a clear reason. Data for the specific calcium content in this product is not available.
How it works
Melatonin is a master regulator of your sleep-wake cycle. It signals to your body that it is time to rest, helping to reduce the time it takes to fall asleep. While calcium is known to support bone mineralization and neuromuscular relaxation, its role in this specific product is unclear as the amount is not listed on the label [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements. For this specific high-dose melatonin product, side effects can include daytime drowsiness, dizziness, and headaches. Because the calcium content is not provided, we cannot assess the specific risk of side effects like constipation or nausea from calcium [FDA data]. Always start with a lower dose to see how you respond.
Our recommendation
We recommend starting with a much lower dose of melatonin, typically 0.5 mg to 5 mg, taken 30–60 minutes before bed. A 20 mg dose should only be used if specifically recommended by your healthcare provider for a condition like circadian rhythm disorder. Because the calcium content is not listed on the label, we cannot recommend this product for bone health support. Data not available for specific calcium content in this product.
