Doctor's Best Quick Melt Melatonin 2.5 mg
Brand: Doctor's Best · Form: TABLET [E0155]
Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health. However, for a melatonin supplement, the data provided does not support a specific health benefit for sleep. Our assessment is that the primary active ingredient here is calcium, not melatonin, based on the data we have. The recommended daily allowance for calcium is 1,000 mg for most adults, but this product provides only 2.5 mg, which is a negligible amount for bone support [NIH ODS].
How it works
Think of calcium as a structural builder for your bones and a signal regulator for your nerves and muscles. It supports bone mineralization and density, and it helps your muscles relax and your nerves send signals properly [NIH ODS]. The data does not explain how this small dose might work for sleep, so we cannot comment on that mechanism. For bone health, you would need a significantly higher dose than what is in this product [NIH ODS].
Safety profile
Data not available for this specific product. The FDA has received a total of 592,059 adverse event reports across all supplements, but a breakdown for this specific product is not provided [FDA data]. For calcium in general, very high intakes can cause constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and poor muscle tone [NIH ODS]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation is to proceed with caution. The data provided does not indicate that 2.5 mg of calcium is effective for any specific health purpose. If you are seeking a calcium supplement, you should aim for a product that provides a meaningful dose (e.g., 500-1000 mg) to support bone health [NIH ODS]. If you are looking for a melatonin supplement, the data does not confirm this product contains melatonin. Always consult your physician before starting any new supplement, especially if you take prescription medications [NIH ODS].
