Our assessment
The evidence shows that Douglas Laboratories Melatonin 3 mg is a supplement designed to support sleep, but our assessment must be based strictly on the data provided. For this specific product, data on its primary ingredient—calcium—is available. Data on melatonin itself is not available in the provided materials. Therefore, our assessment focuses on the calcium content, noting that calcium is a mineral that supports bone density and muscle relaxation [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 works by supporting bone mineralization and mineral deposition to maintain strong bones, and it aids in neuromuscular relaxation, which helps your muscles and nerves function properly [NIH ODS].
Safety profile
Based on the data provided, there are 592,059 total adverse event reports across all supplements in the FDA database [FDA data]. Specific side effects for calcium include constipation, nausea, weight loss, extreme tiredness, and frequent need to urinate at high levels [NIH ODS]. High calcium intakes might also increase the risk of heart disease and prostate cancer. Additionally, calcium can reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS]. Data on side effects or report counts specific to this product or melatonin is not available.
Our recommendation
Data not available for a specific recommendation on melatonin. For the calcium component, ensure you do not exceed recommended intake levels and be aware of potential medication interactions. Consult your healthcare provider before starting this supplement, especially if you take prescription medications or have a history of kidney stones or heart disease [NIH ODS].
