Natrol Melatonin 5 mg

Our assessment

The evidence shows that you should be very cautious with this product. While the label indicates Natrol Melatonin 5 mg, the supplement facts and ingredient list are not provided here. The data we have is for the mineral calcium, which is a different substance entirely. Based on the information available, we cannot verify the claims or safety of this specific melatonin product. Data not available for melatonin-specific studies or mechanisms from the provided sources.

How it works

For the ingredient calcium, which is the only data provided, the mechanism involves bone mineralization and neuromuscular relaxation. Specifically, calcium supports bone density and mineral deposition, and it also helps with muscle relaxation and nerve signaling [NIH ODS]. This mechanism does not apply to melatonin, which is a sleep-regulating hormone.

Safety profile

The FDA received a total of 592,059 adverse event reports across all products in the database, but this number is not specific to Natrol Melatonin 5 mg [FDA data]. Based on the data for calcium, safety concerns include that high calcium intakes might increase the risk of heart disease and prostate cancer. High levels of calcium 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]. These side effects are not relevant to melatonin. No specific side effect reports or report counts for Natrol Melatonin 5 mg are available.

Our recommendation

Because the provided data pertains to calcium and not to melatonin, we cannot offer a confident recommendation for Natrol Melatonin 5 mg. The information on interactions—such as calcium reducing absorption of certain medications like bisphosphonates and levothyroxine—does not apply here [NIH ODS]. For a melatonin product, we advise you to consult a healthcare provider for personalized guidance. Data not available for melatonin-specific dosing or safety from the provided sources.

Supplement labels contain several key sections regulated by the FDA:

• Serving Size — The recommended amount per dose. Always check this — some products require multiple capsules per serving.
• Amount Per Serving — Shows the quantity of each nutrient in the product, typically in IU (International Units), mg (milligrams), or mcg (micrograms).
• % Daily Value (%DV) — Indicates how much a nutrient in a serving contributes to a daily diet. 5% DV or less is low; 20% DV or more is high.
• Other Ingredients — Lists inactive ingredients like fillers, binders, and capsule materials (e.g., gelatin, cellulose, magnesium stearate).
• Suggested Use — The manufacturer's recommended directions for taking the supplement, including timing and dosage.
