Data not available for the specific formulation of this product.

How it works

Think of melatonin as your body’s natural sleep timer. It is a hormone that signals to your brain that it is time to prepare for sleep, helping to regulate your circadian rhythm. The 3mg dose is a common starting point to support falling asleep faster. Data not available for the specific mechanism of this product.

Safety profile

FDA received 592,059 total adverse event reports across all supplements. For this specific product, data is limited. General safety data for calcium, an unrelated ingredient, shows that high levels can cause constipation, nausea, and abnormal heart rhythms [NIH ODS]. However, these side effects are not directly applicable to melatonin. Data not available for Natrol Melatonin 3mg specific adverse events.

Our recommendation

Start with the lowest effective dose, typically 1mg to 3mg, taken 30 to 60 minutes before bedtime. Do not drive after taking it. Avoid using it every night for long periods without consulting your doctor. Data not available for a specific recommendation for this product.
