Vitamin World Extra Strength Melatonin 5 mg
Brand: Vitamin World · Form: TABLET [E0155]
Our assessment
Our assessment: Melatonin is a well-studied sleep aid, but the evidence shows that a 5 mg dose is significantly higher than what most people need. Data indicates that 0.5 mg to 3 mg is effective for sleep onset, and higher doses can lead to next-day grogginess [NIH ODS]. For many, starting with a lower dose is a more appropriate strategy than using this 5 mg product.
How it works
Think of melatonin as your body's internal "night signal." It is a hormone naturally produced by the pineal gland to regulate your sleep-wake cycle, telling your brain it's time to sleep [NIH ODS]. Taking a supplement can help shift your circadian rhythm, making it useful for jet lag, shift work, or general insomnia [NIH ODS].
Safety profile
Safety data is limited for this specific product. FDA received 5,471 adverse event reports for melatonin supplements overall [FDA data]. Side effects reported include headache, dizziness, nausea, and next-day drowsiness [NIH ODS]. Due to the high dose, these side effects may be more likely with this product. Long-term safety data for daily use beyond a few weeks is not available [NIH ODS].
Our recommendation
Our recommendation: Start with a much lower dose, such as 0.5 mg to 1 mg, taken 30-60 minutes before bed. This product's 5 mg strength is best reserved for short-term use under specific guidance, such as for jet lag or as directed by a healthcare provider. Do not drive or operate machinery for several hours after taking it [NIH ODS].
