Wonder Laboratories Melatonin 5 mg

Brand: Wonder Laboratories · Form: SOFTGEL CAPSULE [E0161] On Market

Our assessment

The evidence shows that melatonin can be an effective short-term aid for certain sleep issues, but the 5 mg dose in this product is higher than what many people need to start with. For general sleep support, 0.5 mg to 3 mg taken 30-60 minutes before bed is often sufficient, and starting at a lower dose can help you assess your sensitivity [NIH ODS].

How it works

Think of melatonin as your body's natural "darkness signal." Your brain produces it in response to darkness to help regulate your sleep-wake cycle. A 5 mg supplement provides a significant boost to this natural signal, which can be helpful for jet lag, shift work, or delayed sleep phase syndrome [NIH ODS].

Safety profile

Data not available for specific side effect report counts from the FDA data provided for this product. Generally, short-term use of melatonin is considered safe for most adults. Common side effects can include headache, dizziness, nausea, and drowsiness the next day [NIH ODS]. Because the 5 mg dose is higher than typical starting doses, you may be more likely to experience morning drowsiness [NIH ODS].

Our recommendation

If you are considering this 5 mg product, we recommend starting with a lower dose of melatonin (1-3 mg) first to see how you respond. If you have specific needs like jet lag or shift work sleep disorder, you may need a higher dose, but it is best to consult with your healthcare provider. Do not drive or operate machinery for several hours after taking it [NIH ODS].
