Natural Factors Stress-Relax Melatonin 3 mg
Brand: Natural Factors Stress-Relax · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that melatonin is a well-studied supplement for supporting sleep onset, but the 3 mg dose in Natural Factors Stress-Relax Melatonin is a specific pharmacological dose, not a natural amount your body produces. For occasional sleep support, 3 mg is within the common range, but you should start with the lowest effective dose [NIH ODS].
How it works
Think of melatonin as a timing signal — it tells your brain that it is time to prepare for sleep. It works by binding to receptors in your brain that help regulate your circadian rhythm, promoting drowsiness and lowering body temperature to facilitate sleep onset [NIH ODS]. The 3 mg dose in this product is designed to provide a noticeable, reliable signal for most adults.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, but specific report counts for melatonin are not available in the provided data. Safety data from the NIH indicates that short-term use of melatonin at 3 mg is generally well-tolerated. Common side effects can include drowsiness the next morning, headache, or dizziness. You should not drive or operate machinery for several hours after taking this product [NIH ODS].
Our recommendation
Take this product 30 to 60 minutes before your desired bedtime. Do not use it for more than a few weeks without consulting your healthcare provider. If you have an autoimmune condition, are pregnant, or take blood thinners or immunosuppressants, speak with your doctor before use. For most people, this is a practical option for short-term sleep support [NIH ODS].
