Allergy Research Group Melatonin 20 mg
Brand: Allergy Research Group · Form: CAPSULE [E0159]
Our assessment
The evidence shows that melatonin is a naturally occurring hormone that helps regulate your sleep-wake cycle. However, a dose of 20 mg is considered very high. Most adults do not need more than 5 mg, and starting at 20 mg significantly increases your risk of side effects. For most people, a lower dose of 0.5 to 5 mg is more appropriate for sleep support [NIH ODS].
How it works
Think of melatonin as your body's internal clock regulator. It is produced naturally in the brain's pineal gland in response to darkness, helping to signal your body that it is time to sleep [NIH ODS]. Taking a supplement like this 20 mg product works by increasing the level of this hormone in your blood, which can help you fall asleep faster, particularly if you have delayed sleep phase disorder or jet lag [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all dietary supplements. For this specific product, data on side effects is not available. However, melatonin in general can cause side effects including headache, dizziness, nausea, and drowsiness the next morning. Because this is a 20 mg dose, you are more likely to experience these effects [NIH ODS]. Do not drive or operate machinery for at least five hours after taking this supplement.
Our recommendation
We do not recommend starting with this 20 mg dose. You should begin with a much lower dose, such as 1 mg to 3 mg, taken 30 to 60 minutes before bedtime. If you are considering this specific product, please consult your doctor first. Melatonin can interact with blood thinners, diabetes medications, and immunosuppressants [NIH ODS].
