At 1 mg per capsule, this gives you a clinically relevant dose of **Melatonin** for sleep onset support — right at the low end of the studied range (0.5–5 mg), where recent research suggests lower doses may work just as well as higher ones for helping you fall asleep. You're getting the dose many sleep researchers actually recommend, since higher amounts (3–5 mg) don't consistently improve outcomes and can cause more morning grogginess.
**Melatonin** has strong clinical evidence for reducing the time it takes to fall asleep and resetting your circadian rhythm, particularly useful if you're dealing with jet lag or shift work. The capsule format makes it easy to take the suggested single dose 30 minutes before bed.
The main limitation is that melatonin primarily helps with sleep onset — if your issue is staying asleep or sleep quality rather than falling asleep, you may not get the full benefit you're looking for. This product also contains no complementary sleep ingredients like magnesium or L-theanine, so it's purely a circadian rhythm tool.
