At 3 mg per capsule, you're getting **Melatonin** right in the middle of the clinically studied range (0.5–5 mg) for supporting sleep onset and circadian rhythm regulation. One capsule taken 30 minutes before bed — as the label suggests — delivers enough to help you fall asleep faster, with strong clinical backing from multiple trials.

Interestingly, research shows that lower doses (0.5–1 mg) can be just as effective as higher ones for sleep onset, while higher doses don't necessarily work better and may increase grogginess the next morning. At 3 mg, you have room to split capsules or reduce your dose if you find it's more than you need.

The main thing to know: melatonin helps with falling asleep and resetting your sleep schedule (jet lag, shift work), but it's not designed to keep you asleep through the night. If you're waking up at 3 AM, this likely won't solve that — it's a sleep-onset tool, not a sleep-maintenance one.
