I bought Pure Encapsulations Melatonin-SR because my problem was never falling asleep — it was staying asleep. I’d drop off fine and then surface at 2 a.m., wide awake, with the rest of the night gone. Regular melatonin would put me down but didn’t seem to hold me there. That’s exactly the gap this extended release version is built for.

Quick verdict
If you fall asleep without trouble but wake up in the middle of the night, this is worth a try. Each capsule spreads 3 mg of melatonin out over roughly six hours, so you get a small, steady dose through the night instead of one spike that fades. It is not a fast knockout — if you need to fall asleep ASAP, take a regular melatonin and keep this as the “stay asleep” layer, which is exactly what I do. In my experience it does what the label says: keeps you down. check current price on Amazon
Why I bought it
Extended release was the main reason. I’d been through plain melatonin, and the effect felt front-loaded: strong enough to get me to sleep, but gone by the middle of the night when I actually needed help. Pure Encapsulations describes this as prolonged absorption for 6-hour support, and the math lines up with how I use it — 3 mg spread over 6 to 8 hours works out to a small dose per hour, something like a fraction of a milligram at a time. That’s a gentle, steady signal. I wanted something that covered the whole sleep window, not just the first hour.
I’ll admit the brand’s reputation played a part too. Pure Encapsulations is one of those supplement makers that publishes exactly what’s in each capsule and gets the finished product tested for potency and purity. For something I take every single night, that matters to me more than it would for a once-in-a-while pill.
What extended release melatonin is like to use
The capsules are small and easy to swallow, and the brand keeps the formula clean — just the active ingredient plus a short list of capsule materials, no junk. The listing says to take one capsule 30 to 60 minutes before bed, and that’s what I do.
The thing you notice is that it’s not dramatic. There’s no heavy hit, no feeling of being knocked out. The effect creeps in and then just stays. Since I’ve been taking it, the middle-of-the-night wake-ups are far less frequent. I sleep through, and I haven’t had the groggy next-morning feeling that some higher-dose melatonins gave me.
Here’s the system I actually run: I pair this with a plain 0.3 mg fast-release melatonin and scale by how I feel. Some nights are calm and 0.3 mg is plenty to get me under; other nights I need a bit more. Being able to step the fast-release dose up or down while this SR capsule handles staying asleep is the setup I’ve landed on, and it’s been working well.
One more note on consistency: a bottle is 30 capsules, a full month at one per night. I found I stay on schedule better when the whole month’s supply is in one bottle, and the capsules don’t have any noticeable taste, so there’s nothing to dread before bed.

Who should skip it
If your problem is lying there unable to fall asleep and you want something that works in twenty minutes, this is not it — you want a fast-release melatonin. And if you never wake up mid-night in the first place, a plain 3 mg capsule is simpler and cheaper. This is specifically for people who fall asleep fine and need the overnight coverage.
FAQ
Is extended release melatonin better than regular melatonin?
They solve different problems. Regular melatonin hits fast but fades, which is fine if you just need help falling asleep. Extended release spreads the dose over several hours, which is better if you fall asleep but wake up during the night. A lot of people, including me, end up using both.
How much melatonin is in each capsule?
3 mg per capsule, in a sustained-release form. Because it’s released over roughly six hours, you’re getting a small amount at a time across the night rather than the whole 3 mg at once — that’s the point.
When should I take Melatonin-SR?
Take one capsule 30 to 60 minutes before bed, per the label. Since the release is gradual, taking it too late means the effect peaks further into your sleep window than you want.
Bottom line
Melatonin-SR is a stay-asleep supplement, and it does that job well. If falling asleep is easy for you but staying asleep isn’t, this is what I’d grab — and pairing it with a low-dose fast-release melatonin gives you control over both halves of the night. check current price on Amazon
