How Long Before Bed to Take Melatonin.

The short answer: Take Betterly's 10mg Melatonin Sleep Capsules 20 to 30 minutes before bedtime, with an 8 oz (237 ml) glass of water. That's how our label answers "how long before bed should you take melatonin?" Other brands can print other windows, so go by the bottle you own. Our 1mg strip and valerian capsule say "daily" without a clock time. And if bedtime passed hours ago, sit that night out.

Key takeaways

• Of our three melatonin labels, only the 10mg Melatonin Sleep Capsules print a timing window: 20 to 30 minutes before bedtime.
• Our 1mg strip and valerian capsule labels say "daily" and give no time, so any minute count for them would be a guess.
• Winding down tonight and moving your body clock earlier are separate timing questions, and the second belongs with a healthcare provider.
• A serving taken deep into the night leaves fewer hours before your alarm, and NCCIH lists sleepiness among melatonin's possible side effects.
• A week of fixed bedtimes alone, then a week adding the label serving, tells you more than any single night can.

Full disclosure: Betterly sells 10mg Melatonin Sleep Capsules, 1mg Melatonin Sleep Strips and Valerian & Chamomile Sleep Capsules, so we'd like you to buy one. Only one of those three labels answers the timing question. We quote all three as printed, gaps included.

How long before bed should you take melatonin?

How long before bed you should take melatonin depends on the product: our 10mg capsule's label says 20 to 30 minutes, and many other labels give no window.

Search the question and you'll see answers from half an hour to a few hours. We couldn't match most of them to a federal page, so we won't repeat them as rules.

NCCIH, the federal center for complementary health research, has a melatonin fact page that tells anyone using a supplement like melatonin to "read and follow label instructions." Our 10mg bottle's instructions are specific: two capsules and a full glass of water, counted back from bedtime.

So the real question is often "When is my bedtime?" A window counted back from bedtime only works when bedtime stays put.

What do our melatonin labels say about timing?

Of Betterly's three melatonin labels, only the 10mg Melatonin Sleep Capsules name a time, while the strip and the valerian capsule say "daily" and stop there.

The takeaway: the product with the most melatonin is also the one with the clearest clock. The other two pair melatonin with valerian, so we'd read their "daily" as "in the evening" and leave it there.

Whether 10 mg is more than you need is covered in our guide on whether 10mg of melatonin is too much. You can compare all three panels in our sleep and stress relief collection.

How long does melatonin take to kick in?

No federal source we checked gives a kick-in time for melatonin supplements, so the 10mg label's bedtime window is the closest answer our shelf offers.

That window comes from the manufacturer's directions. We didn't time it ourselves.

What you can shape is the room. NCCIH warns that exposure to light at night can get in the way of the melatonin your body makes on its own. So once the serving is down, dim the lamps and park the phone across the room.

Strip-versus-capsule speed is a format question, covered in our guide to sublingual vs swallowed melatonin.

How long does melatonin last into the next morning?

How long melatonin lasts into your morning is easiest to judge by the hours between your serving and your alarm, since the 10mg label ties its serving to bedtime.

MedlinePlus, the National Library of Medicine's health site, puts the general sleep need for adults at 7 to 9 hours a day. Set that against a 6:30 a.m. alarm:

• A serving at 10:30 p.m. leaves 8 hours.
• A serving at 12:30 a.m. leaves 6 hours.
• A serving at 2:30 a.m. leaves 4 hours, well short of that range.

Sleepiness is one of the mild side effects NCCIH lists for melatonin, and a late serving gives it less night to wear off. If you wake up foggy, check the clock time of your last serving first. Everything after the alarm is the subject of our guide to feeling groggy after melatonin.

What if it's already 2 a.m.?

If it's 2 a.m. and your alarm is set for 6, we'd skip melatonin that night. The 10mg label ties its serving to bedtime, and 2 a.m. is long past the one most people planned.

Awake again after a bedtime serving? Don't take a second. The 10mg label says two capsules once a day, and all three labels say "Do not exceed recommended dose." MedlinePlus suggests a different move: if you can't fall asleep for 20 minutes, get up and do something relaxing.

Does timing change when you're shifting your sleep schedule?

Timing melatonin to shift your sleep schedule is a different goal from winding down tonight, and NCCIH's example of it paired the serving with a fixed bedtime.

NCCIH describes melatonin as a hormone that helps with the timing of your circadian rhythms, your roughly 24-hour internal clock, and with sleep. So people ask it to do two jobs:

• Winding down tonight. Your bedtime is normal. Our 10mg label's window is written for this.
• Moving your clock. Your sleep has drifted hours later than you'd like.

For the second job, NCCIH summarizes a 4-week clinical trial with 307 participants, all with a clinically diagnosed sleep-timing problem. Participants took melatonin 1 hour before a chosen bedtime and went to bed at that set time. As a patient study, its protocol doesn't carry over to a night owl who simply stays up late, and it isn't what our label prints. If moving your clock is the goal, bring the plan to a healthcare provider.

Travel is its own case. Our jet lag melatonin timing guide covers flights east and west.

How do you take each of our melatonin products?

Betterly's 10mg Melatonin Sleep Capsules go down as two capsules, once a day, 20 to 30 minutes before bedtime, with an 8 oz (237 ml) glass of water.

The label as steps, plus one rule of our own:

1. Choose a bedtime you can keep. The window counts back from it.
2. Set a reminder for 25 minutes before. That lands inside the window with slack either way.
3. Take both capsules with a full glass of water. Two capsules make up the 10 mg serving.
4. Start winding down. Lamps low, screens away, car keys out of reach.
5. Stop at one serving. Each label says not to exceed its recommended dose, so we'd use one melatonin product per night and never two together.

The capsule's sleep formula blend, 905 mg per 2-capsule serving, lists St. John's wort, L-tryptophan and 5-HTP among its 14 ingredients, without separate amounts.

For the strips, the label's suggested use is "Place 1 oral strip on the tongue daily and allow it to dissolve." Each 1-strip serving lists 1 mg of melatonin and 50 mg of valerian root extract.

For the valerian capsules, the label says "adults take two (2) capsules daily," with 6 to 8 oz (177 to 237 ml) of water. Each 2-capsule serving lists 2 mg of melatonin, 150 mg of valerian extract and 100 mg of L-tryptophan.

Neither label names a time, so ask a pharmacist if you want a set routine. How the herb in both compares with melatonin is covered in our valerian root vs melatonin guide.

From our shop: 10mg Melatonin Sleep Capsules — the only one of our three melatonin labels that prints a bedtime window, with 10 mg of melatonin per 2-capsule serving.

How can you test your melatonin timing over two weeks?

A two-week melatonin timing test compares one week of fixed bedtimes alone with one week adding the label serving, so you can see what the serving itself changes.

By Thursday, you won't remember whether Tuesday was the late-coffee night. A log fixes that, and the test uses just 7 of a bottle's 30 servings.

• Week one, no melatonin. Pick a bedtime and a wake time, keep both all 7 days, and dim the lights for the last half hour.
• Week two, same routine plus the label serving. For the 10mg capsule, use the reminder from the steps above. For the strip or the valerian capsule, use the evening time your pharmacist helped you pick.
• Each morning, fill in one row.

Put the two weeks side by side. If week two reads like week one, melatonin may not be the missing piece. If the gap column stretches past an hour, or Saturday's drift keeps showing up, fix the schedule before you judge the product. If morning scores slip in week two, check your serving times, then talk to a healthcare provider.

NCCIH says short-term use appears safe for most people, but long-term safety information is lacking. A test with an end date respects that gap.

From our shop: 1mg Melatonin Sleep Strips — 1 mg of melatonin per 1-strip serving, the lowest of our three melatonin labels, in a raspberry-flavored strip you let dissolve on your tongue.

When should you skip a melatonin serving?

Skip a melatonin serving when bedtime is long gone, when an early drive comes next, or when your nights already start on time and sleep comes easily.

Beyond the 2 a.m. case above, plan for three more:

• An early start follows a short night. Sleepiness is a possible melatonin side effect, and a 4 a.m. alarm leaves little time for it to clear before you're behind the wheel. Try any new serving time on a night before a day off.
• The trouble sits at the other end of the night. If you drift off fine and wake before the alarm, a serving tied to bedtime is aimed at the wrong hour. A steady wake time and daytime sunlight, both on MedlinePlus's list, are the free first steps.
• Another sleep product is already in your system tonight. The 10mg blend lists 5-HTP and L-tryptophan, the valerian capsule lists 100 mg of L-tryptophan per 2-capsule serving, and both lower-dose products carry valerian. Adding one on top of another stacks ingredients that no single label planned for.

Who should check with a healthcare provider first?

Check with a healthcare provider before taking melatonin if you're pregnant, nursing, under 18, managing a medical condition, taking any medicine or sleeping on a shifting work schedule.

Each of our three labels carries the same caution: "Do not exceed recommended dose. Consult a physician if pregnant, nursing, under 18, or have a medical condition." Timing adds a few cases of its own:

• Night or rotating shifts. Our 10mg label counts back from a bedtime, which is hard to do when bedtime jumps with your shifts. Plan daytime sleep with a provider first.
• Older adults with a late serving. NCCIH says melatonin may remain active for longer in older people than in younger adults and cause daytime drowsiness, so a serving pushed toward midnight leaves less margin.
• Evenings with alcohol or a sedative. The strip and the valerian capsules both list valerian, and NCCIH's valerian page says it shouldn't be taken along with alcohol or sedatives.
• Any medicine. NCCIH says anyone taking medicine should consult a provider before using melatonin, and blood-thinner users need medical supervision. The 10mg blend adds St. John's wort, which NCCIH's St. John's wort page says can weaken many medicines, birth control pills among them.
• Pregnancy and nursing. NCCIH notes a lack of research on melatonin safety in pregnant or breastfeeding women. The 10mg blend carries a second flag here, since that same St. John's wort page says the herb may be unsafe during pregnancy.

FAQ: melatonin timing

How long before bed should you take 10mg melatonin?

Betterly's 10mg Melatonin Sleep Capsules label says to take two capsules 20 to 30 minutes before bedtime with an 8 oz (237 ml) glass of water. "Bedtime" means the one you'll actually keep that night. If Saturday's lights-out runs an hour later, move the serving an hour later too. Other 10 mg brands may print different directions.

How many hours before bed should you take melatonin?

None of our three melatonin labels asks for a serving hours ahead: the 10mg capsule counts back in minutes, and the other two name no time. The one federal example we found of a 1-hour lead is a trial NCCIH describes in people with a diagnosed sleep-timing problem, which also fixed their bedtime, so it isn't a general rule. A lead of an hour or more is a plan to build with a healthcare provider before you try it.

When should you take melatonin, morning or night?

Take melatonin at night. Our 10mg label ties its serving to bedtime, and while the strip and valerian capsule labels just say "daily," both are sleep formulas that pair melatonin with valerian, so evening is our own reading for those two. NCCIH lists sleepiness as a possible melatonin side effect, so a morning serving, or one before driving, doesn't fit.

Should you take melatonin with food or on an empty stomach?

None of Betterly's three melatonin labels mentions food. The capsule labels ask for a glass of water, and the strip dissolves on your tongue with no water listed. We won't guess which works better, but a pharmacist can answer that for your routine.

Should you take melatonin before a nap?

Betterly's melatonin labels don't mention naps, and the 10mg label ties its once-a-day serving to bedtime, so we wouldn't use it for a nap. MedlinePlus suggests skipping naps after 3 p.m. If you rest earlier in the day, let it be a plain nap, and save the serving for the bedtime the label names.
