Sisu Sisu - Melatonin 5mg, 90 sub
Sisu Melatonin - 5 mg - Melatonin can help people with low melatonin levels fall asleep more easily, sleep longer and wake up less frequently by resetting an internal clock disrupted by jet lag, daylight savings time, or shift work. Tiny, fast-acting sublingual tablets with natural mint flavour work quickly to improve sleep quality and can be started a few days before you expect your normal schedule to be altered.

What the research supports
One sublingual tablet dissolves under the tongue with 5 mg of melatonin. 90 tablets is three months at one a night.
Studies use 0.5 to 5 mg a night.
- Sleep onset (evidence: strong, from meta-analysis, randomized controlled trial)
- Melatonin tells the brain that night has begun, and dissolving under the tongue lets some of it reach the blood directly rather than through the gut. Trials show it shortens time to fall asleep by seven to twelve minutes at 0.5 to 5 mg.
- Jet lag (evidence: strong, from meta-analysis, randomized controlled trial)
- Taken at the destination's bedtime, melatonin resets the body clock to the new time zone and lowers daytime tiredness after travel, most clearly on eastward trips across five or more zones.
- Body clock (evidence: moderate, from randomized controlled trial)
- Evening melatonin nudges the internal clock earlier, and timing the dose matters more than the milligram count. Taking it at the same bedtime each night shifts sleep and wake times gradually forward.
- Staying asleep (evidence: mixed, from randomized controlled trial)
- Because it clears the bloodstream within a few hours, melatonin does more to start sleep than to hold it. It helps falling asleep consistently, with far less effect on waking mid-night.

Is it right for you
Worth it if
- Flying east across three or more time zones
- Starting a few days before the schedule shifts and dosing at the new bedtime is exactly how the travel research is run.
- Someone who lies awake for an hour at lights out
- A sublingual peaks faster than a swallowed tablet, so it can be taken close to the moment you actually get into bed.
- People who cannot swallow pills
- The tablet is small enough to dissolve under the tongue in a mint base, with no water needed.
Look elsewhere if
- Someone who wakes at 3 am and stays awake
- an extended-release melatonin, or 200 to 300 mg of magnesium at night, since a fast sublingual peak is largely gone by the small hours.
- A cautious first-time melatonin user
- 0.5 to 3 mg. Sublingual delivery makes this 5 mg land harder than the number suggests, so half a tablet is a fairer starting point.
- Anyone whose gut reacts to sugar alcohols
- a plain swallowed melatonin tablet, since the dissolving base here is isomalt.
What to expect
Sleepiness generally shows up 20 to 30 minutes after the tablet dissolves. It is a nudge rather than a switch, and it works best in a dark room with screens off, because light undoes the signal you just took. For travel, expect the clock to move about an hour a day rather than all at once.
How it compares
- Compared with a standard 5 mg swallowed melatonin tablet
- Dissolving under the tongue skips the liver's first pass, so more of the 5 mg reaches the blood and it gets there in roughly half the time. The tradeoff: You have to hold it in your mouth and accept mint and isomalt, and a faster rise means a faster fall, so it does less for the back half of the night.
- Compared with the 10 mg tablet
- 5 mg is much closer to the doses research actually uses, with less next-day heaviness for the same effect on falling asleep. The tradeoff: If you are sleeping days on a night shift schedule, the larger dose has more direct trial support.
