Natural Factors Tranquil Sleep helps you fall asleep faster and stay asleep through the night without morning grogginess. Unlike habit-forming sleep medications, this natural formula works with your body's existing sleep mechanisms. The result is consistent, refreshing sleep that leaves you alert the next day.
Why It Works
SUNTHEANINE L-THEANINE (200 mg): The clinically studied form of L-Theanine that promotes relaxation without sedation — unlike regular L-Theanine which can be inconsistent.
5-HTP (30 mg): Supports natural serotonin production, which your body converts to melatonin for healthy sleep-wake cycles.
MELATONIN (3 mg): Works directly with your circadian rhythm to signal bedtime, helping you fall asleep more quickly.
What's Inside
Easy-to-swallow softgels with no artificial colors or unnecessary fillers. Made in Canada by Natural Factors under strict quality standards.
Why we carry it: Natural Factors consistently delivers research-backed formulas with clinically studied ingredients like Suntheanine — the real difference in sleep support quality.

Bad reaction
Product did not work as advertised, body felt numb, but revved up my brain, and it actually kept me awake all night

Didn’t help me
I’ve taken the sleep supplement for two weeks in a row now and honestly I haven’t slept any better than when I wasn’t taking it.

Restful nights sleep
I’ve been using the softgels for over a year now and they do exactly what they say. Promotes a restful nights sleep so you wake up refreshed and alert.
I find taking 1, 45 mins before I want to fall asleep is best. Great natural product.
