🌙 Quick Verdict — Yu Sleep
Yu Sleep gets the most important detail right: a low 0.9 mg melatonin dose, close to what research suggests is effective, instead of the 5–10 mg many products use. Combined with calming nutrients like magnesium, L-theanine and apigenin, it is a gentle, well-designed sleep aid. Our rating: 8.8/10.
What Is Yu Sleep?
Yu Sleep (Yu Sleep Drops) is a sleep-support supplement in liquid form. You take a 2 mL serving — two droppers — about 30 minutes before bed. Each bottle holds 30 servings.
It is designed for adults who have trouble winding down, falling asleep or staying asleep, and who want a natural, non-habit-forming option.
Yu Sleep Ingredients (Per 2 mL)
Melatonin0.9 mg
The hormone that signals "night" to your body clock. Low doses like this are often as effective as high doses, with less next-day grogginess.
Magnesium glycinateblend
Supports muscle relaxation and calm; the glycinate form is gentle and glycine itself is studied for sleep quality.
Red tart cherry concentrateblend
A natural source of melatonin; small studies link tart cherry to longer sleep time.
Apigenin & lemon balmblend
Apigenin (found in chamomile) and lemon balm are traditional calming botanicals.
L-theanine & GABAblend
L-theanine promotes relaxation without sedation; GABA is the brain's main calming neurotransmitter.
5-HTPblend
A precursor to serotonin, which the body converts into melatonin.
Vitamins B2 & B6 (active forms)0.5 mg each
B6 is a cofactor in making serotonin and melatonin.
Why a Low Melatonin Dose Is a Plus
Many US sleep products contain 5–10 mg of melatonin. Research suggests far lower doses (around 0.3–1 mg) can be just as effective for shifting the body clock — and higher doses are more likely to cause morning grogginess and headaches. Yu Sleep's 0.9 mg is a thoughtful choice.
Side Effects & Safety
Do not drive or operate machinery after taking it. 5-HTP should not be combined with antidepressants (SSRIs, SNRIs, MAOIs) or other serotonergic drugs. Talk to your doctor if you take sedatives, blood pressure medication or blood thinners, are pregnant or nursing, or have an autoimmune condition. Not for children.

Yu Sleep FAQs

How much melatonin is in Yu Sleep?
0.9 mg per 2 mL serving.
Can I take Yu Sleep with antidepressants?
No, not without your doctor's approval — it contains 5-HTP.
Will I feel groggy in the morning?
The low melatonin dose makes grogginess less likely than with high-dose products, but everyone reacts differently.
Final Verdict
