When to take Yu Sleep
Melatonin works best as a timing signal. Taken roughly 30 to 60 minutes before bed, it gives your body time to absorb the ingredients and start winding down just as you lie down. Taking it right as your head hits the pillow often means it starts working while you are already lying awake, and taking it several hours early can make you sleepy at the wrong time.
Consistency matters more than precision. Pick a time that fits your normal bedtime, such as 9:45 p.m. for a 10:30 p.m. bedtime, and stick to it on weekdays and weekends as much as you can. Your body clock learns from repetition.
If you wake up in the night
Do not take a second serving in the middle of the night. Extra melatonin late in the night is a common cause of morning grogginess. If night wakings are your main problem, focus on a consistent evening dose and the habits below, and give it a few weeks.
How to measure and take your serving
- Read the label. Check the serving size, which may be listed as a number of drops or a full or partial dropper.
- Start low. For the first three to five nights, use the smallest serving the label allows. This shows you how your body reacts before you settle on a routine.
- Use the method on the label. Many liquid supplements are held under the tongue for a short time before swallowing, while others are added to a small glass of water. Follow what your bottle says.
- Close the bottle tightly. Store it in a cool, dry place away from direct sunlight and out of reach of children.
- Note how you feel. A quick line in a notebook or phone app about how fast you fell asleep and how you felt in the morning is enough.
Do not exceed the serving on the label. More is not better with melatonin, and higher amounts of 5-HTP increase the chance of stomach upset.

Common mistakes

Special situations
Travel and jet lag
When crossing time zones, take your serving 30 to 60 minutes before bedtime in the new time zone, starting on the first night after you arrive. Getting outdoor light in the morning at your destination helps your body clock adjust faster.
Shift work
If you work nights, take Yu Sleep before your main sleep period, whenever that is, and keep your bedroom as dark as possible. Shift workers should talk to a doctor, as sleep problems with shift work often need a fuller plan.
Missed a night
Simply take your normal serving the next evening. There is no need to make up for a missed dose.
Taking breaks
Many people use sleep supplements for a few weeks to reset their routine, then take them only when needed. If you plan to use Yu Sleep nightly for several months, check in with your doctor.
Before starting, read about possible side effects and interactions.
