Can a supplement help with sleep?
Sleep problems have many possible causes. This page can help you explore them, but it cannot diagnose insomnia or give you a personal sleep schedule.
Trouble sleeping can mean difficulty falling asleep, waking in the night or feeling tired during the day. Pain, breathing problems, mood, medicines and other factors can play a part. A supplement label cannot tell you the cause. If sleep problems are persistent or severe, speak to a health professional.12

Measure the right outcome
What is bothering you most: getting to sleep, waking during the night, sleeping for too little time, or feeling tired during the day? These are connected, but they are not the same problem.
Sleep problems and stress can overlap; the stress and mood guide explains when to seek support.12
Routine and context
A regular sleep schedule, daylight and physical activity can support sleep. If problems are persistent or severe, talk to a health professional rather than relying on a routine alone.12
Check medicines and interactions
Some medicines and supplements cause drowsiness; combining them can be risky. Stimulants can make you feel more awake without making up for lost sleep. A pharmacist can check your medicines and supplements together.345
Melatonin
Melatonin can help with some sleep-timing problems, but it is not a general answer to every sleep problem. Evidence, product rules and timing depend on the situation and country. Read melatonin and sleep.
Caffeine and sleep
Caffeine can help you feel alert, but it can also make it harder to sleep or reduce sleep quality. It is found in drinks, some medicines and supplements. Read caffeine and sleep.
CBD and sleep
CBD products are often marketed for sleep, but products differ and studies do not settle every claim. Read what the evidence says about CBD and sleep.
5-HTP
The evidence for 5-HTP and sleep has limits, and interactions with medicines matter. Read 5-HTP, sleep and safety.
Epitalon and melatonin
The peptide, an older extract and the sleep-timing hormone are different substances. Understand epitalon, melatonin and sleep.67
Growth-hormone peptides and sleep
Some peptides are marketed for sleep, but a growth-hormone change does not establish better sleep. Explore the signal and the claims.
