The Claim
Many people believe that melatonin can completely cure insomnia and is effective for anyone who struggles with sleep. This belief stems from its popularity as a natural sleep aid.
Origin
The myth is perpetuated by marketing claims from supplement manufacturers and anecdotal success stories shared in the media and online forums.
What Science Says
Research indicates that melatonin can be effective in regulating sleep-wake cycles, particularly for people with circadian rhythm disorders or jet lag. However, multiple meta-analyses and randomized controlled trials (RCTs) have shown that its effect on primary insomnia is modest, with improvements in sleep latency and duration being small to moderate at best.
Verdict
Mostly False
