A 2023 study shows that melatonin supplementation can impair morning cognition in healthy young adults. The findings suggest potential risks for those taking melatonin regularly, especially in the morning.
A 2023 study has found that melatonin supplementation impairs morning cognitive performance in healthy young adults. The research indicates that melatonin, commonly used as a sleep aid, may have unintended effects on alertness and mental function the morning after intake, raising concerns for consumers and healthcare providers.
The study, conducted by researchers at a university in the United States, involved healthy volunteers aged 18 to 25 who took melatonin supplements before sleep. The participants’ cognitive performance was tested the following morning through a series of tasks measuring memory, attention, and executive function. Results showed a statistically significant decline in performance compared to a placebo group.
According to the study published in a peer-reviewed journal, melatonin doses used in the experiment were comparable to typical over-the-counter supplements. Researchers noted that the impairment was most evident within the first few hours after waking, suggesting that melatonin’s effects extend beyond sleep regulation and may influence alertness and cognitive abilities.
Implications for Young Adults Using Melatonin
This research challenges the common perception that melatonin is a safe and benign sleep aid, especially for young, healthy individuals. The findings imply that regular or morning use of melatonin could impair mental performance, which might affect daily activities such as studying, working, or driving. Healthcare providers may need to reconsider recommendations for melatonin use, emphasizing caution or alternative strategies for sleep management.

Previous Assumptions About Melatonin’s Safety and Use
Melatonin has become increasingly popular as an over-the-counter supplement to aid sleep, with many assuming it has minimal side effects. Prior studies have primarily focused on its safety profile in older adults or individuals with sleep disorders. Few investigations have examined its impact on cognitive function in healthy young adults, especially during daytime hours.
This new study fills a gap by systematically evaluating cognitive outcomes following melatonin intake in a young, healthy population, revealing potential risks that had not been fully appreciated.
Unclear Long-Term Effects and Dosage Impacts
It remains uncertain whether these cognitive effects are transient or could have longer-term implications with repeated use. The study examined short-term outcomes, and the impact of different doses or formulations is still being investigated. Additionally, individual differences in metabolism and sensitivity to melatonin could influence results.
Further Research and Practical Guidelines for Use
Researchers plan to conduct longitudinal studies to assess long-term effects and optimal dosing strategies. Healthcare providers may need to update guidance on melatonin use, particularly for individuals who require alertness during morning hours. Consumers should stay informed about emerging evidence and consider timing when taking melatonin supplements.
Key Questions
Does melatonin affect everyone the same way?
No, individual responses vary based on factors like age, metabolism, and dosage. The recent study focused on healthy young adults, but effects may differ in other populations.
Should I stop taking melatonin if I experience morning grogginess?
If you notice cognitive or alertness issues after taking melatonin, consult a healthcare professional. Adjusting timing or dosage may help mitigate effects.
Is melatonin safe for regular use?
While generally considered safe for short-term use, recent findings suggest caution with regular or morning use, especially in young adults. More research is needed to establish safety guidelines.
What alternatives are available for sleep issues?
Non-pharmacological approaches such as sleep hygiene, cognitive behavioral therapy for insomnia (CBT-I), and lifestyle modifications are recommended. Consult a healthcare provider for personalized advice.
