Melatonin and Methylphenidate: what the published research says

PubMed indexes 8 records that name Melatonin and Methylphenidate together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.

Read this first

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Melatonin and Methylphenidate. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.

The research

8 studies naming Melatonin and Methylphenidate.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Is S100B Involved in Attention-Deficit/Hyperactivity Disorder (ADHD)? Comparisons with Controls and Changes Following a Triple Therapy Containing Methylphenidate, Melatonin and ω-3 PUFAs.

Nutrients · 2023 · PMID 36771418

Clinical Trial

“Our results agree with the hypothesis of glial damage in ADHD. Further studies on the link between DA and S100B are required to explain the transient increase in S100B following TT.”

Ouadih-Moran et al. · Authors' conclusion

Names both Melatonin and Methylphenidate in its title.

Methylphenidate ameliorates depressive comorbidity in ADHD children without any modification on differences in serum melatonin concentration between ADHD subtypes.

International journal of molecular sciences · 2014 · PMID 25257531

Clinical Trial

“In untreated children, partial homeostatic restoration of disrupted neuroendocrine equilibrium most likely led to an increased serum melatonin in PHI/CD children. A differential cerebral melatonin metabolization after methylphenidate may underlie some of the clinical benefit.”

Cubero-Millán et al. · Authors' conclusion

Names both Melatonin and Methylphenidate in its title.

Effects of co-administered melatonin and methylphenidate on cognitive impairment and histopathological alterations in an AlCl₃-induced neurotoxicity model of alzheimer's disease in BALB/C mice.

Scientific reports · 2026 · PMID 42036434

Animal study

“Histological examinations revealed increased neuronal density and CA1 hippocampal volume. These findings demonstrate that co-treatment with melatonin and MPH mitigates key pathological features of AD, suggesting a promising combinatorial strategy for targeting oxidative stress, neuroinflammation, and apoptosis in Alzheimer’s disease.”

Mohammadi et al. · From the abstract

Names both Melatonin and Methylphenidate in its title.

Methylphenidate effects on blood serotonin and melatonin levels may help to synchronise biological rhythms in children with ADHD.

Journal of psychiatric research · 2013 · PMID 23088865

Human subjects179 participants

“Chronic treatment with prolonged release methylphenidate induces subtle changes in the daily fluctuations and concentrations of both serotonin and melatonin. Improvement in Children's Depression Inventory (CDI) scores was not related to a morning increase in serotonin.”

Molina-Carballo et al. · Authors' conclusion

Names both Melatonin and Methylphenidate in its title.

Dietary intake, growth and development of children with ADHD in a randomized clinical trial of Ritalin and Melatonin co-administration: Through circadian cycle modification or appetite enhancement?

Iranian journal of psychiatry · 2012 · PMID 23139692

“Administration of melatonin along with ritalin improves height and weight growth of children. These effects may be attributed to circadian cycle modification, increasing sleep duration and the consequent more growth hormone release during sleep.”

Mostafavi et al. · Authors' conclusion

Names both Melatonin and Methylphenidate in its title.

Melatonin effects in methylphenidate treated children with attention deficit hyperactivity disorder: a randomized double blind clinical trial.

Iranian journal of psychiatry · 2012 · PMID 22952551

“Administration of melatonin along with methylphenidate can partially improve symptoms of sleep disturbance. However, it does not seem to reduce attention deficiency and hyperactivity behavior of children with ADHD.”

Mohammadi et al. · Authors' conclusion

Names both Melatonin and Methylphenidate in its title.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Melatonin, Methylphenidate, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
