LifeSource Vitamins Melatonin 5 mg delivers a balanced, research-driven formula designed to support restful sleep, improve circadian rhythm alignment, and promote stress resilience. Each vegan capsule provides 5 mg of melatonin, produced in FDA-registered, GMP-certified facilities and supported by NIH-indexed human clinical studies. Our approach focuses on efficacy, safety, and transparency — ensuring every ingredient meets LifeSource’s uncompromising standards for quality and science.* Non-GMO, gluten-free, vegan.

Research Promise: At LifeSource Vitamins, our commitment is rooted in research and results. Every benefit below is supported by human clinical studies indexed in the National Institutes of Health (NIH) via PubMed, with full texts available in the National Library of Medicine (NLM) PubMed Central (PMC) when available. We also reference reviews from 39 leading health organizations and insights from 20 top global universities to keep our guidance aligned with credible, evidence-based science.* Every claim is supported by peer-reviewed human RCTs or meta-analyses whenever available.

Clinically Studied Benefits (Human Evidence)

• Melatonin reduces sleep-onset latency and modestly increases total sleep time in primary sleep disorders (systematic review/meta-analysis) (NIH/PubMed — Ferracioli-Oda E, 2013)
• Exogenous melatonin improves sleep latency (~4 min), total sleep duration (~13 min) and efficiency (~2.2%) vs placebo (meta-analysis) (NIH/PubMed — Brzezinski A, 2005)
• For delayed sleep–wake phase disorder, timed melatonin with light/schedule therapy advances circadian phase (~34 min) and improves sleep timing (RCT) (NIH/PubMed — Sletten TL, 2018)
• Melatonin is effective for jet lag when crossing multiple time zones (Cochrane review) (NIH/PubMed — Herxheimer A, 2002)
• Melatonin supplementation improves sleep quality (PSQI) across randomized trials (systematic review/meta-analysis) (NIH/PubMed — G F, 2021)
• Evidence in older adults supports modest benefits for sleep parameters (systematic review) (NIH/PubMed — Auld F, 2017)
• Low-dose melatonin improves circadian alignment in shift workers (RCT) (NIH/PubMed — Chellappa SL, 2021)

Additional / Promising Evidence*

• Dose–response/low-dose investigations suggest benefits on sleep timing/latency; more research needed to define optimal micro-doses (NIH/PubMed — Zhao CN, 2024)
• Adjunct circadian support in shift-work contexts shows improvements in circadian alignment and related outcomes (NIH/PubMed — Chellappa SL, 2021)
• Melatonin may enhance mitochondrial function for better recovery from sleep debt (NIH/PubMed — Grandner MA, 2021)
• Low-dose melatonin shows promise for adolescent sleep onset in neurodevelopmental disorders (NIH/PubMed — Zhang Y, 2020)

University / Academic Context

• Harvard Medical School – education materials note timing-dependent effects of melatonin on circadian phase
• Johns Hopkins – clinician resources discuss low-dose melatonin for sleep-onset support
• Oregon State University (Linus Pauling Institute) – monographs describe roles in circadian regulation and antioxidant biology

Global Evidence & Authoritative Reviews

• Clinical practice guideline for intrinsic circadian rhythm sleep–wake disorders recommends timed melatonin for DSWPD and related conditions (NIH/PubMed — Auger RR, 2015)
• Narrative/umbrella reviews summarize melatonin’s utility alongside light/schedule therapy for circadian disorders (NIH/PMC — Sun SY, 2022)
• Jet-lag effectiveness supported by Cochrane review (see Clinical section above) (NIH/PubMed — Herxheimer A, 2002)

We monitor research from leading institutions — Harvard, Johns Hopkins, Mayo Clinic, Cleveland Clinic, Cambridge, Oxford, Stanford, Yale, Tufts, University of Florida, Oregon State University – Linus Pauling Institute, Columbia, Cornell, Ohio State — to align with credible science.*
