Where Our Science Comes From: Built on the National Institutes of Health (NIH) Family, 39 Leading Health Organizations, and 10 Premier Universities Worldwide
At LifeSource Vitamins, we build our product pages and educational content on verifiable human clinical studies. Our core starts with the National Institutes of Health (NIH) and PubMed, supported by PubMed Central (PMC). We broaden this foundation with evidence and reviews from a select network of 39 respected health organizations and 10 premier universities worldwide for cross-validation and deeper insight. At LifeSource Vitamins, we believe the supplements you choose should be grounded in real, verifiable science — not hype. By drawing from the NIH, PubMed, and this broad network of respected organizations and universities, we ensure the benefits we describe are supported by the strongest available human clinical evidence. This approach gives you greater confidence that the products you choose are formulated with integrity and transparency.
The National Institutes of Health (NIH) and PubMed form our core evidence base. We further strengthen and verify findings by referencing 39 leading health organizations and 10 premier universities worldwide.*
What is PubMed?
PubMed, maintained by the National Institutes of Health’s National Library of Medicine (NLM), is the world’s largest database of biomedical literature. It provides citations, abstracts, and direct links to full-text articles via PubMed Central (PMC) or journal publishers. PubMed does not endorse specific conclusions — it connects researchers, clinicians, and the public to original, peer-reviewed science.
- MEDLINE: A carefully curated collection of journals indexed with MeSH® (Medical Subject Headings) for precise, high-quality searching.
- PubMed Central (PMC): A free full-text archive of biomedical and life sciences literature managed by the NLM.
- NCBI Bookshelf: A collection of peer-reviewed books, reports, and health guidelines.
Why Rigorous Journal Vetting Matters
Only journals that meet strict standards set by the NLM’s Literature Selection Technical Review Committee (LSTRC) are indexed in MEDLINE. This review evaluates editorial quality, peer-review processes, scientific methodology, and overall impact — helping ensure the evidence we rely on is trustworthy and clinically relevant.
How LifeSource Vitamins Uses Evidence Responsibly
- We prioritize human randomized controlled trials (RCTs), meta-analyses, and systematic reviews from high-quality, peer-reviewed journals.
- We apply MeSH terms and article-type filters to identify the strongest available evidence.
- We verify full-text articles in PMC whenever possible for complete transparency.
- We follow strict link verification protocols — including snapshots, PMID/PMCID tracking, and active 200-OK checks — to keep all references current.
- All claims are kept strictly within structure–function guidelines and accurately reflect the strength of the supporting evidence.
