Independent analysis of biomedical evidence
Biomedical research evidence-based.
Discover accessible, evidence-based research reviews on peptides, longevity, metabolism, skin biology, cognitive function, and sleep. We clearly separate human study results from animal, laboratory, and mechanistic studies.
Peer-reviewed sources
Links to publications where available.
Clear division of evidence
We distinguish between data from human studies, animal studies and laboratory research.
Included constraints
We clarify uncertainty and research gaps.
Regular servicing
We provide the publication and update dates.

Our process
How we evaluate biomedical evidence.
-
We are defining the question
We define the precise research question and appropriate search terminology.
-
We are finding evidence
We analyse peer-reviewed research, reviews and credible scientific sources.
-
We are categorising the types of evidence
We personally assess data from human, animal, in vitro and mechanistic studies.
-
We explain the limitations
We describe uncertainty, study limitations and unanswered questions.

Editorial standards
We clearly point out what research can — and cannot — show.
Transparency of sources
We provide links and identifiers where available.
Human data identification
Human results are not equated with animal studies.
Preclinical data labelling
We describe animal and in vitro study results in their proper context.
Without unsupported claims
The conclusions remain within the boundaries of the cited evidence.
Openness to feedback
We check for and correct significant errors in a transparent manner.
Visible inspection dates
The reader can see when the analysis was last updated.
Frequently asked questions
Frequently asked questions.
What is BioEvidenceHub?
An independent educational publication that explains biomedical research based on available sources.
How does BioEvidenceHub evaluate studies?
We are analysing study design, population, sample size, type of evidence, consistency of results and limitations.
Does BioEvidenceHub provide medical advice?
No. The service provides general educational information and does not replace personalised medical advice.
How do you distinguish between clinical and pre-clinical results?
Every type of evidence is clearly marked. Animal or in vitro results are not presented as confirmed effects in humans.
How are the sources selected?
We prefer peer-reviewed publications, systematic reviews, scientific databases and reliable institutions.
How often are reviews updated?
Materials are subject to periodic review, and the date of the last review is visible in the publication.
