Editorial Policy

Health and fitness information can affect how people live, so we hold our articles to a clear standard. This page explains how we make them. Please also read our medical disclaimer.

1. Where our topics come from

We write about strength training, nutrition and healthy aging. Our starting points are our own educational books and U.S. public-health guidelines. We then check every claim against independent sources rather than relying on the books alone.

2. Every health claim has a source we have checked

• We tie each health claim to a primary source — a peer-reviewed study, a systematic review, a clinical guideline or a public-health agency — and list our references at the end of each article.
• We confirm the citation details (authors, journal, year, identifiers) in public scientific databases.
• We read the study's abstract at a minimum, and its full text when it is freely available. We say in our internal notes which one we read.
• We check whether a paper has been retracted, and we flag preprints that have not been peer reviewed.
• We prefer systematic reviews, meta-analyses and guidelines to single studies, and we say when a finding comes from animals, cells or observational research.
• We do not use commercial, supplement-company or advertising pages as evidence for health claims.

3. We write what the evidence says — no more

We avoid promises, miracle claims and fear. If the evidence is limited, uncertain or mixed, we say so. If we cannot trace a popular statistic to a reliable source, we do not repeat it as fact.

4. How we use AI

We use AI tools to help with research, drafting and illustration. Every article is checked against its sources and approved by a person before it is published. Images created with AI are used to illustrate concepts and are identified as such.

5. Expert review

Articles about medical conditions, nutrition, supplements, pregnancy or other higher-risk topics should be reviewed by a qualified professional before publication. When an article has been reviewed, we name the reviewer and the date at the top of the article.

6. Updates and corrections

We review our articles when guidelines or evidence change and show the date of the last review. If we find an error, we correct it and note the correction. If you spot a mistake or an outdated statement, please email us at vitalmuscle.contact@gmail.com.

7. Independence

If we ever carry advertising, affiliate links or sponsored content, it will be clearly labeled, and it will not decide what our articles say.
