About VitalMetricHub

VitalMetricHub publishes free, mobile-friendly calculators for common wellness questions. Our formulas are drawn from widely cited clinical and public-health references—such as WHO/CDC guidance for BMI, the Mifflin–St Jeor equation for energy needs, and established anthropometric methods where applicable.

Our calculators are based on peer-reviewed research and mainstream clinical references, interpreted for educational use. They are maintained as general tools, not personalized medical care.

Nothing on this site replaces individualized advice from a licensed clinician, registered dietitian, or obstetric provider. See our Medical Disclaimer and Terms for limitations.

We aim to review calculator copy and references on a regular cadence (see the “last updated” line on tool pages). Dates reflect editorial updates, not individualized medical review of your situation.

VitalMetricHub does not offer one-to-one medical review, telehealth, or prescriptions. “Medically reviewed” labels on pages indicate that content is written for general education and checked against standard references—not that a clinician has evaluated you personally.

If you spot an error in a formula description or a broken citation, please contact us via the Contact page so we can correct it.
