About ProHealthIt
ProHealthIt is a free health knowledge platform that pairs interactive calculators with comprehensive, evidence-based guides. We cover pregnancy, fitness, nutrition, body metrics, mental health, and medical conditions — each topic supported by peer-reviewed research and authoritative medical sources.
Our Mission
Most health calculator sites give you a number and leave. We give you the number, explain what it means, show you where it fits in the clinical context, and cite the exact research behind it. Every page is designed to make you more informed — not more anxious.
Who Makes This
Ash K
Founder & Lead Writer · Based in India
Ash researches, writes, and maintains all content on ProHealthIt. Every article is built from primary medical sources — published clinical guidelines, peer-reviewed studies, and data from WHO, NIH, ACOG, ADA, and CDC. Ash is not a medical professional. ProHealthIt is a health information resource, not a medical practice. All medical content reflects published guidelines and is clearly attributed to its source.
Editorial Process
Every piece of content on ProHealthIt follows a structured editorial process:
1. Research
Every article begins with a review of current clinical guidelines, peer-reviewed studies, and authoritative medical references (WHO, NIH, ACOG, ADA, PubMed).
2. Writing
Content is written by Ash K with a focus on accuracy, clarity, and practical usefulness. We avoid medical jargon where plain language works.
3. Fact-Check
Every factual claim is cross-referenced against at least two independent medical sources. Calculator formulas are verified against their original published papers.
4. Updates
Content is reviewed and updated when new guidelines are published or when clinical standards change. Every page shows its last update date.
Our Sources
We rely exclusively on authoritative, evidence-based sources:
- WHO — World Health Organization growth standards, BMI classifications, public health guidelines
- NIH — National Institutes of Health nutritional research, clinical trial data
- ACOG — American College of Obstetricians and Gynecologists pregnancy guidelines
- ADA — American Diabetes Association diagnostic criteria and standards of care
- PubMed — Peer-reviewed studies and meta-analyses from major medical journals
- CDC — Centers for Disease Control and Prevention growth charts, screening tools
Calculator Methodology
Every calculator on this site uses established, published formulas. We cite the exact equation and the original paper on every tool page. Our calculators use Mifflin-St Jeor for TDEE/BMR, IOM 2009 guidelines for pregnancy weight gain, CKD-EPI 2021 for kidney function, WHO growth standards for child development, PSS-10 for stress, GAD-7 for anxiety, and EPDS for postpartum depression screening.
All calculations run entirely in your browser. We never send your health data to our servers.

ProHealthIt is not a substitute for professional medical advice, diagnosis, or treatment. Our tools are educational and informational. Classifications and scores reflect published medical criteria (ADA, ACOG, DSM-5) and are not diagnoses. Mental health screening tools are not diagnostic instruments. Always consult your healthcare provider with questions about your health.
