About ProHealthIt
ProHealthIt is a free health knowledge site that pairs in-depth, evidence-based articles with interactive tools. We cover pregnancy, fitness, nutrition, body metrics, mental health, and medical conditions — each topic explained by expert-level guides with citations from WHO, NIH, ACOG, and peer-reviewed research.
Every calculator on this site uses established, published formulas — Mifflin-St Jeor for TDEE, IOM 2009 guidelines for pregnancy weight gain, CKD-EPI 2021 for kidney function, PSS-10 for stress, GAD-7 for anxiety, and more. We cite the exact equation and original paper on every page.
Our Methodology
Articles pull information exclusively from authoritative sources: WHO, NIH, ACOG, Mayo Clinic, and PubMed studies. Every key claim is cross-referenced against at least two major medical references. We do not publish unsubstantiated health claims.
What We Are Not
ProHealthIt is not a substitute for professional medical advice, diagnosis, or treatment. Our tools are educational and informational. Always consult your healthcare provider with questions about your health.
