My Hydration Lab is an informational website. Nothing on this site is medical advice. Please read this disclaimer carefully before using our calculators, tools, or guides.
Not medical advice
All content on this website — including calculator results, guides, and articles — is provided for general information only. It is not a substitute for professional medical advice, diagnosis, or treatment. We are not medical professionals, and our tools do not create a doctor–patient relationship.
Estimates, not prescriptions
Our calculators use simplified formulas to produce estimates of daily water and caffeine intake. Individual needs vary widely based on health conditions, medications, pregnancy, breastfeeding, age, body composition, diet, activity, and climate. Treat every result as a starting point for your own judgment — not as a medical recommendation.
When to talk to a professional
- If you have a kidney, heart, or liver condition, or any condition that affects fluid balance.
- If you take medication that affects hydration (for example, diuretics).
- If you are pregnant, breastfeeding, or caring for an infant or a seriously ill person.
- If you experience symptoms such as dizziness, confusion, rapid heartbeat, fainting, or severe dehydration.
In an emergency, call your local emergency number immediately — do not rely on this website.
