Plain-language health & nutrition reference
MedicationHow2 brings together two free reference guides: a medication orientation tool and an independently verified vitamin database — both built for quick, honest answers before you talk to a pharmacist, physician, or dietitian.
1,500+ medications
Drug names, general drug classes, and typical use cases — a starting point before a doctor's appointment or pharmacy conversation.
Browse medications →140+ vitamins & nutrients
An independently verified reference for vitamins, minerals, and essential nutrients — what they do and where to find them in food.
Browse vitamins →Two references, two different editorial standards
We believe in being upfront about how our content is made. The Medication Guide's database was built with AI assistance and has not been individually verified against an official pharmaceutical reference — read the Medical Disclaimer before relying on it. The Vitamin Guide's database is independently verified against recognized nutritional science and deliberately excludes pseudo-vitamins. Neither section is a substitute for professional medical advice.
