Not medical advice

runstck is a supplement tracking and analysis tool. It is not a medical device, does not provide medical advice, and should not be used as a substitute for professional medical guidance. Always consult a healthcare professional before making changes to your supplement or medication routine.

Safety screening limitations

Our medication-aware safety screening flags are conservative awareness tools, not a comprehensive drug interaction database. Always review supplement changes with a clinician or pharmacist.

Wearable data

Trend analysis from wearable data shows correlations only, not causation. Changes in wearable metrics may be caused by many factors unrelated to supplements.

Your data

You own your data. You can export or delete it at any time. See our Privacy Policy for details.

Use of AI

runstck uses AI to parse supplement inputs and explain structured insights. AI outputs are bounded by rule-based facts and approved sources. AI does not diagnose, prescribe, or make unsupported health claims.
