This tool gives general information based on the research summarised in Energy Drinks: What the Evidence Says About the Load You Are Taking. It is not a medical device, does not diagnose, and does not replace advice from your clinician.

Free vs Plus




Free (this page)
  • per-serving and per-day conversion
  • stacking and alcohol-mixing flags
  • text export and print
  • all citations and cautions


Plus (optional, one-time)
  • calendar (.ics) reminders
  • unlimited share images
  • share card without the 'Made with CortexLit' footer


Checkout isn't live yet, so Plus is unlocked here with a local code. The check runs in your browser and can be bypassed; it is a placeholder for a real payment link.






Free tier: 1 share image per result.






Commercial disclosure: optional paid Plus tier; all evidence, cautions and the main result are free. No affiliate links, no sponsors.

Limits: Labelled content is not always what is in the can: one product study found 84% of drinks matched their labels. This tool reads what you type from the panel and does not verify it.
