According to the current ESIC bylaws, all energy drinks that are freely available on the market are approved for consumption by professional gamers.
When broadcasting eSports events, organizations and players often commit to intentionally not having any food, such as energy drinks, on camera.
All major eSports organizers cooperate with the ESports Integrity Commission (ESIC) standards. Here is the current list of prohibited substances issued by ESIC:
- Amphetamine sulfate (Evekeo)
- Dextroamphetamine (Adderall and Adderall XR)
- Dexedrine (ProCentra, Zenzedi)
- Dexmethylphenidate (Focalin and Focalin XR)
- Lisdexamfetamine (Vyvanse)
- Methylphenidate (Concerta, Daytrana, Metadate CD and Metadate ER, Methylin and Methylin ER, Ritalin, Ritalin SR, Ritalin LA, Quillivant XR)
- Modafinil and Armodafinil.
None of these substances is an ingredient of a regular energy drink, so drinking an energy drink is not a violation of the rules.
