Avoid or Delay Caffeine Use in Young People

Children age 14 and younger should avoid caffeine if possible. For adolescents roughly 15–18 or 20, limit caffeine as much as possible because brain wiring is still occurring. Energy drinks and added neuroactive ingredients such as theanine and L-tyrosine are best left until about age 18 or older. Young people should delay starting caffeine use for years if possible.
