Guidance is practical and specific to irregular hours, and coverage sets out what employee assistance programs and state provisions actually pay for before anyone urgently needs them.
The FDA cites 400 milligrams a day — about four to five eight-ounce cups of coffee — as an amount not generally associated with negative effects in healthy adults, with separate caution for pregnancy and adolescents.
