But is it good for everyone?
There is an association between caffeine ingestion and mental health.
In fact, the Diagnostic and Statistical Manual of Mental Disorders (DSM–5) — the guide published by the American Psychiatric Association and used by healthcare professionals for the diagnosis of mental disorders — currently lists four caffeine-related disorders:

- caffeine withdrawal
- unspecified caffeine-related disorder
- other caffeine-induced disorders (anxiety disorder, sleep disorder)
