Be careful listening to the social media gurus. They’re often just salesmen that overestimate their expertise.

“There has been a trend, mostly on social media, to recommend delaying coffee ingestion in the morning by anywhere from 30–60 minutes to as much as 90–120 minutes after waking.

The primary rationales are to prevent prolonging the waking cortisol peak because adenosine levels are still declining during this time, and/or to avoid an afternoon “crash” that some claim happens as caffeine is eliminated from the system.

However, the validity and utility of these claims are questionable at best and, in some cases, not supported at all based on the available scientific evidence”
