Coffee May Boost Your Mood And Brainpower, Even Without Caffeine

Researchers found that both caffeinated and decaffeinated coffee were linked to shifts in gut microbes and improvements in mood and behavior.

Caffeinated coffee showed extra benefits for anxiety, attention, and blood pressure compared with decaf.

The results suggest coffee’s effects go beyond caffeine alone and may work through the gut-brain axis.

The findings highlight a possible link between coffee, the microbiome, and brain health.
