Natural
Caffeine and L-Theanine
for Brain Fog
Combining caffeine (100–200mg) with L-theanine (200mg) to improve focus and mental clarity while minimising the jitteriness of caffeine alone.
How it works
L-theanine promotes alpha brain wave activity and reduces anxiety, while caffeine blocks adenosine receptors. Together they improve sustained attention and working memory without overstimulation.
What to watch for
Should not be used as a long-term fix for underlying fatigue. Avoid in the afternoon to prevent sleep disruption. Tolerance develops with daily use.
