Frequently Asked Questions
What is the difference between GABA and L-theanine?

How long does it take for a GABA L-theanine supplement to work?
Most people notice a sense of calm within 30 to 60 minutes after taking the supplement. For ongoing anxiety or sleep issues, consistent daily use over a few weeks may provide more noticeable benefits. For a discussion on sleep-specific effects, refer to our article on GABA vs 5-HTP for sleep.
