Frequently Asked Questions
What is the difference between GABA and L-theanine?
GABA is a neurotransmitter that directly inhibits nerve signals, promoting relaxation and reducing anxiety. L-theanine is an amino acid that increases alpha brain waves, which are linked to a calm yet alert state. Together they complement each other for deeper stress relief.
Can I take GABA and L-theanine together safely?
Yes, many supplements combine them because they work through different pathways. The NUTRAHARMONY formula includes both in safe, effective doses. Always follow the recommended serving and consult a healthcare professional if you have concerns.
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.
