Though better known as a sports supplement, L-Citrulline has a powerful neurological benefit. Once in the body, it increases levels of nitric oxide, which helps blood vessels relax and improves circulation. Better blood flow means better delivery of oxygen and nutrients to the brain, and better access for GABA and its supporting compounds.

In the context of Gabatrol Daily, citrulline plays an essential role: it improves the brain's uptake and response to GABA, helping this key neurotransmitter do its job more effectively. It’s the behind-the-scenes support player that ensures all the other ingredients work smarter, not harder.

 Sourced from herbs like rosemary and lemon balm, this powerful antioxidant plays a specific role in slowing the breakdown of GABA in the brain. It does this by inhibiting an enzyme called GABA-transaminase, which normally degrades GABA over time. By keeping GABA active longer, rosmarinic acid extends the calming effects of Phyto-GABA—so you can stay relaxed without constant re-dosing or tolerance risks. It also offers neuroprotective and mood-stabilizing effects, making it especially helpful in managing chronic stress and emotional burnout.

L-Theanine is an amino acid naturally found in green tea, that works by gently shifting brainwave patterns toward a more relaxed alpha state—often associated with creativity, clarity, and calm. But unlike sedatives or alcohol, theanine doesn’t knock you out. Instead, it promotes a smooth, focused calm—ideal for anyone juggling mental stress but still needing to function. It also boosts the effectiveness of GABA and supports the balance of dopamine and serotonin, making it a key ingredient for lifting mood and sharpening focus.
