What Are the Side Effects of Quicksilver Scientific GABA + L-Theanine?

Always consult your health practitioner if in doubt.

RiskLow Risk

Overview

GABA at 250mg and L-Theanine at 100mg per serving are within safe ranges established by clinical studies, with no serious adverse events reported up to 18g/day short-term for GABA and 900mg/day for L-Theanine.
Potential mild side effects include transient blood pressure lowering from GABA, so monitor if on antihypertensive medications; the liposomal formulation enhances bioavailability without added risks.
Not recommended for pregnant or breastfeeding individuals due to insufficient safety data on neurotransmitter and endocrine effects of GABA and limited research on L-Theanine in these populations.
No known allergens in the sunflower-derived phosphatidylcholine formulation, but sensitive individuals should check for sensitivities to ethanol or glycerin.
Long-term use beyond 12 weeks lacks extensive data; consult a healthcare provider for extended use, especially with CNS depressants to avoid enhanced sedation.
High-quality manufacturing by Quicksilver Scientific minimizes contamination risks, but as with all supplements, third-party testing is advisable.
