GABA is the main inhibitory neurotransmitter, promoting calmness. Standard oral GABA poorly crosses the blood-brain barrier, limiting its central effects. Liposomal encapsulation is a delivery technology designed to protect GABA from degradation in the gut and enhance its absorption. While proponents claim this may improve delivery to the central nervous system, strong human evidence confirming this specific advantage is limited. Its primary healthspan relevance is through the indirect benefits of improved sleep and stress reduction.
Verdict
A potentially better-absorbed but unproven tool for sleep and relaxation.

Protocol
- Typical doses range from 100-250 mg taken 30-60 minutes before sleep or during periods of high stress.
Flags
- Efficacy is debated due to poor blood-brain barrier penetration, even with liposomal delivery.
- May cause drowsiness; avoid operating heavy machinery after use.
- Use with caution if taking other sedatives, anxiolytics, or blood pressure medications.
