Also known as Gamma-aminobutyric acidYour brain's brake pedal, sold in a form that may not reach it.
This is the same problem NAD+ has. The molecule matters enormously inside you, and swallowing it is not obviously how you get more of it where it counts — GABA crosses the blood-brain barrier poorly. There is some evidence for effects via the gut, and there is a lot of marketing that skips the question entirely. We publish the dose and leave the argument visible.
The main calming neurotransmitter in your nervous system, sold as a supplement.
Inside the brain it is the primary inhibitory transmitter. Oral GABA's route is likely indirect, through gut receptors, if it works at all.
In the brain, it dampens signalling. Whether a capsule of it gets there is the open question.
Someone taking it as part of a blend rather than expecting it to carry the night.
100 mg with a nightly formula.
Little to nothing you can identify.
Grade C. No approved claim. The blood-brain barrier question is unresolved and honest suppliers say so.
