Inhibitory neurotransmitter, supports relaxation
We rank GABA by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
GABA is short for gamma-aminobutyric acid. It is an inhibitory neurotransmitter, which is a chemical messenger in the brain that tells nerve cells to slow down or stop firing.
It is primarily used to support relaxation. By mimicking the brain's natural calming chemicals, it is intended to help reduce feelings of stress and promote a sense of quiet in the mind.
To create the supplement, companies typically use a process called fermentation. This involves using specific bacteria to break down sugars or proteins into the GABA powder that is then put into capsules or tablets.
This ingredient is generally mid-range in price. This is because the fermentation process required to produce it is more complex than simple extraction, but it is still common enough that there is significant competition among manufacturers.
