What is GABA?

GABA, or Gamma-Aminobutyric Acid, is a naturally occurring neurotransmitter in the human brain. It is an inhibitory neurotransmitter, meaning it helps to reduce the activity of neurons, promoting relaxation and decreasing anxiety.

Where does GABA come from?

GABA is produced naturally in the brain from glutamate, an excitatory neurotransmitter, through the action of the enzyme glutamate decarboxylase. It can also be found in some fermented foods and teas, such as kimchi, miso, and pu-erh tea.

Interactions of GABA

Most nootropics are relatively safe to use on their own. Combining them with other substances may cause them to suddenly become dangerous or life-threatening.

GABA may interact with certain medications, such as benzodiazepines, barbiturates, and other sedative medications. If you are taking any prescription medications, it's important to consult with a healthcare professional before using GABA supplements.
