What is GABA?
GABA is a neurotransmitter naturally found in the brain and even in some foods like tomatoes and soybeans. It's an inhibitory neurotransmitter that blocks chemical signals in the central nervous system and reduces brain activity. GABA can help promote calmness in the body and helps regulate nerve cell hyperactivity when feeling fearful, anxious or stressed.
It's sold without a prescription as a dietary supplement, but GABA's effects may also benefit those who struggle to fall asleep.
Taking GABA for sleep
Taken alone or with other natural sleep aids, GABA supplements help address anxiety, stress and an overactive brain, three main offenders that make it difficult to fall asleep. Its calming effect puts the mind in a relaxed state, so you're in the right headspace to drift off to sleep.
Low GABA levels have actually been linked to sleep deprivation, as one study found participants with insomnia had 30% lower levels of GABA in their systems. Another small-scale study by Frontiers in Neuroscience involving middle-aged adults found that taking 300 mg of GABA before bed for at least a week can reduce sleep latency (the amount of time it takes to fall asleep).
There's no solid research showing GABA helps sleep efficiency (quality of sleep and slow wave sleep), but the study's results showed it may promote sleepiness as it affects early sleep stages. Another benefit is that it won't leave you feeling drowsy the following morning like other over-the-counter medications such as ZzzQuil or prescription sleep medications.
