What is Gaba?
Gaba is an amino acid naturally present in the human body, more specifically in the central nervous system. Its full name is gamma-aminobutyric acid, and it is often abbreviated to Gaba. This neurotransmitter plays an important role in regulating neuronal excitability and in managing stress and anxiety.
Gaba is also available as a dietary supplement, making it a popular choice for people looking to improve their mental and physical well-being.
The benefits of Gaba
1. Reduced stress and anxiety
Gaba is often referred to as the 'natural brain calmer' because of its role in regulating neuronal excitability and its calming effect on the nervous system. Studies have shown that taking Gaba supplements can help reduce stress and anxiety by increasing Gaba levels in the brain (1)(2).
2. Improved mood
Because of its calming effect on the brain, Gaba can also help to improve mood. Research has shown that it can act as a natural mood regulator by modulating the secretion of certain neurotransmitters involved in depression and anxiety, such as dopamine and serotonin (3).
3. Promotes quality sleep
Gaba plays an important role in regulating sleep and relaxation. Studies have shown that taking Gaba supplements can help improve sleep quality by promoting relaxation and reducing insomnia (4)(5).
4. Reducing chronic pain
Gaba may also have analgesic effects by acting on pain receptors in the brain. Studies have shown that taking Gaba supplements can help reduce pain in people suffering from chronic headaches, fibromyalgia and certain other painful conditions (6)(7).
Origin of Gaba
Gaba was discovered in 1950 by Japanese researchers who extracted this amino acid from green tea. It is also found in foods such as sunflower seeds, nuts, seafood and seaweed, although these sources are not as rich in Gaba as supplements.
The Gaba used in food supplements often comes from the fermentation of plant-based sugars such as rice or wheat. This fermentation process creates a form of Gaba that is more bio-available and easily absorbed by the body.
Uses of Gaba as a food supplement
Gaba is generally available in powder, capsule or tablet form. Because of its relaxing effect, it is often taken in the evening to improve sleep and promote relaxation. However, some people may also take it during the day to help reduce stress and anxiety.
The recommended dose of Gaba varies according to the objective sought and the sensitivity of each individual. It is best to start with a low dose and gradually increase until you find the effective dose for each individual. It is also advisable to consult a health professional before taking any supplement.
Factors to consider when using Gaba as a dietary supplement
1. Interaction with certain drugs
As with any supplement, it is important to consider possible interactions with other medications. Gaba can potentially interact with certain sedatives, antidepressants and blood pressure medications, so it's important to consult a healthcare professional before starting to take this supplement.
2. Possible side effects
Although Gaba is considered safe, some people may experience side effects such as nausea, headaches, dizziness or drowsiness. It is advisable to start with a low dose and increase gradually to minimise the risk of side effects.
3. Not recommended for pregnant or breast-feeding women.
Gaba supplements are not recommended for pregnant or breast-feeding women due to the lack of studies on the safety of its use during this period.
In a nutshell
Gaba is a naturally occurring amino acid that plays an important role in managing stress, anxiety and sleep. Available as a supplement, it can offer numerous health benefits, such as reducing stress, improving mood, promoting quality sleep and reducing chronic pain. However, it is recommended that you consult a healthcare professional before starting to take any dietary supplements containing Gaba.
