GABA stands for gamma-aminobutyric acid, a naturally produced neurotransmitter in the brain. It helps to inhibit the nerve cells or in other words, it has a calming effect that makes you less anxious when present at a healthy level in your brain. (1)

Health Benefits of GABA

This naturally produced neurotransmitter can have significant effects on both your body and mind in various ways. Here are some of the benefits you may experience from increasing the GABA level in your body with supplements.

  • GABA Helps With Anxiety – The lack of GABA has been linked to various forms of disorders like anxiety, depression and excessive stress.  An in-depth study has also pointed to the importance of GABA in preventing overstimulation of the nerve cells and thus, preventing anxiety.

  • GABA Helps With Depression – While it isn’t conclusive that lack of GABA causes depression, researchers have found the people suffering from depression do have a low level of GABA. Those who have overcome depression also displayed an increase in GABA, thus suggesting that GABA is a great remedy to treat depression.
  • GABA Prevent Inflammatory Diseases – Inflammatory diseases like cardiovascular diseases, cancer and arthritis linked to chronic inflammation as the immune system reacts to protect our body. Early studies have linked GABA to reducing inflammation, thus reducing the risk of the associated diseases.
  • GABA May Increase Growth Hormone – Both adults and children require growth hormone to function optimally. It is important to ensure the proper growth of children and promote heart health, muscle and bone strength in adults. A study conducted at Shenandoah University has shown that the level of growth hormone increases when GABA is taken orally.

How To Take GABA Safely

For GABA to be effective, it needs to cross the blood-brain barrier, a natural protective mechanism that prevents harmful agents from entering our brain, and subsequently, good compounds as well. Studies that are conducted suggests that a small portion of GABA taken orally will enter the brain.

However, more accurate research remains elusive as it is very difficult to measure the presence of GABA in the human’s brain. Due to this, health experts could not recommend a standard dosage that is applicable to every consumer.

The suggested dosage of GABA is 250 mg per day if you’re taking it for sustaining your mental health. For more critical needs such as reducing anxiety or depression, some manufacturers recommended up to 1000 mg of GABA per day. (2)

If you’re in doubt of the right dosage, always consult your physicians.

Precautions And Side Effects Of GABA

GABA is a naturally synthesized and has very mild effects when consumed. You may find yourself experiencing side effects like drowsiness or gastric sensations when taking GABA. (3)

While GABA is considered generally safe, it is advised that you’re starting from a low dosage and gradually increase it to larger doses. If you’re in doubt of the right dosage, always talk to your doctors before taking GABA.

There is limited research on the effects of taking GABA supplement for pregnant or breastfeeding moms. Therefore, it is advisable to avoid taking GABA if you belong to either of the categories.

GABA supplements should only be taken by children above 12 years of age. While children with ADHD may benefit from taking GABA, you should always consult your doctors for the right dosage.

How Effective Is GABA

Some supplements required consistent consumption for a number of days before you could start to feel the changes. But not GABA. You may find GABA start inducing relaxation and sleep after 30 minutes or so after taking it. That’s roughly the time it takes for GABA to enter your bloodstream and starts affecting your body positively.

Again, this can vary between individuals as there are no studies that confirm this.
