How Much GABA Should You Take for Insomnia?

GABA may be able to help you if you have insomnia, as it may be able to support the body’s natural sleep cycle. It may reduce sleep latency (how long it takes you to fall asleep) and improve sleep quality.

Some evidence has indicated that low GABA levels are associated with insomnia and shorter sleep duration. However, some studies suggest there is limited effect.

If you’d like to try this supplement for sleep, speak with your doctor to determine if it’s safe for you to try.

Clinical studies suggest that 120 mg of GABA per day for 12 weeks does not cause side effects. However, it’s a good idea to start low and increase the dose gradually as needed.

One study found that 75 mg was enough to help sleep-onset insomnia, and a lower dose may be preferable as there is less chance of side effects.

However, the effective dose may depend on age, the type of sleep issue, and the product form. And not everyone will experience benefits.

Always read the product label information and speak with your doctor before taking GABA.

It’s also important to note that not all supplements are created equally, and they are not regulated in the same way as medications.

Common side effects of GABA supplements can include:

• headache
• digestive upset
• drowsiness

Who Should Not Take GABA?

Speak with a healthcare professional before using supplements such as GABA, especially if you take medication or have existing health conditions.

Instances where you should avoid taking GABA include if you:

• are taking certain medications, such as benzodiazepines, antidepressants
• have kidney or liver disease

• have certain mental health conditions

In other cases, you may be able to take GABA, but it must be done under the recommendation and supervision of a healthcare professional.
