The more detailed description of ingredients is presented below.
GABA, 633 mg
GABA is a neurotransmitter that regulates many of the depressive and sedative actions in brain tissue, and is critical for relaxation. 
Its role is to act as a break in our brain and is therefore also very important for a peaceful mind, good sleep, and calm thoughts.
L-Citrulline, 500 mg
L-Citrulline is an amino acid that can be found in food like watermelon, dairy products, beef, and also pork. It is converted into L-arginine, which has to do with shuttling GABA into the brain across the blood-brain barrier. 
Rosemary extract contains more than two dozen antioxidants. it provides effects such as protecting brain cells from the typical effects of aging, helps reducing hypertension, and among other things, increases the potency of vitamin E. 
It is also often used in aromatherapy to promote feelings of calm and relaxation.
A grape seed extract has similar effects as L-citrulline. It helps GABA with passing across the blood-brain barrier and enter the brain.
GABA Brain Food Dosage
The suggested dosage is 1-3 capsules per day. The best timing is in the evening to support calmness or during stressful or anxious situations.
I started and continued with taking 2 capsules a few hours before sleep in my test period.
I suggest you start with 1 capsule per day and see how it works.
However, it is vital to keep in mind that you don’t exceed 3 capsules per day.
Also, it is very welcome that you talk to your doctor before you start taking it.
GABA Brain Food Reviews
The brand Natural Stacks that developed GABA Brain Food supplement has a global reputation and is also well-known for its quality products.
Here are some reviews from people who used GABA Brain Food.
“Excited to finally have my supplements and experiencing how they affect my mood and behaviour. I have tested them out in several situations, from stressing work to workout and in times of personal challenges. I wish to continue my dosage of supplements from Natural Stacks as long as I can – they’re just great.”
“I was in search of a natural supplement to help with anxiety and trouble sleeping. After some research on Natural Stacks GABA I decided I would try it. It has helped a good bit. I have been taking one each night before bed and I am able to fall asleep and have went from getting up during the night at least 4 times a night to once a night. Would definitely recommend.”
“Subjectively GABA gives me better sleep. Objectively (tracked by Oura ring) I can see I get more full sleep cycles per night – prior taking this supplement I used to have very little REM. It’s so consistent that just from looking at my sleep graph I can tell when I took it, and when not. I also noticed that if I take it right before sleep I only get REM in the morning, but if I do it 1-2 hours before going to sleep it’s spread better through the night. It works well for me and I will buy it again.”
