As the main inhibitory neurotransmitter in the brain, GABA’s role is to act like a “brake” and balance excessive stimulation.

Supplement Facts Show All 9 Show Less

L-Tryptophan

L-Tryptophan is an essential amino acid that is one of the required nutrients for natural serotonin synthesis.* The most common dietary sources of tryptophan include nuts and seeds, meats and dairy, fish and legumes.

Magnesium Glycinate

Glycine is an amino acid, attached to the magnesium molecule in magnesium glycinate. This is one of the highest-quality forms of magnesium available. We include magnesium glycinate because it helps support brain health and cognitive function.*

Rhodiola Rosea (root) extract

Used in traditional Chinese medicine for hundreds of years, this well-studied adaptogenic herb supports recovery and may reduce feelings of stress.*

Niacin

This formula contains niacin, a form of vitamin B3, because it’s crucial for the overall energy metabolism of the cell. Your cells need it to produce serotonin.*

Zinc Glycinate

Zinc glycinate is a critical factor in maintaining a healthy immune system, supporting optimal cell division and replication.* This innovative formula provides natural ingredients from vitamins, minerals, and amino acids that our bodies use as precursors and cofactors to support normal, healthy function of neurotransmitters.*

Gamma-Aminobutyric Acid

Gamma-Aminobutyric Acid is a naturally occurring neurotransmitter with central nervous system (CNS) inhibitory activity. Gamma-aminobutyric acid (GABA), converted from the principal excitatory neurotransmitter glutamate in the brain, plays a role in regulating neuronal excitability by binding to its receptors, GABA-A and GABA-B, and thereby causing ion channel opening, hyperpolarization and eventually inhibition of neurotransmission. GABA acts to slow down signals between neurons, making neurons less electrically excitable.

Grape Seed Extract

Similar to L-citrulline, grape seed extract is used to increase nitric oxide production to help GABA pass across the blood-brain barrier and enter the brain.*

L-Citrulline

An amino acid found in foods like watermelon, dairy, beef and pork. L-Citrulline is converted into L-arginine, a known nitric oxide booster, which is theorized to help shuttle GABA into the brain across the blood-brain barrier.

Rosemary Leaf Extract

Found in rosemary, sage, mint and basil, rosmarinic acid is a naturally occurring polyphenol flavonoid. It is also found in lemon balm and is used in aromatherapy to promote feelings of calm and relaxation.

What To Expect

"I wasn’t sure if this would work but I decided to give it a shot… and wow! It has made such a massive difference for me. My mood has improved so much, even just overall. I feel a lot happier and less stressed daily than I did before taking these. I’ve taken these now for about 2 months straight and I will never go without them again!"

- Corissa V.

"I haven’t felt this rested in years. I have several sleep issues, but most medications make me drowsy the next day. The GABA lets me sleep soundly and wake up feeling rested."

- Marion B.

"This is an amazing product. I was taking it for a while and then stopped. Immediately I felt my sleep pattern was off. I ordered it again and now feeling balanced throughout the day and my sleep pattern is getting better."

- Marina R.

    I have been taking serotonin, dopamine, and acetylcholine for a few month now, and can say that my mood had improved, stress reduced, I am calmer now, more focused and sleep better. Love those products!

    One of my favorite Supplements

    I've purchased GABA Brain from Natural Stacks several times, and it works really well for me. I usually take it at night to help me relax and sleep, and it definitely helps calm my mind.

    On especially stressful days, I'll take just one capsule during the day, and I've found that it helps slow my racing thoughts and gives me a greater sense of calm without making me feel overly tired. It helps me feel less stressed and better able to handle the day. It's become one of my favorite supplements for relaxation and stress support.
