GABA, or gamma-aminobutyric acid, is a neurotransmitter naturally present in the human brain, playing a fundamental role in regulating neuronal activity as the central nervous system’s main inhibitory messenger; when GABA levels are sufficient, the brain finds it easier to slow its activity, supporting a state of inner calm conducive to relaxation and falling asleep.

Lacto-fermented GABA, known as LF-GABA, is produced through a natural bacterial fermentation process; unlike chemically synthesised GABA, lacto-fermented GABA comes from a biological process that mimics the natural mechanisms behind this amino acid, offering high purity, better digestive tolerance than its synthetic equivalent, and a naturalness that matches consumers’ expectations for quality supplements. This formula provides 150 mg of lacto-fermented GABA per capsule, or 300 mg for the recommended daily dose of two capsules.

Vitamin B8, also known as biotin, is an essential nutrient involved in many metabolic functions; each capsule provides 25 micrograms of vitamin B8 (50% NRV), reaching 50 micrograms (100% NRV) for the two-capsule dose. Biotin contributes to normal nervous system function and energy metabolism, supports normal psychological function, and is also known for its role in maintaining normal hair, skin and mucous membranes.

Modern life brings many sources of tension — a demanding work pace, information overload, little time to recover — that can disrupt neurotransmitter balance and affect sleep quality and the ability to relax; GABA is one of the most studied nutrients in the context of stress management and natural relaxation, and is also popular with athletes, as it’s involved in night-time recovery processes linked to the natural release of growth hormone during deep sleep.

Take 1-2 capsules a day, ideally in the evening, around 30 minutes before bed, with a large glass of water; keeping to regular times supports a beneficial sleep routine. A 60-capsule box provides a one-month course at two capsules a day, or two months at one capsule a day, allowing intake to be tailored to individual needs.

Store in a cool, dry place, away from direct light and humidity. Do not exceed the recommended daily dose. Not recommended for pregnant or breastfeeding women without medical advice. Keep out of reach of young children. A food supplement is not a substitute for a varied, balanced diet and a healthy lifestyle.

Is lacto-fermented GABA different from classic GABA?

Yes. Lacto-fermented GABA (LF-GABA) is obtained through a natural bacterial fermentation process, while classic GABA is usually chemically synthesised. The lacto-fermented form is known for better tolerance and a more natural production process, closer to the body’s own biological mechanisms.

How long before I feel the effects of GABA?

Effects on relaxation can be felt within the first few days of use. For more established benefits on sleep quality, regular use over several weeks is generally recommended; everyone responds differently, and results vary from person to person.

Can GABA be combined with other supplements?

GABA is often paired with magnesium, glycine or L-theanine in relaxation and sleep protocols. We recommend seeking advice from a professional to find the combinations best suited to your situation; our team at Herba Barona in Paris is happy to help.
