90 capsules, a three month supply at the recommended dose of one capsule per day.

Studies on oral GABA supplementation have found real associations with relaxation and reduced stress markers, and the effects themselves are reasonably well documented in research. What scientists are still working out is the precise mechanism behind them. The traditional view was that the blood-brain barrier blocked GABA from entering the brain directly, but more recent research points to other plausible routes: GABA receptors in the gut, signalling through the gut-brain axis, and emerging evidence suggesting the barrier may be more permeable than previously thought. The research shows something is happening. The science on exactly how is still catching up.

L-theanine is an amino acid found almost exclusively in tea. It has been studied for its interactions with GABA and glutamate receptors in the nervous system, and its influence on alpha brain wave activity. It does not cause sedation. At 133mg per capsule, it is included within the dose range used in research and is the best-studied ingredient in the formula from a mechanistic standpoint.

Pyridoxal-5-phosphate (the active form of B6) is a required cofactor for glutamate decarboxylase, the enzyme that synthesises GABA from glutamate in the brain. Its inclusion is a specific formulation decision rooted in GABA biochemistry, not a generic addition. It also carries the formula's regulatory claim: Vitamin B6 contributes to the normal functioning of the nervous system.

No. Sleep Well does not contain melatonin. The formula is built around GABA, L-theanine and Vitamin B6 as P5P. Melatonin has variable regulatory status across EU markets and is absent from this formula by design.

For adults only. Not suitable for children, or during pregnancy or breastfeeding. If you are taking medication — particularly sedatives, anxiolytics, or other compounds affecting the nervous system — seek medical advice before use. Do not exceed the recommended daily dose.
