Our L-tryptophan capsules contain 100% pure L-tryptophan – an essential amino acid involved in the production of the "happy hormone" serotonin. Serotonin plays a key role in regulating mood, sleep, and emotional balance. The capsules are vegan, free from artificial additives, and laboratory-tested – ideal for naturally supporting relaxation and sleep quality.
What are L-tryptophan capsules good for?
L-tryptophan is the precursor to serotonin and melatonin. It supports mood elevation, promotes inner calm, and contributes to natural, restful sleep. The capsules are particularly recommended during times of stress, nervous tension, or sleep disorders.
When and how should you take L-tryptophan capsules?
It is recommended to take it with a large glass of water approximately 30 minutes before bedtime. This allows L-tryptophan to be optimally converted into serotonin and then into melatonin, making it easier to fall asleep. For maximum effect, combining it with B vitamins and magnesium may be beneficial.
