Verwandle deinen Schlaf in nur 90 Tagen

1. Stunde

500 mg am Abend

Eine Kapsel am Abend, 500 mg reines L-Tryptophan. Die Aminosäure geht über den Darm ins Blut. Am besten mit etwas Abstand zur großen Eiweißmahlzeit, denn dort konkurriert sie mit vielen anderen Aminosäuren.

Nach 4 Stunden

Durch die Schranke ins Gehirn

Tryptophan braucht einen Transporter, um vom Blut ins Gehirn zu kommen. Dort ist es die natürliche Vorstufe von Serotonin, einem deiner wichtigsten Botenstoffe. Herstellen kann dein Körper die Aminosäure nicht selbst.

Am Ende des Tages

Aus Serotonin wird Melatonin

Wenn das Licht weniger wird, baut dein Körper aus Serotonin Melatonin, dein Schlafhormon. Am Anfang dieser Kette steht Tryptophan. Handy weg, Licht runter, eine Kapsel: Das ist das ganze Ritual.

7 Tage

Das Ritual steht

Sieben Abende, sieben Kapseln, immer zur gleichen Zeit. Dein Körper mag feste Zeiten, und die Kapsel wird zum Startsignal für den Abend. Kein Abmessen, kein Pulver, kein Aufwand.

14 Tage

Der Takt kommt zurück

Zwei Wochen gleicher Ablauf. Dein innerer Rhythmus richtet sich nach wiederkehrenden Signalen: Licht, Essenszeiten, das Zubettgehen. Die feste Abendroutine ist eines dieser Signale geworden, und der Abend findet seinen Takt.

30 bis 45 Tage

Ein Monat gleicher Abend

Nach einem Monat läuft der Abend nach Plan, und der Plan läuft ohne dich. 23 Uhr ist nicht mehr die Stunde, in der der Kopf erst richtig loslegt, sondern die, in der du das Licht ausmachst.

60 bis 90 Tage

Abschalten als Routine

Drei Monate Abendritual: Handy weg, Licht runter, eine Kapsel. Guter Schlaf ist keine Glückssache, sondern die Summe vieler kleiner Gewohnheiten. Eine davon passt bei dir in eine Hand.

What is L-tryptophan?

L-Tryptophan is an essential amino acid – which means the body cannot produce it itself and must obtain it through food. It is one of the eight essential amino acids that the human organism needs on a regular basis. Amino acids are the building blocks of proteins – without them, many bodily processes would not function.

Why is L-tryptophan particularly rare in the diet?

L-Tryptophan is the essential amino acid least represented in food. Compared to other amino acids, it occurs in significantly smaller amounts. This makes a conscious supply through the diet or targeted supplementation a topic that deserves more attention than most other amino acids.

Which foods contain L-tryptophan?

L-Tryptophan is found in small amounts in many foods: wholegrain bread, brown rice, lentils, wholegrain pasta, dark chocolate, dried figs, cheese and cocoa. Compared to other amino acids, however, the amounts are significantly lower – which is why tryptophan is one of the rarest of the essential amino acids in food.

Who is L-tryptophan interesting for?

L-Tryptophan is particularly interesting for vegans and vegetarians, since many tryptophan-rich foods are of animal origin. People with a one-sided diet or increased needs also often choose tryptophan. If you are pregnant, breastfeeding or taking medication, please consult your doctor before supplementing.
