Ich litt über Jahre unter Angst und Schlaflosigkeit seit ich mich mit den Wechseljahren herumschlage. Ich habe eine ganze Wagenladung von Produkten probiert und sogar daran gedacht, eine Hormonersatztherapie zu machen. Ich habe herausgefunden, dass für mich 5htp tatsächlich wirkt, und im vergangenen Jahr war Angst und Schlaflosigkeit in meinem Leben kein Thema mehr.
Leah –
Ho sofferto per anni di ansia e insonnia dall’inizio della menopausa. Ho provato un sacco di prodotti e ho persino pensato di seguire una terapia ormonale sostitutiva. L’unica cosa che ho trovato che funziona realmente è 5htp, e da un anno ansia e insonnia non disturbano più la mia vita.

Aiuta a mantenere a bada le voglie improvvise di cibo di metà pomeriggio, e rende più facile dormire bene.

Hilft, von den Nachmittagsknabbereien wegzukommen, und verhilft mir leichter zu einem guten Schlaf.
DaisyDee –
Avevo forti sintomi di sindrome premestruale che hanno portato a sbalzi di umore con irritabilità, stanchezza e rabbia. Il mio dottore mi aveva prescritto antidepressivi, ma dopo averli presi per un paio di mesi non mi piaceva l’idea di esserne dipendente. Ho fatto qualche ricerca e ho provato 5 HTP dato che le recensioni sembravano positive. Ne prendo 200mg al giorno, e la differenza è come il giorno e la notte, ho ancora i crampi, ma il mio umore non è più un problema.
DaisyDee –
Ich habe starke postmenstruale Symptome verspürt, die zu starker Reizbarkeit, Müdigkeit und geradezu zu Wut geführt haben. Mein Arzt verschrieb mir Antidepressiva, aber nachdem ich die ein paar Monate lang genommen habe, hat mir die Idee nicht gefallen, davon abhängig zu sein. Ich habe ein wenig nachgeforscht und habe 5 HTP versucht, da die Kritiken positiv aussahen. Ich nehme 200 mg am Tag, und der Unterschied ist wie Tag und Nacht. Ich bekomme immer noch Krämpfe, aber meine Stimmung verändert sich nicht mehr auf die gleiche Weise.
Nickster –
