Maca

  • Maca (Lepidium meyenii, peruvianum, Wurzel) stammt aus den Höhenlagen der peruanischen Anden. Es ist ein Knollengewächs und gehört zur Familie der Kreuzblütler (Brassicaceae). Auch wegen ihrer Wirkung auf den Energiehaushalt, Ausdauer, Libido und Vitalität ist die Maca-Pflanze ebenfalls unter dem Namen ‘Peruanischer Ginseng’ oder ‘Ginseng der Anden’ bekannt. Die Maca ist die einzige essbare Pflanze, die unter derart extremen klimatischen Bedingungen und in einer Höhe zwischen 3000 und 4000 Metern überleben kann. Die Wurzel der Pflanze ist sehr nahrhaft und wird seit Tausenden von Jahren von der lokalen Bevölkerung bei fast jeder Mahlzeit verwendet.
  • Macamide, Macaene und andere Wirkstoffe
  • Peri- und postmenopausale Beschwerden
  • Wegen des Einflusses von Maca auf den Geschlechtshormonstoffwechsel ist Vorsicht bei Männern mit erhöhtem PSA-Wert (Prostataspezifisches Antigen) und bei Frauen mit hormonempfindlichem Brustkrebs angebracht. Es ist wenig über die Sicherheit der Verwendung von Maca während Schwangerschaft und Stillzeit bekannt.
  • Von Maca sind keine nennenswerten Nebenwirkungen bekannt. In den Anden werden etwa 50-100 Gramm Maca-Knolle täglich ohne Nebenwirkungen konsumiert. 
  • Wie alle Pflanzen aus der Familie Brassicaceae enthält Maca relativ viel Vitamin K. Aus diesem Grund sollten Patienten, die Blutverdünner verwenden (Antikoagulantien wie Warfarin) vorsichtig sein mit der Einnahme von Maca, weil eine hohe Einnahme von Vitamin K der Wirkung von Blutverdünnern entgegenwirkt.
  • Die empfohlene Dosierung für gesunde Erwachsene beträgt 1500 bis 3000 mg pulverisierte Maca-Knolle pro Tag. Als Extrakt ist eine (viel) niedrigere Dosierung (ein paar hundert Milligramm) ausreichend, abhängig vom Konzentrationsgrad des Extrakts. Für eine stabile, therapeutische Wirkung ist es ratsam, einen standardisierten Extrakt zu wählen, vorzugsweise auf beta-Sitosterol oder andere Sterole standardisiert.
