Quercetin (lat. quercus = Eiche) gehört zu den natürlichen gelben Pflanzenfarbstoffen aus der Gruppe der Polyphenole und Flavonoide. Es entsteht in der Natur mit Hilfe einer Oxidationsreaktion aus einem Anthocyanin-Farbstoff. Quercetin spielt in Pflanzenzellen eine wichtige Rolle beim Schutz vor oxidativem Stress und vor Schädlingen und Krankheitserregern. Zudem sorgen Flavonoide für einen effektiven UV-Schutz von Pflanzenzellen. Dies kann in der Natur beobachtet werden, wenn Pflanzen unter direkter Sonneneinstrahlung wachsen. Hier erscheint die Pflanze oft rot bis rötlich unterlaufen, was auf eine vermehrte Konzentration von Flavonoiden zurückzuführen ist. Aktuell gibt es viele Forschungsgruppen, die sich mit der Wirkung von Quercetin auf menschliche Zellen beschäftigen.
 
Wo finden wir Quercetin in unseren Nahrungsmitteln? Es ist in hohen Mengen in Zwiebeln, Kapern, wilden Heidelbeeren und Preiselbeeren, Schnittlauch und in roten Weintrauben enthalten. Somit enthält Wein, allen voran Rotwein, Quercetin. Dessen Gehalt wird durch eine Lagerung in Eichenfässern noch verstärkt. Es konnte festgestellt werden, dass sich die Hauptkonzentration an Flavonoiden in der Schale befindet. Große Mengen an Quercetin werden bei der Verarbeitung allerdings wieder zerstört.
 
Eine besonders hohe Konzentration an Quercetin wurde in den Blüten des Japanischen Schnurbaumes (Sophora japonica) nachgewiesen, woraus wir bei NatuGena unser Quercetin gewinnen. Es wird mittels schonender Wasser-Ethanol-Extraktion gewonnen. In der Rezeptur „Quercetin + C“ erhalten Sie einen standardisierten Quercetin-Gehalt angereichert mit Vitamin C und Lecithin, welches die Aufnahme in die Zellen verbessert. So ergibt sich Quercetin mit höchster Bioverfügbarkeit durch liposomale Formulierung.

Definitely worth the price
Size: 6.5, Color: Black/Black
Absolutely love these boots! I originally bought them to wear in NYC in December & they did not disappoint. They were comfortable, cute, durable and worked well in the slush/snow. The traction on the bottom is also nice! They kept me warm with wool socks. I wear them almost daily now. Perfect for everyday. easy to wear with variety of outfits. Good every day shoe.

Snagged a deal
Size: 7, Color: Redwood/Gum 10
I waited and waited to get these boots! I knew I was chancing it, but they went on sale, and I snagged them! I am a size 7, and they fit nicely with socks. a little loose, barefooted, but what psycho wears boots without socks? They are comfortable and really well-made.

Cute, comfortable waterproof boots (a little snug to put on)
Size: 7, Color: Velvet Tan/Gum 2
These are really cute Chelsea-style boots and feel very comfortable once they’re on. The waterproof material is great for wet weather and the sole feels sturdy with good traction. They look stylish enough to wear casually but still feel practical for rainy days. The only downside is they can be a little difficult to put on at first because the opening is somewhat snug, but once they’re on they fit well and feel supportive. Overall they’re a great waterproof boot and I’ve enjoyed wearing them.

Surprisingly great for my wide feet and high instep!
Size: 10.5, Color: Velvet Tan/Gum 2
So thrilled I took a chance on these. Finding boots is impossible for me. I have wide feet, a super high instep, a bunion on one foot, and I wear a hard to find size (10.5). I ordered the 10.5 and 11 in these expecting I might need to size up for width (if I could even get them on). It was a struggle getting the 10.5s on the first time, and once I did they were somewhat uncomfortable on the top of my left foot. But I read that they would relax so decided to give it a go because I need waterproof boots for an upcoming trip and the 11s felt too long. After two days of light wear, they are already breaking in and I have no more discomfort. Getting them on is already easier and they are plenty wide enough and very comfortable to walk in. These are true to size. Super happy and worth a day of mild discomfort to break them in!

Comfortable, sturdy, waterproof
Size: 9.5, Color: Black/Black
Loce, love, love these boots. Have walked ten miles with no foot pain around NYC. They go with everything and and are so comfortable. As they are waterproof/resistant, they get a little warm in high temps, but perfect three-season boots.
