Resveratrol van Swanson

Deze capsules van Swanson leveren resveratrol, een plantenstof die van nature in onder andere rode wijn en druivenschillen zit. Elke capsule bevat 250 milligram. De resveratrol komt hier uit de wortel van de Japanse duizendknoop (Polygonum cuspidatum), de bron waaruit deze stof het makkelijkst te winnen is. Je neemt één capsule per dag, dus een pot van 30 gaat een maand mee.

Wat resveratrol is

Resveratrol hoort bij de polyfenolen, een grote groep stoffen die planten zelf aanmaken. Binnen die groep valt het onder de stilbenen. Je vindt resveratrol vooral in de schil van blauwe druiven, in rode wijn en in bepaalde wortels. Planten maken het aan als reactie op stress, bijvoorbeeld bij een schimmelaanval of veel UV-licht. Het is dus een stof die een plant produceert om zichzelf te beschermen. In supplementen wordt meestal de duizendknoopwortel gebruikt, simpelweg omdat daar veel resveratrol in zit.

Waarom Japanse duizendknoop als bron

De Japanse duizendknoop is de meest gebruikte bron voor resveratrol in supplementen. De wortel bevat er een relatief hoge hoeveelheid van, waardoor je geen liters wijn nodig hebt voor eenzelfde hoeveelheid. Eén glas rode wijn levert maar een fractie. Deze capsule bevat 250 milligram resveratrol uit die wortel, een vaste hoeveelheid die per capsule gelijk blijft. Zo weet je elke dag precies hoeveel je binnenkrijgt, zonder te hoeven schatten.

Hoe resveratrol in onderzoek wordt bekeken

Resveratrol is een veelbestudeerde plantenstof. Onderzoekers kijken onder meer naar hoe het inwerkt op sirtuïnes, een groep eiwitten die een rol speelt bij processen in je cellen. Wat veel mensen niet weten: de aandacht ging in eerste instantie vooral uit naar de stof in rode wijn. Daarna verschoof de focus naar geconcentreerde vormen zoals deze capsule. Door de EU-regels mogen we niet ingaan op wat resveratrol in je lichaam zou doen, maar de stof zelf is goed in kaart gebracht.

Trans-resveratrol en de Franse paradox

De belangstelling voor resveratrol begon bij de stof in rode wijn, een fenomeen dat weleens de Franse paradox wordt genoemd. Onderzoekers gingen de inhoudsstoffen van wijn bekijken en kwamen zo bij resveratrol terecht. Scheikundig bestaan er twee vormen: trans-resveratrol en cis-resveratrol. De trans-vorm is de variant waar verreweg het meeste onderzoek zich op richt. In supplementen uit duizendknoopwortel gaat het vooral om die trans-vorm. Omdat de wortel zoveel resveratrol bevat, levert een enkele capsule een hoeveelheid waar je anders een flink aantal glazen wijn voor zou drinken. En dan nog zonder de alcohol en suikers die in wijn zitten.

Resveratrol uit de duizendknoop is een geconcentreerde manier om deze veelbesproken plantenstof binnen te krijgen, zonder dat er wijn aan te pas komt. Swanson levert het in een eenvoudige capsule met 250 milligram per stuk.

Great Interactive Option
Color: Blue
To start, I have been very happy with this purchase. A couple of key points for me are durability and being able to keep my dog's attention. I have had it for almost a year, just a month shy, and she hasn't managed to get through the foam outer shell even though she tries real hard to do so. Let's just say, she's hard to find toys for because of her habit of finding the point of failure where she can pick and gnaw at until the toy is no longer safe for her to have. With this toy, she not only found her match, but it also has her watching, waiting, and even stalking. Only one small issue has recently occurred: the motor has started having an issue where the charge doesn't hold, and it doesn't remain on afterwards. I have reached out to Cheerble directly to see about replacing it since I am still within their 12-month timeframe, and they responded right away.

Quality product for the right dog...
Color: Orange
Honestly it's a really cool product well constructed and moves around on its own with several different modes. The design id brilliant with a tough rubber ball that unscrew to expose the element that makes it move in the middle. The dog won't be able to unscrew it but you can if you ever need to replace the ball for any reason but it would take some work for a dog to destroy the outer ball. Almost like "Kong" type material. The ball is about the size of a softball and the element inside is about the size of a golf ball. I thought my dog would love this but she was afraid of it, which is strange because she's afraid of nothing. Anyways I gave it to my neighbor upstairs and she has a yorkshire terrier who plays with it all the time so it all worked out great. Quality product . Good job!

Thought it was a good idea but not for my dog
Color: Blue
Seemed great but my dog continued to bark at it. Finally she hid it and I haven’t looked for it.

Durability
Color: Blue, Color: Blue
won’t give this product 1 star because my dog still had a good time with it for a few hours. After opening and preparing it, I gave it to my dog and it definitely caught his interest. However, when he chewed on it, plastic pieces started breaking off and he began swallowing them. This product is definitely not suitable for aggressive chewers.

Winner !!!
Color: Orange
This amazed us. For perspective, we're talking about a three year old white german shepherd who if he's in the mood, has and can kill a toy within minutes or oddly enough be gentle with furry balls and carry them around as if they are his babies. He's an odd duck. Anyway, since he was a pup, and to this day, he'll play and entertain himself, he'll grab a ball, throw it up in the air, then pounce on it as if it's from outer space. It's really quite cute and funny. Because of those two things I was looking for something interactive that would entertain him and confuse him....let's be honest, watching a confused dog is one of life's great pleasures. I tried two other interactive balls and they were crushed immediately. After reading a lot of reviews, people with german shepherds said this ball actually had a life span. I thought the third time could be the charm and ordered one. Well, I think it actually may be from outer space because he's obsessed with it and hasn't taken a bite out of it. He hasn't once chewed it or even teared little pieces off. The three settings are great. Sometimes he likes one better than another, then forgets about the others. I'll change it up to one he hasn't seen in a while and the whole game starts over again. He'll throw it up in the air as he does with his others, watch it and try to figure out which way it's going to go. And yes, he will pounce on it if he times it right. The size is perfect, it's heavier than your average ball but, that's what make it sturdy. I have to sneak it away when he isn't paying attention to charge it, otherwise he'll sit, stare and cry if he knows it's on the counter charging. It's a lot of fun for all of us. I'm so happy I bought it...... I say give this ball a chance even if you have a beast with killer instincts. I'm buying another for a friends 2 year old golden retriever granddog. Thank you Cheerble.
