Are you looking for a natural way to strengthen, revitalise and boost your body from within? Quercetin is a natural flavonoid that the human body does not produce itself, but is found in a lot of colourful plants and foods.

Quercetin has been one of the most extensively scientifically researched flavonoids for its ability to combat oxidative stress and bolster the bodies’ natural defences. While the world is looking for natural solutions to increase bodily function and resistance, Quercetin is the supplement world’s worst kept secret!

What is Quercetin?

Quercetin is a powerful and colourful flavonoid that is found primarily in things such as:

  • Fruits
  • Vegetables
  • Plants
  • Roots
  • Wine
  • Tea

Quercetin is simply a plant pigment which is found in a multitude of plants and helps plants protect themselves against bacteria, fungus, UV rays and viruses. As great as that is, I am sure you are wondering, how does that help me?

What is WeightWorld Quercetin?

Quercetin contributes to defences against oxidative stress, but what does this mean? Oxidative stress has been linked to many degenerative conditions as well as ageing and can be very harmful to our bodies. A simple google search will tell you how severe oxidative stress can be! Although Quercetin can be found in foods that we eat, a lot of the time we do not have the time or resources to keep up that lifestyle. That is where we come in. We have developed our Quercetin capsules with a high potency 500mg dose so that you can quickly and conveniently compensate for what you have lost through your diet. Although oxidative stress is the main concern, Quercetin can actually benefit you in many other ways from aiding in the effects of ageing to contributing towards your weight management goals!

Who can take Quercetin?

Although anyone can do with a daily boost to their bodies, Quercetin is actually a popular supplement for athletes and gym goers! This is because people are turning towards natural supplements to give their body the protection and energy it needs to take on intensive tasks. We have created our capsules for everyday people to both fortify their bodily resistances as well as contribute towards their dieting plans. We want to make looking after yourself easy and stress-free, so for anyone looking to repair, rejuvenate and refresh their bodies, we have created this product for you!

Vivement qu’ils vendent des boites pour 1 an, ça nous évitera d’en acheter tous les 6 mois. Sinon rien à dire sur le produit en lui-même.
