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!

I am getting pretty old, my daughter bought these for me as she is very health conscious. In light of the past years events she was worried about me and bought me these. I normally wouldn’t post a review but they have made me feel stronger and seem to have more energy throughout my day. Great product and will be buying again.
