    Fight Back Against Free Radicals

    Quercetin is a well-studied plant pigment (bioflavonoid) found in plants and foods, such as red wine, onions, green tea, apples & berries.

    It is one of the most abundant antioxidants found in food that can play a role in supporting your immune system & protecting your cells from oxidative stress caused by harmful free radicals.

    It's often paired with bromelain (a natural enzyme found in pineapples) because both offer natural anti-inflammatory effects & work together in partnership.

      Amazing re

      Following a fall on my face I’ve suffered from chronic maxillo sinusitis for a year, trying many sprays to gain relief. I also suffer from hay fever which is very troublesome this year.

      I read that these capsules help sinusitis, so decided to try them and have taken 2 daily for only a week.

      I’ve just realised my breathing is clear and I’ve not been using tissues all the time. It can only be Quercetin (which I’d never heard of) that has brought this transformation. I feel more energetic and less stressed

      - so they are worth every penny!

      Highly recommend

      Ive been looking for a good quality, no nasty fillers supplement. I have been sick with Long Covid for a few years and have increased all my supplements and started using purolabs. I am starting to see a turnaround in my health so am more than happy with the results. This particular supplement is great for covid as it helps with inflammation and also histamine intolerance which has become a main symptom in Long covid.
