Flavonoid Antioxidant Supplements

Browse a curated collection of flavonoid antioxidant supplements created to support everyday wellbeing routines in the United Kingdom. Flavonoids are naturally occurring plant compounds found in foods such as berries, citrus fruits, tea and brightly coloured vegetables. Many people choose supplements to help complement a balanced diet and a consistent wellness plan, especially during seasonal changes, busy work periods or training blocks.

Across this range you may find popular options like quercetin, citrus bioflavonoids and broader polyphenol blends. Some formulas are designed to pair well with core nutrients such as vitamin C and zinc, and can be used alongside common choices like magnesium, probiotics and omega-3 fish oil, depending on your goals and current intake. We prioritise clear labelling to help you compare active ingredients, serving sizes and format (capsules, tablets or powders) with confidence.
