Proven Health Benefits of Quercetin

Quercetin is a highly potent antioxidant that is found in numerous different fruits and vegetables. While the term ‘superfood’ is very much an arbitrary distinction, one common feature that a lot of the most heralded foods do seem to share is quercetin. That’s because quercetin just so happens to be one of the most effective compounds around when it comes to heart health, endurance, weight loss, immune function and more.

The good news? Quercetin is actually one of the most abundant antioxidants in the human diet. This means you won’t need to spend money shelling out for expensive supplements or eating strange exotic foods – it’s found in a wide range of greens, tomatoes, berries and vegetables. This is especially true for the most deeply colored and nutrient dense varieties.

The Benefits

Like most antioxidants, quercetin will help fight free radicals and prevent them from breaking down cell walls. This can help to slow down the visible signs of ageing and also prevent damage to the nucleus that can lead to cancer-causing mutations.

What’s more though, is that quercetin is also anti-viral, anti-microbial and anti-inflammatory (1). In short, this makes it beneficial across the board and could be just the pick-me-up you need if you’re feeling worn down. Anti-inflammatory foods are thought to reduce heart disease, to improve blood pressure and to combat fatigue. It’s also thought to be antiallergenic as a natural antihistamine. This means it can be effective in reducing the effects of hay-fever and other allergies.

Quercetin, along with other flavonoids, is also effective at improving overall cardiovascular health by encouraging blood flow and reducing LDL cholesterol oxidation. Quercetin also helps to reduce some of the effects of stress, by suppressing the production of an enzyme that triggers cortisol release (2).


In short, quercetin is a highly beneficial ingredient in any diet. And seeing as it is highly abundant in a wide range of different foods, there’s no need to spend money on expensive supplements. Just eat a healthy, balanced diet with lots of fruit and veg and know that quercetin will be working its magic behind the scenes to keep you strong and well!
