Quercetin is a naturally occurring flavonoid compound that is present in many fruits and vegetables, including cranberries, kale and even onions. While you can very well rely on these foods to get your quota of quercetin, you will be hard pressed to get enough of this compound to really experience its majestic benefits.
Quercetin boasts several benefits, some of which may contribute to improved immune function over the long haul. Most notably, it is sought after for the following benefits:
Mitigates Allergy Symptoms
Many people suffer from seasonal and year-round allergies, independent of any other type of condition. Quercetin can help you deal with the constant sneezing and congestion that is characteristic of allergies by blocking histamine and other mediators of inflammation.
Inflammation triggers a cascade of other chemical reactions in the body that may resemble a cold/flu, so it makes sense to keep your allergies in check, especially during trying times.
May Enhance Immune Health
Studies conducted involving quercetin’s effect on the immune system have appeared promising to date, such as the one which revealed that daily consumption of 1000mg of quercetin may help to reduce the number of sick days and severity of symptoms experienced in over 1000 people aged 40 and older[i].
This is noteworthy since it is believed that older people are more susceptible to the cold and flu. It was also found to reduce the incidence of respiratory tract infections in trained endurance athletes[ii], and at a low dose of only 100mg daily.
Reduces Oxidative Stress
Oxidative stress is the spark that ignites the fire which damages many cell types within the body, the immune system not exempted. Free radical damage can suppress immune system function by reducing its capacity, or owing to the chronic inflammation that ensues, makes it less efficient at dealing with real threats (such as is common in auto-immune disorders).
Quercetin may block prostaglandins[iii] and cytokines[iv], both important mediators of the oxidative-inflammatory response of the immune system.
