Quercetin is a plant-based flavonoid (a type of antioxidant) found in various fruits, vegetables, and grains. It is particularly abundant in apples, onions, berries, citrus fruits, and leafy greens. Quercetin is renowned for its health benefits, especially its ability to support the immune system and overall well-being.
Quercetin combats free radicals in the body, reducing oxidative stress that can weaken immune cells. This helps protect the body from cellular damage and supports overall immune resilience.
Chronic inflammation can suppress the immune system. Quercetin also reduces inflammation by inhibiting the production of pro-inflammatory molecules, helping the immune system function optimally.
This powerful antioxidant has also been shown to inhibit the replication of certain viruses, including those causing colds and flu. It may reduce the severity and duration of respiratory infections.
Quercetin improves the activity of critical immune cells, such as macrophages and natural killer (NK) cells, which are essential for identifying and eliminating pathogens. Additionally, by stabilizing mast cells and reducing the release of histamine, quercetin helps manage allergic reactions and supports a balanced immune response.
Dietary sources include apples, onions (especially red), kale, broccoli, berries, and green tea in your meals.
It is also available in capsules (such as Immuni) or tablets, often combined with bromelain to enhance absorption.
Quercetin is a versatile, natural compound that strengthens the immune system by reducing inflammation, fighting viruses, and protecting cells from damage. Incorporating it into your diet or supplementation routine is an excellent way to boost immunity and overall health. Always consult a healthcare provider before starting any supplement.
