There are many health benefits of quercetin. Its anti-inflammatory and antioxidant properties may help prevent cardiovascular diseases and improve arterial walls. Other possible side effects include an increase in energy levels and athletic performance. If you are considering taking this supplement, it is essential to know the risks and benefits.


Quercetin is a phytonutrient that has several anti-inflammatory effects. It inhibits the production of IL-18, ASC oligomerization, and the activity of the NLRP3 inflammasome. It also reduces ROS production.

Anti-prostate cancer

Recent research has shown quercetin to have some promising anti-cancer properties. Currently, it is used in the treatment of prostate cancer. It has been shown to reduce the side effects associated with conventional therapies. More studies are being conducted to explore the role of quercetin in cancer prevention.

Improves athletic performance

Quercetin, a compound found in berries, has been shown to improve athletic performance in a small number of studies. The effect, however, is small compared to caffeine and other performance enhancers. Nonetheless, quercetin has a lot of promise. It can increase your body’s ability to absorb oxygen, improving athletic performance.

Increases energy levels

Quercetin has been shown to increase energy levels in humans. It increases the metabolic rate, increases the rate of energy expenditure, and decreases body fat. These effects have been noted in both humans and mice. These effects may have several different mechanisms.

Causes allergic rhinitis

Quercetin is a powerful antioxidant that fights off allergic rhinitis. It blocks the overactivation of mast cells, which secrete histamine, the primary cause of allergic rhinitis. It also acts as an immunomodulator and has anti-inflammatory properties. Furthermore, it inhibits the activity of nuclear factor-kappaB and other pro-inflammatory cytokines. This makes it a great alternative to medications that can cause side effects.

Inhibits proliferation of cancer cells

Quercetin inhibits the proliferation of cancer cell lines in several ways. First, it inhibits cell proliferation by inducing apoptosis. Second, it inhibits cell cycle progression by inhibiting the PI3K/Akt and ERK signaling pathways. Quercetin inhibits cell growth in various cancer cell lines, including liver cancer cells.
