Quercetin 250 mg, 60 caps

Quercetin 250 mg - Everyday immune support

Quercetin is a natural flavonoid found in fruits and vegetables that has been part of the human diet for generations. Quercetin is valued for its strong antioxidant profile, which is why it often appears in formulas that support the body's daily balance - especially when it matters to protect cells from oxidative stress.

Quercetin's antioxidant profile is one of its most recognisable features. It helps reduce the effects of free radicals and oxidative stress. In laboratory conditions, its activity against selected bacterial species has also been described, including Helicobacter pylori, Salmonella enterica serotype Typhimurium, Micrococcus luteus, Yersinia enterocolitica, Pseudomonas aeruginosa, Escherichia coli, S. aureus, P. fluorescens, Campylobacter jejuni and Staphylococcus epidermidis.

Antifungal activity

Laboratory studies have described quercetin's activity against various fungi, including some Candida species, Cryptococcus neoformans, Aspergillus and dermatophytes. The publications discussed mechanisms including effects on oxidative stress and cell membrane properties. The possibility of synergy with selected substances tested for antifungal activity was also pointed out. According to Rocha et al. (research)

Reduction of oxidative stress in the brain

In the literature, quercetin has been described in the context of neuro-oxidative processes, including through its antioxidant potential (ROS scavenging), effects on lipid peroxidation and activity of selected antioxidant enzymes. Its effects on neuroinflammation in research models were also discussed, including by modulating the activation of microglia and selected pro-inflammatory cytokines. (Studies 1, 2)

Senolytic agent

In the literature, quercetin is sometimes described as a compound analyzed in the context of cellular aging processes and the reduction of pro-inflammatory signals associated with aging. It also appears in scientific discussions in the context of increasing NAD levels.

Quercetin also plays a role in cell signalling, effective communication between and within cells. It helps create signaling pathways that respond and adapt to the internal and external environment. These pathways are essential for supporting many cellular functions to maintain and promote health. When cell signaling pathways work properly, the body functions efficiently.

Inflammation is the body's normal response to injury or infection, while its chronic activation is discussed in the literature as a component accompanying various metabolic processes. A study published in the Journal of Nutritional Biochemistry described changes in inflammatory response markers after quercetin supplementation in an animal model. (research)

Anti-inflammatory effects

It has been shown that quercetin can affect selected pathways involved in the inflammatory response, including by modulating the production of pro-inflammatory compounds, which is discussed as a potential mechanism to support the body's balance.

In addition to its antioxidant properties and effects on inflammatory processes, quercetin has also been studied for its potential in the area of performance. Studies have indicated that quercetin supplementation can support selected parameters of endurance and physical performance. It is discussed that effects on oxidative stress and inflammatory processes may play a role in these observations. A study published in the Journal of the International Society of Sports Nutrition described improvements in selected endurance parameters in cyclists. (research)
