quercetin/rye flower pollen/bromelain/papain supplement

An herbal nutritional supplement composed of a proprietary mix of the bioflavonoid quercetin, an extract of rye flower pollen, bromelain and papain, with potential anti-inflammatory and antioxidant activities. Upon administration, the quercetin/rye flower pollen/bromelain/papain supplement may exert antioxidant and anti-inflammatory effects and may relieve prostatitis symptoms. The antioxidant and anti-inflammatory effects of quercetin may be mediated through the inhibition of the lipoxygenase and cyclooxygenase pathways, thereby preventing the production of pro-inflammatory mediators. Bromelain and papain act by enhancing the absorption of quercetin, leading to a greater efficacy. The rye flower pollen extract may have anti-inflammatory properties through inhibition of prostaglandin and leukotriene synthesis.
