Info: 120 or 240 Veg. Capsule Sizes

This formula is temporarily unavailable from the manufacturer; please see Natural Factors Quercetin, as well as Quercetin and Quercetin Bioflavonoid Complex from New Roots Herbal.

Quercetin is a naturally occurring bioflavonoid (found in some berries, onions, and green tea) which acts as an anti-inflammatory to help sustain a balanced immune response, support healthy histamine levels, and reduce seasonal allergies by counteracting the protein complex NF-kB (which plays a key role in regulating the immune response to infection).

Product Notes:

NOW's Quercetin is from a non-citrus source, making it suitable for those with specific fruit allergies. Bromelain, an enzyme derived from pineapple stems, also supports healthy immune system function, and enhances the absorption of the Quercetin. It's also been discovered they can help relieve the pain of nonbacterial chronic prostatitis, especially in combination.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) may afflict over 6% of men, at some point (even as teenagers); it's characterized by pelvic or perineal pain lasting over 3 months, without evidence of urinary tract infection. Quercetin is one of the few effective therapies for that, and Bromelain increases its effectiveness.
