SISU Nature's Defence
60 Capsules
SISU Nature's Defence are antioxidants for the maintenance of good health.

  • Quercetin has been shown to inhibit the release of inflammatory compounds like histamine without the side effects of pharmaceutical antihistamines
  • Quercetin is found in many common foods; quercetin in Nature’s Defence is derived from a Brazilian shrub
  • Grape seeds are a rich source of antioxidant bioflavonoids that also have anti-inflammatory properties
  • The effects of quercetin and grape seed are cumulative, so many people start taking the product a few weeks before allergy season begins to support and strengthen the immune system against the allergic response

CHRISTINE: more than a year ago

I am taking this to combat my hayfever. Wish the capsules were high dosage so I could take fewer capsules.
