Phytoshield is a potent & powerful phyto-antioxidant nutrient containing high levels of flavonoids and carotenoids. It has wide-ranging activity: anti-inflammatory, antibacterial, antihistamine and membrane stabilising. It's a brilliant supplement for travel where sun exposure is high and at times when diet and alcohol choices might not be optimal. Flavonoids: - bestow anti-inflammatory and membrane stabilising properties. - serve as protective nutrients in plant tissue to protect the plant (& in particular its DNA) against external threat. Once consumed by humans they act in the same way. - Flavonoids, especially Quercetin, have been shown to help prevent virus entry into cells & obstruct viral replication. - Often water-soluble, most flavonoids and are only stored in the body for short periods of time, hence, it is important to have regular intake of these important nutrient groups.
