ARNOLD HIGHLIGHTS: QUERCETIN, A POWERFUL, NOT FULLY EXPLOITED NATURAL ANTIOXIDANT

Quercetin, a member of the flavonoids family, is one of the most important dietary antioxidants. It is widely present in foods including vegetables, fruit, tea and wine and is claimed to exert beneficial health effects.

Especially the ability of Quercetin to scavenge highly reactive species such as peroxynitrite and the hydroxyl radical probably has beneficial health effects.

At Arnold, we saw a complete product line based on fortification with quercetin, with energy drinks, soft chews, liquid concentrates and powder drinks.

On April 8 2011 EFSA published a new opinion concerning quercetin, rejecting the health claim ‘ Quercetin contributes to the protection of DNA, proteins and lipids from oxidative damage’, concluding that a cause and effect relationship has not been established between the consumption of quercetin and protection of DNA, proteins or lipids from oxidative damage. This makes quercetin less attractive as a food supplement ingredient.  (Updated 11/04/2011 with EFSA opinion)
