Narrator: This is Science Today. The most potent antioxidant on the market today is Pycnogenol, a pine bark extract rich in flavinoids. Lester Packer, a researcher at the University of California, Berkeley, says among Pycnogenol's beneficial attributes is its ability to keep vitamin C in the system longer.
Packer: Antioxidants in our body that protect us actually interact, or talk to each other. And so just like metabolism is connected together, our antioxidant network exists and is connected together. And we found that flavinoids, pycnogenol and other natural extracts and purified flavinoids can interact with this antioxidant network.
Narrator: This may explain why flavinoid-rich fruits, vegetables and red wine have a positive effect on health.
Packer: I think that discovery is very important and the significance of it is much broader than just pycnogenol because it means that all these fruits and vegetables that we eat that contain these kind of components, will have the same kind of effects.
