Anyone who tells you to ingest anything other than your 5 a day is most definitely trying to sell you something! Sadly people fall for it all the time. Longitudinal studies actually suggest that people who take supplements have shorter life spans than those who do not. In fact the only supplement ever to have been correlated with longevity is Vitamin D.
Eat well people- it is what you choose to eat that makes you what you are!
