which vitamins?

[countydurhamlass]

As i get older (I am only 33) I have noticed in the winter colds get more frequent and last longer so i am thinking i should start taking vitamins to help boost my immune system particularly to help fight a cold. I am thinking vitamin c is the right way to go but are their others i can take either instead or alongside vitamin c. i have had the latest cold/flu bug now for two weeks!

Zinc is also meant to be good for boosting immune systems. And there's echinacea, not a vitamin but a herb, but I think there's some quite good evidence it helps to prevent colds.
