I am starting a new job in a couple weeks which will have me working outside. Out here in Vancouver it rains alot so one thing that worries me is that I might start getting sick.
This is a good paying job so money wont be a big issue for me.
Is their a good supplement to take to really boost up my immune system?
I'm thinking vitamin c for sure. But what else? Glutamine?

Don't let this get out but.... quality sleep.

Also,
exercise
solid clean diet
Whey Concentrates
CoQ10
Probiotics
blueberries
Cat's Claw
old time remedy: garlic
