As we are all bundling up and trying our best to avoid the flu bug that seems to be everywhere, one thing that you can do to build your immunity is take Vitamin C.
I know it may sound cliche, but take it from someone who works in patient care and am surrounded by sick people (germs) on a daily basis.
Initially, I started taking the Vitamin C micro-crystals when I started feeling lethargic and like a cold was coming. Now I try to take it daily, especially seeing all the positive flu cases and my clients who are out sick.
1 scoop (teaspoon) mixed with water (more or less depending on your tolerability to the sour taste). It takes like strong lemon water to me, but some people don't mind it at all.
You can purchase this one at any health food store like Moms or Whole Foods.
Don't forget to continue to sanitize your hands, items like shopping carts, and any other things that are of public use.
Stay warm and stay healthy!
