Vitamin D-3. Get it cheap at WalMart. No flu. No colds. No more, ever.
Well that is not true. I take Vitamin D-3 and I take lots of orange juice for vit. c. I can still get the flu. I also try and wash my hands etc. but there aer times when I have still gotten the flu and colds.
I do believe vitamin D-3 will help with reductions in the flu and colds and reduce the length of a cold. It will also help boost the immue system. Vit. D-3, however, does not stop it.
