That is a load of crap I have been mega dosing vitamin c for years and it gives me good complexion and help with immune system I haven't had the flu in years.
Proof.
I need the last 6 years of receipts that verify the vitamin c purchases as well as a Doctor's validation, this must be done by an accredited and licensed physician with at least 10 years of documented medical practice, that you've been influenza free for the last 5 years.
The 1 year gap allows time for the vitamin c to become effective.
Thanks.
