Does Vitamin C Help Prevent Cold Sores?

Let’s talk about C. Vitamin C.

Because for as long as humans have found out they can make money selling vitamins, C has been the undisputed champion.

And stories of its triumphs is the stuff of legends, ranging from preventing colds to full-blown cancer curing.

Now, I have my reservations about the whole cancer thing.

Because I have a hard time figuring out why something so common would NOT be used more often to fight cancer if it’s actually effective.

(well, not without going full-blown conspiracy theorist on you…)

But as you should know by now, I’m more concerned about cold sores.

What I want to know is whether or not vitamin C can help prevent cold sore outbreaks from coming back all the damn time, or at least make them less of a pain in the butt.

After all, it’d make for a cheap, quick and easy treatment, right?

So I done gone diggin’.

And it turns out… the answer isn’t clear.

Yes, there’s an old study from the seventies that found that people who took a concoction of vitamin C and flavonoids managed to cut the healing time of their cold sores in half (or something).

Sounds good, right?

The problem here is that it’s not clear if the reduction in symptoms was due to the vitamin C or the flavonoids…

Plus, a lot of studies from that era aren’t always reliable (COUGH-arginine-COUGH!). Not sure it still holds up.

And there haven’t really any follow-up studies done since.

However, other studies done on the shingles virus (i.e. herpes zoster, a virus closely related to HSV) have found compelling evidence to support the use of vitamin C.

Does this translate to cold sores? Who knows…

But at the end of the day, taking vitamin C isn’t stupid. I think it’s safe to say it’s earned its reputation as an effective infection fighter and a good way to give your immune system a helping hand. And cold sores are indeed, an infection.

Plus, it’s like super cheap.

But that doesn’t mean you need to go out and buy a big bottle of the stuff.

See, a lot of foods contain more natural vitamin C than your body needs anyway (on top of other super important nutrients, like other vitamins, minerals, fiber, etc. All stuff your body needs to keep you infection free).
