How to Prevent Cold Sores From Coming Back

How to prevent cold sores

Let me tell you the story of a very silly little girl that didn’t understand germs.

When I was 12 years old, I found a sparkly lip gloss on the floor while I was waiting for the bus outside of my middle school. I picked it up and used it. Ew. I know. What was I thinking? That pretty lipgloss not only gave me Mononucleosis (Mono) but also cold sores.

Mono is often called ‘The Kissing Disease’ because it’s spread through saliva. I got someones saliva in my mouth and I hadn’t even gotten my first kiss yet! The pain didn’t stop there (Mono makes you feel pretty crappy for about two weeks) — shortly after getting sick I also got my first cold sore.

Core sores, also spread with close contact (darn lip gloss), is a form of herpes that makes gross blisters around the mouth area. Yeah, not very attractive.

Now as a disclaimer, I am not a professional medical practitioner in any sense. This entire article is based on googling.

When you get a cold sore it typically lasts for one-two weeks, even if you are treating it with medications like Abreva. After a few years of just dealing with the problem when it came about, I decided to look into prevention sometime during the beginning of college. After a whole lot of googling I found a random small blog (I don’t know which) that mentioned using the supplement L-Lysine to prevent cold sores from resurfacing. Since then many articles have come up on the topic.

L-Lysine as a supplement is often used to help reduce anxiety and lower blood pressure, according to Wikipedia. It is also stated that it helps reduce the incidents of cold sores, although it does not seem to work with everyone. Thankfully for me it has worked perfectly. I started taking it every day and remarkably for a whole year I didn’t have any cold sores.

But then skeptical me thought “Hey, what if it’s just a coincidence?” So I stopped taking it and within a month I had a new cold sore. I was so upset with myself! Through trial and error (I just seem to love testing my own theories) I discovered that I need to take L-Lysine at least three times in a week to not have a blister come back up. Since sticking with this routine, I have been cold sore free.

So there you have it. If you kissed the wrong ‘Frog Prince’ or used a lip gloss you shouldn’t have, now hopefully you can have cold sore relief by taking L-Lysine regularly. It’s available at any local grocer or vitamin shop.

Do you have any sneaky supplement cures you’d like to share? I’d love some more miracle vitamins!

    Count me in! because lysine supplementation really worked to me. I was lucky to get through a month without a single cold sore because almost every month cold sore happens. Thankfully, that it didn’t happen because of my maintenance but I have read a related post with regards to cold sores that you could also try to burn it with ice. Just get an ice cube and a towel and hold the ice cube with the towel and apply the ice directly to the cold sore. I do not know if this works though.

    the ice works because the cold sore needs warmth to thrive and with the ice cube cooling the cold sore down it can not thrive. I’ve tried it and I was relieved that it worked. I haven’t had a cold sore since 2014 around this time.

      When you start to feel the first signs of a cold sore (tingling and soreness the area) is when you start to apply ice. If you wait till the blusters appear, it too late.

    Thank you for sharing your story Rebecca! It is wise to be mindful of sharing makeUp of others even if you know them. I wished I had known about L-Lysine when I was a kid as I had dealt with those sores all the time and sometimes it would be back to back for over 50 years ! I’ve taken the supplement for several years now, when I’m feeling run down or feeling the dreaded “tingling.” That works for me now. It might be useful to be aware of and eat foods that are higher in lysine, it’s something I find beneficial for me. Google is a wonderful tool to use in order to find a list of those foods. Good Job! In being presistant and proactive for a solution.
