My Cold Sore Story

After years of dealing with cold sores on and off since my first relationship (yes, I was unlucky enough to get them from my very first girlfriend), they had started to affect me more and more regularly as I got older. By the time I hit my 30's, it wasn't unusual for me to get cold sores every month or so. Considering these horrible pesky things can last up to 2 weeks to properly heal from the scabs, that's a lot of time having cold sores.

We all know how frustrating, annoying and just literally disgusting cold sores are to have to deal with, and there's no one that enjoys having to go through this process. When I had them bad, I would literally feel HATRED towards the virus (herpes labialis) and it's putrid effect on my life. I'm sure that didn't help, as they seem to be more likely to happen when going through emotional stress and strain.

Cold Sores Like Bad Weather Hey?

Anyway, I noticed that I would get them a lot when I was living in Edinburgh, Scotland for a couple of years, especially when it was windy. It seems that they are more likely to occur when your lips get dried out, and especially if the other causes (which we'll get to) are there as well. This was definitely the case with me, and when I was partying a lot, feeling run down, and then experiencing that in combination with the windy weather, I'd get cold sores VERY often.

I discovered that drying them out was quite important early on (once you already have the coldsores, it's actually better for your lips to be a bit dehydrated in my experience, as they spread with moisture), and so a large part of my remedy back then was simply a cold sore treatment from the chemist which was mostly watered down alcohol. The alcohol works well to keep the skin dehydrated, which stops the cold sores spreading more. I still believe drying them out is really a big part of my approach to curing cold sores, although I'm not sure what method for drying them out is necessarily the best at this point.

If you've had them any number of times, you will get that it's those puss-filled little bubbles which are the really contagious part of the physical wound, and keeping that as small and as least pussy and gross as possible is an important part of staying on top of them, drying them out helps immensely with this part of the healing process.

Anyway, I had heard of L Lysine/L Arginine and their connection to getting and repelling cold sores some time ago, probably when living in Edinburgh as I mentioned. However, it wasn't until just very recently that I feel I really cracked the code with getting rid of these buggers fast. Here's how it happened…

Cold Sores Threaten To Ruin My Date

It began recently when I was a little run down and had a hot date coming up, and was aware of avoiding cold sores for this special day so I wouldn't repel my date before I'd even had a chance to get to know her… Despite being reasonably careful and aware of the possibility of this and taking what I thought was quite a bit of L Lysine when feeling the itching coming on as a precaution, what do you know, two days before my date and I start to get those little bumps of cold sores on my nose (the first physical signs) along with some pretty severe itching to go with it.

So, as you can imagine, I'm pretty pissed off. “___ING COLD SORES!!!! GO TO HELL!!!” is pretty much what I found myself yelling into the bathroom mirror. I can't believe it. Even after being pretty aware and careful all week, the little pricks had snuck in the back door literally at the worst time possible. About 2 days before the date, which meant that by the actual date day, I'd have some big sexy (not at all sexy) blistering cold sores on hopefully both my nose, and mouth… I really liked the girl too, and was hoping to make a good impression, so I wasn't happy at all.

So at that point, my frame of mind is pretty much “That's it, time to take some drastic measures”, and I spoke to a friend about my predicament. He mentioned mega dosing L Lysine, which I agreed with, and thought I'd already been doing for several days, as I had felt the itching coming on. He also had some other suggestions about hiding the cold sores, should it come to that, using BB cream, similar to a tinted moisturiser (something I wasn't really familiar with, but willing to try nonetheless). The cover up solution was helpful, but I really didn't want it to get that far.

I read up on things again regarding overcoming cold sores, and minimising their annoying disgusting mess, and all the things I had previously read rang a little louder, as I was prepared to really make as much effort as possible at this point.

This time in my suffering from cold sores led to the following method, which I really do think is amazing in how quickly it's worked for me, and while I'm sure it could be tweaked a little in terms of dosages etc (and of course will be dependent on many factors to do with your own genetics, health status and lifestyle), it's pretty damn incredible as it stands right now.

I hope you will give it a try, and I'm super hopeful that it will work as quickly and powerfully for you as it did for me. Please do share your experience if you have any thing to add on this topic, you can leave comments below the article.

My Cold Sore Prevention Method

So below is my approach to getting rid of these nasty things, and stop them coming back. Before you write it off as being too simplistic or whatever, and dismiss my information as rehashed, or “not fast/powerful enough” please check the area where I discuss my results here (especially the updated section, as more recently I've really not had any issues with cold sores at all – with absolutely none in the past 8 months)

One of the good things about this treatment is that it's all natural. You don't have to take any toxic chemicals or anything like that, there's enough toxicity in our environment already without adding any more into your body unnecessarily.

I should be straight up here by saying that this method of preventing and stopping cold sores in their tracks is by no means my invention, I just tried lots of things that were already being suggested, and kind of puzzled them together to make something that really works for me, and I'm hopeful it can be as effective for others as it's been for myself.

So without further adu, let's get to the meat and potatoes of this cold sore remedy.

Mega Dosing Of The Following:

Complete Avoidance Of The Following:

  • Nuts, seeds, grains
  • Acidic foods (Tomatoes, Citrus fruits, etc, etc)
  • Sugar (it might be hard to totally avoid, but minimise it as best possible)

I will get into the science of why I believe this works shortly, and the mechanics of starving cold sores. But for now, it's important that you realise how simple this is to do, it just takes a little discipline. See, from my personal story above, that week where I had my cold sore “epiphany” the whole week I'd been having the warning sign of itching on my nose (I quite often get them just on the bottom of my left nose, and not necessarily on the lips or mouth at all).

Because of the itching and my concern of getting a cold sore right before my date, I was already taking quite a lot of L Lysine, and Zinc, BUT I wasn't being careful enough about NOT consuming the things on the avoidance list (especially the nuts, etc, which contain Arginine, which is one of the main “food sources” for the cold sore virus).

The L-Lysine pictured to the right is the one I personally use most of the time, but any strong L-Lysine supplement will probably do the trick. Here is a link (Amazon) to a personally trusted brand (Solgar) that I usually go for, if you want to source it online.

As far as the supplement dosages, I've simply put the first day of treatments RECOMMENDATIONS based on my own personal experience. I'm a rather big guy, so if you're a small-ish woman, then it's likely you would need lesser amounts than what worked for me personally.

Remember that this is your body, your health, and your own personal experience to see how this works for you. So the smart thing to do would be to titrate up gently over time. Start off with lower amounts, which you're comfortable with, and then gradually increase it until you notice it working to fight off and stop the cold sores in their tracks.

Another thing to mention is the timing. I believe that it's crucial to implement this cold sore killing protocol AS SOON AS you start noticing the itching, as that's the bodies first warning sign, and I believe it's actually the cold sore virus moving its way from your nerve cells underneath the skins surface, towards the surface of the skin. If you start megadosing the Lysine, Zinc and Vitamin C as soon as you notice the itching, you're giving yourself the best possible chance of stopping it quickly, and making it's occurrence a minor thing, as opposed to a major headache.

The Vitamin C is just something I added as I know it has powerful immune system boosting properties, and works well as an antioxidant, so it definitely can't hurt to have a bit extra while you're trying to suppress the cold sores.

In terms of keeping the affected skin area dry, you can use either something like a weak alcohol solution (found at the chemist or online) or you can even try what I use, which is simply a very small amount of toothpaste. While it doesn't look great (neither do cold sores of course) to have dried toothpaste on your mouth/nose, it works very well to cover up the area and dry it, preventing any moisture buildup. I usually only do this for the first day or so.

So that's basically the remedy in a nutshell. As I mentioned earlier, it will probably involve some tweaking from yourself to find the right dosages and personal nuances that make it work for you.

Before I wrap this section up, I can't emphasise enough how important it is to STOP taking all things which are moderate to high in arginine, those primarily being:

  • Nuts and butters made from nut products (peanut butter, etc)
  • Seeds
  • Whole Grains
  • Carob
  • Chocolate
  • Coconut
  • Soy Beans
  • Chick Peas
  • Spirulina
  • Lentils
  • Seaweed
  • Gelatin
  • Watercress
  • Spinach
My Results

Typically a cold sore can last anywhere from 1-3 weeks in my experience. In the past when partially using some of the supplements in this protocol, but not megadosing enough, and also not staying away from the high arginine foods enough to see real results, my cold sores would probably last typically about 10 days (from first emergence to scabs healing).

After applying the above protocol, I found that the growth and spreading of the cold sores are stopped immediately, and then the very small scabs that will have formed from the small starting blisters, will literally be healed in about 2-3 days. Also it should be noted that these scabs are so small that they are barely noticeable, and are not the typical huge ugly scabby things you see on people who've had a bad cold sore. I will update soon with pictures, the next time I get them, so you can see what I'm talking about here.

IMPORTANT UPDATE TO MY RESULTS – Since originally writing this page, I've had almost zero cold sore blisters reemerge. I now realise that dietary considerations are a HUGE piece of this puzzle, and since being much more observant and careful with my intake of arginine containing foods, I've basically had no issues with this.

For me personally, previously I was always eating something in my diet that was either a nut product or contained nuts, like for example peanut butter, or granola/muesli mix. Since cutting way down on high arginine foods I've had these amazing new results where I barely (if at all) have any problems with cold sores.

So try looking closely at your diet if  you keep getting recurring cold sores. The L Lysine, etc mentioned above works really well, but it's just as, if not even more important to lower dietary arginine!

The Lysine/Arginine Connection

L-lysine and L-arginine are amino acids which share common pathways in the body, with L-lysine being suppressed by L-arginine. If you have a high level of arginine in your diet, then you should be aware that it's going to lower your body's levels of Lysine, and this may make you more susceptible to cold sores, especially with the addition of other factors like being over stressed, lack of sleep, lowered immune system efficiency, etc.

While it's hard to find any hard evidence that high levels of arginine will cause cold sore breakouts in those who have already had the viral infection, the fact that L-Lysine seems to work so powerfully against cold sores does point towards this being the case.

Published Studies Supporting This Treatment

Seeing as I don't like to make any claims about things working in any area of health without some kind of basis in science, here's some of the published studies I dug up which support my theory that using simple supplementation of L-Lysine, Zinc and Vitamin C (particularly L-Lysine) can help to prevent and stop cold sores from taking hold or getting worse.

Here's some of the studies I found that correlate with my own experience: 

Other Tips & Resources That Might Help With Cold Sores

Here's some other ideas that might help you overcome your cold sore issues

  1. Remember that the herpes virus and it's physical outbreaks of cold sores on the skin are largely related to how well your immune system is functioning. This is commonly understood by the fact that people often get more out breaks when they are tired, stressed and/or run down, as you might have experienced with your own cold sore problems. Knowing this, it's important to keep your immune system healthy, and this can be achieved by looking after all the basics such as; proper rest and recovery, healthy diet, adequate exercise, relaxation and proper stress management.
  2. There are other products on the market other than just supplements such as this Electronic Cold Sore Treatment Device (amazon link) pictured here. So continue your research and look into additional “weapons” that you can add to your arsenal to lessen the impact of cold sores in your life. (Note – I've not yet tried the pictured device, as it's not really necessary for me right now as my cold sores are no longer a problem since using L Lysine, and lowering my arginine containing foods as I explain above here).
