What Are Pre Workout Supplements?

Before we get stuck into this article, first you’ll need to know what pre workout supplements are.

Now, we’re writing this for a range of people; from those that have just began their fitness journey, to others who have more advanced knowledge of supplements.

So stop complaining that you know what these products are and skip to the next section if you do, bro…

The question answered 

Simply put, pre workout supplements are designed to be taken around 20-30 minutes before your gym session – in order to deliver benefits needed to help you progress faster.

What are the key benefits pre workouts should offer?

  • Energy boosts
  • Improved focus
  • Increased strength & endurance
  • Enhanced muscle pumps

The last bullet point is why many believe consuming L-Arginine is a good thing. However, we’ll take you through everything you need to know about this ingredient.

By the end of this article, you’ll know whether L-Arginine is a useful addition to a pre workout or not.

What Is L-Arginine?

L-Arginine is basically an amino acid that’s naturally found in food sources; such as turkey, pork, chicken, seeds, beans, legumes and dairy.

However, you can’t achieve an optimal amount of L-Arginine from these foods. And because it has a poor absorption rate, it’s not the best addition to oral supplements.

What does it do? 

You’re probably wondering what L-Arginine is actually supposed to do.

Well, this amino acid plays an important role in regulating your nitric oxide levels; simply put, an increase in L-Arginine has shown to directly improve your blood flow.

Ultimately, increased blood flow leads to you experiencing enhanced muscle pumps in the gym (which improves your endurance and reduces muscular fatigue).

Poor absorption rate 

We briefly mentioned this at the start of this section.

Well, L-Arginine has shown to have a poor absorption rate when orally supplemented – meaning your body doesn’t make full use of this nutrient when consumed in a pre-workout.

As a result, this means that L-Arginine isn’t actually able to increase your nitric oxide levels in pre workout supplements.

There is a better alternative that’s proven to get the job done. But let’s see if L-Arginine can cause any side effects first.

Side Effects of L-Arginine

Increased risk of cold sores 

Right, so we’re not saying that L-Arginine directly causes cold sores. You should know that both cold sores and genital herpes are caused by the HSV type 1 virus.

However, it can cause an increase in cold sore & genital herpes outbreaks.

Here’s why; L-Arginine can lower levels of L-Lysine when orally consumed.

Basically, L-Lysine is an essential amino acid that can help prevent cold sores and genital herpes, so a reduced amount of L-Lysine in your body is bad news.

However, it’s worth noting that the studies have shown that only dietary L-Arginine can put you at risk from this side effect.

Better Alternatives

We’ve mentioned that L-Arginine has a poor absorption rate, and when orally consumed, can even increase outbreaks of cold sores and genital herpes.

So understandably, we’d rather try some other options.

Well, this is when we began researching about the different forms of amino acids, and whether any could be a direct replacement for L-Arginine.

Ultimately, the best nutrient we found was L-Citrulline.


In case you’re unaware, L-Citrulline is an amino acid naturally found (and extracted from) watermelons.

It’s able to convert into L-Arginine once in your kidneys; this takes away L-Arginine’s poor absorption rate issue. And because you’re not consuming L-Arginine orally, you won’t be at increased risk from cold sores or genetial herpes outbreaks either.

We did pretty good, didn’t we?

Well, after taking a closer look at this nutrient, we found that L-Citrulline had proven to be reliable at enhancing muscle pumps in numerous studies – making it reliable too.

How does it work?

We mentioned that L-Citrulline converts into L-Arginine once in your kidneys.

Well, studies have shown that this is effective at raising your nitric oxide levels; this leads to increased blood flow, which results in you experiencing enhanced muscle pumps in the gym.

But one thing you need to remember, is that L-Citrulline has only shown to work in dosages of 3,000mg and above.

Citrulline Malate

You might be wondering ‘what makes this any different from L-Citrulline?’. 

Simply put, Citrulline Malate is L-Citrulline with added Malic Acid. This means that Citrulline Malate comes with the added benefit of being able to enhance your strength and endurance.

How does it work? 

As Citrulline Malate contains L-Citrulline, it works in the same way.

However, the Malic Acid is able to raise your ATP levels (in a similar way to creatine monohydrate).

In case you’re wondering what ATP is, it’s basically what your body uses as energy (which is why it’s able to deliver these benefits).

  1. Thank you so much for this, I have been using pre work out and creatine for six months and wondering why I kept having reoccurring cold sores when I hadn’t had one in years. I stopped taking everything because I was so sick of it, but have been lacking in my work outs. So thank you again. Btw I’m a 40 year women and am in the best shape of my life and want to stay that way. If you have any more recommendations regarding no arginine products let me know.
    Bless you

  2. This is misleading information for people suffering from cold sores! Citrulline Mullate converts to arginine and at a dosage of 6000MG that is more likely to give people cold sores considering it is an higher dosage more than regular arginine pre workouts at 1G.

    So I would consider re-phrasing the information as this is misleading people to purchase the product!

  3. I know first hand citrulline causes cold sores and shingles fairly quickly. In the first week. It’s even more harsh at times on the virus in my opinion. I used citrulline because of another article I read like this. Shortly realizing it was a huge mistake. I never get cold sores ever. That is unless I take arginine or CITRULLINE
