In this article, we’re going to bring you some of the key things to bear in mind when it comes to L-Arginine and selecting a pre workout supplement in general.

Pre workouts are some of the most popular supplements in the health and fitness industry, and there are loads of products to choose from when it comes to selecting a supplement to be able to support your training goals.

So, with the introductions out of the way, let’s start taking a look at L-Arginine and pre workout supplements in a bit more detail.

What Is L-Arginine?

L-Arginine is an amino acid that is obtained from the diet and necessary for the body to make proteins.

You probably already know that most ‘essential’ amino acids are required from the diet and act as the so-called ‘building blocks’ of protein in the body.

L-Arginine is found in foods such as red meat, poultry, fish, and dairy products and can also be made in a laboratory.

Interestingly, L-Arginine has been traditionally classified as a ‘semi-essential’ or ‘conditionally essential’ amino acid, which makes it something of a ‘halfway house’ when it comes to amino acids.

L-Arginine is a common pre workout supplement ingredient because of its supposed benefits related to Nitric Oxide in the body.

For this reason, you’ll find plenty of pre workout supplement manufacturers make a big deal about the fact that it’s included in their formulas.

However, you may be looking for a pre workout without L-Arginine due to personal preference or for other reasons, so read on to find out more.

What Is A Pre Workout?

You probably already know all about the basics when it comes to pre workout supplements, but let’s quickly cover some of the key things to consider.

Pre workouts are supplements that are designed to be consumed before periods of exercise to help support you through your training.

They usually contain a range of different ingredients such as vitamins, minerals, amino acids and stimulants.

Most pre workout supplements use a dose of a stimulant such as Caffeine in their ingredient lists, but there are also plenty of options out there that feature ‘stimulant free’ formulas.

The large majority of pre workout supplements are delivered in a flavoured powder form, which is designed to be mixed in with water and consumed as a drink before starting your exercise session.

That said, there are also other pre workouts that are delivered in a capsule form instead of a powder.

It’s worth bearing in mind that pre workouts are not ‘magic powders’ that will work with no effort on your part.

They are supplements which, combined with the right healthy lifestyle choices, can help to support you through your periods of exercise as you look to hit your health and fitness goals this year.

Potential L-Arginine Side Effects

As always, we strongly recommend that you speak to your doctor before thinking about taking a new supplement for the first time.

This will ensure that you are able to discuss the ingredients label in full with a certified medical professional in order to assess whether a supplement is right for you or not.

As with most supplement ingredients L-Arginine has the potential to cause some unwanted side effects.

According to WebMD, some of the side effects L-Arginine may cause include: abdominal pain, bloating, diarrhea, gout, allergies, worsening of asthma, and low blood pressure.

WebMD also says that because of lack of verifiable research, you should stay on the safe side and avoid use of L-Arginine if you are pregnant or breastfeeding.

The bottom line here is that L-Arginine should be used with caution. This is why it’s always best to speak to your doctor before trying any new supplement, or making any major lifestyle changes.

4 Gauge Roar Ambition

4 Gauge also uses a 150mg dose of Caffeine per serving as part of its formula. To put this amount into context, you’d expect to find around 100mg of Caffeine in a regular cup of coffee.

Here is the active ingredients list of 4 Gauge, which was shown on the official website at the time of writing:

Anything Else To Consider?

As we mentioned above, it’s always best to speak to your doctor before taking a new supplement for the first time, or making any major lifestyle changes.

Supplements such as pre workouts are not intended to replace a varied, balanced diet, and a healthy overall lifestyle.

It’s always a good idea to get the basics right when it comes to your health and fitness before thinking about adding a supplement to your regimen.

Sticking to a varied and balanced diet, following a sensible workout plan and ensuring that you’re getting enough restorative sleep are three main building blocks to overall good health.

Supplements can play a role in assisting alongside an already healthy lifestyle, but it’s best not to regard them as ‘magic’ powders or pills that will work without any effort on your part.

It’s also important that you carefully check the label of any supplement you’re thinking of taking. As we mentioned above, check the ingredients formula shown on the official website of any supplement you’re thinking of buying before making a purchase, as manufacturers may tweak or update their formulas from time to time. If you have any questions or concerns, contact the manufacturer to find out more.
