How Does 4 Gauge Work?

4 Gauge is a pre-workout supplement that enhances your exercise performance during each workout session and gives you phenomenal results.

It employs four primary mechanisms with a rich blend of natural ingredients that have been well-evaluated and backed up by science.

4 Gauge contains adaptogens that boost focus, alertness, and concentration, thus, allowing you to get more out of your training sessions.

4 Gauge Pre-workout Ingredients

1) L-Theanine (200mg)

L-Theanine is an amino acid that stimulates the release of GABA, a brain neurotransmitter that boosts mood, relaxation, and focus.

GABA triggers a calming effect, allowing you to focus more without feeling sluggish or drowsy.

A combination of caffeine and L-Theanine is referred to as smart caffeine.

L-Theanine makes sure that the energy from caffeine is utilized where it is needed, therefore no more anxiety or jitters. Besides, it prevents post-workout crashes.

This is an amino acid that is found in tea leaves. L-Theanine is often paired with Caffeine in the same supplement–and that’s exactly the case with 4 Gauge.

2) L-Citrulline Dl-Malate (6000mg)

L-Citrulline Dl- Malate is a blend of L-Citrulline and malic acid.

It enhances the ammonia recycling process, which facilitates toxin removal in the body.

Ammonia is a byproduct of exercise that leads to fatigue, hence reducing performance.

Also, it stimulates nitric oxide metabolism, which promotes vasodilation and blood flow to the muscle cells. This increases endurance and stamina.

The body changes L-Citrulline Dl-Malate into L-arginine, which changes to nitric oxide, a vasodilator.

Therefore, muscles receive more oxygen and nutrients to support exercise capacity

3) Caffeine Anhydrous (150mg)

Caffeine Anhydrous is famous for its stimulating effects to boost alertness and energy levels.

It is used in pre-workouts to enhance performance, improve recovery, and accelerate results.

Caffeine passes the blood-brain barrier and binds to the adenosine receptors preventing adenosine activity

4 Gauge uses a sensible-seeming dose of 150mg of Caffeine Anhydrous per serving.

To put that amount into context, you’d expect to find about 100mg of caffeine in one cup of coffee.

4) Coconut Water Powder

Coconut water is full of electrolytes that help to rehydrate your body, which is extremely important after intense and regular workouts.

It is rich in natural electrolytes that keep you rehydrated during intense training.

Electrolytes are essential minerals and salts vital to your health, especially the immune system.

They are responsible for transporting nutrients and water to the muscles to keep you going for longer.

Also, coconut water powder contains high levels of potassium that prevent muscle cramps during intense physical activities.

Last but not least, it is full of antioxidants that prevent the accumulation of free radicals, therefore, protecting muscle cells from stress.

Each serving of 4 Gauge uses 300mg of Coconut Water Powder: per serving.

Potassium–Each serving uses 10mg of Potassium. Potassium is an essential mineral that contributes to the normal functioning of the nervous system and normal muscle function.

Calcium–It also contains 30mg of the important mineral Calcium. Calcium contributes to normal energy release and normal muscle function.

5) Acetyl L-Carnitine (500mg)

Acetyl L-Carnitine is an amino acid that increases energy production in the body.

It supports the body to transfer fatty acids into the mitochondria, where they are converted to energy.

Also, it is a potent antioxidant that crosses the blood-brain barrier and increases concentration, focus, and alertness.

Acetyl L-Carnitine increases athletic performance- it helps the body to utilize more testosterone by boosting androgen effectively.

Mainly a fat burner, acetyl L-carnitine also helps to prevent muscle damage and fatigue.

The compound helps to transport fatty acids to cells that convert fat into energy.

So, while helping to burn fat, the acetyl L-carnitine gives you the energy boost required during strenuous workout sessions and a serving of 4 Gauge has 500 mg of acetyl L-carnitine.

The main benefit of this difficult to pronounce amino acid is as a fat burner.

The added benefit is that you get an energy boost simultaneously, which helps during tough workout sessions.

The more L-carnitine you have in your system, the easier it is for your body to burn off some fat.

6) Creatine Monohydrate (1000mg)

Creatine monohydrate increases phosphocreatine levels in the muscles, which enhances the production of adenosine triphosphate (ATP) -the source of energy for muscle contractions.

Also, it increases muscle growth, and stimulates the release of IGF-1, a hormone that promotes muscle mass, enhances strength, and supports improved performance.

A study published in the Journal of the International Society of Sports Nutrition shows that it increases exercise capacity and muscle growth during workouts.

7) Red Beet Root Extract (300mg)

Red beet is rich in fiber, potassium, and nitrate.

Your body converts these nitrates into nitric oxide (NO), which widens your blood vessels and boosts blood flow to the muscles.

This facilitates more nutrients and oxygen to the muscles. This means enhanced performance and increased endurance.

Red Beetroot Extract L-Citrulline Dl-Malate is an amino acid extracted from watermelons and it shares an important ability with red beetroot.

Both ingredients boost nitric oxide levels.

In so doing, they provide a benefit called vasodilation.

This is a slight widening of the blood vessels.

It occurs naturally during exercise, but boosting nitrogen levels improves the effect. Vasodilation improves the circulation and this offers a few interesting benefits.

The blood is responsible for providing the muscles with nutrients and oxygen and the need for both increases during exercise.
