4 Gauge Ingredients

4 Gauge ingredients

Roar Ambition seems to have put a lot of effort into making 4 Gauge.

4 Gauge s entirely made from few natural ingredients with no artificial sweeteners, which make it stand out in the industry.

Have a look at each.

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. Last but not least, L-Citrulline Dl-Malate increases energy production, which boosts endurance, and enhances performance.
Creatine Monohydrate (1000mg)
Creatine monohydrate increases phosphocreatine levels in the muscles, which enhance the production of adenosine triphosphate (ATP) -the source of energy for muscle contractions. Also, it increases muscle growth, stimulates the release of IGF-1, a hormone that promotes muscle mass, enhances strength, and supports improved performance. A study 1 published in the Journal of the International Society of Sports Nutrition shows that creatine monohydrate increases exercise capacity and muscle growth during workouts. A large number of studies show that Creatine Monohydrate is safe to use and improves exercise performance better than other forms of creatine.
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 receptors in the body that can bind to free testosterone.
Red Beet Root Extract (300mg)
Red beet is rich in fibre, 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. A 2010 study 2 showed that individuals who took beetroot juice before training reported a significant increase in endurance and VO2 max (maximum cardio output) compared to those who took a placebo. Researchers found out the bodies of those who took beet juice utilized ATP more efficiently.
Coconut Water Powder (300mg)
Coconut water powder is considered a significant way of hydrating during intense training and providing the body with minerals needed during the workout- more superior than water and other sports drinks. 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.
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. So how is this beneficial in a pre-workout? A good pre-workout contains caffeine due to its stimulating effects. However, as much as it increases your energy levels, it can elevate your heart rate, blood pressure, and temperature resulting in jitteriness, anxiety, and irritability. L-Theanine boosts the effects of caffeine and offsets the side effects. 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.
Caffeine Anhydrous (150mg)
Caffeine Anhydrous is famous for its stimulating effects to boost alertness and energy levels. It 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. Adenosine is responsible for slowing brain activity and making you sleepy. Therefore, caffeine keeps you alert and awake for longer. Besides, it stimulates serotonin, dopamine, and epinephrine- neurotransmitters that boost energy, reduce fatigue, and increase focus. Last but not least, caffeine improves calcium utilization in the muscles, which increases strength and performance.
Rhodiola Rosea Powder (100mg)
Often referred to as the golden root, Rhodiola Rosea increases endurance, boosts focus, and lowers fatigue. Thus, you will focus more on your workouts, train for longer, and enhance your results. Rhodiola increases focus by boosting neurotransmitters-dopamine and serotonin, which enhances alertness, focus, and memory. It also improves oxygen flow to the muscles, which increases energy resulting in reduced fatigue and improved performance and endurance.
