So, what makes the new Nitros X so impressive?


  1. L-Citrulline Malate: This ingredient is a combination of the amino acid L-Citrulline and malic acid. L-Citrulline is converted to nitric oxide in the body, which helps improve blood flow and oxygen delivery to muscles during exercise. This results in increased endurance, reduced muscle fatigue, and improved performance.
  1. Beta Alanine: This amino acid is known for its ability to increase the production of carnosine in the muscles. Carnosine acts as a buffer to prevent the buildup of lactic acid in the muscles, which can cause fatigue. Increased levels of carnosine can also improve muscle endurance and delay muscle fatigue.
  1. L-Arginine: This amino acid is a precursor to nitric oxide, which helps dilate blood vessels and improve blood flow to muscles. This can lead to improved performance and reduced fatigue during workouts.
  1. Creatine: This compound is naturally produced in the body and helps provide energy to muscles during high-intensity exercise. Supplementing with creatine has been shown to increase strength, power, and muscle mass.
  1. Taurine: This amino acid has many benefits for athletes, including improving exercise performance, reducing muscle damage, and increasing antioxidant activity in the muscles. It may also help improve mental focus and reduce fatigue during workouts.
  1. Caffeine: This stimulant is well-known for its ability to increase energy, alertness, and focus. It can also improve athletic performance by reducing perceived exertion and increasing fat oxidation.
  1. Beetroot Powder: This powder is high in nitrates, which the body converts to nitric oxide. Like L-Citrulline Malate and L-Arginine, nitric oxide can help improve blood flow and oxygen delivery to muscles, resulting in improved performance and reduced fatigue.
  1. Branched Chain Amino Acids (BCAAs): These amino acids, including leucine, isoleucine, and valine, are essential for muscle growth and repair. They can also help decrease muscle soreness and improve endurance during exercise.

This combination of key ingredients in Stealth Supplements Nitros X pre-workout supplement work together to increase energy, improve muscle endurance, reduce fatigue, and enhance workout performance. They also help improve blood flow and delivery of nutrients to muscles, which can aid in muscle growth and repair. Together, they make a powerful combination for a strong pre-workout supplement.


  1. Choline Bitartrate: This ingredient is a precursor to acetylcholine, a neurotransmitter that is essential for cognitive function and memory formation. It helps improve focus, concentration, and overall brain performance.
  1. L-Tyrosine: It is an amino acid that helps produce dopamine, norepinephrine, and epinephrine – all neurotransmitters that are important for alertness, focus, and mood. L-Tyrosine is also known to improve cognitive flexibility and reduce stress.
  1. L-Theanine: It is an amino acid found in green tea that can improve memory, attention, and relaxation. It also has a calming effect and can help reduce anxiety and stress.
  1. Alpha-GPC: This ingredient is a natural choline compound that has been shown to increase acetylcholine levels in the brain, leading to enhanced cognitive function, learning, and memory.
  1. Vitamin B1 (as Thiamine): Thiamine is important for the production of energy and the proper functioning of the nervous system. It is also needed for the synthesis of acetylcholine, making it essential for cognitive function.
  1. Vitamin B2 (as Riboflavin): This vitamin helps with the production of energy and is necessary for maintaining healthy brain function. It also has antioxidant properties that protect the brain from oxidative damage.
  1. Vitamin B3 (as Niacin): Niacin is important for the production of energy and helps improve blood flow to the brain. It also has neuroprotective properties and may help prevent neurodegenerative disorders.
  1. Vitamin B6 (as Pyridoxine Hydrochloride): This vitamin is involved in the production of neurotransmitters such as serotonin and dopamine, which play a role in mood regulation and cognitive function.
  1. Biotin (Vitamin B7): Biotin is important for the health of brain cells and is involved in energy metabolism, which is essential for cognitive function. It also supports myelin production, which helps with neural communication.
  1. Folic Acid (Vitamin B9): Folic acid is essential for brain development and function. It is involved in the production of neurotransmitters and helps prevent cognitive decline and dementia.
  1. Vitamin B12 (as Cyanocobalamin): This vitamin is vital for the proper functioning of the nervous system and is involved in the production of neurotransmitters. A deficiency in B12 can lead to neurological symptoms, including memory loss and cognitive decline.

Overall, these key Nootropic ingredients in Stealth Supplements Nitros X are chosen for their ability to support brain function and cognitive performance. They work together to improve focus, memory, mood, and overall brain health, making them essential for a potent and effective nootropic supplement.

With the combination of the Pre-Workout and Nootropic formula, it makes Nitros X an elite pre-workout and focus supplement and a great option for anyone looking to take their workouts beyond the next level.
