Levann "jA" Pre-Workout, 10 sachets

Orange fruit extract containing bioactive hesperidin may be the missing element in your training plan. Intense exercise is a huge challenge for blood vessels. Hesperidin has properties that support vascular capacity and blood flow. [1] With improved blood flow, muscles receive more oxygen and nutrients, resulting in superior performance and better training results. The effects of hesperidin on vascular endurance performance have been extensively studied, and the results are promising.
WATTS'UP® supplementation has been shown to increase anaerobic power at the beginning of exercise, followed by a sustained increase in aerobic power throughout exercise [2] and increased average anaerobic power. [3]

Creatine* works by increasing ATP production, which is crucial for endurance and muscle strength[4]. During intense exercise, ATP (adenosine triphosphate) is used to produce energy. ATP is the main “fuel” for our cells. The stockpile of creatine in the muscles leads to more available phosphocreatine, which in turn allows ATP to regenerate faster and more efficiently.

In other words, creatine helps muscles work more efficiently, which translates into better performance, both in short-term efforts and longer training sessions. Creatine is also beneficial for cognitive abilities, which can result in better focus during exercise[5].

*Creatine enhances physical performance for consecutive short, high-intensity workouts.

Essential protein building blocks that contribute to the growth and maintenance of muscle mass*. In general, these substances support the body at various stages of physical activity, from preparation for exercise, through its duration, to post-workout recovery. In addition, L-citrulline is a substrate for arginine, from which nitric oxide is produce[6].
The result of this process is proper blood flow, which in practice means faster delivery of nutrients to the muscles. L-tyrosine, on the other hand, is a precursor for adrenaline and norepinephrine, responsible for alertness and focus during training as well[7].

Note: Beta-alanine can cause a tingling sensation, which, however, is not dangerous!

*Protein contributes to the growth of muscle mass. Protein helps maintain muscle mass.

These are invaluable allies in the daily life of a physically active person. They are substances that can wring out extra energy, providing the necessary boost of vigor when you need it most. Caffeine is a master at fooling the brain by blocking the action of adenosine, the neurotransmitter responsible for feelings of fatigue[8]. Taurine works synergistically with caffeine, meaning that together they can work even more effectively.

Phosphorus contributes to the maintenance of normal energy metabolism*. It is a key element in the production of ATP, which is beneficial for energy processes and muscle endurance[9]. Phosphorus is also important for enzyme function and nutrient transport in muscle cells.

*Phosphorus contributes to the maintenance of normal energy metabolism.

Zinc contributes to the maintenance of normal macronutrient metabolism, helps in the normal synthesis of protein, in the protection of cells from oxidative stress and in the maintenance of normal testosterone levels in the blood*. One of the most important aspects of its action is precisely its effect on levels of testosterone, a hormone essential for proper muscle growth and recovery. Zinc is also beneficial for enzyme function, which is important for energy metabolism. This is because it optimizes biochemical processes, which is crucial for maintaining full energy and vitality.

Zinc also helps the immune system function properly. It plays an important role in maintaining a healthy immune system, which can be compared to a fortress that fends off all infections. It is what makes the body's regeneration faster and more effective.

*Zinc contributes to maintaining normal macronutrient metabolism. Zinc helps in proper protein synthesis. Zinc helps protect cells from oxidative stress. Zinc helps maintain normal levels of testosterone in the blood. Zinc helps in the proper functioning of the immune system.

Pantothenic acid contributes to maintaining normal energy metabolism and reducing feelings of fatigue and tiredness*. It is a key component of coenzyme A, which is essential for energy production in cells[10]. Coenzyme A is also important for the synthesis and metabolism of proteins, fats and carbohydrates. This means that pantothenic acid can help optimize the consumption of macronutrients as sources of energy during training.

*Pantothenic acid contributes to maintaining normal energy metabolism. Pantothenic acid contributes to reducing feelings of fatigue and tiredness.

Vitamin B6 contributes to maintaining normal protein and glycogen metabolism. It also helps in the normal production of red blood cells. Vitamin B6 is involved in amino acid metabolism and red blood cell production. Adequate numbers of red blood cells are crucial for oxygen delivery to muscles, which is important for training performance. Vitamin B6 is also involved in the production of neurotransmitters, which contributes to reducing feelings of fatigue and tiredness*.

*Vitamin B6 contributes to maintaining normal protein and glycogen metabolism. Vitamin B6 helps in the normal production of red blood cells. Vitamin B6 contributes to reducing feelings of fatigue and tiredness.

* Creatine enhances physical performance for consecutive short, high-intensity workouts.
