For whom?

Pre-workout supplement with a unique composition of ingredients is intended for people who want to reduce the feeling of fatigue and tiredness before and during exercise and take care of the quality of their training, in particular:

  • physical performance,
  • muscle mass and strength,
  • energy metabolism,
  • post-training regeneration.

We would like to always be in great shape, resilient, full of energy, strength, and willingness to perform. Unfortunately, despite a healthy lifestyle, proper diet, and enough rest, we don’t always manage to give it our best. The same is true of physical activity. Sometimes fatigue and busyness effectively discourage us from going for a workout. If you train regularly and need a power boost before your scheduled exercises, supplementation can be a great support. Our Pre-workout sachets contain vitamins, minerals, amino acids, and plant extracts that will help you feel better before and during your workout, support its effectiveness, and recover after your workout. Achieve your training goals, improve your performance, and keep you in top shape!
Recharge your batteries in an easy and enjoyable way. The powder form and the ability to consume the supplement in a liquid makes life much easier for those who have difficulty swallowing capsules. In addition, the sachets are great for traveling.

The jA. line

The jA. line of products is a fresh look at the entire Levann Supplements brand concept. It’s more self-confidence and better awareness of one’s needs. Only by putting ourselves first and listening to our inner voice can we be 100% for others. Let’s take care of ourselves, get to know ourselves, feel good about ourselves, and live the way we like to live.

Ingredients for energizing yourself before your workout:

WATTS’UP® – orange fruit extract – bioactive hesperidin may be the missing element in your workout 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 an entire training (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, it helps muscles work more efficiently, resulting in 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)

Amino acids such as L-citrulline, L-Leucine, L-phenylalanine, L-Tyrosine, and Beta-Alanine – 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 produced. (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. (7)

Caffeine and taurine – 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.

Zinc**** – contributes to the maintenance of normal macronutrient metabolism, helps with normal protein synthesis, protection of cells from oxidative stress, and maintenance of normal testosterone levels in the blood. One of the most important aspects is its effect on the level of testosterone, a hormone essential for proper muscle growth and regeneration. Zinc also helps with the proper functioning of the immune system. It plays an important role in maintaining a healthy immune system, which can be compared to a fortress that fends off infections. It is what makes the body’s regeneration faster and more effective. In addition, zinc is beneficial for enzyme function, which is important for energy metabolism. This is because it optimizes biochemical processes, crucial for maintaining full energy and vitality.

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.

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.
