Lack of energy can be caused by various factors, often independent of us. Most often, we feel overworked when we have a lot of responsibilities and we do not sleep. Fatigue also manifests when there is a lot of deficiency in the body, including iron, magnesium and vitamin B. We may feel unwell also when we have low blood pressure. However, there are supplements that will help us get back into shape and have more strength for new challenges.
Caffeine
Caffeine is very well known stimulant. You can find it in natural products in coffee beans and black tea. It very effectively counteracts fatigue and is extremely popular. It works on our body in several ways. First of all, it stimulates the nervous system to work. Stimulates vegetative centres - respiratory, vasomotor and vagus nerve, which is responsible for the balance. Thanks to that we have much better results during trainings. Significantly improves the work of the cerebral cortex, thanks to which we think faster, but also remember more easily. It also allows for much faster metabolism. This is because caffeine inhibits the breakdown of cAMP, which strengthens the thermogenic processes in the body. We burn a lot more fat with the same exercises. The heat in the body increases, which translates into faster burning of calories.
Tyrosine
Tyrosine is an amino acid that has countless important functions in our body. First of all, it’s found in proteins and is an important precursor of neurotransmitters - dopamine, noradrenaline and epinephrine. Thanks to it, we significantly increase our physical and mental capabilities. We are more focused and vital. It’s an amino acid that builds proteins and is endogenous, which means that our body naturally produces it. However, stress can cause it to definitely not be enough, so you should make sure you additionally supplement it. Tyrosine significantly improves brain function, thanks to which we think faster. We improve concentration and memory. We do not feel tired, but also unhealthily stimulated, because tyrosine does not raise blood pressure. We also have much more resistance to stress, which is very useful for people who work a lot. If we have problems falling asleep, tyrosine will also help us, because it significantly accelerates the production of melanin, responsible for healthy and deep sleep. It also reduces nervous tension and helps us relax.
It’s especially intended for heavily overworked people, which is why the athletes and those who are physically working will feel its action. However, its action is not only visible in the moments of severe fatigue, because people with thyroid problems should also take it. This is because tyrosine is used by the pancreas to produce thyroxine, which in turn triggers the synthesis of proteins, which has a positive effect on our metabolism. It also reduces the amount of bad cholesterol in the blood and stimulates the production of growth hormone, also called the hormone of youth. It affects faster recovery, but also increases muscle mass. For people who are trained in strength, it will be felt that the muscle strength and the muscle's ability to anaerobic contraction will be significantly improved, which is especially encountered in training with weights. Muscle endurance will also improve. Tyrosine also increases the release of dopamine, which helps in faster thinking and concentration, especially during training.
Guarana
Guarana primarily significantly accelerates fat burning, but it’s also an ideal source of natural caffeine and the world's richest source of purine alkaloids, which positively affect our concentration. Caffeine contained in it, however, is unusual because it significantly prolongs the action of catecholamines, which include adrenaline and norepinephrine. Thanks to this, we feel a significant increase in strength, but also a much greater concentration and concentration. It also helps to improve our training, which thanks to it’s much more effective. We feel less fatigue, but not at the expense of too high blood pressure. The body's efficiency is also significantly improved. Guarana has a very good effect on our brain. It helps in chronic fatigue and supports the body during very difficult training. It can also be helpful if you are studying for an important exam. It reduces stress and intensifies our vital forces. It’s also fully natural and safe for the stomach. It’s recommended especially to athletes.
