Known as a stimulant, caffeine is a nerve that belongs to the purine family. It occurs naturally in some food and beverage products, such as coffee, tea, cocoa, chocolate, guarana and energy drinks to which it is added. It is a molecule capable of actively interacting with the metabolism, stimulating the production of catecholamines. In its food form (as in coffee) it is less effective than when used in supplements, also due to the different dosage (on average, a cup of coffee contains about 80mg). For this reason, Caffeine is one of the most popular ergogenic and concentration-stimulating agents used and appreciated in sports. All athletes can benefit from its multiple effects, which are not limited to the stimulating effect on the central nervous system and maintaining focus during performance. This nerve substance can be a valid support for endurance activities, it can improve the perception of muscle contraction and increase pain tolerance during and after training. It is also important to remember its impact on thermogenesis: in fact, it is often included as a component in thermogenic supplements, the so-called "fat burners". Once absorbed, caffeine binds to adenosine receptors which, when stimulated by adenosine, lead to central sedation and relaxation. In this way it acts as a competitive antagonist, with a consequent increase in heart rate and blood perfusion, and a decisive increase in the state of alertness. This molecule is also capable of enhancing the activity of certain neurotransmitters, such as dopamine and acetylcholine for example. Dopamine significantly affects the level of concentration and mood, and increases the release of catecholamines through the sympathetic nervous system, thus stimulating the heart rate to increase, pushing more blood to the muscles and signaling the need for release by the liver of glucose in the bloodstream. For some time now, scientific research has presented us with numerous studies demonstrating the effects of oral caffeine intake on a biochemical and metabolic level in our body, which can be summarized in: increased heart rate, better oxidation of fatty acids, raised attention span and mental energy and raising the pain threshold.

What is CaffeineSUSTAINED RELEASE? is the new supplement of Yamamoto Nutrition's "gold" line, aimed at all athletes who want to benefit from the effects of caffeine added to those of an innovative production technology: microencapsulation. This technology allows the gradual release of the microencapsulated molecule, which exploits the lipid "carrier" transport to enhance and above all prolong the effects on the body without causing energy fluctuations and/or crashes. By assuming the more "traditional" forms of this substance, such as anhydrous caffeine (or coffee itself as a drink), we will have rapid absorption, with an equally rapid and transitory effect. The microencapsulation of caffeine in a lipid environment allows it to be effectively transported and rapidly absorbed, but to then be released into the bloodstream in a controlled and gradual manner, leaving no bad taste in the mouth even without the use of particular chemical additives. The endurance athlete, the fighter, or the body builder, looking for maximum performance in training, will be able to take CaffeineSUSTAINED RELEASE and guarantee the effects of caffeine prolonged over time (for four hours or more), without problems related to energy crashes. controllable, and ensure a substance that acts as a real buffer against fatigue. Our supplement therefore presents caffeine in a "new guise", capable of exploiting new vehicle technologies in favor of better performance and concentration during training, also allowing the effect of its thermogenic action to be exploited during the course of the day .

Benefits of our supplement Why take CaffeineSUSTAINED RELEASE:

• Stimulating effect on circulation;
• Increased cardiac output and systolic blood pressure;
• Increased muscle, kidney and skin blood flow;
• Increased metabolism and thermogenesis;
• Stimulating effect on the nervous system;
• Reduction of the sense of fatigue;
• No risk of energy crashes;
• Prolonged duration of effects thanks to microencapsulation technology.

How and when to take it Take 1-2 capsules a day with water. If integrated for its stimulating action, we recommend consuming it in the pre-workout, at least 30 minutes before the performance.
