 YAMAMOTO® NUTRITION Known as a stimulant substance, caffeine is a nerve agent belonging to the purine family. It occurs naturally in some food and drink products, such as coffee, tea, cocoa, chocolate, guarana and energy drinks to which it is added. It is a molecule that can actively interact with the metabolism, stimulating the production of catecholamines. In its dietary form (as in coffee) it is less effective than in supplements, partly because of the different dosage (on average, a cup of coffee contains about 80mg).
This is why 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 valuable support in endurance activities, 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: it is often included as a component in thermogenic, so-called 'fat-burning' supplements. 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, resulting in an increase in heart rate and blood perfusion, and a marked increase in alertness. This molecule is also capable of enhancing the activity of certain neurotransmitters, such as dopamine and acetylcholine. Dopamine significantly influences concentration level and mood, and increases the release of catecholamines via the sympathetic nervous system, thus stimulating an increased heart rate, pushing more blood to the muscles and signalling the need for the liver to release glucose into the circulatory stream. Scientific research has long presented us with numerous studies demonstrating the effects of oral caffeine intake on the body's biochemical and metabolic levels, which can be summarised as: increased heart rate, improved oxidation of fatty acids, increased attention threshold and mental energy, and increased pain threshold. What is CaffeineSUSTAINED RELEASE CaffeineSUSTAINED RELEASE is the new supplement from Yamamoto® Nutrition's "gold" line, aimed at all athletes who want to benefit from the effects of caffeine combined with those of an innovative production technology: microencapsulation. This technology allows the gradual release of the microencapsulated molecule, which exploits lipid 'carrier' transport to enhance and, above all, prolong the effects on the body without causing fluctuations and/or energy crashes. Taking the more 'traditional' forms of this substance, such as caffeine anhydrous (or coffee itself as a beverage), will result in rapid absorption, with an equally rapid and transient effect. The microencapsulation of caffeine in a lipid environment allows it to be efficiently transported and absorbed quickly, but then to be released into the circulatory stream in a controlled and gradual manner, leaving no bad taste in the mouth even without the use of special chemical additives. The endurance athlete, fighter or body builder looking for maximum performance in training will be able to take CaffeineSUSTAINED RELEASE and ensure the effects of caffeine are prolonged over time (for four hours or more), without problems related to energy crashes that are difficult to control, and ensure a substance that acts as a real buffer against fatigue. Our supplement therefore presents caffeine in a 'new guise', capable of harnessing new vehicle technologies for improved performance and concentration during training, while also allowing the effect of its thermogenic action to be exploited throughout 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 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 supplementing for its stimulating effect, we recommend consumption pre-workout, at least 30 minutes before performance.
