Yamamoto® Nutrition Glycogen is a food supplement with highly branched cyclic dextrin, coconut water, potassium, flavonoids and magnesium. Use for intense and/or prolonged workouts, which are demanding for muscles and reduce glycogen in the muscle stores, and cause intense sweating. Highly branched cyclic dextrin is a highly water soluble carbohydrate, which is metabolized by the human body. After intense and / or prolonged workouts, with muscle fatigue and depletion of glycogen stores in skeletal muscles, metabolized carbohydrates contribute to the recovery of normal muscle function, i.e. contraction (see Directions). Moreover, potassium and magnesium contribute to normal muscle function; magnesium contributes to electrolyte balance and to reduction of tiredness and fatigue.
The most demanding athlete knows well the value of an effective food supplement combined with their daily meticulous food intake and in recent times, nutrition and supplements aimed at “periworkout”, that is before, during and after performance, have become one of the hottest topics. The “critical” moment for your preparation for the performance and subsequent recovery. In this regard, “intraworkout” drinks have become increasingly more important and more used. Until a few years ago, they were too likely to overload the digestive organism, taking away precious blood from the muscles, frequently causing gastrointestinal disorders or dips in blood glucose with the consequent obvious negative effects on training. The new intraworkout drink concept has overcome all these factors, allowing body builders, fighters, cross fitters as well as endurance sport athletes to take advantage of the difference that an effective supplement of precious elements can make. Yamamoto Nutrition was an innovator in Europe for this type of pre and post performance support supplement with the launch of special and specific elements such as cyclodextrins or various forms of hydrolyzate (Peptpro and Amizate) or Alani-l-glutamine ( Sustamine) and today presents another new “intraworkout” supplement based on highly branched cyclodextrins (Cluster Dextrins) with the addition of orange flavonoids (Watt’s up), coconut water powder, magnesium, potassium and sodium chloride citrates.
Cyclodextrins are now the most innovative form of carbohydrates to be taken during and / or after training, special glucose polymers that are derived from the reaction between amylopectin and a specific enzyme, forming a glucose polymer with a special cyclic structure that has exceptional use characteristics, an average molecular weight of 160,000 Da, very low osmolarity that favours very rapid gastric emptying and equally rapid absorption by the intestine which then gradually releases “ready to use” energy, all to the advantage of athletes who seek true performance support that aids the most efficient recovery. Cyclodextrins are the new generation carbohydrates that are more soluble and more rapidly absorbed than any other source, such as maltodextrin and dextrose. They have the added advantage of supplying more constant energy support over time, without spikes and the related “glycemic” crashes and without excessively raising insulin levels. This issue together with the limits resulting from gastrointestinal disorders have often been a great limiting factor in the use of carbohydrates during training. This is no longer the case today, thanks to all these characteristics, any athlete who is involved in particularly intense training, lasting a substantial period of time, will benefit from cyclodextrins, which were specifically created to sustain prolonged energy release, more constant blood sugar levels, with no disorders such as swelling, flatulence, nausea or osmotic diarrhoea.
When used as a post-workout supplement, cyclodextrins are precious elements that quickly restore the glycogen used for faster recovery.
Yamamoto® is always looking for innovative elements with proven effectiveness and, in Glycogen, we have found something new and interesting that can be added to cyclodextrins, namely WATTS’UP®, a flavonoid derived from sweet orange. WATTS’UP® is coming to the fore for its triple action that can be appreciated in all types of sports, from strength to endurance, thanks to its ability to make the action of the mitochondria, “our cellular power plant” more efficient, generating more ATPs at constant oxygen levels. It provides more aerobic endurance and more anaerobic power, and the most interesting thing is that all this is backed up by clinical studies in a prestigious scientific journal (Maastricht, The Netherlands, January 5th, 2018 Journal of Sports Science and Medicine).
Studies on this flavonoid show a clear increase in aerobic and anaerobic capacity / power in the athletes involved in the study through a direct improvement of mitochondrial activity. The dose contained in the single portion of Glycogen is sufficient to benefit from these positive effects of greater power and endurance. Watts’up has very high bio-availability and starts acting a few minutes after intake, so it finds excellent synergy with the rapid activity of the cyclodextrins, allowing maximum muscle performance over time.
Coconut water powder can be considered as a real pool of electrolytes with very high bio-availability. Its concentrated mineral salt content, including magnesium, potassium and calcium, aids maximum body hydration during physical activity and supports the body in times of intense effort and sweating without causing any gastrointestinal discomfort. To further support the best possible hydration for the body, counteract fatigue resulting from excessive fluid loss and the onset of cramps, Glycogen also contains potassium, magnesium, and sodium chloride citrates.
Glycogen is an intraworkout drink that is greatly effective in supporting performance lasting for medium and long periods of time. It provides guaranteed strong electrolyte support, with maximum tolerability and intestinal absorption capacity and is suitable for all athletes, including body builders, cross fitters, fighters and cyclists. It also lends itself to being further combined with other fast assimilating nutrients such as branched chain amino acids, essential amino acids or hydrolysed proteins to further boost recovery, by supplying rebuilding material to the muscles under stress or after effort.

Highly Branched Cyclic Dextrin Cluster Dextrin®
Citrus flavonoids WATT’S UP®
Ingredients: highly branched cyclic dextrin (Cluster Dextrin®), acid: citric acid; freeze-dried coconut water (Cocos nucifera L, fruit), potassium citrate, WATT’S UP® (flavonoids from Citrus sinensis (L.) Osbeck, fruit), magnesium citrate, sodium chloride, anti-caking agent: silicon dioxide; colour: carotenes; sweetener: sucralose.
Mix 2 scoops (30 g) in 300 ml of water and take once a day. To contribute to muscle recovery after very intense and/or prolonged workouts, consume carbohydrates from all sources at a total intake of 4 g per kg body weight (for example, for a 70 kg man the intake is 280 g), starting within 4 hours after training and ending no later than 6 hours after training. Drink adequately when working out.
WARNINGS: do not exceed the recommended daily dose. Food supplements should not be used as a substitute of a varied diet. A varied and balanced diet and a healthy lifestyle are important. Keep out of reach of young children. Keep in a cool and dry place, away from heat sources and sunlight. Do not dump after use
