Legionarius

amamoto® Nutrition Legionarius is a food supplement made with isomaltulose Palatinose® and branched-chain amino acids (BCAAs) in a 2:1:1 ratio derived from plant fermentation, enriched with coconut water and electrolytes in citrate form.

The product is enriched with magnesium and potassium, which contribute to normal muscle function, and with vitamins B6 and B12, which—alongside magnesium—contribute to normal energy metabolism and help reduce tiredness and fatigue.

To maintain prolonged performance without physical or mental dips, athletes need constant energy support, while avoiding dehydration as much as possible. As always, Yamamoto® Nutrition’s mission is to develop highly effective products made from excellent raw materials, designed to meet the needs of athletes of all levels.

Thanks to close collaboration with professional athletes, continuous feedback, and the partnership between international MMA champion Alessio Sakara and Dr. Gabriele Trapani (Director of Research and Development at Yamamoto® Nutrition), we created Legionarius—a supplement designed to support the intense and prolonged training sessionstypical of fighters and athletes in combat sports, CrossFit, triathlon, marathon, cycling, and bodybuilding.

A professional athlete is a “holistic athlete”, heavily engaged in both aerobic and anaerobic effort, requiring a combination of responsiveness and endurance. He or she must sustain performance for long periods without energy crashes, mental fatigue, or digestive discomfort—and must recover as quickly as possible.

Legionarius is a Special Edition, developed based on the specific needs reported by a top-level athlete like Alessio Sakara. Our R&D department focused on the most critical issues that may arise during training or competition to create a product designed “by athletes, for athletes.”

Legionarius is a blend of ingredients to be consumed during training (mixed into a bottle or water flask), delivering a gradual wave of energy to support the muscles under stress, thanks to:

• Isomaltulose Palatinose® – a certified efficient carbohydrate
• Highly soluble BCAAs from plant fermentation
• Electrolytes in citrate form
• Coconut water

To achieve optimal energy performance during such a crucial phase, the athlete must consume high-quality, well-tolerated fuel.

Isomaltulose Palatinose®

Isomaltulose (Palatinose®) is a low-glycemic disaccharide sugar, composed of glucose and fructose. Naturally found in small amounts in honey and cane sugar, it has a sweetening power of about 45–50% compared to sucrose (table sugar). Recently, it has gained popularity in sports drinks due to its properties.

With a gradual absorption and release in the bloodstream, isomaltulose offers a moderate glycemic curve without spikes or sudden drops like those seen with glucose or maltodextrins. It is therefore a slow-release energy source that can sustain the body even during extended training sessions.

Due to its structure, it does not raise blood sugar or insulin levels excessively and does not cause gastrointestinal discomfort, such as fermentation, nausea, or osmotic diarrhea. It delivers stable energy and hydration thanks to its low osmolarity.

Branched-Chain Amino Acids (BCAAs)

BCAAs are widely appreciated by both strength and endurance athletes. They include three essential amino acids:

• Leucine
• Valine
• Isoleucine

These are essential nutrients the body cannot produce and must be obtained through diet. BCAAs are absorbed in the intestines and enter the bloodstream as free amino acids, bypassing the liver and being metabolized directly in muscle tissue.

Because they make up a large proportion of the essential amino acids in muscle, BCAAs help prevent muscle breakdown (catabolism) during training and are beneficial for both power and endurance sports, supporting muscles and delaying fatigue.

During prolonged, intense physical activity, muscle glycogen may become depleted, triggering an energy emergency. The body then begins to oxidize BCAAs from muscle proteins, which can compromise performance and recovery.

Mineral Salts, Electrolytes, Coconut Water

In addition to blood sugar balance, hydration is a key factor for athletes. Excessive fluid loss can severely impair performance and health. Losing more than 2% of body weight in fluids can significantly impact physiological function, causing:

• Increased physical and mental fatigue
• Higher body temperature
• Elevated heart rate due to decreased blood volume
• Greater glycogen consumption
• Altered metabolism
• Gastrointestinal issues
• Headaches
• Cognitive disturbances
• In extreme cases, collapse

Maintaining a good electrolyte balance before, during, and after exercise is crucial. Legionarius helps prevent dehydration thanks to a precise blend of:

• Electrolytes
• Magnesium
• Potassium
• Chloride

It also includes the natural rehydrating power of coconut water, rich in micronutrients that help prevent cramps caused by intense sweating or heat exposure.

Certified Quality Raw Materials

Yamamoto® Nutrition uses only certified and accredited raw materials. The ingredients are Grade A certified for the BRC Global Standard for Food Safety Issue 8 and are produced in Informed-Sport registered facilities.

Upon arrival in Italy, each batch undergoes rigorous quality testing before being used to produce the finished product, following strict manufacturing standards in Italian factories.

All products are also tested for potential allergens such as gluten and lactose.
