Dark Katana Carbo 525 grams YAMAMOTO

What is Dark Katana intra-workout and what is it used for?

Dark Katana is the intra-workout designed and developed for athletes who demand the most from every training session, to support intense and very high intensity workouts . It is a complete pre-workout, without the need for additives, in the form of an orange-flavored powder that, when dissolved in water, provides slow-release carbohydrates of the highest quality, essential amino acids, the next-generation Peptistrong™ peptide and a phyto-blend rich in natural extracts capable of working synergistically to support mental focus, reactivity and pump (green coffee, green tea tit. 40% EGCG, turmeric, sour cherry, blueberry, cavolo nero). The presence of quality carbohydrates, such as highly branched cyclic cyclodextrins and trehalose, make it ideal for supporting long-duration (>60 minutes) and high-intensity performances. The Dark Katana formula is complete and supports training from every point of view: it supports energy, reduces fatigue, supports recovery, hydration, correct plasma volume, supporting the muscle pump.

But what exactly does Dark Katana intra-workout contain to be so functional?

Dark Katana is an intra-workout composed of a complete and complex blend of ingredients and micronutrients, designed to act synergistically and support training to the maximum, especially when high intensity and long duration (>60 minutes):

• Highly Branched Cyclic Cyclodextrins (HBCD) : A cutting-edge carbohydrate designed to provide a sustained energy release to support athletic performance. HBCD provides rapid yet sustained energy, making it ideal for sports nutrition. Consuming these carbohydrates before exercise contributes to muscle glycogen stores and the maintenance of blood sugar levels. During performance, they provide energy, delay fatigue, and improve endurance during exercise. After exercise, they help replenish glycogen stores. Carbohydrate metabolism is involved in hormonal processes that promote the entry of nutrients, including amino acids, into muscle cells, accelerating muscle repair and growth. The highly branched structure of this high molecular weight carbohydrate improves the bioavailability of active ingredients, stability, and solubility (1; 2; 3);

• Trehalose : is a natural carbohydrate, a disaccharide sugar, formed by two glucose molecules. It is present in many living organisms and is used as an energy reserve and to protect proteins from damage. Trehalose has a lower sweetening power than table sugar (sucrose) and offers other advantages, such as greater thermal and acid stability. It is known to help induce a gradual increase in blood sugar levels, helping to avoid the energy drops typical of glycemic peaks, and is therefore functional in endurance and resistance sports, to support prolonged activity as an energy source (4; 5);

• L-leucine, L-citrulline, L-valine, L-isoleucine, L-threonine, L-lysine, L-methionine, L-phenylalanine, L-histidine and L-tryptophan: a mixture of essential amino acids to help meet protein needs, promoting energy support during performance and at the same time helping to reduce fatigue and counteract tiredness. (6);

• Hydrolyzed fava bean proteins PeptiStrong : A bioactive peptide derived from hydrolyzed fava bean protein that works through the M-TOR and Phospho-S6 signaling pathways to increase muscle synthesis, reduce muscle catabolism via the Atregin and MURF-1 pathways, increase mitochondrial mass, and optimize strength recovery. Hydrolyzed fava bean protein is a source of plant protein and is obtained through hydrolysis, a technique that breaks complex proteins into smaller peptides and amino acids, making them easier for the body to absorb. This manufacturing process makes the hydrolyzed proteins easily digestible. These specific cell-signaling peptides in PeptiStrong work intelligently using the body's natural signaling pathways to optimize cellular growth and recovery. Research on PeptiStrong suggests that these peptides contribute to increased muscle protein synthesis and energy, and reduced muscle breakdown and exercise-induced inflammation (7;8;9);

• Glycerol : functional molecule for cellular hydration and to help prevent the loss of water and liquids that occurs during intense training. For this reason, glycerol is used, especially in endurance sports, as a useful support for body rehydration and general improvement of performance (10);

• Sodium and Potassium : minerals in citrate form ideal for supporting hydration during intense and prolonged workouts and in case of excessive sweating to restore the correct electrolyte balance. Potassium helps regulate the flow of fluids in the cells, while sodium helps maintain the osmotic balance between the cells and the extracellular fluid (11);

• TruBeet : A patented and standardized formula high in natural nitrates extracted from beetroot ( Beta vulgaris ). The formula is standardized to contain over 6% inorganic nitrate (vs. traditional beetroot extracts, which typically contain 1-3%), allowing for significantly reduced dosages. It also harnesses the natural power of polyphenols, which work in harmony with nitrates to support exercise performance. Taking TruBeet facilitates the production of nitric oxide in tissues experiencing hypoxia, such as muscles during exercise. Improving the bioavailability of NO has been documented to influence muscle function and physical performance by reducing the cost of oxygen in ATP synthesis and increasing the recovery of muscle phosphocreatine (PCr) in hypoxic conditions. TruBeet® has been clinically proven to improve end-of-race performance in endurance events after prolonged, moderate-intensity exercise. The same study also found that TruBeet® can accelerate the kinetics of muscle deoxyhemoglobin, improving oxygen extraction from the muscles.(12);

• Magnesium : Magnesium is an essential building block for cells. It helps reduce tiredness and fatigue, maintain healthy bones and teeth. It contributes to the efficiency of the nervous system, psychological function and the muscular system (13);

• Blend of plant extracts: A combination of seven plant-based nitric oxide-boosting ingredients (Green Coffee, Green Tea, Turmeric, Cherries, Blueberries, Broccoli, and Kale) that have been shown in studies to fire up the body's nitric oxide production system. This blend is completely plant-based and nitrate-free, and is designed to help you experience the benefits of nitric oxide so you can focus on your performance. In several acute, double-blind studies, this blend has been shown to increase circulating blood nitric oxide levels for long-term support of the nitric oxide cycle (14);

• Vitamin B6: This B-complex vitamin plays a role in protein and glycogen metabolism, participates in the regulation of hormonal activity and the production of red blood cells. Furthermore, it plays an essential role in supporting the proper functioning of the immune system, stimulating cognitive functions and counteracting aging (15);

• Vitamin B1: Also known as Thiamine, vitamin B1 is primarily involved in carbohydrate metabolism: it plays a significant role in the process of converting glucose into energy (16).

Dark Katana is the perfect intra-workout supplement to support your workout in a comprehensive way: it provides energy and easy-to-use carbohydrates, fights fatigue, helps support muscle pump, counteracts catabolism, hydrates cells, and optimizes concentration and mental performance, all without impacting blood sugar levels or gastric emptying. It's an indispensable ally for getting the most out of your workout, especially during high-intensity workouts.
