Carbogen
The Dual Nature of Carbogen
To understand the mechanisms of 'Carbogen', one must first delineate its two completely separate identities within the medical and nutritional sciences. In the realm of sports nutrition and dietary supplements, Carbogen® is a patented enzyme formulation (U.S. Patent No. 5,817,350) developed by Triarco Industries. In the realm of clinical medicine and respiratory therapy, Carbogen is a compressed medical gas mixture consisting of 95% Oxygen (O2) and 5% Carbon Dioxide (CO2). Both have distinct, highly specific biochemical mechanisms of action that serve entirely different physiological purposes.
Mechanism of Action: Carbogen® Enzyme Blend
The dietary supplement Carbogen® is engineered to optimize the digestion and utilization of complex carbohydrates. Carbohydrates are the primary fuel source for high-intensity athletic performance, stored in the muscles and liver as glycogen. While complex carbohydrates (polysaccharides like starches, cellulose, and hemicellulose) are preferred for their nutrient density, they place a significant digestive burden on the gastrointestinal tract. They must be enzymatically cleaved into monosaccharides and disaccharides before they can be absorbed across the intestinal epithelium.
Carbogen® facilitates this process through a synergistic blend of non-animal-derived, food-grade enzymes:
1. Amylase: This enzyme catalyzes the hydrolysis of alpha-1,4-glycosidic bonds in amylose and amylopectin, the two primary components of dietary starch. By cleaving these internal bonds, amylase rapidly reduces large, insoluble starch molecules into smaller, soluble oligosaccharides, maltotriose, and maltose. This pre-digestion reduces the time and energy the body must expend to access the caloric value of the carbohydrate.
2. Cellulase: Humans lack endogenous cellulase, meaning we cannot naturally break down the beta-1,4-glycosidic bonds found in cellulose, a primary structural component of plant cell walls. By introducing exogenous cellulase, Carbogen® breaks down these fibrous structures. This not only yields a small amount of additional fermentable substrate but, more importantly, degrades the cellular matrix of plant-based foods, liberating intracellular starches and nutrients that would otherwise pass undigested through the gastrointestinal tract.
3. Hemicellulase: Similar to cellulase, hemicellulase targets hemicellulose, a heteropolymer present alongside cellulose in plant cell walls. Breaking down hemicellulose further reduces the viscosity of the digestive chyme and enhances the accessibility of the primary starches to amylase.
Pharmacokinetics of Carbohydrate Release
The most critical biochemical feature of the Carbogen® enzyme blend is its impact on blood glucose pharmacokinetics. Typically, the rapid digestion of carbohydrates leads to a sharp, immediate spike in blood glucose, followed by a rapid compensatory insulin release, which can cause a subsequent hypoglycemic 'crash'. Laboratory tests demonstrate that Carbogen® alters this curve. When 200 mg of Carbogen® was added to cooked pasta, it efficiently broke the pasta down into amylopectin (60%) and maltose (15.9%) with only a 2.85% release of free glucose.
In vivo animal models further illustrate this mechanism. When dosed at 1 mg per gram of carbohydrate, Carbogen® produced a 20% increase in blood glucose levels compared to a placebo, but crucially, it resulted in a smooth, sustained decrease in glucose levels rather than a sharp decline. Peak glucose levels were achieved at 2 hours post-ingestion (approximately 225 mg/dL) compared to 1.5 hours in controls (approximately 150 mg/dL). This indicates that Carbogen® converts complex carbohydrates into soluble maltodextrins and oligosaccharides that provide a steady, prolonged release of energy, ideal for sustained athletic endurance.
Mechanism of Action: Carbogen Medical Gas
In clinical settings, Carbogen refers to a specific, regulated medical gas mixture (UN3156) containing 95% Oxygen (USP CAS: 7782-44-7) and 5% Carbon Dioxide (USP CAS: 124-38-9). The mechanism of action for this gas relies on the physiological principles of respiration and hemoglobin binding dynamics.
1. Hypercapnia-Induced Respiratory Drive: The primary driver of human respiration is not a lack of oxygen, but rather an accumulation of carbon dioxide. The 5% CO2 in the Carbogen mixture intentionally induces a mild state of hypercapnia (elevated CO2 in the blood). This is detected by central chemoreceptors in the medulla oblongata and peripheral chemoreceptors in the carotid and aortic bodies. The physiological response is a powerful stimulation of the respiratory center, leading to an increase in both the depth (tidal volume) and rate of respiration.
2. The Bohr Effect: Elevated carbon dioxide levels in the blood lead to a decrease in blood pH (respiratory acidosis) due to the conversion of CO2 and water into carbonic acid via carbonic anhydrase. According to the Bohr effect, a lower pH and higher concentration of CO2 decrease the affinity of hemoglobin for oxygen. Consequently, while the 95% oxygen in the Carbogen mixture heavily saturates the hemoglobin in the lungs, the 5% CO2 ensures that once the blood reaches the peripheral tissues, the hemoglobin more readily unloads its oxygen payload. This makes Carbogen gas highly effective at oxygenating hypoxic tissues.
3. Vasodilation: Carbon dioxide is a potent vasodilator, particularly in the cerebral vasculature. Inhaling Carbogen gas causes the blood vessels to dilate, increasing blood flow to tissues. This mechanism has historically been utilized in oncology to increase the oxygenation of solid tumors, making them more susceptible to radiation therapy, as well as in the treatment of sudden sensorineural hearing loss and central retinal artery occlusion.
In summary, whether acting as an enzymatic catalyst to optimize the sustained release of glucose from complex carbohydrates, or acting as a physiological modulator of respiration and hemoglobin affinity via inhalation, the term 'Carbogen' represents powerful biochemical tools for enhancing human performance and clinical outcomes.

Everything About Carbogen Article
Introduction to Carbogen
In the world of health, nutrition, and medicine, the term "Carbogen" is uniquely fascinating because it refers to two entirely different, yet highly impactful, interventions. For the endurance athlete, the bodybuilder, and the sports nutrition formulator, Carbogen® is a patented, specialized enzyme blend designed to unlock the true potential of dietary carbohydrates. For the medical professional, Carbogen is a life-saving respiratory gas mixture of oxygen and carbon dioxide.
This comprehensive guide will primarily focus on the sports nutrition application of the Carbogen® enzyme blend, exploring how it alters carbohydrate metabolism to fuel peak performance, while also providing crucial disambiguation regarding its medical gas namesake.
The Carbohydrate Conundrum in Sports Nutrition
Carbohydrates are the undisputed primary source of fuel for the human body during moderate to high-intensity exercise. When you consume carbohydrates, your body breaks them down into glucose, which is either used immediately for ATP production or stored in the muscles and liver as glycogen for future use. The importance of high-carbohydrate diets to promote glycogen storage in the days preceding an intense athletic event—a practice known as carb-loading—is a foundational principle of sports nutrition.
However, athletes face a physiological dilemma when choosing their carbohydrate sources. Foods rich in complex carbohydrates (like oats, brown rice, and whole-grain pasta) are preferred because they are nutrient-dense and provide a slower release of energy. But these complex carbs place a significant digestive burden on the gastrointestinal tract. The body must work hard to break down the complex polysaccharide chains into simple sugars. If an athlete consumes a large complex carbohydrate meal too close to an event, they risk gastrointestinal distress, bloating, and sluggishness as blood is diverted to the stomach for digestion rather than to the working muscles.
Conversely, simple sugars (like dextrose) are absorbed instantly, but they cause a rapid spike in blood glucose followed by a sharp insulin response, leading to a hypoglycemic "crash" mid-workout.
Enter Carbogen®: The Enzymatic Solution
To solve this dilemma, Triarco Industries developed Carbogen®, a patented enzyme formulation (U.S. Patent No. 5,817,350) consisting of a precise blend of non-animal-derived, food-grade enzymes: amylase, cellulase, and hemicellulase.
How the Enzymes Work
1. Amylase: This is the primary enzyme responsible for breaking down starches. It cleaves the bonds holding long carbohydrate chains together, reducing them to smaller, manageable pieces. 2. Cellulase and Hemicellulase: Humans do not naturally produce the enzymes required to break down plant fiber (cellulose and hemicellulose). By including these enzymes, Carbogen® breaks down the tough cell walls of plant-based carbohydrates, liberating the starches trapped inside that would otherwise go undigested.
The magic of Carbogen® lies in how it breaks these carbohydrates down. Laboratory tests have shown that Carbogen® efficiently increases carbohydrate release without causing a massive spike in free blood glucose. For example, when 200 mg of Carbogen® was added to cooked pasta, it broke the complex starches down primarily into amylopectin and maltose, with only a 2.85% release of pure glucose.
This means the carbohydrates are broken down enough to be easily absorbed and utilized, but not so much that they flood the bloodstream all at once. They are converted into soluble maltodextrins and oligosaccharides, which provide a steady, sustained drip of energy.
Clinical Evidence and Efficacy in Athletes
The theoretical biochemistry of Carbogen® is backed by both animal and human in vivo studies.
The Rat Studies: Sustained Glucose Release In vivo studies on rats demonstrated the pharmacokinetic power of Carbogen®. When dosed at 1 mg per gram of ingested carbohydrates, Carbogen® produced a 20% overall increase in blood glucose levels compared to a placebo. More importantly, researchers observed a smooth, gradual decrease in glucose levels in the dosed animals, compared to a sharp, rapid decline in the control group.
When added to a nutrition bar, Carbogen® significantly increased blood glucose levels over a five-hour period. Peak glucose levels in the Carbogen group hit approximately 225 mg/dL at the two-hour mark, whereas the control group peaked earlier at 1.5 hours with only 150 mg/dL. This proves that Carbogen® extends the window of available energy.
The Human Trial: University of Dayton To test if these sustained glucose levels translated to better athletic performance, researchers at the University of Dayton Human Performance Lab conducted a trial with five trained male cyclists.
After an overnight fast, the cyclists performed two 60-minute cycling bouts at 80% VO2 max, followed by an all-out sprint at 100% VO2 max. One hour prior to the bouts, they consumed a meal replacement bar with either 160 mg of Carbogen® or a placebo. The results, published in the International Journal of Sport Nutrition and Exercise Metabolism (2002), showed that glucose levels were consistently higher when Carbogen® was used. After 60 minutes of grueling exercise, the athletes taking Carbogen® had significantly higher blood glucose available to fuel their final sprint.
The "Other" Carbogen: Medical Gas Therapy
It is critical to address the other use of the word "Carbogen" to avoid confusion. If you search medical databases or pharmacy records (such as the FDA DailyMed or Drugs.com), you will find Carbogen listed as a prescription medical gas.
Medical Carbogen is a compressed gas mixture containing 95% Oxygen and 5% Carbon Dioxide. It is used exclusively in clinical settings via inhalation.
Why Inhale Carbon Dioxide? It seems counterintuitive to inhale CO2, a waste gas. However, the 5% CO2 in medical Carbogen serves a vital physiological purpose. Carbon dioxide is the primary trigger for the human respiratory drive. Inhaling it stimulates the brain to breathe deeper and faster. Furthermore, CO2 is a vasodilator (it widens blood vessels) and triggers the "Bohr effect," a physiological phenomenon where increased CO2 lowers blood pH, causing hemoglobin to release its oxygen more readily into the tissues.
Medical Carbogen is used to treat conditions requiring rapid tissue oxygenation, such as carbon monoxide poisoning, central retinal artery occlusion, and historically, to oxygenate solid tumors prior to radiation therapy in oncology.
Safety Warning: Medical Carbogen gas is a hazardous, highly pressurized oxidizer that can increase respiration and heart rate. It is strictly for medical use. Furthermore, as noted in respiratory guidelines, administering high-oxygen mixtures must be done with extreme caution in patients with Chronic Obstructive Pulmonary Disease (COPD), as their bodies rely on low oxygen (hypoxic drive) to trigger breathing, rather than high CO2.
Real-World Application and Dosing of Carbogen® Enzyme
Returning to the dietary supplement, how should athletes use Carbogen®?
Based on the clinical data, the standard effective dose of the Carbogen® enzyme blend is between 160 mg and 200 mg, taken alongside a carbohydrate-rich meal or meal replacement bar.
Timing: It should be consumed approximately 60 minutes prior to an endurance event or heavy training session. This allows the enzymes time to begin hydrolyzing the carbohydrates in the stomach, ensuring that peak glucose availability aligns with the middle and end of your workout (the 1.5 to 2-hour mark).
Product Confusion: Be aware of product naming conventions in the supplement industry. For example, products like "Skeleton Nutrition Karbogen 50" are carbohydrate and electrolyte powders designed to replenish glycogen. While they share a similar name and goal (carbohydrate fueling), they are providing the substrate (the carbs themselves), not necessarily the patented Triarco enzyme blend. Always read the supplement facts panel to see if you are buying carbohydrate powder or the amylase/cellulase/hemicellulase digestive enzyme.
Conclusion
Whether you are an endurance cyclist looking to avoid the mid-race bonk, or a bodybuilder trying to maximize the efficiency of your pre-workout oat meal without the bloating, the Carbogen® enzyme blend offers a scientifically validated solution. By intelligently breaking down complex carbohydrates into sustained-release energy, it allows athletes to fuel harder, longer, and more efficiently.
