Twinlab MCT Fuel is a high-octane "human machine oil" containing emulsified medium-chain triglycerides (MCTs) and emulsified natural vitamin E. MCTs are lipids composed of medium-chain fatty acids. These unique lipids provide more than twice the energy power of carbohydrates and protein and are less likely to turn into body fat than are long chain fatty acids. MCTs are an alternative energy source which is readily utilizable and can reduce muscle protein breakdown. These are catabolic conditions where muscles breakdown exceed muscle growth. Similarly, prolonged, exhaustive exercise and dieting (restricting caloric intake) is also a catabolic state in which muscle protein is being broken down in order to provide metabolic energy. This would suggest that as an alternative energy source, MCTs may benefit some athletes and those athletes restricting carbohydrates and calories in the diet. Twinlab MCT Fuel is revolutionary new emulsified MCT (medium-chain triglyceride) oil that has been developed for quicker and easier assimilation and for those people who could never tolerate the taste of ordinary MCT oil. No chemical emulsifiers are used in MCT fuel. Only small amounts of natural lecithin and apple pectin, nature's natural emulsifiers are used in its production. MCT Fuel has a delicious, 100% natural orange flavor. It also does not have the undesirable oily taste like ordinary MCT oil. This product offers a "High-octane" energy boost. Many athletes have become accustomed to taking carbohydrate drinks to fuel themselves through a workout. But many bodybuilders follow low-carbohydrate, high-protein diets to accelerate fat burning and to remove excess fluid from tissue in order to get ripped with striated and well-defined muscles, ruling out the use of high carbohydrate drinks. MCT Fuel can be used as a quick-acting, highly concentrated energy source and alternative to high carbohydrate energy drinks for those bodybuilders on low-carbohydrate, high-protein diets.
