Product Information



Pre/Intra/Post Workout

The Future of Carbohydrates
Karbolyn® represents the dawn of a new era of carbohydrate supplementation. Unlike other carbohydrate sources, Karbolyn® is quickly absorbed into the bloodstream like a simple sugar but without the typical spike or crash caused when your muscles run out of fuel. In fact, Karbolyn® is a “homopolysaccharide” (relatively complex carbohydrate) that has been proven to be absorbed 18.21% faster (see chart below) than pure Dextrose (a simple carbohydrate), yet it still provides the sustained energy of complex carbohydrates.

Advanced Technology Makes Karbolyn® Superior to Other Carbohydrates
Carbohydrate sources such as unprocessed waxy maize starches are inferior for rapid glycogen loading and nutrient absorption. These starches have not been accurately processed to attain rapid absorption into the bloodstream. However, Karbolyn® uses a proprietary multi-stage “Enzymatic Milling Process” to reach optimal molecular size. This yields a superior carbohydrate for quick gastric emptying without any side-effects (such as stomach bloating or cramping) and is rapidly absorbed into the bloodstream.

Wow this is amazing!
Just bought this and wow it has made a huge difference i mix it into my post workout shake half a scoop which is 25G of carbs and it helps me with energy and kills my hunger until my next meal. This is a very high quality supplement and i will be using this everyday! I got the unflavored one and it has 0 taste so it goes really well with protein or BCAA if you prefer to use it intra workout overall i am very impressed with this! 10/10
