High Molecular Weight Carbohydrate
Perhaps you haven't even heard of waxy maize starch? Or if you have, you're still not sure exactly what it is? Well, waxy maize is a very unique carbohydrate. It's a molecularly modified starch and is commonly referred to as a "high molecular weight" carbohydrate.
Waxy maize is specifically processed to deliver a molecular profile that is radically different from all other common carb sources, such as glucose, fructose, dextrose and maltodextrin. In case you don't already know, molecular weight is used to determine the size of molecules. Compared to other carb sources, the molecular weight of waxy maize is thousands of times greater! Although waxy maize is commonly processed from corn, it can also be made from a variety of other plant sources. Potatoes and barley are two of the other most popular sources from which waxy maize is derived.
Waxy maize has many benefits over other carb sources. Its high molecular weight minimizes its osmolality, which means how much water it pulls around each molecule. Since waxy maize has a low osmolality rate, it moves rapidly through the stomach. In fact, over twice as fast as other carbs!1 Other carbs commonly consumed post-workout, such as dextrose and maltodextrin, have a low molecular weight and therefore a high osmolality rate. This means they pass through the stomach very slowly and attract a lot of water, sort of acting like a sponge in the stomach. This is why both glucose and maltodextrin can cause stomach discomfort for some people. Since waxy maize rapidly empties from the stomach, it's delivered to the intestinal tract where it's quickly digested and absorbed. This rapid absorption provides a near instant boost in fuel to your blood and muscles and allows for rapid refueling during and after exercise, without bloating or any other negative side effects.
