Welcome to Discount Carb Powders.  Where as proteins help with muscle rebuilding, carbs powders refuel and replenish. Of the various types of carb powders available, Waxy Maize Starch and Trehalose are two of the best. Waxy maize starches are long-chain, highly-branched, exceptionally-dense complex carbohydrates that are rapidly absorbed. Trehalose is a much smaller, slower-digesting molecule comprised of two unusually linked glucose sugars. Together, these carbohydrates provide intermediate energy, top-off glycogen stores, and aid with nutrient absorption ideal for pre workout supplements that also deliver pre workout energy.
