Product Details
- Performance 3x Quality Tested & Approved Dye Free Dietary Supplement Informed Sport - We Test, You Trust Banned Substance Tested Every Batch Karbolyn® Hybrid Performance Carb Endurance Gluten Free 50 g Karbolyn® Carbs Real Food Fast-Acting Fuel Zero Stimulants Zero Sugars Long Lasting Fuel ... Within Minutes! Derived from potato, rice and corn, Karbolyn® is a fast-acting, long-lasting, high-performance compound that offers the best of both simple and complex carbohydrates. Karbolyn® is absorbed into the bloodstream like a simple sugar but without the typical crash caused when your muscles run out of fuel. It has also been shown to be absorbed as quickly as pure Dextrose (a simple carbohydrate). Yet, it still provides sustained energy without crashing. Don't Take Our Word For It ... What Does The Study Say? The Clinical Study sought to document whether or not Karbolyn® has a positive and sustainable impact on blood sugar levels in normal adults during aerobic activity. Data obtained from participants indicated that a simple sugar promoted a steep drop and subsequent crash at a predictable point in time. Karbolyn® gave an overall smoother decline in blood glucose level. Our 3x Testing We don't cut corners! In order to know if a product meets label claim, it must be tested AND verified. Few supplement companies have the capability to test in-house, but at EFX Sports® we have an on-site lab that verifies ALL of our products are SPOT ON!
