e-Fuel Endurance Blend
First Endurance EFS

e-Fuel has nearly three times the complex carbohydrates (why is this important), and less than half the sugar compared to EFS. The increased level of complex carbs and lower sugar level in e-Fuel allows it to deliver significantly more energy than EFS, click here to learn why.

Nutrition Facts vs. Supplement Facts
When reading the EFS label you will notice that it lists "Supplement Facts" instead of the "Nutrition Facts" that you are accustom to seeing on food and drink labels. This is an important distinction. The Food and Drug Administration (FDA) maintains a list of food ingredients that they have tested and have determined to be "Generally Regarded as Safe" (GRAS). If a product uses ingredients that are on the GRAS list in quantities determined to be safe by the FDA then the product is considered a food and can be labeled with a Nutrition Facts label. However, if a product uses ingredients that are NOT generally regarded as safe or in quantities that have not been determined to be safe, then they are typically classified as supplements in which case they are labeled as such with a Supplement Facts label.

All ingredients in e-Fuel Endurance Blend are generally regarded as safe by the FDA and are disclosed on the Nutrition Facts label.

e-Fuel is Gluten FREE and contains NO artificial flavors, colors or sweeteners ... Just Clean Energy!

Maltodextrin is the preferred carbohydrate source for endurance athletes and as such it is the primary ingredient in e-Fuel as well as most other good products on the market. EFS is 67% simple sugars. The danger of high sugar content products such as Cytomax is that they can elevate your blood sugar level too far too fast which can lead to a sugar crash (also known as bonking). Higher sugar content also raises the osmolality of the product which can reduce energy delivery, delay fluid absorption and promote dehydration.

e-Fuel is designed to provide complete and balanced electrolyte replacement that is critical for proper hydration and to avoid muscle cramping. The sodium and potassium levels in e-Fuel are designed to meet the American College of Sports Medicine's recommendation for electrolyte replacement during intense athletic activity.
The Citrates in e-Fuel assist in the carbohydrate to energy conversion process as well as reduce and slow the build-up of lactic acid in your muscles.
e-Fuel is one of the few sports drinks on the market that contains antioxidant vitamins C and E to help protect against tissue damage, reduce soreness and aid in the recovery process. 



The nutritional information shown above for EFS is for an 8 oz serving as published August 2013. Please refer to the manufacturer's web site or product packaging for the most recent information.
