e-Gel
e-Gel is a complex carb based gel and very low in sugar (excellent for endurance athletes). A big selling point is also that it provides more electrolytes than any other gel and has a thin consistency that’s easy to get down and easy on the stomach.
Highlights and Advantages
Complex carbs (great for endurance), loaded with electrolytes, aminos and antioxidants, easy on stomach
Weaknesses
Not sold on Amazon (they sell direct) and no caffeine options if that’s important to you.
