A good economical package of energy gels with which you can get several hours of running. The taste is not particularly pleasant, I would recommend the mango flavor instead, and the boost it gives you is relatively short-lived. For a marathon, I needed to consume about one every half hour to 40 minutes. It's good to drink some water after consuming it. The most important thing is that it is easily digestible and, at least for me, I never needed to use the restroom after consuming it, which is crucial for runners.

One of the few gels that contain electrolytes in addition to carbohydrates, which helps to avoid carrying extra electrolytes with you. It contains approximately 85mg of sodium, 40mg of potassium, and 57mg of magnesium.
Personally, it didn't sit well in my stomach and caused some discomfort, even though I have been easily consuming the regular gels from high5 for years without any issues. Its composition is more liquid, which is probably why. In my opinion, even with this, you still need extra electrolytes. Give it a try and decide what suits you.
