None of these electrolyte products provide a person with a substantial amount of electrolytes especially potassium which is the most important imo. Plus they are all pricey. I have moved away from these products. For longer rides I have gone with dissolving my high quality multi-vitamin in my trail drink. Never had a problem since. The good multi-vitamins have far more electrolytes in them than these products. Due to restrictions by the FDA, you are stuck with replenishing potassium by food intake. For longer rides I bring a couple of cups of non-fat yogurt. It is super high in potassium and tastes really good on the trail. I also bring some tomato juice sometimes. It is also very high in potassium and vitamin C and the acids that assist in energy processing.
I use both gels, picked by flavor available. I think they both work good for a hit of quick energy on the trail. I tried espresso flavored yesterday, can’t remember which brand it was, but it was one of the two. It was nasty tasting….
