A Two reasons — #1 Ease of digestion and absorption, #2 simplicity of execution.

1. Ease of Digestion and Absorption: Isotonic solutions are essentially oral IVs. They’re the best way to take in nutrition with the least stress on the system. 

The issue with using multiple sources of nutrition is that, more often than not, the combination of all the “stuff” in your pocket will lead to overloading the gut. Yes, your body will eventually break down the nutrition in order to absorb it, but that will take time, energy, and fluid diverted from the bloodstream to do it. 

With an all-in-one liquid nutrition solution, you can ensure that the solution is already in an isotonic form as soon as you are ingesting it. 

1. Simplicity of Execution: We adhere to the K.I.S.S. (Keep it simple and stupid) method of fueling. Juggling gels, drinks, salt pills, bars, solid foods, etc. makes consistency with your nutrition virtually impossible to maintain. 

Not to mention, too much or too little can lead to bloating, dehydration, and the dreaded bonk. So rather than trying to perform a science experiment and find the right combination of “stuff” we put everything in one bottle. Simplicity is key.
