The Hydration Industry Doesn't Sell Water

The hydration supplement industry is not selling hydration—it is selling the idea that hydration is complicated.

Water stays out of this because water cannot be branded, cannot be venture-funded, cannot be differentiated. Water is a solved problem, which makes it worthless to anyone trying to extract recurring revenue from your morning routine.

The numbers are instructive. The global sports drink market hit $9. 2 billion in 2023 and is projected to reach $15 billion by 2030.

What shifted is messaging. In the 1980s, Gatorade was positioned precisely for athletes during activity. It was designed to replace electrolytes lost in sweat. That was honest marketing of a legitimate tool. By 2010, the category had sprawled—Powerade, Vitaminwater, Liquid IV, dozens of brands with different formulations and different target audiences spreading to office workers, gym-goers, hungover college students, anyone who could be convinced that plain water was inadequate.

Leon Festinger's research on social comparison showed that people evaluate their own abilities and opinions by comparing themselves to others. The hydration industry weaponized this. If athletes drink electrolyte beverages, then drinking plain water begins to feel like inadequacy rather than sufficiency—celebrity athletes in advertisements create a mirror you're supposed to recognize yourself in, even though you're not running a marathon in Tampa in August.

Here's what doesn't get said. For people doing normal things like working, exercising moderately, or existing in temperate conditions, water is sufficient. This is not controversial in exercise physiology. It is catastrophic for the business model. So the marketing move is subtle. Don't claim water is bad. Just make it seem like less than the baseline. Make optimization the baseline. Make sufficiency look like settling.

The question worth asking yourself isn't whether electrolyte drinks work. They do, in specific contexts. The question is whether you're in one of those contexts, or whether you're paying for the story instead of the solution.
