Athletes and active individuals often consume large volumes of sports drinks, energy beverages, and electrolyte products as part of their training and recovery routines. These beverages — formulated primarily with water — carry whatever PFAS are present in their manufacturing water unless the producer specifically treats water for PFAS removal. For athletes already drinking higher volumes due to hydration requirements, beverage PFAS exposure can compound drinking water exposure in ways that are rarely considered.
Water as a Primary Beverage Ingredient
Sports drinks, energy drinks, and electrolyte beverages are essentially fortified water — their primary ingredient by volume and weight is water, with electrolytes, sugars, flavors, and functional ingredients added in relatively small proportions. This means that the PFAS content of the manufacturing water largely determines the PFAS content of the finished beverage.
Major beverage manufacturers typically use municipal water supplies and have water treatment systems to ensure product consistency. However, the sophistication of these treatment systems varies, and PFAS-specific treatment is not universally implemented. Studies of PFAS in packaged beverages have found variable levels depending on manufacturer location and water treatment practices.
Volume Amplification for Athletes
The heightened concern for athletes consuming sports beverages centers on volume. An endurance athlete training in a hot environment may consume 64–128 ounces of sports drink during a training session — two to four times the typical adult daily water intake. At the same PFAS concentration as tap water, this volume increase translates directly to proportionally higher PFAS intake from beverages alone.
Youth athletes in organized sports who receive large volumes of sports drinks during practices and games represent another vulnerable group — children face higher PFAS intake per kilogram body weight and have developing systems more susceptible to PFAS effects.
Manufacturing Water Quality and Brand Geography
Beverage manufacturing facilities are distributed across the United States and internationally, often selecting locations based on water quality, logistics, and economic factors. Facilities located in PFAS-contaminated areas face source water challenges that may or may not be adequately addressed by existing water treatment systems.
Major beverage companies have begun to acknowledge the importance of source water quality for PFAS management. Some have committed to PFAS testing of manufacturing water and finished beverages; others have not yet disclosed their testing practices or results. Consumer inquiries and advocacy for PFAS transparency in beverages represent an important driver for industry action.
Home Beverage Preparation
For athletes who prefer to mix their own sports drinks or electrolyte solutions — a common practice among performance-focused athletes using powdered electrolytes — using filtered water for preparation is a straightforward way to control PFAS exposure. Mixing electrolyte powder with reverse osmosis or certified carbon-filtered water eliminates the manufacturing water uncertainty and provides the hydration benefits without the PFAS concern.
The cost of home electrolyte formulation (electrolyte powder + filtered water) is typically lower per serving than commercial sports drinks, making this approach both health-protective and economical.
Regulatory Gap and Advocacy
No federal regulations currently require PFAS testing of sports drinks, energy beverages, or other packaged beverages sold in the United States. The FDA’s oversight of beverages under DSHEA and food safety regulations does not currently include PFAS-specific requirements. State-level action on PFAS in beverages is limited but emerging.
Advocacy through consumer organizations and sports nutrition professional associations for beverage industry PFAS disclosure and testing would accelerate transparency in this category. Athletes, coaches, and sports nutrition professionals are credible advocates for water and beverage quality standards that affect athletic populations.
