GoodSport Hydration is a natural sports drink made by ultrafiltering milk to extract a broad spectrum of electrolytes, B vitamins, and carbohydrates while removing everything else — producing a clear, refreshing beverage with no artificial flavors, sweeteners, or dyes.

This Costco variety pack includes 15 individual 16.9 oz bottles across three flavors: 5 bottles of Fruit Punch, 5 of Lemon Lime, and 5 of Strawberry Lemonade. Each bottle delivers over 1,600mg of naturally sourced electrolytes — sodium, potassium, calcium, magnesium, phosphorus, and chloride — substantially more than leading sports drink brands. The formula is caffeine-free, contains 0g added sugar, and is enriched with B vitamins (B1, B2, B5, B6, and Biotin) to support energy metabolism. GoodSport is certified Non-GMO, gluten-free, and lactose-free, though it does contain a milk ingredient.

Supported by four peer-reviewed university studies, GoodSport has been shown to provide rapid fluid absorption and longer-lasting hydration than water and traditional sports drinks for up to four hours post-exercise. Its unique glucose-and-galactose carbohydrate blend accelerates fluid absorption and helps maintain stable blood sugar levels during physical activity.
