BodyArmor the US-based sports and functional hydration brand, is expanding its Flash I.V. line with the introduction of Flash I.V. Caffeine Zero Sugar, a new beverage aimed at active consumers seeking both hydration and alertness.

The latest release contains 95mg of caffeine, 2,290mg of electrolytes – more than traditional sports drinks – and zero sugar, positioning it at the intersection of the growing functional beverage and energy hydration segments.

It is offered in Pineapple Passionfruit and Watermelon Punch flavours, combining “bold taste with functional performance,” according to the company.

The move builds on BodyArmor’s broader Flash I.V. portfolio, which includes ready-to-drink beverages and hydration boosters, and reflects the brand’s strategy to target health-conscious, performance-oriented consumers.

The formulation also incorporates zinc and vitamins B and C, supporting immune health alongside hydration and cognitive alertness.

The launch follows the brand’s 2025 rebranding, which introduced a refreshed visual identity and packaging aimed at appealing to both established and next-generation athletes.

The functional hydration segment is experiencing rapid growth, driven by consumer interest in zero-sugar options, natural ingredients and beverages that combine hydration with cognitive or energy benefits.

The product officially launches today (January 14) and will be available nationwide in stores and online.
