Liquid I.V.: I.V. O’Clock

Liquid I.V. created the hydration category a decade ago, and it was time to make a big impression as the faster and better way to hydrate. So to kick off Summer, with days getting longer and a desire to pack them full of fun, we introduced I.V. O’CLOCK, the antidote to the 4 PM slump. As the afternoon wears on, our energy dips, largely due to hydration. So we set out to flip the script to turn afternoon fatigue into an afternoon refresh, and create a habit of hydration at 4PM. But why exactly 4PM? Because IV translates to four in roman numerals. Rebranding 4 o’clock to I.V. O’CLOCK creates the official time for some Liquid I.V. and your daily reminder to hydrate and power through the rest of your day. The experience marked the official kickoff of Liquid I.V.®’s Summer 2025 campaign, anchored in the insight that dehydration is a major culprit behind the afternoon energy crash. The Liquid I.V.® Hydration Multiplier® provides hydration faster than water alone for up to 4 hours, making it the perfect hydration solution for fighting off that late-afternoon dip. I.V. O’CLOCK was created in partnership with advertising agency Zambezi, with media by Scale by Zambezi. Liquid I.V. will continue to expand its reach this Summer with a media integration on Peacock’s hit series Love Island USA, which premiered on June 3.
