What’s happening
Reign Total Body Fuel has rolled out Watermelon Sour Gummy, a new flavor designed to hit that nostalgic “sour candy” profile while keeping the brand’s performance-first positioning intact.

What’s in the can
Reign is still doing Reign things here: high caffeine, zero sugar, and the same “functional energy” pitch the brand has used to compete in the performance category rather than the casual convenience lane.
Why this matters
Energy brands don’t just fight on formula anymore — they fight on flavor IP and repeatability. “Sour gummy” flavors have proven they can move units fast (especially in younger demo pockets), and watermelon is one of the safest high-volume flavor bets in the entire beverage world. Put those together and you’ve got a very obvious retail play.
