Energy drinks, minus the guesswork
Bloomday started with a fridge full of cans that all said 'energy' and very few that said how much. So we made our own.

Made in the Mile High City
We’re a small team in Denver who drink a lot of cans: at desks, on long drives, at the trailhead at 6am. We wanted something that tasted like real fruit, skipped the sugar and the sucralose, and told us plainly how much caffeine we were about to drink.
That last part turned into the whole idea. Every Bloomday can has its caffeine amount on it, and we make three levels: a full charge of 160 mg, a half charge of 80 mg, and a caffeine-free stick for when you’re done for the day. Pick the one that fits the moment, not the one that happens to be in the fridge.
Our cans are filled for us by a co-packer in Colorado, and our drink-mix sticks are blended and packed in the USA. Everything ships from our warehouse in Denver.
Four rules for every can
The number on the label
Every can and stick says exactly how much caffeine is inside, in big type. No proprietary energy blends, no guessing.
Zero sugar, no fake stuff
Sweetened with allulose and monk fruit. No sucralose, aspartame, artificial colors or artificial flavors.
Electrolytes in every can
Sodium, potassium and magnesium in the same amounts across the line, so the can you grab before a hike is the one you grab at your desk.
Pick your charge
160 mg, 80 mg or none at all. Choose the amount that fits the moment instead of drinking half a can and pouring out the rest.

Cans, sticks and less shipping weight
- Aluminum cans, which are widely recyclable at curbside in the US.
- Drink-mix sticks for travel: forty servings weigh less than two full cans.
- Paper-based shipping boxes and paper tape, no plastic air pillows.
