The 6 a.m. maths
You don't want coffee.You want the effect.
The cup
Queue, brew, wait. Six minutes gone before the first sip.
$6 a day on a cup you finish in the parking lot.
Bitter, hot, spillable — and nowhere to put it at the gym.
A sugar-and-syrup spike, then the 2pm dip.
The cube
Pop a cube. It melts in your mouth — no digestion delay.
Cents per serving, not dollars.
A blister strip fits in a pocket, glovebox or gym bag.
Stackable 50 mg doses with B-vitamins for a balanced lift.*
Three seconds, not six minutes
How it works
Pop a cube
Peel one cube out of the blister strip. No water, no cup, no cleanup.
Let it melt
Keep it in your mouth until it dissolves. Deep berry, cool finish — sugar free, zero calories.
Feel the lift
One cube carries the caffeine of about half a cup of coffee. Take two for a full cup.
Take 1 to 2 cubes as needed. Do not exceed 4 cubes in 3 to 4 hours.
Two ways to wake up
Same lift.Pick your taste.
Identical formula in both boxes — 50 mg natural caffeine, B3, B6 and B5, sugar free and zero calories. The only difference is the flavor you reach for.

My drive-thru habit is done
I keep a strip in the console. Two cubes at the on-ramp and I am sharp by the time I hit traffic. Saving about $25 a week.

Better than a pre-workout
No bloated pre-workout gut, no cold can. One lemon cube in the car park and my warm-up sets already feel better.

Gets me through the 3am wall
Break room coffee is undrinkable. I take one cube at 2:30am and it carries me to handover without the shaky feeling.

The lemon one wakes my mouth up
I bought both and the tangerine finish is my afternoon pick. I expected chalky vitamins — it is closer to a citrus mint.

Through security, into the meeting
No liquid, so it goes straight through airport security. I stopped hunting for a coffee shop in every terminal.

Weighs nothing in a pack
Twenty servings for the weight of a stick of gum. Lemon at the trailhead, another before the last climb.

Supplement facts · Blueberry Blast
50 mg of natural caffeine from green coffee bean — roughly half a cup of brewed coffee, or about the same as an espresso shot. Two cubes give you a full cup of coffee’s worth. Both flavors are dosed identically.
Take 1 to 2 cubes as needed. Do not exceed 4 cubes in 3 to 4 hours. For occasional use only, and not intended for anyone under 18 or sensitive to caffeine.
Only the taste. Blueberry Blast is deep and rounded with a cool coffee note; Lemon-Tangie Twist is sharp citrus with a tangerine finish. Same 50 mg natural caffeine, same B3, B6 and B5, same price.
Bright natural blueberry with a light coffee note on the finish. Sugar free and zero calories. Keep it in your mouth until it dissolves — no chewing needed.
Yes. Add a pack of each and they ship together in the same box. Free shipping still applies once your order passes $35.
Whenever you would reach for coffee: the commute, the pre-workout car park, the mid-afternoon dip or the start of a night shift. It is not a substitute for sleep.
Orders placed on a business day leave our facility within 24 hours. Free shipping on orders over $35, and every order is covered by our 30-day money-back guarantee.
