I built UBurn because I needed it. Not a powder that promises miracles — a drink that actually holds you through the 4pm crash. Made with the same care I'd expect for myself.

It's not willpower

Every day, the same script.

10am
Morning control.

Coffee, focus, intentions set. You've got this.

3pm
The signal.

Blood sugar dips. Your body asks for sugar. It's biological — not character.

7pm
Willpower gone.

You over-eat dinner to make up for what the afternoon took. Guilt loops back.

The ritual

Three gestures. Four hours.

"My 4pm crash is gone."

I used to raid the snack drawer at 3:30 every single afternoon. Three weeks in, I genuinely forget. The taste is also way better than I expected.*

"Finally something that holds."

I tried so many "satiety" drinks. Most lasted 45 minutes max. This one actually carries me from 3pm to dinner. No coffee crash either.*

"My evenings changed."

I stopped over-eating dinner. The afternoons feel calm. I'm not white-knuckling it anymore. Recommending to my sister.*

FAQ

Common questions.

How does UBurn actually work?
Glucomannan, a soluble konjac fiber, forms a natural gel when it meets water in your stomach. EFSA recognizes this mechanism for satiety support within an energy-controlled diet. Result: you feel satisfied for up to 4 hours after one scoop.*
When will I notice a difference?
Most customers report satiety from the first scoop. For consistent control over afternoon cravings, 7-14 days of daily use produces the most reliable signal.*
Does it contain caffeine?
Zero caffeine. UBurn is built on plant fibers and natural actives — no jitters, no afternoon crash, drinkable any time of day.
How does it taste?
Hazelnut-vanilla notes. Smooth, naturally violet color from purple ube root. Mix with cold water, oat milk, or hot frothed milk depending on your moment.
Is it a meal replacement?
No. UBurn is a dietary supplement designed to support satiety alongside balanced meals — it does not replace meals. 30 kcal per scoop.
When does it ship to the US?
We ship from France within 24-48h after order. US delivery typically 5-8 business days. Free shipping on orders $40+.
