Every FUEL POWER pouch contains 100mg of caffeine, and that's the only active ingredient in the formula. But what actually happens in your body between the moment you place a pouch and the moment you feel the boost? Here's a clear explanation, without unnecessary jargon.
1. The journey of caffeine through the body, step by step
Absorption
In an energy pouch, caffeine is absorbed through the oral mucosa (the gum and lip), a bit like some sublingual medications. This absorption route partly bypasses the digestive system, which explains why the effect is felt faster than with a coffee you swallow.
The peak in the bloodstream
Once in the bloodstream, caffeine gradually reaches the brain, where it acts on the central nervous system. How it feels depends heavily on individual sensitivity: some people feel a strong effect, others something much lighter.
Gradual elimination
The body then eliminates caffeine gradually, mainly via the liver. The time needed to eliminate half of the dose consumed varies a lot from person to person, depending on factors like metabolism or usual caffeine tolerance. This is one of the reasons why two people can feel the same 100mg dose very differently.
2. What caffeine actually does in the body
It blocks adenosine receptors
This is the central mechanism. Adenosine is a molecule that builds up in the brain throughout the day and sends a fatigue signal. Caffeine has a structure similar to adenosine: it binds to the same receptors without activating them. As a result, the fatigue signal is temporarily blocked, which gives that feeling of renewed alertness.
It stimulates the central nervous system
By blocking adenosine, caffeine lifts a natural brake on brain activity, which translates into a feeling of alertness and sometimes a short-term perceived improvement in concentration.
It acts on other systems in the body
Caffeine also has effects on the cardiovascular system (a slight increase in heart rate is possible) and can have a mild diuretic effect in some people. That's why it's recommended to stay mindful of hydration with regular consumption.
3. Why 100mg, and what does that actually mean?
100mg of caffeine falls roughly within the same range as a classic filter coffee. It's a notable dose, worth factoring into your total daily caffeine intake, across all sources (coffee, tea, sodas, other supplements).
4. A deliberately simple formula
FUEL POWER made the choice not to stack up active ingredients: each pouch contains only caffeine, at a fixed, known dose of 100mg, with no other active ingredient added. The goal is transparency: you know exactly what you're consuming, and how much, with every pouch.
5. Best practices to enjoy the effects without discomfort
Adjust the dose to your sensitivity
If you don't yet know your sensitivity to caffeine, be especially careful with a 100mg dose per pouch, and avoid using several pouches in quick succession within the same hour.
Choose the right moment
Avoid consuming caffeine, whatever the source, too late in the afternoon or evening, so it doesn't disrupt your ability to fall asleep.
Stay hydrated
Like any stimulant, caffeine is best paired with good hydration throughout the day.

Caffeine works on well-documented biological mechanisms: it blocks fatigue signals and stimulates alertness. With 100mg per pouch and no other active ingredient in the formula, FUEL POWER bets on simplicity and transparency rather than piling up ingredients. As with any source of caffeine, listening to your own sensitivity remains the best compass.
FAQ
