Recognise this?

Three signs your cells are asking for fuel, not more coffee.

01

Tired when the alarm goes

Seven hours of sleep, and still you wake up as if you had four. The first coffee is not a pleasure, it is a necessity.

02

Not as fresh as ten years ago

The same work, the same training, but it costs more and the recovery takes longer. Not a complaint, just an observation.

03

Energy that does not last the day

Fine in the morning, flat at three, and nothing left for the evening. Coffee and sugar move the dip; they do not remove it.

The mechanism

Waking up fresh starts in the cell.

1 · Where energy is made

Your cells make energy with NAD+.

Everything you do runs on energy your mitochondria produce. That production depends on NAD+, a molecule that declines with age: up to 65% between 30 and 70 (Massudi, 2012). Less NAD+, less energy, and a body that recovers more slowly.

2 · The base

NR, B-vitamins and magnesium. Every day.

300 mg NR as a NAD+ precursor, bio-active B-vitamins your body uses without conversion, and magnesium bisglycinate that contributes to the reduction of tiredness and fatigue. Four capsules, no caffeine.

3 · Why every day

Cell energy builds up over weeks, not hours.

Caffeine works in twenty minutes and is gone by the afternoon. LIFE FUEL™ works the other way around: nothing to feel at that moment, and a base that is there in the morning after a few weeks.

“Some mornings I used to get up thinking: I slept well, I am rested. And still I did not have that first energy for the day. That is why I started taking LIFE FUEL™, for that extra focus and above all the energy to get through the day.”

His routine

His day. Four capsules, one shot.

Morning · with breakfast

2 capsules LIFE FUEL™.

Before the first meeting or the first training. No caffeine, nothing to feel: the base for the day.

Afternoon · around 2 pm

2 capsules LIFE FUEL™.

The second half of the daily dose, before the moment the afternoon dip usually shows up.

Big moment · 15-30 min before

1 CELL BOOSTER™ shot.

For the days that ask more: 80 mg caffeine, NR and magnesium in 25 ml. Available as a 6-pack (€24,40).

How LIFE FUEL™ works

Four ingredients. One job: energy in the cell.

01

Supports energy production in the cell

300 mg nicotinamide riboside (NR), a premium NAD+ precursor that helps maintain healthy NAD+ levels.

NAD+ precursor (NR)
02

Reduces tiredness and fatigue

1389 mg magnesium bisglycinate, a highly bio-available organic form. Magnesium contributes to the reduction of tiredness and fatigue and to a normal energy-yielding metabolism.

Organic magnesium
03

Supports your nervous system

Bio-active B-matrix: P5P (B6), 5-MTHF (folate) and methylcobalamin (B12), forms your body uses without conversion. They support the normal function of the nervous system and psychological function.

Bio-active B-complex
04

Keeps the engine running

Riboflavin (B2) and nicotinamide (B3), the metabolic catalysts that contribute to normal energy-yielding metabolism and help protect cells from oxidative stress.

Powered by ABSORPTIX®

Taking a supplement is not the same as absorbing it. ABSORPTIX® is BRONN's patented formulation logic, developed by pharmacists: every ingredient gets its own uptake route and protection through stomach, gut and liver. So the dose on the label becomes a dose in the cell.

“Compared to a few years ago I need more sleep, more coffee and more rest. But I want to keep doing the same: the same training, the same work in the gym. The right supplements, like LIFE FUEL™, help me keep my schedule and still have the energy.”

Good to know

Your questions about the routine, answered.

Do I need to be an athlete for this?

No. Olivier trains most days, but the mechanism is the same for a long working day: your cells make the energy, and that production runs on NAD+, B-vitamins and magnesium. LIFE FUEL™ supports it daily; CELL BOOSTER™ is there for the moments that ask more.

Can I combine LIFE FUEL™ and CELL BOOSTER™?

Yes, that is exactly the routine on this page. LIFE FUEL™ contains no caffeine, CELL BOOSTER™ contains 80 mg per shot. Take max. one shot a day and not late in the evening.

How does the subscription work?

You get one LIFE FUEL™ pouch (120 capsules, 30 days) every month for €52,19 instead of €61,40: 15% off and free shipping. Cancel after month 2; swap, adjust or skip a month at any time. Prefer to try it first? One pouch is €61,40, no commitment.

When do I take LIFE FUEL™?

Four capsules a day with water: two in the morning and two in the afternoon. Consistency matters more than timing, so take it daily. One pouch of 120 capsules is a 30-day supply.

Is it safe for long-term use?

LIFE FUEL™ is a food supplement developed by Belgian pharmacists and notified with the Belgian FPS Public Health (NUT number). The ingredients (NR, B-vitamins, magnesium) are meant for daily, long-term use within the recommended dose. Pregnant or breastfeeding, or taking medication? Check with your doctor or pharmacist first.

What if I do not notice a difference?

Give it at least four weeks. Cell energy builds up gradually and most users notice the first change between week 2 and 4. That is exactly why LIFE FUEL™ works best as a monthly routine. Questions? Our team is one email away.
