Trained to the hundredth of a second. Fueled at the cellular level.
LIFE FUEL™ every day for cell energy and recovery. CELL BOOSTER™ on race day for the moment that counts. No sugar, no crash.

Two products. One rhythm.
Energy is made in the cell. Every day.
A 400 m sprinter trains twice a day, most days of the week. That asks for energy that is there in the morning and still there in the afternoon. LIFE FUEL™ supports the energy production in the cell with NR, B-vitamins and magnesium, delivered with ABSORPTIX®.
Four ingredients. One job: energy in the cell.
Supports energy production in the cell
300 mg nicotinamide riboside (NR), a premium NAD+ precursor that helps maintain healthy NAD+ levels.
NAD+ precursor (NR)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 magnesiumSupports 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-complexKeeps 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.
Metabolic catalystsPowered 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.

One shot, 15 to 30 minutes before. Sharp when it counts.
CELL BOOSTER™ is the shot for a single moment: a race, a hard session, a long day. 80 mg of caffeine, NR, magnesium and L-citrulline in 25 ml. No sugar, so no crash after.

“The 400 m punishes every weakness. BRONN CELL BOOSTER™ helps me show up sharp: for training, for racing, for recovery.”
Details decide. At every level.

+ 1 shot
LIFE FUEL™: 2 in the morning, 2 in the afternoon. CELL BOOSTER™: one shot, 15 to 30 minutes before the moment.
What LIFE FUEL™ users say about their energy.
“Since I started taking this I no longer have an afternoon dip. Great stuff.”
“After 10 months of extreme, persistent fatigue, despite a lot of sleep, both at night and during the day, I clearly noticed fewer energy dips from week 4. After 8 to 10 weeks I no longer needed my daytime naps, and even in the evening I have energy left. What a difference!”
“One month later and I notice I fall asleep much more easily and wake up more rested in the morning.”

LIFE FUEL™ as a monthly routine, with CELL BOOSTER™ for the days that ask more.
Your questions about the routine, answered.
Do I need to be an athlete for this?
No. Liemarvin trains twice a day, 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, whether that is a race or a big meeting.
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 free CELL BOOSTER™ work?
Start a LIFE FUEL™ subscription and a CELL BOOSTER™ 6-pack (worth €24,40) is added to your cart at €0, automatically, with your first delivery. No code, nothing to remember. CELL BOOSTER™ is our liquid shot for days that ask a bit more: a meeting, a workout, a long drive.
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.
