His routine

Two products. One rhythm.

Every day · morning and afternoon

LIFE FUEL™: the base.

4 capsules a day (2 + 2). A NAD+ precursor, bio-active B-vitamins and organic magnesium for cell energy and recovery. No caffeine.

Race day · 15-30 min before

CELL BOOSTER™: the moment.

One 25 ml shot: a precise 80 mg of caffeine for alertness, NR and magnesium for cell energy, L-citrulline for blood flow. No sugar.

Why both

Base plus boost.

LIFE FUEL™ builds over weeks, CELL BOOSTER™ works within the hour. Together they cover the daily routine and the day that asks more.

The base

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®.

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.

Metabolic catalysts
Plus

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.

The moment

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.

“Since I started taking this I no longer have an afternoon dip. Great stuff.”

Koen B. · reviews.io · verified

“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!”

Good to know

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.

The bottom line

Base every day. Boost when it counts.

LIFE FUEL™ for the daily base, CELL BOOSTER™ for the moment. Developed by Belgian pharmacists, delivered with ABSORPTIX®. Subscribe and get a CELL BOOSTER™ 6-pack free.
