A pharmacist does not ask how much you take. He asks how much arrives.

Christophe Bouvry evaluates supplements the way a pharmacist evaluates any active: not by the milligrams on the label, but by the form, the dose and the delivery, because that is what decides how much of it your body can actually use. LIFE FUEL™ is the formula he built on that principle: bio-active B-vitamins, magnesium bisglycinate and a NAD+ precursor, engineered with ABSORPTIX® to reach the cell.

Why I co-founded BRONN
“In pharmacy, an active ingredient is only as good as its delivery system.”

“I joined BRONN because their commitment to superior bioavailability sets a new benchmark in the industry. With LIFE FUEL™ we don't just follow trends: we select high-purity precursors and essential co-factors that work in synergy, and with ABSORPTIX® we make sure they don't just look good on a label, but actually arrive where they are needed.”

The three checks

What a pharmacist checks before he looks at the claims.

Three questions Christophe Bouvry asks of any supplement, and where most fall short:

  • Form. Cyanocobalamin, pyridoxine and folic acid have to be converted before the body can use them, and part of that conversion fails. LIFE FUEL™ uses methylcobalamin, P5P and 5-MTHF: the forms your cells use directly.
  • Dose. A ‘complex’ with a few milligrams looks complete on a box and does little. LIFE FUEL™ states every dose per capsule: 300 mg NR, 1389 mg magnesium bisglycinate, B-vitamins at meaningful levels.
  • Delivery. Magnesium oxide is cheap and barely absorbed; bisglycinate is bound to an amino acid and taken up far better. And every active still has to survive stomach acid, the gut wall and the liver. That is what ABSORPTIX® is for.

Absorption is not a detail. It is the whole point.

The challenge

The digestive gauntlet.

Between intake and your cells, a supplement has to clear six biological barriers. Most do not. Even high-dose formulas deliver only a fraction of what is on the label.

The solution

Powered by ABSORPTIX®

Taking a supplement is not the same as absorbing it. ABSORPTIX® is BRONN's patented anti-competitive formulation logic: every ingredient gets its own transport route, plus the cellular energy to actually take it in. So nutrients do not just reach the liver. They reach the cell.

Form. Dose. Delivery.

How LIFE FUEL™ passes the three checks.

Form

Bio-active, no conversion needed.

Methylcobalamin (B12), P5P (B6), 5-MTHF (folate), riboflavin, nicotinamide. Magnesium as bisglycinate. NR as a direct NAD+ precursor.

Dose

Every dose on the label, per capsule.

300 mg NR · 1389 mg magnesium bisglycinate · B-vitamins at levels that contribute to normal energy-yielding metabolism. No proprietary blends.

Delivery

Protected and routed to the cell.

ABSORPTIX® keeps the actives from competing at the gut wall and shields them from stomach acid, so the dose on the label becomes a dose in the cell.

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

Bio-active B-vitamins (B2, B3, P5P, 5-MTHF, methylcobalamin) that your body can use directly, without conversion. They contribute to normal energy-yielding metabolism and the normal function of the nervous system.

Bio-active B-complex
03

Supports your biorhythm and recovery

Magnesium bisglycinate, a highly bio-available organic form. Magnesium contributes to the reduction of tiredness and fatigue and to normal psychological function.

04

Makes sure it actually arrives

ABSORPTIX®, our proprietary formulation logic developed by pharmacists, protects and delivers the active ingredients so they reach the cellular level.

What to expect, and when

An honest timeline. Give your cells a few weeks.

Results vary from person to person. This is what we typically hear from LIFE FUEL™ users.

Week 1
Your B-vitamins and magnesium are replenished. Some people notice a calmer nervous system and steadier focus. No instant energy, that is not how it works.
Week 2-4
NAD+ and B-vitamins integrate. This is where most users notice fewer dips in the afternoon and a more even energy flow.
Month 2-3
Daily use supports your natural biorhythm: waking up more rested and no longer needing the weekend to recover.

How to take it

2 in the morning, 2 in the afternoon, with water. One pouch is 30 days.

★★★★★✓ Verifiziert

“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

Forms, doses and absorption, answered.

Why do the forms of the vitamins matter?

Because your body has to convert a synthetic vitamin before it can use it, and that step is not free. Part of the dose is lost, and in some people the conversion works poorly. Bio-active forms (methylcobalamin, P5P, 5-MTHF) skip that step, which is why a pharmacist looks at the form before the milligrams. B-vitamins contribute to normal energy-yielding metabolism and the normal function of the nervous system.

Why magnesium bisglycinate and not magnesium oxide?

Magnesium oxide is the cheapest form and one of the least absorbed. Bisglycinate is magnesium bound to the amino acid glycine, which the gut takes up far more efficiently and which is gentle on the stomach. Magnesium contributes to the reduction of tiredness and fatigue.

What does ABSORPTIX® actually do?

It is BRONN's patented formulation logic (BE 2026 / 7260), developed by pharmacists. Nutrients compete for the same uptake routes at the gut wall; ABSORPTIX® gives each active its own route and protects it against stomach acid on the way. The goal is simple: the dose on the label becomes a dose in the cell.

Who is Christophe Bouvry?

A pharmacist with expertise in pharmaceutical formulation and bioavailability, and co-founder of BRONN. He evaluates every BRONN formula through a clinical lens: not just the ingredients on the label, but the precision of their delivery and how well the body can actually use them.

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

It is not how much you take. It is how much your cells receive.
