Recognise this?

Three moments that ask for a base, not a boost.

01

The second half of the day

The morning went fine. By the afternoon, or the evening training, the tank is empty. Not a lack of will, a lack of fuel.

02

The busy week that never ends

Work, training, family. You do everything right and still you are tired by three. Coffee borrows energy; it does not make any.

03

The long build-up

A training block, a marathon plan, a busy season at work. Consistency for weeks, not a kick for an hour. That asks for a base, not a boost.

Alvi & LIFE FUEL™

The mechanism

How LIFE FUEL™ refills the tank.

1 · Cell energy

NR: the NAD+ your cells make energy with.

300 mg nicotinamide riboside, a premium NAD+ precursor. NAD+ is the molecule your mitochondria use to turn food into energy, and it declines with age and load.

2 · Less fatigue

Magnesium and B-vitamins, in forms your body uses.

Magnesium bisglycinate and bio-active B-vitamins contribute to the reduction of tiredness and fatigue and to a normal energy-yielding metabolism. No conversion step.

3 · Every day

Four capsules. Two in the morning, two in the afternoon.

No caffeine, no stimulant. LIFE FUEL™ is the base that builds over weeks. Formulated with ABSORPTIX® 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

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.

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: a tank that is full in the morning and does not run empty by three.
Four LIFE FUEL™ capsules
4 caps
a day
How to take it

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

Good to know

Energy, caffeine and the routine, answered.

Is LIFE FUEL™ a stimulant?

No. It contains no caffeine and no stimulants. A stimulant borrows energy from your nervous system; LIFE FUEL™ supports the production of energy in your cells with a NAD+ precursor (NR), bio-active B-vitamins and organic magnesium. That is why there is no kick and no crash, and why it takes a few weeks to notice.

Does Alvi use LIFE FUEL™?

Yes. BRONN supports Alvi Dasuyev as an ambassador and supplies his routine: LIFE FUEL™ as the daily base and CELL BOOSTER™ for the heaviest sessions. Alvi does not give medical advice and makes no product claims.

Who is Alvi Dasuyev?

A Belgian professional MMA fighter, signed to the UFC, and a BRONN ambassador. BRONN supports his routine; he does not give medical advice.

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.

Are BRONN supplements officially registered?

Yes. Every BRONN supplement is NUT-registered with the Belgian FPS Public Health, developed by Belgian pharmacists and made in Belgium. They are food supplements, not a replacement for a varied diet. Pregnant or breastfeeding, or taking medication? Check with your doctor or pharmacist first.

How does the subscription work?

One delivery a month at 15% off with free shipping. Swap products, adjust quantities or skip a month whenever you want. Cancel after month 2.
