🧬 LIFE FUEL™ · four capsules a day, no caffeine · subscribe and save 15%, free shipping
Perform every day? It starts with the energy in your cells.
Performing day after day asks for a base, not a kick. LIFE FUEL™: NR, bio-active B-vitamins and organic magnesium, four capsules a day, no caffeine. The daily base of UFC fighter Alvi Dasuyev.

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

His daily base: LIFE FUEL™. Four capsules a day, two in the morning and two at noon. For the heaviest sessions, a CELL BOOSTER™ on top.
How LIFE FUEL™ refills the tank.
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.

An honest timeline. Give your cells a few weeks.

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.
