Sleeping 8 hours and still waking up tired?
Then the problem is usually not your sleep, but your cell energy. LIFE FUEL™ supports it with a NAD+ precursor, bio-active B-vitamins and organic magnesium, delivered with ABSORPTIX®.
8 hours of sleep. Still tired.3 signs it is not your sleep.
Tired after 8 hours of sleep
You went to bed on time. You slept through. And still the morning feels heavy, as if the night did not count.
The 3 pm dip, every single day
Halfway through the afternoon the energy is gone. Another coffee helps for an hour, then the dip is back.
Your weekend goes to catching up on sleep
Saturday means sleeping in and a nap on the sofa. On Monday you are just as tired as on Friday.
Why more sleep is not the answer.
Sleep restores. Energy is made.
Sleep repairs your body, but it does not produce energy. That happens in your cells, in the mitochondria. If that production runs low, more sleep will not fix it.
NAD+ declines by up to 65% between 30 and 70.
NAD+ is the molecule your cells use to turn food into energy. It declines by up to 65% between your 30th and 70th year (Massudi, 2012). B-vitamins and magnesium are the cofactors that keep that process running.
Without absorption, nothing arrives.
A large part of standard supplements never reaches the cell. Stomach acid, the intestinal barrier and the liver take their share first. What is not absorbed cannot support your energy.
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.

What LIFE FUEL™ users say about their energy.
“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!”
“Since I started taking this I no longer have an afternoon dip. Great stuff.”
“One month later and I notice I fall asleep much more easily and wake up more rested in the morning.”

Frequently asked questions.
Is LIFE FUEL™ a sleep supplement?
No. A sleep supplement tries to make you sleep more or deeper. LIFE FUEL™ works on the other side of the equation: the energy your cells produce while you are awake. If you sleep enough and still feel tired, that is usually where the gap is. Some users do tell us they fall asleep more easily, which fits a steadier biorhythm.
When do I take it?
Four capsules a day with water: two in the morning and two in the afternoon, for energy and nervous system support throughout the day. Consistency matters more than timing, so take it daily. One pouch of 120 capsules is a 30-day supply.
Can I combine it with coffee?
Yes. LIFE FUEL™ contains no caffeine and no stimulants, so your morning coffee stays your morning coffee. Many users notice they need less of it in the afternoon, but that is up to you.
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. Started with a subscription? You can cancel from month 2 with a few clicks, no questions asked. And if something is unclear, our team is one email away.
