LIFE FUEL™ · tired despite sleep

Tired after eight hours of sleep? The answer is often in your cells, not your bed.

Sleep restores, but it does not make energy. That happens in the cell, with NAD+, B-vitamins and magnesium. LIFE FUEL™ feeds exactly that. Four capsules a day, no caffeine.

Recognise this?

Three ways tired despite sleep shows up.

01

The alarm feels like an insult

Eight hours in bed, and you wake up as if you had four. The first hour of the day goes to getting started.

02

Sleeping in does not help

The weekend lie-in should fix it. It does not. Monday feels exactly like Friday.

03

Everything checked, nothing found

Blood values fine, iron fine, thyroid fine. And still the tank is never full.

The mechanism

Why sleep alone does not fill the tank.

1 · The engine

Energy is made in the mitochondria.

Every cell has its own power plants. They turn what you eat into ATP, the energy your muscles, brain and nerves actually run on. No stimulant can replace that production; it can only mask a shortage for a while.

2 · The fuel line

NAD+ declines by up to 65% between 30 and 70.

NAD+ is the molecule the mitochondria use to make ATP. It drops with age (Massudi, 2012). B-vitamins and magnesium are the cofactors that keep the line open. Less of them, less output.

3 · The delivery

Without absorption, nothing arrives.

A large part of a standard supplement never reaches the cell: stomach acid, the gut wall and the liver take their share first. Bio-active forms and ABSORPTIX® are there to get the actives where the engine is.

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

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.

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

“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!”

“One month later and I notice I fall asleep much more easily and wake up more rested in the morning.”

What to expect, and when

An honest timeline. That is why three pouches.

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 they wake up more rested and start the day faster.
Month 2-3
Daily use supports your natural biorhythm: easier to fall asleep, more rested in the morning, and an even energy flow during the day.

Good to know

Sleep, energy and the 3-pack, answered.

Does LIFE FUEL™ help me sleep?

LIFE FUEL™ is not a sleep aid and contains no sedatives. Magnesium contributes to a normal function of the nervous system and to the reduction of tiredness and fatigue. Many users tell us they fall asleep more easily and wake up more rested after a few weeks, which fits an even energy rhythm during the day. Results vary from person to person.

How do the free FUEL BOTTLE™ and CELL BOOSTER™ work?

Order three pouches of LIFE FUEL™ and the FUEL BOTTLE™ (worth €38,90) and a CELL BOOSTER™ 6-pack (worth €24,40) are included in the 3-pack bundle, at no extra cost. No code, nothing to remember. Together that is €63,30 in gifts.

What does BRONN-member mean?

Everyone who orders the 3-pack becomes a BRONN-member: you get invitations to our events and webinars with doctors and pharmacists, first access to new products and member-only offers. No extra cost, no subscription.

Why three pouches?

Cell energy builds up gradually. Most users notice the first change between week 2 and 4, and the real difference after two to three months. Three pouches is exactly that period, without running out halfway.

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

Rested in the morning. It can happen again.
