Why your package contains three pouches

Pouch 1 · free
Day 1 – 30

Top up

Every day 2 capsules in the morning and 2 in the afternoon. You top up your B vitamins and magnesium daily, which contribute to the reduction of tiredness and fatigue.*

LIFE FUEL™ builds up: what counts is taking it every day. For the moments you need to be sharp, there’s CELL BOOSTER™ in your package.

Pouch 2
Day 31 – 60

Keep going

Your routine runs on consistency. Take your capsules at the same moment every day, also at weekends and on busy days.

Briefly note how your afternoons go, so you can compare honestly later.

Pouch 3
Day 61 – 90

Your own rhythm

After three pouches you have an honest picture of how your routine runs and how it fits your day. Experiences vary from person to person.

After that, simply keep going: LIFE FUEL™ is a daily routine, not a course. With a subscription it continues automatically.

Why ABSORPTIX® makes the difference

Standard supplements lose a large part of their active ingredients in the digestive tract, due to stomach acid, poor solubility or competition between nutrients. ABSORPTIX® works with bioactive forms and smart combinations, so that NR, magnesium and the B vitamins are absorbed efficiently.

The comparison

Not just another daily supplement.

How LIFE FUEL™ differs from a regular multivitamin or magnesium supplement, which many people take daily for more energy or better sleep.

LIFE FUEL™Multivitamin or magnesium
How it worksNR, the precursor of NAD+, together with bioactive B vitamins and magnesium for your energy metabolism*Separate vitamins or minerals, without NR
B vitaminsBioactiveP5P, 5-MTHF and methylcobalamin, no conversion stepMostly standard forms your body first has to convert
MagnesiumBisglycinateBound to an amino acid, 1389 mg per daily doseOften magnesium oxide, an inexpensive form
AbsorptionABSORPTIX®Formulated for absorption at the cellular levelRarely formulated for absorption
DoseFull dose1389 mg magnesium bisglycinate and 300 mg NR a day. That’s why it’s 4 capsules, spread over the dayOften a lower dose that fits in 1 tablet
DevelopmentDeveloped by doctors and pharmacists in Belgium, vegan capsulesQuality and origin vary greatly by brand

*B vitamins and magnesium contribute to normal energy-yielding metabolism and to the reduction of tiredness and fatigue. General comparison with common multivitamin and magnesium supplements, based on typical formulations. Not a comparison with specific brands.

Frequently asked questions

Your LIFE FUEL™ 2+1 + CELL BOOSTER™ questions, answered

Everything you need to know about the package, LIFE FUEL™ and CELL BOOSTER™.

Have a question about a specific topic? Contact us
What’s in LIFE FUEL™ 2+1 + CELL BOOSTER™ 6-pack?
Three pouches of LIFE FUEL™ with 120 capsules each, each good for 30 days, and a CELL BOOSTER™ 6-pack (worth €24,40). You pay €122,80, the price of two pouches: your first month and the CELL BOOSTER™ are free.
Do I need a discount code?
No. LIFE FUEL™ 2+1 + CELL BOOSTER™ is a single product in your cart with everything included. Nothing to add, nothing to remember.
Is this a subscription?
No. The package is a one-time order. Want to continue afterwards? You can, one pouch at a time or with the monthly subscription at 15% off.
How do I take LIFE FUEL™?
Four capsules a day: 2 in the morning and 2 in the afternoon, with water. One pouch lasts 30 days. Why four? 1389 mg magnesium bisglycinate and 300 mg NR don’t fit in one capsule, so the daily dose is spread over the day. LIFE FUEL™ builds up: consistent daily use is what counts.
How long should I take LIFE FUEL™?
We recommend at least 90 days to start, about three pouches. After that, simply keep going: your body uses NAD+ every day and levels naturally decline with age. Experiences vary from person to person.
And CELL BOOSTER™?
CELL BOOSTER™ is for the moments that ask more: before, during or after an effort, a long meeting or a drive. One 25 ml shot, Red Energy aroma. It contains caffeine (80 mg per shot). Take no more than one shot a day and not late in the evening.
Can I take LIFE FUEL™ with other supplements?
If you take medication, are pregnant or breastfeeding, or have other health concerns, please consult your doctor or pharmacist first.
What are the delivery times?
Belgium, the Netherlands and Luxembourg: order before 5 pm, delivered the next day. Other EU countries within 3 business days. Shipping is free.
Can I return it?
Absolutely. We offer a 30-day money-back guarantee. Not satisfied? Let us know within 30 days of your first order and we refund your purchase.
Most supplements never reach your cells. Ours are built to. Food supplements should not replace a varied, balanced diet and a healthy lifestyle.
