CELL BOOSTER™ · for focus that lasts

Sharp when it counts. Without the crash after.

An energy drink hits your nervous system with sugar and 150 mg of caffeine, then drops you an hour later. CELL BOOSTER™ is built the other way round: a precise 80 mg of caffeine for alertness, NR and magnesium for the energy your cells make themselves, L-citrulline and taurine for flow. One 25 ml shot, 15 to 30 minutes before the moment that matters. Lime-ginger, no sugar.

Recognise this?

Three moments that ask for focus, not a kick.

01

The 2 pm presentation

Right after lunch, in the room where the decisions are made. You need a clear head for forty minutes, not a racing heart.

02

The workout after work

Legs are willing, head is still at the office. A pre-workout gives you the jitters; you just want to be present.

03

The deadline evening

Exam week, a report, a long drive home. Coffee number four is not the answer, and you know it.

The mechanism

Why a shot can be sharp and calm.

1 · Precision caffeine

80 mg. Enough to sharpen, not enough to shake.

Caffeine contributes to increased alertness and concentration. The dose makes the difference: 80 mg is roughly one good espresso, half of a typical energy drink. No sugar to spike and crash on top of it.

2 · Cell energy

NR and magnesium: the energy your cells make.

150 mg nicotinamide riboside (NR) helps maintain NAD+, the molecule your mitochondria use to produce energy. 100 mg organic magnesium contributes to the reduction of tiredness and fatigue. That is the part an energy drink does not have.

3 · Flow

L-citrulline and taurine, 3000 mg together.

A high-dose amino-acid matrix, plus 1000 mg L-carnitine that helps transport fatty acids into the mitochondria. Liquid, so it is absorbed fast, engineered with ABSORPTIX® for stability and uptake.

03

Keeps things flowing

Liquid, so it is fast

A 25 ml shot instead of a capsule to break down first. Formulated with ABSORPTIX® for stability and rapid uptake. Lime-ginger, no sugar, no artificial colours.

What to expect, and when

One shot. One moment.

Results vary from person to person. This is what we typically hear from CELL BOOSTER™ users.

15-30 min
Alertness and concentration come up. Take it before the moment, not during: a meeting, a workout, a drive.
During
Steady focus and muscle support while you work or train. No sugar wave, so no wave to fall off.
After
Magnesium and NR support recovery and cell energy, so the shot does not cost you the evening.

Good to know

Caffeine, timing and the packs, answered.

How much caffeine is in a shot?

80 mg per 25 ml shot, about one strong espresso and roughly half of a typical energy drink. Enough for alertness and concentration, low enough to keep your heart rate and your evening in order. Take max. one shot a day and avoid other caffeine late in the day. Not recommended for children, pregnant or breastfeeding women.

When do I take it?

15 to 30 minutes before the moment: a meeting, a workout, a long drive, a study session. Shake well and drink the whole shot. It works within half an hour and you will notice it for a few hours.

Is it an energy drink?

No. An energy drink is sugar plus a lot of caffeine in a big can. CELL BOOSTER™ is a 25 ml shot with a precise 80 mg of caffeine, no sugar, and actives an energy drink does not have: NR for NAD+, magnesium, L-citrulline, taurine and L-carnitine. It is engineered by pharmacists to support the energy your cells make, not just to push your nervous system.

Can I combine it with LIFE FUEL™?

Yes, that is how most of our users take it. LIFE FUEL™ is the daily base (four capsules a day, no caffeine) that builds cell energy over weeks. CELL BOOSTER™ is the shot for a single moment. Order three months of LIFE FUEL™ and a CELL BOOSTER™ 6-pack comes free.

How does the 10% on four packs work?

Add four 6-packs to your cart and the discount is applied automatically at checkout, no code needed. Prefer a fixed rhythm? The subscription sends one 6-pack a month at 15% off with free shipping, cancel after month 2.

The bottom line

Not a kick. Focus.
