“A clean lift, exactly when I need it.” A PGA Pro's take on CELL BOOSTER™.
One liquid shot, 15–30 minutes before training or competition. A precision-dosed 6-ingredient performance matrix that gives me focus and systemic flow — without the sugar load or jittery crash.
What it actually feels like before a big moment.
One shot, 15–30 minutes before competition or a long training block. The lift is clean and quick: focus sharpens, blood flow comes up, the legs feel ready.
The 80 mg of caffeine is precision-dosed alongside 2000 mg L-Citrulline, Taurine, L-Carnitine and NR — a real performance matrix, not just stimulation.
Six ingredients. One precision-dosed performance shot.

Why the on-demand shot earned a place in my bag.
If you take one thing from this page, take CELL BOOSTER™.
“A liquid shot 15–30 minutes before a session and the cellular engine is ready when I am. Clean focus, real systemic flow, no sugar load and no jittery crash.”
Real results, verified reviews.
“CELL BOOSTER™ before a long training session is my new ritual. Focus stays sharper deeper into the work and I'm not hitting the wall after ninety minutes.”
“Switched from pre-workout drinks to CELL BOOSTER™ six weeks ago. Same focus, none of the jitters or stomach load.”
“Take one shot before training, focus stays sharp through the end. The 80 mg of caffeine is exactly the right dose — clean lift, no comedown.”
How Olivier uses CELL BOOSTER™.
One shot, taken at the right moment, makes the difference.
Before the session
One liquid shot, 15–30 minutes before training or competition. The cellular engine is primed by the time you start.
During the session
Focus stays clean. Blood-flow lift from L-Citrulline holds without the spike-and-crash pattern.
The result
Same start, same finish — that's the point. End-of-session output that doesn't drop off.
“The right shot at the right moment beats a stronger product taken at the wrong moment.”
Performance you can feel.

Common questions about BRONN supplements.
What is NAD+ and why does it matter for athletic performance? +
NAD+ is a coenzyme present in every cell — essential for cellular energy, DNA repair, and recovery. As we age, NAD+ levels decline, contributing to slower recovery and the dip athletes feel in the second half of long sessions. BRONN uses NR (nicotinamide riboside), a smaller precursor the body converts into NAD+ at the cellular level.
What is Absorptix® and how is it different from standard supplements? +
Absorptix® is BRONN's proprietary delivery protocol designed to address the six barriers between swallowing a supplement and cellular uptake. Instead of selling NAD+ directly (too large to absorb efficiently), BRONN uses NR with smart formulation, bio-active ingredients, and gastric acid protection to ensure nutrients reach the cellular level.
How does the subscription work and can I cancel? +
All supplements are available as a monthly subscription at 15% off with free shipping. You can swap, adjust quantities, or skip a month at any time. Cancellation is available after month two.
How and when should I take CELL BOOSTER™? +
One liquid shot, 15–30 minutes before training, competition, or any high-focus moment. Drink it straight from the bottle. The blend (2000 mg L-Citrulline, 1000 mg Taurine, 1000 mg L-Carnitine, 150 mg NR, 100 mg organic magnesium and 80 mg caffeine) is engineered to act fast and stay clean.
How long before I feel the difference? +
Most users notice improved focus and blood flow within 15–30 minutes of taking the shot. The lift stays steady through the session — no spike, no jittery edge, no crash.
Are BRONN supplements safe and officially registered? +
Every BRONN supplement is NUT-registered with the Belgian FPS Health. Each formula is reviewed by our panel of eight clinicians, including a pharmacist who gives the final sign-off.
