“Same start, same finish. That's what the routine gives me.”

Olivier Withofs · PGA Golf Professional
Why I take CELL BOOSTER™

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.

The ambassador's perspective

Why the on-demand shot earned a place in my bag.

Swipe to read

Some sessions don't allow for a slow build. Tournament rounds, lessons that need full focus, training blocks that decide a week's progress — those moments need a clean lift, not a stimulant crash. That's where CELL BOOSTER™ became part of the routine.

A clean lift, exactly when I need it. That's the difference.
Olivier Withofs · PGA Golf Professional

Liquid format, 15–30 minutes before the moment that matters. NR + L-Citrulline + 80mg precision-dosed caffeine. No crash, no jitter, no guessing. Just cellular energy that arrives when I need it.

Frequently asked

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.
