For the ones who don't slow down

Still training like you're 18?

You still push hard. Your body just needs more help to keep up and bounce back. That is where LIFE FUEL™ and CELL BOOSTER™ come in.

The shift

Same effort. Different recovery.

The eye-opener for me: you train just as hard as you always did, but your body asks for more support to recover.

  • Recovery takes longer than it used to
  • Energy dips show up sooner in the day
  • You want to hold on to what you have for as long as possible
  • And underneath it all: NAD+, the coenzyme behind cellular energy, declines as you get older

The goal was never to turn back the clock. It is to hold on to what you have, for as long as possible — and to give your body the support it now asks for.

The science

NAD+ does not wait for you to slow down.

NAD+ is the coenzyme your cells run on. Research in human tissue shows it declines steadily with age — which is exactly why the same training costs you more than it used to.

Schematic representation. Based on Massudi et al., PLoS ONE (2012), which measured NAD+ in human tissue and found levels drop by up to ~50% between the ages of 40 and 60.

LIFE FUEL™ and CELL BOOSTER™ both deliver NR, a direct NAD+ precursor, with ABSORPTIX® so your cells actually receive it.

BRONN · The science of delivery

Powered by ABSORPTIX®

Taking a supplement is not the same as absorbing it. ABSORPTIX® is BRONN's patented anti-competitive formulation logic: every ingredient gets its own transport route, plus the cellular energy to actually take it in. So nutrients do not just reach the liver. They reach the cell.
