The Biological Age You Can Measure — And The Gummy Attia And Johnson Keep Referencing

Chronological age is 47. Biological age can be 41 or 53. The gap is largely mitochondrial.

There is a specific nutrient stack the longevity literature keeps returning to — NR, resveratrol, spermidine, CoQ10.

Biological age is not a metaphor. It is measurable. DNA methylation clocks, telomere length, mitochondrial function.

The core mechanism is the mitochondrion. NAD+ drops by more than 50% between 40 and 60.

The daily soft rose-pink gummy — where the rewind work quietly begins.

NR, resveratrol, spermidine, CoQ10 ubiquinol — the stack the Sinclair lab has been publishing on for a decade.

Chronological age is what your driver’s licence says. Biological age is what your mitochondria say. The gap is a nutrient story.

REWIND puts all four in a daily rose-pink gummy at meaningful doses. Premium priced ($68) — because the ingredients cost real money.

Week two energy stabilises, week four recovery improves, week eight the biological-age retest starts showing movement.

Macro of soft rose-pink REWIND gummies
Two gummies a day. The stack the literature actually uses.
By week three the change was quiet, then obvious. And then just — my normal. Which is when I actually knew REWIND was working.

The rewind stack, in one gummy

Four clinically-referenced ingredients at meaningful daily doses.

Nicotinamide Riboside (NR) — 300mg
The precursor form the mitochondrial-longevity literature centres on. Not niacinamide.
Resveratrol (trans-form) — 250mg
The sirtuin activator studied alongside NR in the Sinclair protocol.
Spermidine (wheat-germ) — 5mg
The autophagy-supporting compound with meaningful longevity data.
CoQ10 (ubiquinol) — 100mg
The mitochondrial fuel that declines steeply after 40.

Rated 4.9 by people who thought they had to live with it

By week three I noticed. It was subtle at first — then it was just my normal. That was the moment.
Rachel, 46 · Verified
I had quietly accepted this as my life for years. Eight weeks on REWIND and I quietly stopped accepting it.
Vanessa, 52 · Verified
My GP raised her eyebrows at the label. She said this was the first gummy she had seen with the actual doses.
