Longevity Support Pro™ pairs a monthly supply of both Happy Cells® flagship formulas.

SIGNAL provides 500 mg of β-nicotinamide mononucleotide, a precursor cells use to synthesize NAD+. REWIND provides 500 mg of nicotinamide adenine dinucleotide alongside 250 mg of quercetin and 150 mg of trans-resveratrol.*

Two formulas. One morning routine. $19.99 less than buying them separately.

Two formulas, one routine:

  • SIGNAL and REWIND taken together each morning. Three capsules total.

Four active compounds:

  • NMN 500 mg, NAD+ 500 mg, quercetin 250 mg, trans-resveratrol 150 mg.*

Measured in human trials:

  • A 2024 meta-analysis of 12 randomized controlled trials found oral NMN significantly raised blood NAD+ levels.*

Doses disclosed:

  • Every active dose printed on both labels. No proprietary blends.

What's Included

Two white supplement bottles from Happy Cells Research Labs displayed on a white pedestal against a dark blue abstract background. The larger bottle is labeled 'REWIND' and the smaller bottle is labeled 'SIGNAL'.

  • SIGNAL — NMN 500 mg*

    Beta-nicotinamide mononucleotide, a precursor cells use to synthesize NAD+ through the salvage pathway. One capsule daily.*

  • REWIND — NAD+, quercetin, trans-resveratrol*

    500 mg nicotinamide adenine dinucleotide with 250 mg quercetin and 150 mg trans-resveratrol standardized to 98%. Two capsules daily.*

  • Every dose on the label

    Four active compounds, four disclosed doses. No proprietary blends in either formula.

THE RITUAL

Three capsules. Every morning.

Take one SIGNAL capsule and two REWIND capsules together with 6-8 oz of water, with or without food.

The human trials behind these ingredients have run from 8 to 26 weeks.

How It Works

Two formulas, taken together.

SIGNAL provides NMN, the molecule cells use to synthesize NAD+ through the salvage pathway.*

REWIND provides NAD+ itself alongside quercetin and trans-resveratrol, two polyphenols studied in human trials.*

Both are taken in the morning as a single routine.

NMN and NAD+, Resveratrol supplement bottles side by side with longevity capsules in front of each of them.

The Research

The evidence

A 2024 meta-analysis of 12 randomized controlled trials covering 513 participants found a significant overall effect of oral NMN supplementation on blood NAD+ levels. (Zhang J, Poon ETC, Wong SHS. Crit Rev Food Sci Nutr 2025;65(22):4382-4400. PMID 39116016)

In a randomized, double-blind, placebo-controlled trial, 250 mg/day of NMN for 12 weeks in older adults produced significantly higher blood NAD+ and a significantly shorter 4-metre walking time versus placebo. (Morifuji M, Higashi S, Ebihara S, Nagata M. GeroScience 2024;46(5):4671-4688. PMID 38789831)

A 26-week randomized, double-blind, placebo-controlled trial in 46 healthy adults aged 50 to 75 studied resveratrol and quercetin taken together and reported improved memory retention and glucose metabolism. (Witte AV, Kerti L, Margulies DS, Floel A. J Neurosci 2014;34(23):7862-7870. PMID 24899709)

These studies tested the ingredients, not Longevity Support Pro.*

FAQ

What people ask about the protocol

  • One 30-day supply of SIGNAL (30 capsules, 500 mg NMN each) and one 30-day supply of REWIND (60 capsules, two per serving).

  • SIGNAL is $44.99 and REWIND is $54.99 separately, for a total of $99.98. Longevity Support Pro is $79.99, a saving of $19.99.

  • Three. One SIGNAL capsule and two REWIND capsules, taken together in the morning.

  • SIGNAL provides NMN, a precursor in the NAD+ salvage pathway. REWIND provides NAD+ alongside quercetin and trans-resveratrol. They contain different compounds and were formulated to be taken as one routine.

  • Yes. Both are typically taken in the morning, but splitting them across the day is also fine. Consistency matters more than timing.

  • The ingredients in both formulas have been studied in human trials without a consistent pattern of serious adverse effects.

  • Resveratrol may affect blood pressure, blood glucose, and platelet activity. Anyone taking anticoagulant, antihypertensive, or antidiabetic medication should consult a qualified healthcare professional. Neither formula has been studied in pregnancy or breastfeeding.

  • Yes. Protocol YEAR ONE provides a 12-month supply of both formulas in a single shipment.
