THE RITUAL

One capsule. Every morning. For a year.

Take one capsule with 6-8 oz of water, with or without food.

Each bottle is a 30-day supply. Open the next one when the last runs out.

Why a Year

Consistency is the variable that matters.

The human trials behind NMN ran 8 to 12 weeks. Every one of them measured daily use over months, not occasional use.

The most common reason a supplement routine fails is that it runs out and does not get reordered.

SIGNAL YEAR ONE removes that failure point. The year is already on the shelf.

THE FORMULA

One active ingredient. No guessing.

β-Nicotinamide Mononucleotide (β-NMN) — 500mg
The direct cellular precursor to NAD+. This is the molecule researchers at Washington University School of Medicine, Harvard Medical School, and Keio University have studied in human trials.* No proprietary blend. No hidden dose. The full 500mg is listed in the name.

HPMC — Vegetable Capsule
Plant-derived, vegan. No gelatin, no animal byproducts.

Microcrystalline Cellulose · Silicon Dioxide · Magnesium Stearate
Standard functional excipients required for capsule manufacturing integrity. Included because the capsule needs them.

What you won't find:

Certifications:
Vegan · Gluten Free · Lactose Free · Allergen Free · Halal · Manufactured in a GMP-certified, FDA-registered facility in the USA.

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 multicenter dose-ranging trial in 80 healthy middle-aged adults tested 300, 600, and 900 mg daily for 60 days. All doses raised blood NAD+. (Yi L, Maier AB, Tao R, et al. GeroScience 2023. DOI 10.1007/s11357-022-00705-1)

These studies tested the ingredient, not SIGNAL YEAR ONE.*
