What is NAD+?

NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every cell of your body. It takes part in the processes that turn food into usable cellular energy.

NAD+ levels have been observed to decline with age in some human tissues, including skin and brain. Measurements in blood have been inconsistent, and the picture across the whole body is still being worked out.

Energy production

Helps convert the food you eat into usable cellular energy.

Genomic maintenance

NAD⁺ is a required substrate for PARP enzymes, part of the cell's normal DNA-maintenance machinery.

Cellular protection

Used by enzyme systems involved in the cell's normal handling of oxidative stress.

Cellular signalling

Sirtuins — a family of enzymes involved in metabolic regulation — depend on NAD⁺ to function.

The Library of Longevity · Field Note 01

We are living longer.We are not living better.

Over the last two decades, human life expectancy rose almost everywhere on earth. The number of years lived in good health did not keep pace. The difference between the two has a name, and it is getting wider.

12.4 years
The time the average American spends living with disease or disability at the end of life, as of 2019. It is the widest gap of any of the 183 World Health Organization member states studied.
9.6 years
The global average in 2019. It was 8.5 years in 2000. The gap is not closing.
78%
Share of American adults between 35 and 64 already living with at least one chronic condition.

Length is no longer the hard part. The years are being added. The open question is what condition they arrive in — and whether the last decade of a long life is spent living it or managing it.

That question is the whole reason this company exists.

Why α-KG

α-KG sits right where your cells use NAD⁺.So we built the formula around both.

  1. Food

    Nutrients from what you eat enter your cells.

  2. Your cells' energy cycle

    Inside every mitochondrion, the Krebs cycle processes those nutrients. α-KG is one of its steps, and NAD⁺ does its work on either side of it.

    α-KGNAD⁺
  3. Usable energy

    The result is energy your cells can spend.

Built around 1,360 mg of calcium α-KG, alongside the NAD⁺ precursors NMN and NR.

The Formula

Multiple ingredients. Distinct roles. One coordinated formula.

Four capsules, because 1,360 mg of alpha-ketoglutarate does not fit in two. Seven ingredients are declared at their exact amount per serving; the remaining three share a 470 mg blend.

Specimen Plate · No. 1

NMN

100 mg
Supports NAD+ metabolism*

A nucleotide the body makes from vitamin B3 and uses directly in NAD+ metabolism.*

Specimen Plate · No. 2

Nicotinamide Riboside

200 mg
Supports NAD+ metabolism*

A form of vitamin B3 that serves as a precursor to NAD+.*

Specimen Plate · No. 3

Calcium AKG

1,360 mg
Supports cellular metabolism*

A naturally occurring Krebs-cycle intermediate involved in normal energy-producing processes.*

Specimen Plate · No. 4

N-Acetyl Cysteine

200 mg
Supports antioxidant defenses*

Provides cysteine, which the body uses to produce glutathione — one of its most important natural antioxidants.*

Specimen Plate · No. 5

L-Arginine

200 mg
Nitric oxide building block

An amino acid the body uses to make nitric oxide, a signalling molecule.*

Specimen Plate · No. 6

What to expect

Your first 60 days.

What taking NAD+ Activator will look like once it launches, and what is going on in your body while you do.

  1. Day 1

    Start the ritual

    Four capsules with cold water after a meal. Your body takes up NR and NMN as raw material for making NAD⁺, and α-KG joins the energy cycle your cells already run. It is everyday biology, given its building blocks.*

  2. Weeks 1–4

    Keep it consistent

    Your cells don't stockpile NAD⁺. They use it and remake it all day, every day, so a steady daily routine matters more than any single dose. Tip: keep the bottle where you eat breakfast.*

  3. Day 30

    First bottle finished

    One bottle is 30 days: 120 capsules, four a day.

  4. Day 60

    Decide with confidence

    Two months is a fair trial for any daily supplement. At launch, every order will carry a 60-day money-back guarantee, opened bottles included.

Everyone is different, and we don't promise specific results. NAD+ Activator is a dietary supplement, not a treatment. *These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.

Common Questions

Before you begin

When can I order NAD+ Activator?

Not yet. NAD+ Activator is coming soon, and we aren't taking orders until launch. Join the launch list and we'll email you the day orders open.

How do I take NAD+ Activator?

For adults, take 4 capsules daily with cold water after meals. Each bottle contains 120 capsules — a full 30-day supply. See the label warnings before use.

What if it isn't right for me?

At launch, every order will be covered by a 60-day money-back guarantee, including opened bottles. Full terms will be published before orders open.

Where is it manufactured?

In the USA, from domestic and imported ingredients, in an SGS cGMP-certified facility. The facility's certification is published in the Library's Quality Records.

Why ten ingredients instead of one?

NAD⁺ doesn't work alone in the cell. Rather than relying on one ingredient, NAD+ Activator combines NAD⁺ precursors with calcium alpha-ketoglutarate and complementary nutrients, each with a distinct role.*

Are there any allergens?

Contains milk (from whey peptide). Other ingredients: veggie capsule, magnesium stearate, silicon dioxide, microcrystalline cellulose.

Why four capsules?

Volume. A serving delivers 1,360 mg of calcium alpha-ketoglutarate alone, and a capsule only holds so much. Four capsules is what it takes to deliver every amount on the label.

Will there be more than one size?

Yes. At launch there will be a 30-day supply (one bottle) and a 90-day supply (three bottles, priced lower per bottle). The formula is identical.
