Longevity, honestly dosed
Nothing hidden in the bottle.
Every active declared in milligrams, at the dose the studies used. Third-party assayed, published per batch, and priced by the day so you can actually compare.

The range
Three families. One job each.
NAD+ runs the pathway. Longevity targets the mechanisms. Foundational fixes what is actually deficient. Most people need all three.

What are we solving?
Tell us the problem rather than the ingredient, and we will point you at the shortest route to it.
Energy
Mitochondrial output and the fatigue that arrives before any clinical marker does.
Cellular ageing
Senescent cell load, NAD+ decline and the repair machinery that slows with each decade.
Cognition
Focus, recall and the nerve growth factor pathways behind both.
Metabolic health
Glucose handling, insulin sensitivity and lipid profile.
Sleep & recovery
Sleep depth, nervous-system downshift and overnight repair.
Joint & muscle
Lean mass retention, connective tissue and the strength curve after forty.
Immunity
Immune resilience and the inflammatory tone underneath it.
Skin & hair
Dermal collagen density, elasticity and hair strength.

The four people come back for
Between them these account for a little over half of everything that leaves the lab.
The reference product
15% vitamin C, at the ratio the paper actually used.
NMN is one enzymatic step from NAD+, the coenzyme every cell uses to run energy metabolism and DNA repair. NAD+ levels fall measurably from the mid-thirties onward, and NMN is the most direct dietary route to raising them. We assay every batch for purity before it ships — with a compound this expensive, that is the only thing separating real material from filler.

Why we started
We could not find a supplement that would tell us what was actually in it.
Ingredient lists are ordered, not measured. A label can name the active you came for and carry a fraction of the dose it was studied at, and nothing on the label would tell you. So we built the range the other way round: pick one mechanism, dose it at the level the research used, and print the number.

The standard
Three rules we will not trade away.
None of this is proprietary. It is simply what a supplement should have been doing all along.
- 01
We print the dose
An ingredient list tells you what is in the capsule. It does not tell you how much. Every active is declared in milligrams, at the amount the studies actually used — not a sprinkle behind a blend name.
- 02
Tested, then released
Every batch is assayed by an independent lab before it ships, and a sealed sample is kept for three years so any claim can be re-tested. A brand that will not say how it checks its own material is asking you to take purity on faith.

Priced by the day
Pack sizes and serving counts differ wildly across this category, which makes headline prices useless for comparison. Everything here carries its cost per day, because that is the number worth comparing.

The range
Everything we make, by category
Start with what is actually deficient, then add the targeted work on top. Foundations first.
NAD+ Precursors
6The pathway itself
NAD+ falls with age in every tissue measured. These are the molecules the body converts into it — dosed at the levels used in published human trials, not at the levels that make a label look busy.
ShopNAD+ Support
3Methyl balance and cofactors
Running the NAD+ pathway hard consumes methyl groups and cofactors. This is what you take alongside a precursor so the pathway has the raw material to finish the job.
ShopCellular Health
3Senescence and mitophagy
Compounds studied for how ageing cells are cleared and how mitochondria are recycled. The newest and least settled part of the field, and priced as the actives genuinely cost.
ShopMetabolic
3Glucose and lipid handling
AMPK activators and insulin-sensitivity actives — the most clinically documented corner of longevity supplementation, and the one with the longest human record.
ShopAntioxidant
4Oxidative load, lowered
Polyphenols and thiols that act on oxidative stress and the inflammatory signalling that travels with it.
ShopCognitive
4Nerve growth and focus
Nootropic mushrooms and adaptogens, standardised to their active fraction so the dose on the label is the dose in the capsule.
ShopMinerals
2The deficiencies that are real
Chelated, bioavailable forms of the minerals population data actually shows people are short of. Unglamorous, cheap, and the first thing worth fixing.
ShopVitamins
3Measured, not guessed
Vitamins at doses supported by evidence, in the cofactor pairings that make them work — D3 with K2, never D3 alone.
ShopPerformance
2Strength and output
The handful of performance actives with genuinely large evidence bases. Creatine is the most studied supplement ingredient in existence; it belongs in a longevity range for the muscle and cognitive data, not the gym marketing.
ShopProtein & Structure
1Connective tissue
Collagen peptides and structural proteins at the molecular weights used in the trials that reported skin and joint outcomes.

What people say
We publish every verified review, including the ones telling us a product did not work for them.
- 5.0Rated 5 out of 5
“I had been taking NMN from three different brands and none of them would tell me the assay. This one publishes it against the batch code on the bottle.”
- 5.0Rated 5 out of 5
“The per-day price is the thing. I finally worked out I had been paying nearly double for the same berberine dose elsewhere.”
- 5.0Rated 5 out of 5
“Bought magnesium for years without realising oxide barely absorbs. The glycinate is a different thing entirely — I actually sleep through now.”
