NAD+500 mg
Essential cellular coenzyme, studied for cellular aging. Research compound.
Lyophilized peptide · single vial
What it is
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every human cell. It carries electrons in redox reactions and is consumed as a substrate by sirtuins, PARP enzymes and CD38. Tissue levels decline with age, which is why it appears in metabolic and ageing research.

- Format
- Lyophilized powder
How it works
NAD+ is an essential cellular coenzyme whose levels decline with age, which makes it a focus of aging research.
Coenzyme
The cell's currency
NAD+ shuttles electrons in energy metabolism and is required by every mitochondrion to make ATP.
Sirtuins
Fuel for repair enzymes
Sirtuins and PARP enzymes consume NAD+ to regulate DNA repair and stress responses.
Aging
Declines over time
NAD+ levels fall measurably with age in research models, one reason the coenzyme is studied in longevity science.
Key benefits
- Longevity research focused on cellular repair and aging.
- Energy-metabolism protocols studying how cells produce and use energy.
- Studied as a foundational coenzyme, often part of a broader anti-aging plan.
Laboratory research only. Not for human or veterinary use.
What published research is studying
Mixed evidence base- Whole blood and tissue NAD+ concentrations after precursor supplementation (randomized trials)
- Skeletal muscle insulin sensitivity in postmenopausal women with prediabetes (10-week randomized trial)
- Systolic blood pressure and arterial stiffness in middle-aged and older adults
- Pharmacokinetics and clearance of directly infused NAD+ in humans
Most randomized human evidence covers oral NAD+ precursors rather than NAD+ itself; the only published human infusion study was a small pharmacokinetic pilot with no clinical endpoints.
Key research findings and references
Key research findings
In an 8-week randomized placebo-controlled trial in overweight adults, the NAD+ precursor nicotinamide riboside raised whole blood NAD+ by 22%, 51% and 142% across three dose levels.
Conze D et al., Sci Rep 2019In a 10-week randomized placebo-controlled trial in postmenopausal women with prediabetes, the NAD+ precursor nicotinamide mononucleotide increased insulin-stimulated glucose disposal.
Yoshino M et al., Science 2021 (NCT03151239)In a 2 x 6-week randomized crossover trial in healthy middle-aged and older adults, nicotinamide riboside was well tolerated and stimulated NAD+ metabolism.

Research handling
Full handling guide- 01
Lyophilized, sealed, batch-numbered
Each vial ships as a freeze-dried powder under an inert seal, tied to the batch on its Certificate of Analysis.
- 02
Store cold and dark
Unopened vials are kept refrigerated at 2-8°C away from light. Reconstituted material is stored refrigerated and used within the window the research plan defines.
- 03
Reconstitute with bacteriostatic water
The included bacteriostatic water is added slowly down the vial wall and the vial is swirled, never shaken.
- 04
Research use only
Supplied for laboratory research. Not for human or veterinary use. Handle with the personal protective equipment the laboratory requires.
Before you order
What ships in the box?
The vials selected, plus a free supply kit with every vial: one 3 ml bacteriostatic water, ten 0.5 ml syringes and ten alcohol swabs per vial, and the uu.life research handling card.
How does volume pricing work?
The price per vial depends on how many vials of the same strength are on the line. 3-4 vials take 5% off, 5 or more take 10% off. The discount is applied automatically and shows on the product page, in the cart and at checkout.
Is every batch tested?
Yes. Every batch is tested by an independent laboratory for identity and purity, and the Certificate of Analysis is linked from this page and the lab-testing library.
How fast is delivery?
Orders are typically dispatched within 1-2 business days and arrive across most of Europe in 3-5 business days, tracked, in discreet packaging. Orders over €250 ship free, and Shipping Protection can be added at checkout.
Is this for human use?
No. Every product is sold for laboratory research only and is not for human or veterinary use.
