Nicotinamide adenine dinucleotide (NAD+) is a critical, ubiquitous coenzyme present in all living cells, serving as a principal electron carrier in redox reactions and a central hub of cellular metabolism.
In its oxidized form (NAD+), it acts as an essential co-substrate for key enzyme families—including sirtuins (SIRT1–7), poly(ADP-ribose) polymerases (PARPs), and CD38/CD157 ectoenzymes—linking its bioavailability to core processes such as energy metabolism, DNA repair, circadian rhythm regulation, and cellular stress response. Research-grade NAD+ is supplied as a high-purity, lyophilized or crystalline powder (typically β-NAD+, disodium salt) for controlled laboratory investigation into age-related NAD+ decline, mitochondrial dysfunction, and interventions targeting the NAD+/NADH ratio. This compound is intended strictly for in vitro and non-human in vivo research to elucidate biochemical pathways governing cellular aging, metabolic disease, and neuroprotection.
Complete Research Kit Contents & Verification
Each NAD+ order ships as a comprehensive experimental package designed for sensitive biochemical and metabolic research:

Research Applications & Scientific Utility
In laboratory environments, research-grade NAD+ enables investigation into foundational biochemical and metabolic pathways:
-
Sirtuin Research:
Study of SIRT1–7 activation and their roles in deacetylation, metabolic regulation, stress resistance, and longevity-associated signaling. -
Mitochondrial Function:
Evaluation of electron transport chain efficiency, ATP production, mitochondrial biogenesis, and NAD+-dependent metabolic flux. -
Aging & Senescence Models:
Research into NAD+ depletion as a hallmark of aging and testing of NAD+ repletion strategies in cellular and animal models. -
DNA Repair Studies:
Examination of PARP-mediated DNA repair mechanisms in response to genotoxic stress and their dependence on NAD+ availability. -
Metabolic Disease Research:
Exploration of NAD+ metabolism in models of obesity, type 2 diabetes, non-alcoholic fatty liver disease (NAFLD), and related metabolic disorders. -
Neurodegeneration Research:
Investigation of NAD+’s role in neuronal health, bioenergetics, and resilience in models of Alzheimer’s disease, Parkinson’s disease, and other neurodegenerative conditions.
Laboratory Handling & Safety Protocol – CRITICAL
-
Storage:
Store unopened vials at −20 °C or, ideally, −80 °C, protected from light and moisture. Stability is paramount. After reconstitution, aliquot immediately and store at −80 °C. Avoid repeated freeze–thaw cycles. -
Reconstitution:
Use ice-cold, sterile saline or the specified stabilization buffer. Work quickly on ice. Gently swirl to dissolve—do not vortex. The solution is highly unstable at room temperature and neutral pH. -
Light Sensitivity:
Perform all handling under low-light conditions. Use amber vials or wrap containers in foil for storage to prevent photodegradation. -
Laboratory Safety:
Standard PPE (lab coat, nitrile gloves, safety glasses) is required. While NAD+ is not highly toxic, it should be treated as a potent biochemical reagent and handled according to institutional safety SOPs.

Luke W. (Verified Buyer, Glasgow) –
Getting 500mg at this price point within the UK market without needing international freight is a major plus. High compound stability and straightforward checkout process.
Trevor L. (Verified Buyer, Sheffield) –
Appreciated having the CAS number, batch tracking, and storage temperature clearly printed on the secondary packaging. Very professional standard.
Michael C. (Verified Buyer, Oxford) –
Clear product descriptions and seamless card payment processing. Received my dispatch note and invoice almost immediately. Delivery took two working days.
Gordon H. (Verified Buyer, Edinburgh) –
The NAD+ quality is undeniable, and the cold-pack packaging was intact on arrival. The only small hiccup was the Royal Mail tracking link took 24 hours to go live, but it still arrived within the 48-hour window.
Sarah P. (Verified Buyer, Manchester) –
Ordered on a Tuesday morning and received it by Wednesday afternoon via tracked delivery. Really impressed with how fast the dispatch was for a UK supplier. Will definitely reorder.
Fiona K. (Verified Buyer, Cardiff) –
I accidentally entered an outdated postcode during checkout. Sent an email right away and customer service corrected the shipping label before it left the facility. Fantastic service.
Edward J. (Verified Buyer, Surrey) –
On my third order now from retatrutidecost.co.uk. Each 500mg NAD+ vial has shown consistent lyophilized cake structure with zero melting or degradation during transit.
Rachel B. (Verified Buyer, Leeds) –
Appreciate the attention to detail with the crimp seals and amber glass vial. Everything on retatrutidecost.co.uk arrived tamper-free, clean, and properly labeled.
