Nicotinamide Riboside and Resveratrol in a single daily capsule. Designed to support cellular energy and the body’s own repair pathways.
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme involved in cellular energy production and in regulating sirtuins — a family of proteins linked to cellular repair. NAD+ levels naturally decline with age. The body cannot absorb NAD+ directly from a supplement, so we use precursors the body converts into NAD+.
Per daily serving:
Two capsules daily, with or without food. Consistency matters more than timing — NAD+ precursor research is dose-dependent, and benefits build over weeks of regular use.
Clinical studies have shown NR supplementation raises NAD+ levels in human blood. Whether higher NAD+ translates to specific subjective outcomes is still being studied. We won’t make longevity claims — those require decades of human data that don’t yet exist. What we can say: this formulation uses researched precursors at researched doses, and is the kind of supplement many people take as part of a long-term cellular-health protocol.
Every batch is tested for NR potency, trans-resveratrol isomer ratio, heavy metals, and microbial load. Certificates of analysis on request.

NMN is a naturally occurring compound found in trace amounts in foods including broccoli, avocado, and edamame. Supplemental doses are orders of magnitude higher than dietary intake and are required to meaningfully influence systemic NAD+ levels.
Resveratrol is a polyphenol found in red grapes and certain other plants. It is a known activator of SIRT1 — a NAD+-dependent sirtuin central to metabolic regulation and cellular stress response. The combination of an NAD+ precursor with a sirtuin activator is a logical pairing: NMN supports the availability of NAD+ for sirtuin function; resveratrol provides additional sirtuin-activating signalling.
Typical Dose: 250–500mg daily
NAD+ Capsules are taken in the morning. They form the foundation of the Cognitive Stack alongside Lion's Mane, and of the Full Protocol Stack alongside Creatine and Evening Recovery. Avoid taking late in the day NAD+ pathway activation has been associated with wakefulness and may interfere with sleep if taken close to bedtime.
What Is NAD+?
AD+ is a coenzyme found in every cell of the human body. It is essential to two fundamental biological processes: energy metabolism (as a key molecule in the mitochondrial electron transport chain) and DNA repair (as a substrate for PARP enzymes and sirtuins, which are proteins involved in cellular maintenance and longevity signalling).
The challenge is that NAD+ levels decline with age significantly. Research from the lab of David Sinclair at Harvard Medical School has shown that NAD+ levels in middle-aged mice are roughly half those of young mice. Human studies have confirmed similar age-related declines. This has generated substantial scientific and commercial interest in strategies to restore NAD+ levels.
Why Not Supplement NAD+ Directly?
NAD+ itself is not well absorbed when taken orally its molecular size prevents efficient transport across intestinal membranes. Instead, the most effective strategy is supplementing with precursor molecules that the body converts into NAD+ intracellularly. The two most researched precursors are NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside).
NMN vs NR What Is the Difference?
Both NMN and NR are precursors in the NAD+ biosynthesis pathway. NR is one step earlier in the pathway than NMN, meaning it requires an additional conversion step inside the cell. NMN, being one step closer to NAD+, has in theory a more direct route. Animal studies have consistently shown both to be effective at raising NAD+ levels. Human data, while more limited, is growing. A 2021 study in Cell Reports Medicine confirmed that oral NMN supplementation in men over 65 raised blood NAD+ levels significantly versus placebo.
Energy Metabolism and Mitochondrial Function
NAD+ is essential to the function of the mitochondrial electron transport chain the process by which cells produce ATP, their primary energy currency. Declining NAD+ levels are associated with reduced mitochondrial efficiency. Animal studies from the Sinclair lab have shown that restoring NAD+ levels via NMN reversed several age-related declines in mitochondrial function in aged mice.
DNA Repair
PARP enzymes which are heavily involved in detecting and repairing DNA strand breaks are NAD+-dependent. As NAD+ levels decline, so does the efficiency of this repair process. This is one of the proposed mechanisms linking NAD+ decline to the accelerated accumulation of cellular damage seen in ageing.
Sirtuin Activation
Sirtuins are a family of proteins involved in regulating cellular metabolism, stress response, and longevity pathways. They are NAD+-dependent they cannot function without adequate NAD+ availability. Sirtuin activity has been linked to caloric restriction benefits, mitochondrial biogenesis, and inflammatory regulation. Supporting NAD+ levels is one of the primary strategies for maintaining sirtuin function as we age.
Cognitive Health
NAD+ plays a role in neuronal energy metabolism and in the clearance of damaged proteins within brain cells. Preclinical models have shown that NMN and NR supplementation can improve cognitive performance in aged animals, reduce markers of neuroinflammation, and support synaptic plasticity. Human trials specifically investigating cognitive outcomes are currently underway.
Important Context
Much of the most compelling NAD+ research has been conducted in animal models, primarily mice. Human trials are ongoing but the body of human evidence, while promising, is still developing. This does not invalidate the science the mechanistic basis is well established but it is honest context that Lux Vita believes you should have.

Both NMN and NR (nicotinamide riboside) effectively raise NAD+ levels. NMN is one biosynthetic step closer to NAD+ than NR, requiring fewer conversion steps. Some research suggests NMN may have a direct transporter-mediated uptake pathway into cells, bypassing the need for dephosphorylation to NR before absorption. The Lux Vita formula uses NMN based on the current balance of evidence and the emerging human trial data supporting its efficacy.
Typical Dose: 250–500mg daily
NMN supplementation does not produce rapid, perceptible effects for most people. This is not a stimulant. Its mechanisms are foundational and cumulative. Users who experience benefits often describe gradual improvements in energy stability, mental clarity, and recovery over weeks to months. Some users notice no subjective change despite measurable increases in blood NAD+ levels. This is consistent with the research literature and is not a sign of non-efficacy.
