If you’ve spent any time reading aboutlongevity science, you’ve encountered NAD+. It’s arguably the most talked-aboutmolecule in the aging research community — and for good reason. NAD+(nicotinamide adenine dinucleotide) is involved in hundreds of metabolicreactions in every cell of your body. Without adequate NAD+, your cells can’tproduce energy efficiently, repair damaged DNA, or activate the protectivepathways that keep aging in check.
The problem is that NAD+ levels plummet as youage. By middle age, most people have roughly half the NAD+ they had in theirtwenties. This decline is now understood to be a key driver of age-relateddisease and functional deterioration — not just a consequence of it.
Luvo’s longevity program offers NAD+ therapyin three distinct delivery formats, giving patients flexibility to choose themethod that fits their lifestyle and goals.
NAD+ is a coenzyme — a molecule that helpsenzymes do their jobs. It participates in two broad categories of biologicalprocesses that are critical for aging.
First, energy metabolism. NAD+ is essentialfor converting the food you eat into cellular energy (ATP) through themitochondrial electron transport chain. When NAD+ levels drop, mitochondrialfunction declines, and you feel it as fatigue, brain fog, and reduced physicalstamina.
Second, cellular maintenance and repair. NAD+activates a family of proteins called sirtuins (SIRT1-7), often called the“longevity genes.” Sirtuins regulate DNA repair, inflammation, mitochondrialbiogenesis, and cellular stress responses. They’re essentially your cells’maintenance crew — and they can’t work without NAD+ as fuel.
NAD+ is also consumed by PARP enzymes duringDNA repair. As DNA damage accumulates with age, more NAD+ is diverted to repair,leaving less available for energy production and sirtuin activation. Thiscreates a vicious cycle: aging causes NAD+ depletion, and NAD+ depletionaccelerates aging.
Walk into any supplement store and you’ll findNAD+ precursors like NMN (nicotinamide mononucleotide) and NR (nicotinamideriboside) marketed as longevity supplements. While these precursors canmodestly raise NAD+ levels, they face significant limitations.
Bioavailability is a major issue. Oral NAD+precursors must survive the digestive system, be absorbed, and then beconverted through multiple enzymatic steps into active NAD+. Each step involvesloss. The actual amount of NAD+ that reaches your cells is a fraction of what’son the label.
Quality control is another concern. Thesupplement industry is loosely regulated compared to prescription medications.Testing has repeatedly found that many NAD+ supplements contain less activeingredient than claimed, or contain contaminants.
This is why Luvo offers clinical-grade NAD+therapy in formulations designed for superior delivery — not the sameover-the-counter products you can buy at a health food store. Our NAD+ optionsinclude pharmaceutical-grade injection, oral liquid drops, and nasal spray,each with distinct absorption characteristics.
Luvo’s longevity program offers three ways toreceive NAD+ therapy, each with specific advantages.
NAD+ injection delivers NAD+ directly into thebloodstream or subcutaneous tissue, bypassing the digestive system entirely.This provides the highest bioavailability of any delivery method. Injectionsare ideal for patients who want maximum cellular impact and are comfortablewith self-injection. Many patients report feeling noticeable improvements inenergy and mental clarity within days of starting.
NAD+ oral liquid drops offer a convenient,needle-free option. The liquid formulation is designed for sublingualabsorption — held under the tongue where it can enter the bloodstream throughthe mucous membranes, partially bypassing digestive degradation. This methodsuits patients who want daily dosing simplicity.
NAD+ nasal spray delivers NAD+ through thenasal mucosa, which provides rapid absorption and potential advantages forbrain-related benefits due to the proximity of the nasal passages to thecentral nervous system. Some research suggests intranasal delivery may supportcognitive function more directly than other routes.
Your Luvo provider can recommend the deliverymethod — or combination of methods — best suited to your goals, whether that’smaximum systemic NAD+ restoration, cognitive focus, or lifestyle convenience.
NAD+ therapy affects people differentlydepending on their baseline levels, age, and overall health. However, patientscommonly report improved energy levels and reduced fatigue, sharper mentalclarity and reduced brain fog, better sleep quality, faster recovery fromexercise, improved mood and reduced feelings of sluggishness, and a generalsense of vitality and well-being.
These benefits typically emerge within thefirst few weeks of consistent therapy and continue to develop over months. NAD+therapy is most effective as part of an ongoing protocol rather than a one-timetreatment — which is why Luvo’s longevity program is designed for sustaineduse.

The longevity conversation has exploded inrecent years. Podcasts, bestselling books, and a growing community ofresearchers and biohackers have brought the science of aging into mainstreamawareness. But beneath the hype, there’s a serious and rapidly evolving medicaldiscipline focused on one central question: how do we extend not just lifespan,but healthspan — the number of years you live in good health, free from chronicdisease and functional decline?
That’s the foundation of Luvo’s longevityprogram. It’s not about miracle cures or reversing the clock. It’s about usingevidence-based therapies to support your body’s own repair and regenerationsystems as they naturally slow down with age.
The wellness industry is flooded with productspromising to “reverse aging.” Most of these claims are unsupported by clinicalevidence. Longevity medicine is fundamentally different. It’s a clinical disciplinerooted in the biology of aging — specifically, the molecular and cellularmechanisms that drive age-related decline.
Researchers have identified several hallmarksof aging: mitochondrial dysfunction, cellular senescence, epigenetic changes,loss of proteostasis, and declining levels of critical molecules like NAD+ andgrowth hormone. Longevity medicine targets these mechanisms directly, usingtherapies that have measurable biological effects — not just cosmetic ones.
Competitors in the telehealth space —companies like Hims and Pomegranate — tend to focus on single-symptomtreatments. Luvo’s longevity program takes a systems-level approach, combiningmultiple therapies that address different hallmarks of aging simultaneously.
Luvo’s longevity program is built around fivemedications, each targeting a different aspect of age-related decline.
Sermorelin is a growth hormone-releasingpeptide that stimulates your pituitary gland to produce more of its own growthhormone. Growth hormone levels decline significantly with age, contributing tomuscle loss, increased body fat, reduced bone density, and slower recovery.Sermorelin restores this signaling naturally.
NAD+ therapy is available in three deliveryformats — injection, oral liquid drops, and nasal spray. NAD+ (nicotinamideadenine dinucleotide) is a coenzyme essential for cellular energy production,DNA repair, and activation of sirtuins — the proteins that regulate aging atthe cellular level. NAD+ levels decline by as much as 50% between ages 40 and60.
Vitamin B12/MIC is a lipotropic injectioncombining Vitamin B12 with methionine, inositol, and choline. This combinationsupports energy metabolism, fat metabolism, liver function, and methylation — abiochemical process critical for DNA maintenance and detoxification.
Together, these therapies create acomprehensive protocol addressing energy production, hormonal optimization,cellular repair, and metabolic health.
Luvo’s longevity program is designed foradults who are proactive about their health — people who don’t want to waituntil disease develops to take action. You might be a good candidate if you’reexperiencing age-related fatigue, brain fog, or declining physical performance,if you’re interested in optimizing your healthspan based on the latest science,if you want clinical-grade therapies under medical supervision rather thanover-the-counter supplements of questionable quality, or if you’re looking fora comprehensive approach rather than a single-product solution.
The program is available through Luvo’stelehealth platform, with licensed providers who specialize in longevitymedicine and can tailor a protocol to your specific needs and goals.
Many competitors offer individuallongevity-adjacent products — an NAD+ supplement here, a B12 shot there. Whatsets Luvo apart is the integrated program design. Our providers don’t justprescribe a single therapy; they assess your overall health profile and build aprotocol that combines therapies for synergistic benefit.
Sermorelin supports the hormonal axis. NAD+fuels cellular repair. B12/MIC optimizes metabolic pathways. Together, theywork on multiple fronts — and that’s the kind of comprehensive approach thatlongevity science actually supports.

There’s a graph that every longevityresearcher knows. It shows NAD+ levels in human tissue plotted against age. Theline goes in one direction: down. By age 50, most people have lost 40-50% ofthe NAD+ they had at 20. By 70, the decline can exceed 60%.
This isn’t just an interesting data point.NAD+ decline is now considered one of the fundamental drivers of aging — a rootcause, not merely a symptom. When NAD+ falls below critical thresholds, thecellular machinery that keeps you healthy starts to malfunction. Understandingthis decline — and taking action to address it — is one of the most impactfulthings you can do for your long-term health.
NAD+ decline isn’t caused by a single factor.It’s the result of multiple converging biological processes.
Increased CD38 activity is one of the primaryculprits. CD38 is an enzyme that consumes NAD+ as part of the immune response.As chronic, low-grade inflammation (sometimes called “inflammaging”) increaseswith age, CD38 activity rises, burning through NAD+ stores faster than they canbe replenished.
DNA damage accumulation also plays a majorrole. Every day, your cells sustain tens of thousands of DNA damage events fromnormal metabolic processes, environmental toxins, and UV radiation. The enzymePARP1, which repairs this damage, requires NAD+ as fuel. As damage accumulateswith age, PARP1 consumes more and more NAD+.
Decreased NAD+ biosynthesis compounds theproblem. The enzymes responsible for producing NAD+ from dietary precursors(like NAMPT) become less efficient with age, reducing the body’s ability toreplenish its stores.
The result is a supply-and-demand crisis:demand for NAD+ increases while supply decreases. This drives a cascade ofdownstream effects that manifest as the symptoms and diseases of aging.
When NAD+ levels fall, multiple criticalsystems are affected simultaneously.
Mitochondrial dysfunction is perhaps the mostimmediately noticeable. Mitochondria — your cells’ power plants — depend onNAD+ for energy production. Low NAD+ means less ATP, which you experience as fatigue,reduced stamina, and slower recovery. Over time, mitochondrial dysfunctioncontributes to virtually every age-related disease.
Impaired DNA repair leads to genomicinstability, accumulating mutations, and cellular senescence — the state wherecells stop dividing but don’t die, instead secreting inflammatory compoundsthat damage surrounding tissue.
Sirtuin deactivation occurs because thesirtuin family of proteins can’t function without NAD+. When sirtuins gooffline, the body loses critical regulation of inflammation, metabolism, stressresponse, and circadian rhythm. Research in animal models has shown thatrestoring sirtuin activity through NAD+ repletion can reverse many aspects ofaging.
Neurodegeneration is also linked to NAD+ decline.Brain cells are among the most metabolically active in the body and areparticularly vulnerable to NAD+ depletion. Declining NAD+ in the brain isassociated with cognitive decline, reduced neuroplasticity, and increased riskof neurodegenerative conditions.
The encouraging news is that NAD+ levels arenot fixed. Research has demonstrated that NAD+ repletion through directsupplementation or precursor administration can meaningfully raise NAD+ levelsin human tissues.
However, not all approaches are equallyeffective. Over-the-counter NAD+ precursors like NMN and NR can raise NAD+modestly, but their oral bioavailability is limited and the quality ofcommercial supplements varies widely.
Clinical-grade NAD+ therapy — the kind offeredthrough Luvo’s longevity program — provides several advantages. Luvo’s NAD+injection delivers the molecule directly, bypassing digestive losses formaximum impact. NAD+ oral liquid drops use sublingual delivery for improvedabsorption over standard capsules. NAD+ nasal spray offers rapid mucosalabsorption with potential cognitive advantages.
The choice of delivery method, dosing, andfrequency should be tailored to your individual needs — which is exactly whatLuvo’s clinical team provides.
The decline in NAD+ begins in your 30s andaccelerates through your 40s and 50s. Many longevity experts argue thatproactive NAD+ repletion should begin before symptoms of decline become obvious— in other words, before you feel old, not after.
That said, patients at any adult age canbenefit from NAD+ therapy. If you’re experiencing unexplained fatigue,cognitive fog, slow recovery, or a general sense that your body isn’tperforming the way it used to, declining NAD+ may be a contributing factor.
Luvo’s longevity program can help you assessyour needs and build a NAD+ protocol — whether standalone or as part of acomprehensive longevity approach including Sermorelin and Vitamin B12/MIC.Explore our NAD+ options: injection, oral liquid drops, and nasal spray.
The world of longevity peptides can feel likea maze. Sermorelin, Ipamorelin, CJC-1295, Tesamorelin, BPC-157 — the list ofpeptides marketed for anti-aging, recovery, and performance seems to growmonthly. For patients interested in growth hormone optimization, understandingthe differences between these peptides is essential for making safe, informedchoices.
Among the options, Sermorelin has emerged asthe gold standard for clinically supervised growth hormone optimization — andthere are compelling reasons why Luvo’s longevity program features it as a coretherapy.
Sermorelin is a GHRH (growth hormone-releasinghormone) analog with the longest clinical track record of any growth hormonepeptide. It was FDA-approved in 1997 for the treatment of growth hormonedeficiency, giving it decades of safety data that newer peptides simply don’thave.
The key distinction is how Sermorelin works.As a GHRH analog, it stimulates the pituitary gland to produce and releasegrowth hormone through the body’s own regulatory mechanisms. This means growthhormone release remains pulsatile (released in natural bursts rather thancontinuous elevation), the hypothalamic-pituitary axis retains feedbackcontrol, and the risk of supraphysiological growth hormone levels is minimized.
Other peptides work through differentmechanisms. Ipamorelin and GHRP-6 are growth hormone secretagogues thatstimulate growth hormone release through the ghrelin receptor pathway. CJC-1295is a long-acting GHRH analog that provides extended growth hormone stimulation.While these peptides can be effective, they have less long-term safety data andsome carry additional side effect profiles, including increased hunger (ghrelinpathway peptides) and cortisol or prolactin elevation.
For physicians prescribing growth hormoneoptimization as part of a longevity protocol, safety is the primaryconsideration. These are therapies intended for long-term use in otherwisehealthy adults — the risk-benefit calculation is different from treating anacute disease.
Sermorelin’s safety profile is well-established.Common side effects are mild and typically limited to injection-site reactionssuch as redness or swelling, transient headaches during the initial treatmentperiod, and flushing or dizziness that usually resolves with continued use.
Serious adverse events are rare in theclinical literature. Because Sermorelin works through the body’s naturalregulatory pathways, the risk of growth hormone excess — the primary concernwith direct HGH injection — is inherently limited. Your pituitary gland hasbuilt-in mechanisms to prevent overproduction, and Sermorelin respects thosemechanisms.
This safety profile is why Luvo’s medical teamchose Sermorelin over newer, less-studied peptide alternatives. In longevitymedicine, the goal is sustained benefit over years or decades — and thatrequires a therapy you can trust for the long haul.
Some clinics offer peptide “stacks” —combinations of multiple growth hormone peptides administered together forsynergistic effect. While there’s theoretical logic behind some combinations,the clinical evidence supporting specific stacks is limited, and combiningmultiple peptides increases the complexity and unpredictability of treatment.
Luvo’s approach is different. Rather thanstacking multiple growth hormone peptides, our longevity program combinesSermorelin with complementary therapies that work on entirely differentpathways: NAD+ for cellular energy and DNA repair, and Vitamin B12/MIC formetabolic optimization. This creates true synergy without the risks of peptidepolypharmacy.
The result is a protocol where each componenthas a clear, distinct role — and where the safety profile of each therapy iswell-understood individually.
If you’re interested in growth hormoneoptimization, Sermorelin through Luvo’s longevity program offers the mostclinically responsible path. Our providers will evaluate your health history,discuss your goals, and determine whether Sermorelin is appropriate for you.
Because Sermorelin’s effects develop gradually— optimal results typically emerge over 3-6 months of consistent use — it’s atherapy that rewards patience and commitment. The improvements in sleep,energy, body composition, and recovery are real, but they build over timerather than appearing overnight.
