Contents Home IV Therapy: Benefits, Safety, and What to Expect Reviewer | 27th April | Read time – 10 mins Every drug you swallow, every capsule, every supplement — before any of it reaches your cells, it has to survive the gut. The stomach acid, the intestinal wall, the liver’s first-pass metabolism: each stage filters, degrades, or transforms what you took. By the time a water-soluble vitamin reaches your bloodstream from an oral dose, you might be absorbing a fraction of what the label promised — less if you have gut inflammation, digestive issues, or are simply over 40, when absorption efficiency quietly begins to decline. IV therapy bypasses that entire pathway. A solution of nutrients, fluids, or therapeutic compounds goes directly into the vein — straight to circulation, delivered at 100% bioavailability, available to tissues within minutes. It’s the same principle hospitals have used for a century to deliver fluids to dehydrated patients, antibiotics to those too ill to swallow, and nutrition to people who cannot absorb food. Wellness IV therapy applies the same delivery mechanism to nutrients that have well-documented biological roles but limited oral absorption. This article covers what IV therapy is and how it works mechanically, why the delivery route matters pharmacologically, what types of IV therapy exist and what each targets, what to expect in a session, what the real risks are and how to assess whether a clinic is managing them properly, what it costs in India, and the specific case for IV therapy in Hyderabad. Contents What Is IV Therapy and How Does It Work? IV therapy — intravenous therapy — is the administration of a liquid solution directly into a vein through a small catheter, usually placed in the forearm. The solution bypasses the digestive system entirely and enters systemic circulation immediately. From there, it distributes to organs and tissues within minutes, governed by the same pharmacokinetic principles as any intravenous drug. The core concept is bioavailability — the proportion of a substance that reaches the bloodstream in an active form. Oral bioavailability varies enormously by substance, formulation, gut health, and individual metabolism. Intravenous bioavailability, by definition, is 100%. There is no absorption barrier, no first-pass hepatic metabolism, no gut-transporter saturation point. What goes in the bag reaches the blood. [1] Pharmacokinetic and mechanistic studies support plausible physiological benefits across antioxidant, immune, and metabolic pathways that oral delivery cannot reliably replicate. [5] The mechanism is simple to describe but requires careful execution. A cannula — a short, flexible plastic tube on a needle — is inserted into a peripheral vein. The needle is removed; the cannula stays. A drip line connects the cannula to a bag of solution, which flows by gravity or a controlled pump at a rate calibrated to the contents and the patient. Too fast, and some nutrients produce systemic reactions — flushing, nausea, a sensation of heat — because the body’s metabolic processing can’t keep up. At the correct rate, these effects don’t occur. What Types of IV Therapy Are Available? IV therapy is not a single treatment — it is a delivery mechanism applied to different therapeutic goals. The major categories used in wellness and integrative medicine settings are distinct in their ingredients, their evidence base, and who they’re best suited for. Vitamin C IV Therapy The most extensively researched IV nutrient therapy. At wellness doses (7.5–25g), vitamin C IV supports immune function, collagen synthesis, and adrenal recovery. At pharmacological doses (25–100g), it is used as integrative support in cancer care, exploiting the pro-oxidant mechanism that high-concentration ascorbate triggers in tumour microenvironments. The pharmacokinetic case for IV over oral is among the clearest of any nutrient. View A Sample > Glutathione IV Therapy Glutathione is the body’s master antioxidant — a tripeptide produced in the liver that neutralises reactive oxygen species, recycles other antioxidants, and supports phase II liver detoxification. It is almost entirely destroyed in the gut when taken orally, making IV delivery the only practical route to meaningfully raise systemic glutathione levels. Commonly used for skin brightening, liver support, and antioxidant loading.

Levels fall roughly 50% between age 25 and 50, impairing cellular energy, circadian rhythm, and the body’s capacity to repair DNA damage. [9] A randomised pilot study found IV NAD+ raises plasma and tissue levels faster and more completely than oral precursors like NMN or NR [7], making it the preferred route for people with significant depletion — chronic fatigue, brain fog, addiction recovery, or documented biological ageing. Sessions run 2–4 hours due to the slower required infusion rate. View A Sample > Myers’ Cocktail IV The original multi-nutrient IV protocol, developed by Dr. John Myers in the 1960s. A combination of magnesium, calcium, B vitamins (B1, B2, B5, B6, B12), and vitamin C in sterile saline. The most broadly applicable IV protocol — effective for fatigue, migraines, stress recovery, immune support, and athletic performance. Adequate B vitamin and mineral intake supports energy metabolism, cognitive function, and resilience under physical and psychological stress. [10] The fastest session in most menus (20–45 minutes) and the natural entry point for people new to IV therapy. View A Sample > Hydration IV Therapy Saline or lactated Ringer’s solution, sometimes with electrolytes, used to correct dehydration that oral fluid intake cannot rapidly address — post-illness, post-exercise, post-travel, or following significant alcohol consumption. The most clinically straightforward IV application, with the least controversy around efficacy. View A Sample > B12 IV Therapy Targeted at people with B12 deficiency or absorption issues — vegans and vegetarians, people over 50, those with pernicious anaemia or gut conditions that impair intrinsic factor. B12 supports neurological function, red blood cell formation, and energy metabolism. Oral B12 at high doses can compensate through passive absorption, but IV delivery is faster and more reliable for significant deficiency.

Contents Home Myers’ Cocktail IV Therapy: Benefits, Safety, and What to Expect Reviewer | 22nd April | Read time – 11 mins Dr. John Myers was a Baltimore physician who, in the 1960s, began treating patients with a simple idea: if the gut cannot reliably deliver the nutrients the body needs, bypass it. His formula — a blend of magnesium, calcium, B vitamins, and vitamin C delivered directly into the bloodstream — became one of the most widely administered IV nutrient protocols in the world. It was never patented, never proprietary. Just a formula that worked, passed from clinic to clinic across six decades. The reason it survived is that each ingredient addresses a specific and common deficit. Magnesium is chronically low in a large proportion of the population — processed food, stress, and soil depletion have seen to that. B vitamins are consumed rapidly by energy metabolism, and oral absorption is unreliable for significant portions of people over 40. Vitamin C is depleted faster than most people replenish it. Calcium supports neuromuscular function. Together, in a single IV infusion, they reset multiple systems simultaneously rather than addressing each one separately over weeks. This article covers what Myers’ Cocktail IV therapy does and what the evidence actually says for each component, how the formula works in the body, who it helps most, who should not receive it, what a session involves, what it costs in India, and what to look for in a provider. Contents What Does Myers’ Cocktail IV Therapy Actually Do? The Myers’ Cocktail works because each of its components has a distinct and well-documented biological role — and because IV delivery achieves the concentrations that drive those roles effectively. Here’s what the science says about each, and how honest to be about it. Does Myers’ Cocktail help with fatigue and energy? This is the most consistent clinical observation and the one with the most plausible mechanistic support. B vitamins — B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), and B12 — are cofactors in the Krebs cycle and electron transport chain, the two processes your mitochondria use to convert food into ATP. Without adequate B vitamin activity, energy production slows at the cellular level regardless of how much you eat or sleep. [1] A 2023 randomised double-blind trial in the International Journal of Medical Sciences found that B vitamin complex supplementation significantly reduced physical and mental fatigue scores and improved exercise performance in healthy adults. [2] IV delivery reaches therapeutic concentrations faster and more completely than oral supplementation, particularly for B12 in people with absorption issues. The energy mechanism is well-established; large IV-specific RCTs on fatigue in healthy adults are limited. The clinical outcome data is directionally consistent. Does Myers’ Cocktail reduce the frequency of migraines? Magnesium is the component most directly linked to migraine, and the evidence here is among the strongest for any single ingredient in the formula. Migraine sufferers consistently show lower serum and brain magnesium levels than non-sufferers. Magnesium stabilises neuronal membranes, reduces cortical spreading depression, and modulates serotonin receptor activity — all mechanisms relevant to migraine pathophysiology. [3] A meta-analysis published in PubMed found that intravenous magnesium reduces acute migraine attacks within 15 to 45 minutes of infusion, and oral magnesium supplementation reduces frequency and intensity over time. [4] A systematic review of randomised controlled trials concluded that high-dose magnesium provides Grade C evidence for migraine prophylaxis — modest but real. [5] For patients with frequent migraines who have suboptimal magnesium status, the Myers’ Cocktail makes particular sense. The evidence for magnesium specifically is moderate to strong. Does Myers’ Cocktail support immune function? Vitamin C is the immune-relevant component here, and its role is well-documented. Neutrophils concentrate vitamin C to levels up to 100 times higher than plasma to fuel chemotaxis, phagocytosis, and microbial killing. [6] A 2017 systematic review in Nutrients established that vitamin C supports both the innate and adaptive immune systems — including epithelial barrier function, lymphocyte proliferation, and the oxidative burst that destroys pathogens. [7] The Myers’ Cocktail delivers vitamin C at doses that meaningfully raise plasma levels. The immune support evidence is strong. Whether the combination with B vitamins and magnesium adds synergistic benefit is plausible but not directly studied. Does Myers’ Cocktail help with stress and burnout recovery? Magnesium is the key stress-response ingredient. It acts as a natural antagonist at NMDA receptors — the same receptors that become hyperactive under chronic psychological stress — and helps regulate the HPA axis that controls cortisol production. Chronically elevated stress depletes magnesium, and magnesium depletion amplifies the stress response in a reinforcing cycle that oral supplementation alone often fails to break quickly enough. [8] B5 (pantothenic acid) is required for adrenal cortex function and cortisol synthesis. B6 is involved in serotonin and dopamine production — the neurotransmitters most directly affected by burnout. Vitamin C, as discussed in the adrenal therapy context, is consumed rapidly by the adrenals during stress. The Myers’ Cocktail addresses all three pathways simultaneously. The mechanistic basis is sound; direct RCT evidence on burnout recovery specifically is limited. Does Myers’ Cocktail improve athletic performance and recovery? Magnesium supports muscle contraction, oxygen delivery, and protein synthesis — all relevant to athletic performance. Vitamin C reduces exercise-induced oxidative damage and mitigates the post-exertion immune suppression window. B vitamins support the energy metabolism that exercise demands. For athletes with high training loads, frequent illness, or sluggish recovery, the combination addresses the physiological depletion pattern that follows sustained exertion. The individual ingredient evidence is moderate to strong; Myers’ Cocktail-specific sports performance RCTs are limited. Reviewer | Date | Read time How Does Myers’ Cocktail Work in Your Body? The formula Dr. Myers developed — and Alan Gaby later popularised and documented in a 2002 review — typically contains: magnesium chloride, calcium gluconate, thiamine (B1), riboflavin (B2), pyridoxine (B6), hydroxocobalamin (B12), dexpanthenol (B5), vitamin C, and sterile water. Different clinics adjust the ratios and sometimes add B-complex concentrates. The total volume is typically 100–250ml infused over

Contents Home Vitamin C IV Therapy: Benefits, Safety, and What to Expect Reviewer | 22nd April | Read time – 11 mins Your body cannot make vitamin C. Unlike almost every other mammal on the planet, humans lost the enzyme for synthesising ascorbic acid roughly 40 million years ago. We depend entirely on diet — and for most people living under chronic stress, eating inconsistently, or managing frequent illness, dietary intake is not keeping pace with what the body actually needs. The gap matters because vitamin C is not simply an antioxidant. It sits at the centre of collagen production, immune cell function, adrenal hormone synthesis, iron absorption, and the body’s ability to neutralise the oxidative load that modern life continuously generates. When levels fall — which they do faster under stress, illness, smoking, or poor sleep — every one of those systems weakens. This article covers what Vitamin C IV therapy does and where the evidence is strongest, how ascorbic acid works in your body, why IV delivery achieves plasma levels that no oral supplement can reach, who should not receive it, what a session involves, what it costs in India, and what to look for in a provider. Contents What Does Vitamin C IV Therapy Actually Do? There are five clinical areas where Vitamin C IV therapy shows meaningful evidence. Some have randomised controlled trials behind them. Some rest on strong mechanistic data with human evidence still catching up. Here’s what the science actually says. Does Vitamin C IV therapy support immune function? Yes! Neutrophils — your first line of immune defence — actively concentrate vitamin C to levels up to 100 times higher than plasma. [1] They use it to fuel chemotaxis, phagocytosis, and the oxidative burst that kills microbes. When vitamin C is depleted, all three processes slow. A 2017 systematic review in Nutrients documented how vitamin C supports epithelial barrier function, lymphocyte development, and neutrophil activity — a coordinated picture of immune dependence on ascorbate. [2] A subsequent 2019 systematic review of randomised controlled trials found that IV vitamin C specifically improved neutrophil chemotaxis in hospitalised patients. [3] For frequent illness, slow recovery from infection, or high-exposure periods, the immune rationale is well-supported. The evidence here is strong. Does Vitamin C IV therapy improve skin and stimulate collagen? It does, through one of the most thoroughly described mechanisms in skin biology. Vitamin C is an essential cofactor for prolyl hydroxylase and lysyl hydroxylase — the enzymes that stabilise and crosslink collagen fibres. Without adequate ascorbate, procollagen cannot mature. The result is skin that loses structure faster, heals more slowly, and responds less well to aesthetic treatments. A 2022 review in Antioxidants (PMC9495646) confirmed that vitamin C stimulates procollagen gene expression and promotes collagen maturation at both the transcription and post-translational stages. [4] Vitamin C also suppresses tyrosinase, reducing melanin production and helping even skin tone over time. The collagen mechanism is not in question; IV-specific RCT data on aesthetics is still building. Most patients notice improved radiance within 2 to 4 weeks of a course. Structural improvements in elasticity take 6 to 8 weeks to become perceptible. Does Vitamin C IV therapy speed up recovery from illness or exercise? It shortens recovery — not by preventing illness outright, but by accelerating the body’s resolution of it. During infection or intense physical stress, vitamin C is consumed rapidly by the immune response. A meta-analysis by Hemilä and Chalker found therapeutic vitamin C supplementation reduced cold duration by roughly 8% in adults and 14% in children. [5] A 2020 review in Frontiers in Immunology noted that vitamin C reduces exercise-induced cortisol and mitigates the post-exertion immune suppression window that leaves athletes vulnerable to illness. [6] The evidence is moderate and directionally consistent across populations. Does Vitamin C IV therapy support adrenal function and stress resilience? Adrenal glands contain the highest concentrations of vitamin C of any tissue in the body. They use it to synthesise noradrenaline and adrenaline — the catecholamines that drive your stress response. Under chronic or acute psychological stress, the adrenals consume vitamin C rapidly. Replenishing it supports catecholamine synthesis efficiency and helps blunt the cortisol overshoot that prolongs recovery from high-demand periods. The mechanistic evidence is strong; human RCT data on IV delivery for adrenal support specifically is still limited. Can high-dose Vitamin C IV therapy support cancer care? At the pharmacological concentrations achievable only through IV delivery, vitamin C acts as a pro-oxidant in tumour microenvironments — generating hydrogen peroxide selectively in cancer cells through a mechanism related to differences in catalase activity. [7] A pharmacokinetic study in Clinical Pharmacokinetics (PMC9439974) found that IV doses up to 100g elicited no adverse effects while reaching plasma concentrations unreachable by any oral route. [8] Phase I and II oncology trials have demonstrated safety and quality-of-life improvements alongside standard chemotherapy. These are not curative claims, and this is not a treatment to pursue outside oncology-supervised care. The mechanism is well-described; large RCT outcome data is actively being built. Reviewer | Date | Read time How Does Vitamin C Work in Your Body? Vitamin C — ascorbic acid, or ascorbate in its ionised form — is a water-soluble molecule that acts primarily as an electron donor. This single chemical property underlies its range of biological effects: it donates electrons to neutralise free radicals, activate enzyme cofactors, and maintain the redox state that keeps cellular machinery running correctly. In the gut, vitamin C is transported across the intestinal wall by sodium-dependent vitamin C transporters (SVCT1 and SVCT2). These transporters saturate at oral doses around 500–1000mg — which is why very high oral doses don’t proportionally raise plasma levels. The system is simply full. [9] Intravenous delivery bypasses this bottleneck entirely, allowing plasma concentrations that no oral dose can achieve. Once in circulation, vitamin C is taken up preferentially by metabolically active or stressed tissues. Adrenals, white blood cells, and skin fibroblasts concentrate it far above plasma levels. It recycles other antioxidants — vitamin E and glutathione

Contents Home Glutathione IV Therapy: Benefits, Safety, and What to Expect Reviewer | 6th March | Read time – 11 mins Your body already makes glutathione. Every cell, every day. It’s a small molecule built from three amino acids, and it quietly handles some of the most important work happening inside you right now — neutralising damage, clearing out toxins, keeping your immune system sharp, regulating the pigment in your skin. The problem is that your supply peaks in your twenties and drops from there. Stress, pollution, alcohol, bad sleep, illness — they all drain it faster. By the time most people start noticing dull skin, low energy, or sluggish recovery, their glutathione is already well below where it should be. That’s where Glutathione IV therapy comes in. And that’s what this article is about — what the treatment does, what the research actually shows, who it’s for, who it’s not for, and what you should know before booking a session. Contents What Does Glutathione IV Therapy Actually Do? There are five reasons people seek this treatment. Some have strong clinical evidence behind them. Some are still emerging. You deserve to know which is which, so we’ll be specific. Does glutathione brighten skin? Yes. This is the benefit that drives most of the search interest in India, and the science supports it — with some important caveats. Glutathione inhibits tyrosinase, the enzyme that drives melanin production, and shifts your pigment balance from darker eumelanin toward lighter pheomelanin. A 2025 narrative review in Cureus analysed multiple clinical studies and confirmed measurable reductions in melanin index scores, with IV delivery producing the most pronounced effects. [1] But the timeline is not what social media suggests. The first few sessions are invisible — the changes are cellular. Around session four to six, your skin texture improves and a subtle glow starts to show. By weeks six to eight, most patients see genuine brightening and more even tone. After that, you’re maintaining. Your body doesn’t stop making melanin, so periodic sessions are what keep you there. The evidence is moderate. The mechanism is well-understood. The results are real but gradual, and they require patience and consistency. Does it help your liver? This is where the science is strongest. Glutathione is central to Phase II liver detoxification — the process where your liver takes toxins, drug metabolites, and heavy metals and converts them into water-soluble compounds your body can eliminate. Most of the glutathione circulating in your blood originates from the liver. When it runs low there, the effects cascade. In India, IV glutathione holds CDSCO approval for alcoholic fatty liver, liver fibrosis, cirrhosis, and alcoholic hepatitis. [9] A 2025 review in Biomedicines covering a decade of research found consistent improvements in ALT levels and oxidative stress markers among patients treated with glutathione, with benefits persisting months after treatment ended. [8] If you live in an Indian city, drink moderately, or take medication regularly, your liver is processing more than you probably realise. The evidence here is strong. Does it boost immunity? Glutathione fuels both branches of your immune system — the innate first responders and the adaptive forces that learn and remember specific threats. It supports natural killer cell activity and T-lymphocyte proliferation, which are the mechanisms your body relies on to identify and eliminate pathogens. A 2018 clinical study in the European Journal of Clinical Nutrition showed that glutathione supplementation elevated both NK cell cytotoxicity and lymphocyte counts. [3] IV delivery’s higher absorption rate should amplify these effects, though direct IV-specific immune trials are still catching up. In a country where urban air quality, seasonal illness cycles, and post-pandemic awareness have made immune resilience a genuine priority, this benefit is worth paying attention to. The evidence is moderate and growing. What about anti-ageing? Biological ageing is driven, in significant part, by the accumulated oxidative damage to your DNA, mitochondria, and cell membranes over decades. Glutathione is the molecule your body uses to prevent and repair that damage. It scavenges free radicals directly, protects mitochondrial function, and recycles other antioxidants including vitamins C and E. [6] The biochemistry here is not contested. What’s still being studied is whether supplementing glutathione intravenously translates into measurable anti-ageing outcomes in controlled trials. The mechanism is strong. The clinical outcome data is still being built. Is there a neurological benefit? Glutathione is the most abundant antioxidant in the human brain. Depleted levels in the substantia nigra have been consistently documented in patients with Parkinson’s disease, and neuroprotective research is active. This is emerging science, not a reason to book a session today, but it’s worth knowing about as the field develops. Reviewer | Date | Read time How Does It Work in Your Body? Glutathione is a tripeptide — three amino acids (cysteine, glycine, glutamic acid) linked together. Your liver synthesises it, and it’s found in virtually every human cell at concentrations comparable to glucose and potassium. That tells you something about how fundamental it is. It operates on four fronts simultaneously. As an antioxidant, it neutralises free radicals before they can damage your cells, and it regenerates vitamins C and E in the process. As a detoxifier, it binds to toxins and heavy metals in the liver so your kidneys can excrete them. [7] As an immune modulator, it fuels the cells that detect and destroy threats. And as a pigment regulator, it inhibits the enzyme that produces melanin. The reason this matters for the IV conversation is that glutathione levels decline naturally with age, and that decline is accelerated by exactly the things most urban adults deal with daily — pollution, stress, poor sleep, processed food, and alcohol. The molecule your body depends on for protection is the same one it loses fastest under pressure. Why Glutathione IV Therapy Instead of Oral Supplements? Glutathione is a peptide, and your digestive system is built to dismantle peptides. That’s its function. When you swallow a glutathione capsule, stomach acid and intestinal enzymes degrade a significant portion of

Contents Home NAD+ IV Therapy: Benefits, Safety, and What to Expect Reviewer | 5th March, 2026 | Read time 11 mins NAD+ is a coenzyme your body makes and uses continuously. It sits inside every cell and powers energy production. Without it, your mitochondria cannot convert food into ATP — the fuel your body runs on. By age 40, most people have roughly half the NAD+ they had at 25. The drop matters because NAD+ doesn’t just run energy. It fuels the enzymes that repair DNA, regulate inflammation, and control your body’s internal clock. As levels fall, these systems slow down. The result is a familiar cluster — flatter energy, slower recovery, slightly reduced mental sharpness — that’s easy to blame on age rather than on a specific biochemical change. This article covers what NAD+ IV therapy does, how the molecule works, where the evidence is strong and where it’s still building, who should not get this treatment, what a session involves, what it costs, and what to look for in a provider. Contents What Does NAD+ IV Therapy Actually Do? There are five clinical areas where NAD+ IV therapy shows meaningful evidence. Some have randomised controlled trials behind them. Some rest on strong mechanistic data with human evidence still catching up. Here’s what the science actually says. Does NAD+ IV therapy restore energy? Yes. Your cells produce ATP through a process called oxidative phosphorylation. NAD+ carries electrons through the chain that powers this process. When NAD+ is depleted, the chain runs less efficiently. You make less ATP from the same food. The fatigue that results doesn’t fix with sleep — because the problem is energy production, not rest. A 2018 study in Nature Communications found NAD+ precursor supplementation raised cellular NAD+ in healthy middle-aged adults over 12 weeks. [5] IV delivery gets there faster and at higher concentrations. Most people with genuine depletion notice a difference within 24 to 72 hours of a session. The mechanistic evidence is strong; IV-specific RCT data on fatigue is still growing. Does NAD+ support cognitive function? It does. Neurons are the most energy-hungry cells in the body. They depend on NAD+ for ATP, mitochondrial function, and the DNA repair enzymes that handle constant neuronal activity. When NAD+ falls, neuronal energy drops and protective repair slows. [6] A 2022 phase I trial in Cell Metabolism found NAD+ precursor supplementation improved brain metabolism in Parkinson’s patients — supporting the idea that NAD+ availability matters for neuronal energy efficiency broadly. [7] Slower processing, reduced word recall, ideas connecting less fluidly — these are consistent with depleted NAD+. The evidence is moderate and directionally consistent. Does NAD+ IV therapy support addiction recovery? This is where the most direct clinical data exists. A 2022 pilot study of 50 patients found significant reductions in cravings, anxiety, and sleep disturbance after IV NAD+ treatment for substance use disorder. [9] The mechanism is NAD+’s role in dopamine regulation and reducing the cellular stress that drives withdrawal. The evidence here is moderate to strong. Does NAD+ IV therapy help with sleep? NAD+ regulates circadian rhythms through SIRT1, the sirtuin that helps set your internal clock. Low NAD+ weakens this signal. Deep sleep deteriorates. Poor sleep then impairs the overnight recycling that replenishes NAD+ — a reinforcing cycle. [4] For frequent travellers, shift workers, or anyone with chronic sleep debt, restoring NAD+ is part of the fix. The mechanistic evidence is strong; direct IV sleep trial data is limited. Can NAD+ slow biological ageing? The mechanism is solid. Sirtuins — enzymes that regulate inflammation, gene expression, and cellular stress — require NAD+ as fuel. They are central to how fast cells age. NAD+ activates them; depletion silences them. [3] Whether IV supplementation produces measurable longevity outcomes in humans hasn’t been answered by clinical trials yet. The mechanism is well-established. The long-term human outcome data is still being built. How Does NAD+ Work in Your Body? NAD+ (nicotinamide adenine dinucleotide) is a coenzyme — it makes enzymes work. It exists in two states: NAD+ (oxidised) and NADH (reduced). Shuttling between these states is how your mitochondria convert food into ATP. Without NAD+, that conversion stops. Three enzyme families compete for the same NAD+ pool. Sirtuins use it to regulate inflammation and gene expression. PARPs consume it to repair DNA damage — tens of thousands of repairs per cell per day. CD38 breaks it down during immune signalling. All three pull from the same shrinking supply. [2] The decline accelerates with age because production slows while consumption rises. NAMPT — the enzyme that drives NAD+ recycling — slows down. CD38 activity increases as inflammatory load builds. Diet and exercise help at the margins. Neither closes the gap at the enzyme level. [3] Why IV Instead of Oral Supplements? Oral NAD+ precursors — NMN and NR — are legitimate. They raise NAD+ over time and are well tolerated. For someone without acute symptoms who wants steady optimisation, they’re a sensible first step. The difference is speed and concentration. Oral precursors pass through the gut and liver before reaching circulation. Absorption rates run 15–40% depending on formulation. A 2024 randomised pilot study found IV NAD+ raised whole blood NAD+ substantially faster and higher than oral supplementation at the same dose. [8] IV bypasses digestion entirely — 100% enters the bloodstream directly, and peak levels arrive within the infusion window. For significant depletion, that speed matters. IV resets the baseline. Oral supplements maintain it. They work together, not against each other. NAD+ IV Therapy If you want to know whether NAD+ IV therapy fits what you’re experiencing, our clinical team is happy to walk you through it Book Now Learn More Is NAD+ IV Therapy Safe? Yes, with clinical oversight. The most common side effects — nausea, chest tightness, flushing, headache — are caused by infusion rate, not the molecule. Delivered too fast, NAD+ overwhelms the body’s metabolic processing. Delivered slowly over 2 to 4 hours, reactions are uncommon and mild. A pharmacokinetic study found no adverse
