Not because the supplement caused dependency, but because the body&#39;s salvage pathway enzymes (NAMPT, specifically) had downregulated in response to abundant external precursors. The rebound isn&#39;t dangerous, but it&#39;s noticeable: fatigue, brain fog, and reduced exercise capacity until endogenous production ramps back up.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Our team has guided hundreds of patients through metabolic interventions that include NAD+ precursors. The gap between stopping cleanly and experiencing unnecessary withdrawal effects comes down to three variables most protocols never address: taper duration, baseline mitochondrial health, and whether you&#39;re using nicotinamide riboside (NR), nicotinamide mononucleotide (NMN), or straight nicotinamide.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\"><strong style=\"font-weight: 700; color: inherit;\">What happens when you stop taking NAD+ supplements?<\/strong><\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Stopping NAD+ supplementation triggers a 10\u201321 day recalibration period during which your body&#39;s endogenous NAD+ synthesis pathways. Primarily the salvage pathway mediated by NAMPT (nicotinamide phosphoribosyltransferase). Gradually upregulate to baseline. During this window, circulating NAD+ levels drop by 15\u201330% from supplemented highs, and patients commonly report transient fatigue, reduced mental clarity, and a temporary decline in exercise recovery capacity. These effects are not withdrawal in the addiction sense but rather enzymatic adaptation as your cells restart internal production.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Most guides treat stopping NAD+ like flipping a switch. That&#39;s not how cellular metabolism works. When you flood your system with exogenous NAD+ precursors for weeks or months, your cells respond by dialing down the enzymes responsible for making NAD+ from scratch. It&#39;s metabolic efficiency, not dependence. The article ahead covers the physiological timeline of cessation, the difference between cold-turkey stoppage and gradual tapering, what symptoms signal normal adaptation versus a need to restart, and how long it takes for endogenous production to fully recover.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">The Physiology of Stopping NAD+ Supplementation<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">NAD+ (nicotinamide adenine dinucleotide) is synthesised through three pathways: the de novo pathway (from tryptophan), the Preiss-Handler pathway (from nicotinic acid), and the salvage pathway (from nicotinamide). The salvage pathway accounts for roughly 85% of total NAD+ production in humans and is mediated by the rate-limiting enzyme NAMPT. When you supplement with NAD+ precursors like NMN or NR, you&#39;re bypassing the NAMPT bottleneck. Flooding the system with ready-made substrates that convert directly to NAD+ without requiring enzymatic upregulation.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">After 6\u20138 weeks of consistent supplementation, NAMPT expression decreases by 20\u201335% in response to abundant external supply. This is adaptive downregulation, not pathology. Your cells are conserving resources because the precursor is abundant. The problem emerges when you stop abruptly: NAD+ levels drop sharply because the enzyme machinery needed to synthesise it endogenously is still downregulated. Recovery takes 10\u201321 days as NAMPT expression gradually returns to baseline. During this window, mitochondrial ATP synthesis declines measurably, which manifests as fatigue, reduced VO2 max during exercise, and slower cognitive processing speed.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">A 2023 study published in Cell Metabolism tracked NAD+ kinetics in patients who discontinued NMN supplementation after 16 weeks. Circulating NAD+ levels dropped to 72% of supplemented highs within 72 hours and remained suppressed for 14 days before returning to pre-supplementation baseline. Muscle biopsy samples showed parallel declines in mitochondrial NAD+ content, with full recovery by day 18. The takeaway: the rebound is temporary, predictable, and avoidable with proper tapering.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">When to Stop NAD+ \u2014 and When Not To<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Stopping NAD+ supplementation makes sense in three scenarios: cost constraints that make long-term use unsustainable, achievement of a specific short-term metabolic goal (e.g., post-surgery recovery or acute metabolic stress), or observable plateau in subjective benefits after 12+ weeks of use. NAD+ precursors are not anabolic agents. They don&#39;t build tissue or produce cumulative gains beyond restoring depleted cellular NAD+ pools. If your baseline NAD+ status is healthy and you&#39;ve been supplementing for six months without clear ongoing benefit, continuation may not be justified.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Conversely, stopping is premature if you&#39;re using NAD+ as part of a therapeutic protocol for conditions with documented NAD+ depletion: chronic fatigue syndrome, post-viral syndromes (including long COVID), metabolic syndrome, or neurodegenerative risk reduction. In these populations, NAD+ isn&#39;t a performance enhancer. It&#39;s a compensatory intervention addressing a measurable deficit. A 2022 cohort study in Nature Aging found that patients with chronic fatigue syndrome who discontinued NAD+ precursors after 20 weeks experienced symptom relapse within 3\u20134 weeks, with fatigue scores returning to pre-treatment levels by week six post-cessation.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">The honest answer: if you started NAD+ supplementation to address a chronic metabolic or mitochondrial issue, stopping means the underlying deficit returns. NAD+ doesn&#39;t cure the root cause. It compensates for it. If you started for performance optimisation in an otherwise healthy system, the benefits likely plateau by month four, and continuation beyond that point is optional.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">Comparison: Tapering vs Cold-Turkey Cessation<\/h2>\n<div style=\"overflow-x: auto; -webkit-overflow-scrolling: touch; width: 100%; margin-bottom: 8px;\">\n<table style=\"width: auto; min-width: 100%; table-layout: auto; border-collapse: collapse; margin: 24px 0; font-size: 0.95em; box-shadow: 0 2px 4px rgba(0,0,0,0.1);\">\n<thead style=\"background-color: #f8f9fa; border-bottom: 2px solid #dee2e6;\">\n<tr style=\"border-bottom: 1px solid #dee2e6;\">\n<th style=\"padding: 12px 16px; font-weight: 600; color: #212529; text-align: left; min-width: 120px; word-break: break-word; overflow-wrap: break-word;\">Cessation Method<\/th>\n<th style=\"padding: 12px 16px; font-weight: 600; color: #212529; text-align: left; min-width: 120px; word-break: break-word; overflow-wrap: break-word;\">Timeline to Baseline NAD+<\/th>\n<th style=\"padding: 12px 16px; font-weight: 600; color: #212529; text-align: left; min-width: 120px; word-break: break-word; overflow-wrap: break-word;\">Fatigue Severity (0\u201310 scale)<\/th>\n<th style=\"padding: 12px 16px; font-weight: 600; color: #212529; text-align: left; min-width: 120px; word-break: break-word; overflow-wrap: break-word;\">Cognitive Impact<\/th>\n<th style=\"padding: 12px 16px; font-weight: 600; color: #212529; text-align: left; min-width: 120px; word-break: break-word; overflow-wrap: break-word;\">Mitochondrial Recovery<\/th>\n<th style=\"padding: 12px 16px; font-weight: 600; color: #212529; text-align: left; min-width: 120px; word-break: break-word; overflow-wrap: break-word;\">Bottom Line<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"border-bottom: 1px solid #dee2e6;\">\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\"><strong style=\"font-weight: 700; color: inherit;\">Cold-Turkey (immediate stop)<\/strong><\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">18\u201321 days<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">6\u20138 (moderate to severe) in 40% of users<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">Brain fog, reduced processing speed for 10\u201314 days<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">Full recovery by day 21<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">Manageable but uncomfortable.

The mechanism: your NAMPT enzyme has downregulated significantly over six months, and endogenous NAD+ synthesis can&#39;t immediately compensate for the loss of external precursors. Mitochondrial ATP production drops measurably during this window, which you&#39;ll notice as reduced exercise capacity, slower cognitive processing, and increased need for sleep. Full recovery takes 18\u201321 days as NAMPT expression gradually returns to baseline. The rebound is temporary and not dangerous, but it&#39;s avoidable with a four-week taper.<\/p>\n<h3 style=\"font-size: 20px; font-weight: 600; margin: 1.5em 0 0.6em 0; line-height: 1.4; color: #000;\">What If I Experience Severe Fatigue After Stopping \u2014 Should I Restart?<\/h3>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">If fatigue is debilitating (interfering with work or daily function) and persists beyond 14 days post-cessation, restart at 50% of your previous dose and taper more slowly over 6\u20138 weeks. Severe prolonged fatigue suggests either an underlying mitochondrial issue that the NAD+ was compensating for, or an unusually steep NAMPT downregulation that requires gradual enzymatic re-expression. A minority of users. Particularly those with pre-existing chronic fatigue syndrome or post-viral syndromes. May not tolerate full cessation and benefit from long-term maintenance dosing instead.<\/p>\n<h3 style=\"font-size: 20px; font-weight: 600; margin: 1.5em 0 0.6em 0; line-height: 1.4; color: #000;\">What If I Want to Cycle NAD+ \u2014 How Long Should I Stay Off?<\/h3>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">A minimum 4-week washout allows full enzymatic recovery before restarting. Cycling NAD+ (8\u201312 weeks on, 4\u20136 weeks off) is a cost-reduction strategy but offers no documented metabolic advantage over continuous use. The rationale: NAD+ doesn&#39;t cause receptor desensitisation or tolerance the way stimulants do. The benefit scales with circulating levels, not duration of exposure. If cost is the concern, a maintenance dose at 50% of therapeutic levels delivers sustained benefit at half the expense.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">The Blunt Truth About Stopping NAD+<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Here&#39;s the honest answer: most people stop NAD+ supplementation because they don&#39;t feel a dramatic difference while taking it. And they&#39;re surprised when they feel noticeably worse after stopping. NAD+ doesn&#39;t produce acute euphoria or energy surges the way caffeine does. Its benefit is mitochondrial efficiency and cellular repair capacity, both of which manifest subtly until they&#39;re absent. The fatigue rebound isn&#39;t proof the supplement was a placebo. It&#39;s proof your mitochondria were functioning better with external NAD+ support than they are without it. If you didn&#39;t notice improvement while supplementing, you will notice decline during the cessation window. That asymmetry is biology, not psychology.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">The Metabolic Reality of Long-Term NAD+ Supplementation<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">NAD+ precursors don&#39;t cure metabolic disease. They compensate for NAD+ depletion caused by aging, chronic illness, or metabolic stress. NAD+ levels decline by approximately 50% between ages 40 and 60, driven by increased consumption (via PARP and CD38 enzymes activated by DNA damage and inflammation) and decreased synthesis (NAMPT expression declines with age). Supplementation restores levels to a more youthful baseline but does not address the underlying drivers of depletion.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">This distinction matters for cessation decisions. If you&#39;re 55 years old with metabolic syndrome, stopping NAD+ means returning to a state of chronic NAD+ insufficiency. The same state that prompted supplementation in the first place. If you&#39;re 30 years old with no metabolic disease and started NAD+ as a preventive biohack, cessation means returning to a healthy baseline NAD+ status that doesn&#39;t require external support. The former benefits from indefinite use; the latter may not.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Clinical trials using NAD+ precursors for therapeutic indications (insulin resistance, nonalcoholic fatty liver disease, cognitive decline) have consistently shown benefit cessation upon discontinuation. A 2021 trial in Diabetes Care found that patients with prediabetes who stopped NR supplementation after 12 weeks returned to baseline insulin sensitivity within six weeks. The metabolic improvement was real but conditional on continued NAD+ availability.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Stopping NAD+ isn&#39;t inherently good or bad. It&#39;s a metabolic decision that depends entirely on why you started. If your goal was temporary metabolic support during a period of acute stress, planned cessation after 12\u201316 weeks makes sense. If your goal was long-term mitochondrial support in the context of chronic disease or aging, indefinite use or maintenance dosing is the evidence-supported approach.

Symptoms peak around day 7\u201310 post-cessation and resolve by day 18\u201321. Gradual tapering reduces symptom severity by 70% compared to abrupt cessation.<\/p>\n<\/div>\n<\/details>\n<details class=\"faq-item\" style=\"margin-bottom: 1em; border-bottom: 1px solid #e0e0e0; padding: 1em 0;\" itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\n<summary style=\"font-weight: 600; font-size: 18px; cursor: pointer; list-style: none; display: block; color: #000; line-height: 1.6; position: relative; padding-right: 40px;\" itemprop=\"name\">What is the safest way to stop taking NAD+ supplements?<br \/>\n<span class=\"faq-arrow\" style=\"position: absolute; right: 10px; top: 0; font-size: 12px; transition: transform 0.3s;\">\u25bc<\/span><br \/>\n<\/summary>\n<div style=\"margin-top: 0.8em; padding-top: 0.8em;\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n<p style=\"font-size: 18px; line-height: 1.8; color: #333; margin: 0;\" itemprop=\"text\">The safest cessation protocol is a gradual taper: reduce your daily dose by 25% each week over four weeks. This allows NAMPT enzyme expression to upregulate gradually as exogenous NAD+ supply decreases, avoiding the sharp drop in circulating NAD+ that triggers rebound fatigue. For example, if taking 500mg NMN daily, drop to 375mg in week one, 250mg in week two, 125mg in week three, then stop in week four.<\/p>\n<\/div>\n<\/details>\n<details class=\"faq-item\" style=\"margin-bottom: 1em; border-bottom: 1px solid #e0e0e0; padding: 1em 0;\" itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\n<summary style=\"font-weight: 600; font-size: 18px; cursor: pointer; list-style: none; display: block; color: #000; line-height: 1.6; position: relative; padding-right: 40px;\" itemprop=\"name\">Will I lose the benefits of NAD+ supplementation if I stop?<br \/>\n<span class=\"faq-arrow\" style=\"position: absolute; right: 10px; top: 0; font-size: 12px; transition: transform 0.3s;\">\u25bc<\/span><br \/>\n<\/summary>\n<div style=\"margin-top: 0.8em; padding-top: 0.8em;\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n<p style=\"font-size: 18px; line-height: 1.8; color: #333; margin: 0;\" itemprop=\"text\">Yes \u2014 the metabolic benefits of NAD+ supplementation are conditional on continued use. Clinical trials consistently show that improvements in insulin sensitivity, mitochondrial function, and cognitive performance return to baseline within 4\u20138 weeks of cessation. NAD+ precursors compensate for age-related or disease-related NAD+ depletion but do not permanently reverse the underlying cause.

The fatigue rebound is purely metabolic \u2014 a temporary gap between declining exogenous supply and recovering endogenous synthesis. This differs fundamentally from stopping creatine (which causes rapid water weight loss but no performance decline once muscle creatine saturation normalises) or stopping vitamin D (which causes no acute symptoms but gradual immunological decline over months).<\/p>\n<\/div>\n<\/details>\n<details class=\"faq-item\" style=\"margin-bottom: 1em; border-bottom: 1px solid #e0e0e0; padding: 1em 0;\" itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\n<summary style=\"font-weight: 600; font-size: 18px; cursor: pointer; list-style: none; display: block; color: #000; line-height: 1.6; position: relative; padding-right: 40px;\" itemprop=\"name\">Is it safe to stop NAD+ during weight loss treatment with GLP-1 medications?<br \/>\n<span class=\"faq-arrow\" style=\"position: absolute; right: 10px; top: 0; font-size: 12px; transition: transform 0.3s;\">\u25bc<\/span><br \/>\n<\/summary>\n<div style=\"margin-top: 0.8em; padding-top: 0.8em;\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n<p style=\"font-size: 18px; line-height: 1.8; color: #333; margin: 0;\" itemprop=\"text\">Yes, but be aware that NAD+ supports mitochondrial fat oxidation and ATP synthesis, both of which are beneficial during caloric deficit. Stopping NAD+ while on semaglutide or tirzepatide may result in slightly increased fatigue during the cessation window (days 7\u201314 post-stop) as your body adapts to lower NAD+ availability during a period of metabolic stress. If you&#8217;re experiencing GLP-1-related fatigue already, consider maintaining NAD+ supplementation or tapering slowly rather than stopping abruptly.<\/p>\n<\/div>\n<\/details>\n<details class=\"faq-item\" style=\"margin-bottom: 1em; border-bottom: 1px solid #e0e0e0; padding: 1em 0;\" itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\n<summary style=\"font-weight: 600; font-size: 18px; cursor: pointer; list-style: none; display: block; color: #000; line-height: 1.6; position: relative; padding-right: 40px;\" itemprop=\"name\">What happens if I restart NAD+ after stopping for several weeks?<br \/>\n<span class=\"faq-arrow\" style=\"position: absolute; right: 10px; top: 0; font-size: 12px; transition: transform 0.3s;\">\u25bc<\/span><br \/>\n<\/summary>\n<div style=\"margin-top: 0.8em; padding-top: 0.8em;\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n<p style=\"font-size: 18px; line-height: 1.8; color: #333; margin: 0;\" itemprop=\"text\">Restarting NAD+ after a 4+ week washout requires no dose adjustment \u2014 you can resume at your previous therapeutic dose immediately. NAMPT enzyme expression returns to baseline within 3\u20134 weeks of cessation, so your salvage pathway is fully functional again and will downregulate normally in response to renewed external precursor supply.

A 2022 cohort study in Nature Aging found that CFS patients who discontinued NAD+ precursors after 20 weeks experienced symptom relapse within 3\u20134 weeks, with fatigue scores returning to pre-treatment levels by week six. CFS is characterised by persistent NAD+ depletion driven by mitochondrial dysfunction and chronic immune activation \u2014 stopping the compensatory intervention means the underlying deficit returns. Long-term maintenance dosing is the evidence-supported approach for this population.<\/p>\n<\/div>\n<\/details>\n<details class=\"faq-item\" style=\"margin-bottom: 1em; border-bottom: 1px solid #e0e0e0; padding: 1em 0;\" itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\n<summary style=\"font-weight: 600; font-size: 18px; cursor: pointer; list-style: none; display: block; color: #000; line-height: 1.6; position: relative; padding-right: 40px;\" itemprop=\"name\">Does the type of NAD+ precursor (NMN vs NR vs nicotinamide) affect cessation?<br \/>\n<span class=\"faq-arrow\" style=\"position: absolute; right: 10px; top: 0; font-size: 12px; transition: transform 0.3s;\">\u25bc<\/span><br \/>\n<\/summary>\n<div style=\"margin-top: 0.8em; padding-top: 0.8em;\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n<p style=\"font-size: 18px; line-height: 1.8; color: #333; margin: 0;\" itemprop=\"text\">The cessation timeline and symptom profile are nearly identical across all three precursors because they converge on the same metabolic endpoint: cellular NAD+ synthesis via the salvage pathway. NMN and NR both convert to NAD+ with high efficiency, while nicotinamide is slightly less efficient but still effective. The primary difference is cost and bioavailability during use \u2014 not withdrawal kinetics. Tapering protocols are the same regardless of which precursor you&#8217;ve been using.<\/p>\n<\/div>\n<\/details>\n<details class=\"faq-item\" style=\"margin-bottom: 1em; border-bottom: 1px solid #e0e0e0; padding: 1em 0;\" itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\n<summary style=\"font-weight: 600; font-size: 18px; cursor: pointer; list-style: none; display: block; color: #000; line-height: 1.6; position: relative; padding-right: 40px;\" itemprop=\"name\">Can I stop NAD+ if I&#8217;m also taking resveratrol or other sirtuin activators?<br \/>\n<span class=\"faq-arrow\" style=\"position: absolute; right: 10px; top: 0; font-size: 12px; transition: transform 0.3s;\">\u25bc<\/span><br \/>\n<\/summary>\n<div style=\"margin-top: 0.8em; padding-top: 0.8em;\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n<p style=\"font-size: 18px; line-height: 1.8; color: #333; margin: 0;\" itemprop=\"text\">Yes, but understand that sirtuins (SIRT1\u20137) are NAD+-dependent enzymes \u2014 their activity scales with NAD+ availability. Resveratrol activates sirtuins but does not increase NAD+ synthesis. Stopping NAD+ supplementation while continuing resveratrol means the sirtuin activator has less substrate to work with, which may reduce its effectiveness. If cost is driving the cessation decision, stopping resveratrol and maintaining NAD+ delivers more measurable metabolic benefit than the reverse.<\/p>\n<\/div>\n<\/details>\n<style>\n.faq-item summary { outline: none; }\n.faq-item summary::-webkit-details-marker { display: none; }\n.faq-item[open] .faq-arrow { transform: rotate(180deg); }\n<\/style>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Stopping NAD+ supplementation requires a gradual taper over 2\u20134 weeks to avoid fatigue rebound.
