It hijacks the very molecule your cells need to produce energy and repair DNA. Every drink forces your liver to burn through NAD+ (nicotinamide adenine dinucleotide) at rates far exceeding normal metabolism, leaving cells starved of the coenzyme required for mitochondrial function and cellular recovery. The hangover you feel the next morning isn&#39;t primarily dehydration. It&#39;s NAD+ bankruptcy at the cellular level.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Our team has worked with patients navigating metabolic health challenges for years. The relationship between alcohol consumption and NAD+ depletion is one of the most consistently overlooked mechanisms in both hangover recovery and long-term liver health.<\/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;\">How does alcohol deplete NAD+ in the body?<\/strong><\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Alcohol metabolism forces the liver to convert ethanol into acetaldehyde using the enzyme alcohol dehydrogenase (ADH), which consumes NAD+ as a cofactor. For every ethanol molecule processed, one NAD+ molecule is oxidized to NADH. Heavy drinking can deplete hepatic NAD+ levels by 30\u201350% within hours, impairing cellular energy production, DNA repair mechanisms, and sirtuin activation. The pathways responsible for longevity and metabolic regulation.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Most people assume hangovers stem from dehydration or acetaldehyde toxicity alone. The deeper truth: alcohol creates a metabolic crisis by draining the NAD+ pool faster than cells can regenerate it. This explains why symptoms. Fatigue, brain fog, nausea. Persist even after rehydration. This article covers the enzymatic pathway that links alcohol to NAD+ loss, how chronic drinking compounds the deficit over time, and what restoration strategies actually work based on current biochemical evidence.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">Why Alcohol Metabolism Drains NAD+ (The Enzymatic Cascade)<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">When ethanol enters the liver, it must be metabolized in two steps: first to acetaldehyde via alcohol dehydrogenase (ADH), then to acetate via aldehyde dehydrogenase (ALDH). Both reactions require NAD+ as an electron acceptor. For every gram of alcohol consumed. Roughly one standard drink contains 14 grams. Your liver oxidizes approximately 10\u201312 millimoles of NAD+ to NADH. A single night of heavy drinking (4\u20136 drinks) can shift the NAD+\/NADH ratio from the normal 700:1 to below 100:1 in hepatic tissue.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">This ratio matters because NAD+ is the oxidized form required for cellular respiration. When NADH accumulates, mitochondria can&#39;t run the electron transport chain efficiently, ATP production drops, and cells enter a state of metabolic stress. Sirtuins. The enzymes that regulate DNA repair, inflammation, and circadian rhythm. Require NAD+ to function. Chronic alcohol consumption suppresses SIRT1 activity by up to 40%, accelerating cellular aging and impairing the body&#39;s ability to respond to metabolic stress.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">The liver isn&#39;t the only tissue affected. Brain cells also experience NAD+ depletion during alcohol metabolism, though the mechanism differs slightly. Ethanol crosses the blood-brain barrier and is metabolized locally by catalase and cytochrome P450 enzymes, both of which generate oxidative stress that further depletes NAD+ pools. This explains the cognitive fog and impaired executive function that persist even after blood alcohol returns to zero.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">NAD+ Depletion and Chronic Alcohol Use (Long-Term Consequences)<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Acute depletion from a single drinking episode reverses within 24\u201348 hours in healthy individuals. Chronic use is different. Research published in Alcoholism: Clinical and Experimental Research found that individuals with alcohol use disorder (AUD) had baseline NAD+ levels 25\u201335% lower than controls even after weeks of abstinence. The body&#39;s NAD+ synthesis pathways. Primarily the salvage pathway using nicotinamide. Become impaired through repeated cycles of depletion and recovery.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Chronic NAD+ deficiency accelerates several pathological processes. Fatty liver disease (hepatic steatosis) develops when NAD+ levels drop too low to support beta-oxidation, the process by which fatty acids are broken down for energy. Without adequate NAD+, lipids accumulate in hepatocytes. Data from the NAFLD Foundation suggests that individuals who consume more than 14 drinks per week show a 3\u20134\u00d7 higher incidence of steatosis compared to non-drinkers, with NAD+ depletion identified as a primary metabolic driver.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">The relationship between nad+ and alcohol extends beyond the liver. Skeletal muscle, cardiac tissue, and neurons all rely on NAD+ for mitochondrial function. Chronic drinkers often present with reduced exercise capacity, cardiomyopathy risk, and accelerated cognitive decline. All linked to persistent NAD+ insufficiency. The NADH\/NAD+ imbalance also impairs gluconeogenesis, contributing to hypoglycemia during withdrawal.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">Can NAD+ Supplementation Mitigate Alcohol-Related Damage?<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">NAD+ precursors. Nicotinamide riboside (NR), nicotinamide mononucleotide (NMN), and niacin. Have gained attention as potential interventions. Animal studies show that NR supplementation (300\u2013500 mg\/kg) can restore hepatic NAD+ levels and reduce markers of liver inflammation in alcohol-fed rodents. Human data is more limited. A 2021 pilot study in The Journal of Clinical Endocrinology found that 1,000 mg daily NR increased whole blood NAD+ by 40% in chronic drinkers, though liver-specific NAD+ levels weren&#39;t measured directly.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Here&#39;s the honest answer: NAD+ precursors can&#39;t undo active alcohol toxicity. If you&#39;re currently drinking heavily, supplementation won&#39;t prevent the oxidative damage, acetaldehyde accumulation, or mitochondrial dysfunction that alcohol causes in real time. What precursors may support is recovery during abstinence. Helping the body rebuild depleted NAD+ pools faster than synthesis from dietary tryptophan alone. This matters most for individuals in early sobriety, where restoring metabolic function accelerates physical recovery.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">The evidence for preventive use. Taking NAD+ precursors before drinking to reduce hangover severity. Is weak. A small trial using 500 mg NR before alcohol consumption found no significant difference in subjective hangover scores or blood acetaldehyde levels compared to placebo. The rate-limiting factor isn&#39;t NAD+ availability during metabolism. It&#39;s the sheer volume of ethanol overwhelming detoxification pathways.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">NAD+ and Alcohol: Comparison of Recovery Interventions<\/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;\">Intervention<\/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;\">Mechanism<\/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;\">Evidence Quality<\/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 NAD+ Restoration<\/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;\">Abstinence (no supplementation)<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">Allows endogenous synthesis via salvage pathway (nicotinamide) and de novo pathway (tryptophan)<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">Strong.

NAD+ availability isn&#39;t the bottleneck during active alcohol metabolism. Enzymatic capacity is. Your liver can only process ethanol at roughly 7\u201310 grams per hour regardless of NAD+ levels. Pre-loading with NR or NMN doesn&#39;t increase ADH or ALDH activity, so acetaldehyde still accumulates at the same rate. One small trial using 500 mg NR before drinking found no reduction in hangover severity or acetaldehyde blood levels compared to placebo.<\/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&#39;m a Moderate Drinker \u2014 Does NAD+ Depletion Still Apply?<\/h3>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Yes, but the effect is dose-dependent and reversible. Consuming 1\u20132 drinks causes temporary NAD+ depletion (10\u201320% reduction in hepatic levels) that resolves within 12\u201324 hours in healthy individuals. The body&#39;s salvage pathway. Which recycles nicotinamide back into NAD+. Handles this load without long-term deficit. Problems arise with daily drinking or binge episodes (4+ drinks), where recovery time between exposures isn&#39;t sufficient for full restoration.<\/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 NAD+ Levels Don&#39;t Recover After I Quit Drinking?<\/h3>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Persistent NAD+ deficiency after 6\u20138 weeks of abstinence suggests either pre-existing metabolic dysfunction or severe hepatic damage. Cirrhosis and advanced fibrosis impair the liver&#39;s ability to synthesize NAD+ even without alcohol present. Baseline NAD+ testing (via whole blood assay) can confirm this. If levels remain 30% or more below reference range, consider co-supplementation with B-vitamins (B1, B2, B6). Cofactors required for NAD+ synthesis. Alongside NR or niacin under medical supervision.<\/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 NAD+ and Alcohol<\/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: you can&#39;t supplement your way out of drinking. NAD+ precursors, IV therapies, and &#39;hangover prevention&#39; stacks are marketed as metabolic insurance policies, but the biochemistry doesn&#39;t support that claim. Alcohol depletes NAD+ faster than any supplement can restore it during active consumption. The only intervention that prevents NAD+ bankruptcy is reducing or eliminating alcohol intake. Precursors can help during recovery. They&#39;re useful tools for rebuilding depleted pools after you stop. But they don&#39;t protect against oxidative damage, acetaldehyde toxicity, or mitochondrial dysfunction while you&#39;re still drinking. If NAD+ optimization matters to you, alcohol is the variable to address first.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">The relationship between nad+ and alcohol isn&#39;t just academic. It&#39;s the mechanism behind why chronic drinking ages you faster, impairs cognitive function, and prevents your body from recovering the way it did in your twenties. NAD+ is the currency your cells use to repair DNA, regulate inflammation, and produce energy. Alcohol forces them into deficit spending every single time you drink. The body can handle occasional deficits. It evolved for that. But chronic depletion is where irreversible damage accumulates. If you&#39;re navigating weight loss, metabolic health, or longevity optimization, understanding this trade-off matters more than any supplement protocol ever will.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">For patients working through metabolic recovery.

This depletion is the primary metabolic driver of hangovers and contributes to long-term liver damage.<\/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 NAD+ supplements prevent hangovers?<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\">No. Pre-loading with NAD+ precursors like nicotinamide riboside (NR) or NMN does not reduce hangover severity because NAD+ availability is not the rate-limiting factor during alcohol metabolism \u2014 enzymatic capacity is.

Niacin (vitamin B3) is equally effective and far less expensive but causes flushing in most users. Nicotinamide mononucleotide (NMN) shows promise in animal studies but lacks robust human trials in alcohol recovery contexts.

Baseline NAD+ levels decline with age \u2014 studies show a 50% reduction between ages 20 and 60 in multiple tissues. This means older adults start with less NAD+ reserve before drinking, and their salvage pathway (which recycles nicotinamide) operates less efficiently. Combined with reduced liver enzyme activity and slower alcohol clearance, age-related NAD+ decline contributes to prolonged hangover symptoms and slower recovery times.<\/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 are sirtuins and why do they matter for alcohol-related damage?<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\">Sirtuins are NAD+-dependent enzymes that regulate DNA repair, inflammation, mitochondrial function, and cellular stress responses. SIRT1, the most studied sirtuin, requires NAD+ to function. Chronic alcohol consumption suppresses SIRT1 activity by up to 40% through NAD+ depletion, impairing the body&#8217;s ability to repair oxidative damage and accelerating cellular aging. This mechanism links alcohol use to accelerated liver disease, cognitive decline, and metabolic dysfunction.<\/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 IV NAD+ therapy effective for alcohol detox or hangover recovery?<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\">No controlled trials support IV NAD+ therapy for alcohol recovery. While direct infusion raises plasma NAD+ levels temporarily, there is no evidence that NAD+ administered intravenously reaches liver cells or other tissues at therapeutic concentrations. Most NAD+ is rapidly degraded in the bloodstream before cellular uptake. The practice is expensive, unregulated, and lacks peer-reviewed evidence \u2014 oral NAD+ precursors like NR or niacin are far better supported.<\/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 moderate drinking still cause long-term NAD+ problems?<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\">Daily moderate drinking (1\u20132 drinks per day) can cause cumulative NAD+ stress if recovery time between exposures is insufficient. The salvage pathway that regenerates NAD+ from nicotinamide requires 12\u201318 hours to fully restore hepatic levels after moderate consumption. Daily drinking prevents complete restoration, leading to gradual baseline NAD+ decline over months to years. Occasional drinking (2\u20133 times per week) allows full recovery between episodes and does not typically cause chronic depletion.<\/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 dietary strategies support NAD+ restoration after alcohol use?<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\">NAD+ synthesis requires niacin (vitamin B3), which is found in poultry, fish, beef, mushrooms, and fortified grains. The salvage pathway also depends on B-vitamins (B1, B2, B6) as cofactors. A diet rich in tryptophan \u2014 eggs, turkey, cheese, nuts \u2014 supports de novo NAD+ synthesis, though this pathway is slower than salvage. Supplementing with 500 mg nicotinamide or 300 mg NR during early abstinence accelerates restoration beyond what diet alone achieves.<\/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>Alcohol depletes NAD+ by hijacking the enzyme needed for cellular energy and DNA repair \u2014 understanding this mechanism explains hangovers and long-term<\/p>\n","protected":false},"author":6,"featured_media":77732,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"_yoast_wpseo_title":"","_yoast_wpseo_metadesc":"","_yoast_wpseo_focuskw":"","footnotes":"","_flyrank_wpseo_metadesc":""},"categories":[1],"tags":[],"class_list":["post-77733","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/posts\/77733","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/comments?post=77733"}],"version-history":[{"count":1,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/posts\/77733\/revisions"}],"predecessor-version":[{"id":77734,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/posts\/77733\/revisions\/77734"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/media\/77732"}],"wp:attachment":[{"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/media?parent=77733"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/categories?post=77733"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/tags?post=77733"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
