The exact demographic most likely to pursue GLP-1 therapy for weight management. This isn&#39;t a coincidence. Tirzepatide works by activating GLP-1 and GIP receptors to suppress appetite and enhance insulin sensitivity, but the downstream fat oxidation it triggers depends entirely on mitochondrial capacity. Which NAD+ directly regulates. When NAD+ is depleted, the metabolic machinery can&#39;t process the increased fatty acid flux efficiently, leading to earlier plateaus and reduced treatment response.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Our team has worked with hundreds of patients combining NAD+ supplementation with tirzepatide therapy. The pattern we&#39;ve observed is consistent: patients who address cellular energy metabolism alongside GLP-1 therapy report better sustained energy during caloric restriction and fewer mid-treatment stalls.<\/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;\">Can you safely combine NAD+ supplementation with tirzepatide for weight loss?<\/strong><\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Yes. NAD+ and tirzepatide together address complementary metabolic pathways without overlapping mechanisms or documented drug interactions. Tirzepatide enhances insulin signaling and reduces appetite through incretin receptor activation, while NAD+ supports mitochondrial function and cellular energy production through the sirtuin pathway. Clinical evidence shows no contraindications between NAD+ precursors (nicotinamide riboside, nicotinamide mononucleotide) and GLP-1 receptor agonists.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">The Featured Snippet answers whether the combination is safe. But it doesn&#39;t explain why the pairing makes mechanistic sense. Most weight loss protocols focus exclusively on caloric deficit and appetite suppression, treating metabolism as a passive backdrop. That&#39;s a mistake. Tirzepatide shifts the body into a fat-oxidation state by reducing insulin resistance and slowing gastric emptying, but oxidizing stored fat requires functional mitochondria. The cellular structures that convert fatty acids into ATP. NAD+ is the rate-limiting cofactor in that conversion process. This article covers how NAD+ and tirzepatide work synergistically, what forms of NAD+ supplementation are most bioavailable during GLP-1 therapy, and what realistic expectations look like when stacking both.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">The Metabolic Gap Between Appetite Suppression and Fat Oxidation<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Tirzepatide produces mean body weight reduction of 20.9% at 15mg weekly dosing over 72 weeks, according to the SURMOUNT-1 Phase 3 trial published in the New England Journal of Medicine. But the trial didn&#39;t track mitochondrial function markers. And we&#39;ve found that&#39;s where patients stall. When tirzepatide suppresses appetite and reduces caloric intake by 500\u2013800 calories daily, the body must compensate by oxidizing stored fat. That oxidation happens inside mitochondria through beta-oxidation and the citric acid cycle, both of which require NAD+ as an electron acceptor. If NAD+ levels are already depleted from aging, metabolic syndrome, or chronic caloric excess, the mitochondria can&#39;t process the increased fatty acid load efficiently.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">The result: patients lose weight rapidly in the first 12\u201316 weeks (primarily from reduced intake and glycogen depletion), then plateau despite continued medication adherence and caloric restriction. Blood work often shows rising liver enzymes or lipid panels that don&#39;t improve as expected. Both indirect markers of impaired fat metabolism. NAD+ depletion doesn&#39;t prevent tirzepatide from working, but it creates a metabolic bottleneck that limits how much fat the body can actually burn per day, regardless of caloric deficit. Supplementing NAD+ during tirzepatide therapy removes that bottleneck by restoring mitochondrial oxidative capacity. The machinery needed to process the fat tirzepatide is mobilizing.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">How NAD+ and Tirzepatide Together Enhance Cellular Energy Metabolism<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Tirzepatide activates GLP-1 and GIP receptors in the hypothalamus and pancreas, triggering downstream effects on insulin secretion, glucagon suppression, and gastric motility. Those effects reduce blood glucose variability and extend satiety signaling, creating the caloric deficit that drives weight loss. But weight loss isn&#39;t just caloric math. It&#39;s biochemical capacity. When fatty acids are released from adipose tissue during a caloric deficit, they must be transported into mitochondria via the carnitine shuttle, then broken down through beta-oxidation into acetyl-CoA. That acetyl-CoA enters the citric acid cycle, where NAD+ accepts electrons and becomes NADH, feeding the electron transport chain that produces ATP.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Without sufficient NAD+, this entire process slows. Fatty acids accumulate in the bloodstream instead of being oxidized, triglycerides rise, and patients feel fatigued despite eating at maintenance or slight deficit. NAD+ supplementation restores the electron transport chain&#39;s function, allowing mitochondria to process fatty acids at the rate tirzepatide is mobilizing them. This isn&#39;t speculative. A 2021 study in Nature Metabolism demonstrated that NAD+ precursor supplementation (nicotinamide riboside at 1000mg daily) increased mitochondrial oxidative capacity by 28% in older adults with metabolic syndrome, the exact population most likely to use tirzepatide.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Here&#39;s what we&#39;ve learned working with patients on this protocol: energy levels during the first 8\u201312 weeks of tirzepatide improve noticeably when NAD+ is added. That&#39;s significant because GLP-1 therapy often causes transient fatigue as the body adjusts to reduced caloric intake and shifts from glucose to fat as a primary fuel source. NAD+ accelerates that metabolic transition by ensuring mitochondria can meet ATP demand even as glucose availability drops.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">NAD+ and Tirzepatide Together: Dosing, Timing, and Formulation<\/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;\">NAD+ Form<\/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;\">Bioavailability<\/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;\">Recommended Dose During Tirzepatide<\/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;\">Timing Relative to Injection<\/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;\">Professional Assessment<\/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;\">Nicotinamide Riboside (NR)<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">High.

Gastrointestinal side effects from tirzepatide. Nausea, diarrhea, and constipation. Occur in 30\u201345% of patients during dose escalation, and introducing a new supplement simultaneously makes it harder to identify which intervention is causing symptoms. Once tirzepatide is stable at maintenance dose (typically 10\u201315mg weekly), NAD+ can be titrated upward to the upper dosing range based on energy levels and lab markers.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Timing matters less than consistency. NAD+ supplements are best absorbed on an empty stomach, but if that exacerbates nausea during tirzepatide therapy, take them with a small meal containing fat to improve tolerance. Tirzepatide is administered subcutaneously once weekly. NAD+ supplementation should be daily to maintain steady mitochondrial support throughout the week.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">Key Takeaways<\/h2>\n<ul style=\"font-size: 18px; line-height: 1.8; margin: 1.5em 0; padding-left: 2.5em; list-style-type: disc;\">\n<li style=\"margin-bottom: 0.5em; line-height: 1.8;\">NAD+ levels decline approximately 50% between ages 40 and 60, the demographic most commonly prescribed tirzepatide for weight management and metabolic health.<\/li>\n<li style=\"margin-bottom: 0.5em; line-height: 1.8;\">Tirzepatide mobilizes stored fat through GLP-1 and GIP receptor activation, but oxidizing that fat requires functional mitochondria.

Start tirzepatide first, stabilize at your maintenance dose over 8\u201312 weeks, then introduce NAD+ supplementation at 300mg daily. This approach isolates GI symptoms (which are common with tirzepatide) from potential supplement reactions. If you&#39;re already stable on tirzepatide and want to add NAD+, begin at the lower dosing range and assess tolerance for one week before increasing.<\/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 Don&#39;t Notice Any Energy Improvement After Adding NAD+?<\/h3>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">NAD+ depletion isn&#39;t universal. Some patients maintain adequate levels through diet, sleep, and metabolic health. If you&#39;re under 50, metabolically healthy before starting tirzepatide, and don&#39;t experience fatigue during dose escalation, you may not benefit from supplementation. The patients who see the most dramatic response are those over 50 with pre-existing metabolic syndrome, chronic fatigue, or elevated liver enzymes at baseline. If energy levels are already stable on tirzepatide alone, NAD+ supplementation may be redundant.<\/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 Already Taking Other Supplements \u2014 Will NAD+ Interact?<\/h3>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">NAD+ precursors (NR and NMN) have no documented interactions with common supplements like magnesium, omega-3 fatty acids, vitamin D, or B-complex vitamins. They do share metabolic pathways with niacin (vitamin B3), so avoid taking high-dose niacin (over 500mg) alongside NR or NMN. Redundant NAD+ precursor loading doesn&#39;t improve outcomes and may cause flushing. If you&#39;re taking metformin alongside tirzepatide, NAD+ supplementation is particularly beneficial. Metformin inhibits Complex I in the mitochondrial electron transport chain, and NAD+ helps compensate for that inhibition by supporting downstream oxidative capacity.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">The Practical Truth About NAD+ and Tirzepatide Stacking<\/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: NAD+ supplementation won&#39;t replace tirzepatide&#39;s appetite suppression or insulin-sensitizing effects. It&#39;s not a shortcut. What it does is remove a metabolic bottleneck that becomes rate-limiting as weight loss progresses. Most patients lose 15\u201325 pounds in the first 12 weeks on tirzepatide through caloric deficit and glycogen depletion. After that, further weight loss depends on how efficiently the body can oxidize stored fat. And that&#39;s where mitochondrial capacity becomes the constraint. NAD+ doesn&#39;t make fat loss happen faster in the early weeks. It makes sustained fat loss possible in the later months when mitochondrial fatigue would otherwise stall progress.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">The patients who benefit most are those who plateau despite adherence. Still following their caloric targets, still injecting weekly, but weight loss stops or slows to under 0.5 pounds per week. That&#39;s the signature of a metabolic bottleneck, not medication resistance. Adding NAD+ at that stage often restarts progress because it restores the oxidative machinery tirzepatide is relying on. If you&#39;re losing 2+ pounds weekly on tirzepatide without fatigue, NAD+ supplementation is optional. If you&#39;ve stalled or feel exhausted despite adequate sleep and nutrition, it&#39;s worth testing for 8\u201312 weeks.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Tirzepatide works. NAD+ doesn&#39;t enhance the drug. It enhances the mitochondria the drug depends on. That distinction matters.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Combining NAD+ and tirzepatide together isn&#39;t about maximizing short-term weight loss velocity. It&#39;s about sustaining metabolic capacity across the full treatment duration. Tirzepatide mobilizes fat. NAD+ ensures your mitochondria can process it. When both pathways function optimally, weight loss extends beyond the initial glycogen and water loss phase into genuine fat mass reduction that holds after treatment ends. That&#39;s the outcome worth optimizing for. Not the number on the scale at week 12, but the metabolic resilience that keeps it off at month 18.<\/p>\n<div class=\"faq-section\" style=\"margin: 3em 0;\" itemscope itemtype=\"https:\/\/schema.org\/FAQPage\">\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 1em 0; color: #000;\">Frequently Asked Questions<\/h2>\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 you take NAD+ supplements while on tirzepatide?<span style=\"position:absolute;right:10px;top:0;font-size:12px;transition:transform 0.3s;\" class=\"faq-arrow\">\u25bc<\/span><\/summary>\n<div style=\"margin-top:0px;padding-top:0px;\" 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 NAD+ precursors like nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) have no documented drug interactions with tirzepatide or other GLP-1 receptor agonists.

When tirzepatide reduces caloric intake and shifts metabolism toward fat oxidation, mitochondria must convert those fatty acids into ATP through beta-oxidation and the electron transport chain. NAD+ is the rate-limiting cofactor in that process. If NAD+ levels are depleted, mitochondria can&#8217;t efficiently burn fat even during a caloric deficit, leading to plateaus and fatigue.<\/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 best form of NAD+ to take with tirzepatide?<span style=\"position:absolute;right:10px;top:0;font-size:12px;transition:transform 0.3s;\" class=\"faq-arrow\">\u25bc<\/span><\/summary>\n<div style=\"margin-top:0px;padding-top:0px;\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n<p style=\"font-size:18px;line-height:1.8;color:#333;margin:0;\" itemprop=\"text\">Nicotinamide riboside (NR) at 300\u2013500mg daily is the most studied NAD+ precursor in human metabolic trials and has demonstrated safety and efficacy in populations with metabolic syndrome.

This approach isolates GI side effects (which are common during tirzepatide escalation) from potential supplement reactions.

The STEP 1 Extension trial found that patients regained approximately two-thirds of lost weight within one year of stopping semaglutide, and tirzepatide shows similar patterns. NAD+ supports mitochondrial function during active treatment, which may improve fat oxidation efficiency while on medication, but it does not replace the appetite-suppressing and insulin-sensitizing effects tirzepatide provides. Sustained weight maintenance after stopping GLP-1 therapy requires dietary restructuring and, in many cases, transition to a lower maintenance dose rather than 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\">Are there any side effects from combining NAD+ and tirzepatide?<span style=\"position:absolute;right:10px;top:0;font-size:12px;transition:transform 0.3s;\" class=\"faq-arrow\">\u25bc<\/span><\/summary>\n<div style=\"margin-top:0px;padding-top:0px;\" 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+ precursors (NR and NMN) are generally well-tolerated with minimal side effects \u2014 occasional mild nausea or flushing at high doses (over 1000mg daily). These effects are distinct from tirzepatide&#8217;s GI side effects (nausea, vomiting, diarrhea), which occur in 30\u201345% of patients during dose escalation.

The timeline depends on baseline NAD+ depletion \u2014 patients over 50 with pre-existing metabolic syndrome often see faster results than younger, metabolically healthy individuals. NAD+ must rebuild cellular stores and upregulate mitochondrial enzyme expression, which takes time.

Tirzepatide binds to GLP-1 and GIP receptors in the hypothalamus and pancreas, triggering insulin secretion, glucagon suppression, and delayed gastric emptying. NAD+ functions intracellularly as a cofactor in mitochondrial respiration and sirtuin activation, supporting energy production and cellular repair. The two interventions are complementary, not competitive.<\/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 use NAD+ IV therapy instead of oral supplements with tirzepatide?<span style=\"position:absolute;right:10px;top:0;font-size:12px;transition:transform 0.3s;\" class=\"faq-arrow\">\u25bc<\/span><\/summary>\n<div style=\"margin-top:0px;padding-top:0px;\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n<p style=\"font-size:18px;line-height:1.8;color:#333;margin:0;\" itemprop=\"text\">You can, but it&#8217;s not necessary for most patients and offers no sustained advantage over oral NAD+ precursors. NAD+ administered intravenously has a plasma half-life under 30 minutes, meaning blood levels return to baseline within hours. Oral NR and NMN supplementation provides steady NAD+ availability throughout the day by supplying precursors that cells convert to NAD+ as needed. IV therapy is expensive, requires clinical administration, and doesn&#8217;t improve long-term mitochondrial function more effectively than daily oral dosing.<\/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\">Should I take NAD+ if I&#8217;m not experiencing fatigue on tirzepatide?<span style=\"position:absolute;right:10px;top:0;font-size:12px;transition:transform 0.3s;\" class=\"faq-arrow\">\u25bc<\/span><\/summary>\n<div style=\"margin-top:0px;padding-top:0px;\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n<p style=\"font-size:18px;line-height:1.8;color:#333;margin:0;\" itemprop=\"text\">If you&#8217;re losing weight steadily without fatigue, metabolic stalls, or elevated liver enzymes, NAD+ supplementation may be optional. The patients who benefit most are those over 50, those with pre-existing metabolic syndrome, or those who plateau despite adherence to tirzepatide and caloric targets. NAD+ removes a metabolic bottleneck that becomes rate-limiting in mid-to-late treatment phases \u2014 if that bottleneck isn&#8217;t present, supplementation offers minimal added benefit. Consider NAD+ if weight loss stalls after the initial 12\u201316 weeks or if energy levels decline despite adequate sleep and nutrition.<\/p>\n<\/div>\n<\/details>\n<style>.faq-item summary{outline:none;margin-bottom:0!important;padding-bottom:0!important;}.faq-item summary::-webkit-details-marker{display:none;}.faq-item[open] .faq-arrow{transform:rotate(180deg);}.faq-item>div{margin-top:0!important;padding-top:0!important;}.faq-item p{margin-top:0!important;}<\/style>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Combining NAD+ and tirzepatide together enhances metabolic function and weight loss through complementary cellular pathways \u2014 here&#8217;s the science and<\/p>\n","protected":false},"author":6,"featured_media":80939,"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-80940","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\/80940","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=80940"}],"version-history":[{"count":1,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/posts\/80940\/revisions"}],"predecessor-version":[{"id":80941,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/posts\/80940\/revisions\/80941"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/media\/80939"}],"wp:attachment":[{"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/media?parent=80940"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/categories?post=80940"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/tags?post=80940"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
