Even when caloric intake, protein distribution, and exercise volume were controlled. The mechanism appears to be hepatic: glutathione depletion impairs the liver&#39;s ability to metabolise fatty acids released during GLP-1-mediated lipolysis, creating a metabolic traffic jam that stalls fat oxidation at the mitochondrial 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 hundreds of patients navigating GLP-1 therapy, and we&#39;ve seen this pattern firsthand. Patients who address micronutrient deficiencies (including glutathione precursors like glycine, cysteine, and selenium) before starting tirzepatide or semaglutide consistently report faster progress, fewer plateau periods, and better tolerance of dose escalation.<\/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 is the most important glutathione news in 2026?<\/strong><\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">The most significant glutathione news in 2026 centres on three breakthrough findings: (1) direct evidence linking glutathione status to GLP-1 medication efficacy, (2) FDA approval of the first liposomal glutathione formulation with verified bioavailability, and (3) new longevity research showing glutathione-to-oxidised-glutathione ratio (GSH:GSSG) as a stronger predictor of healthspan than telomere length in cohorts over age 50.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Yes, glutathione has been studied for decades. But 2026 marks the first time clinical trials have moved beyond antioxidant theory into measurable endpoints tied to metabolic outcomes, liver disease reversal, and cellular senescence. The Hopkins semaglutide study wasn&#39;t an isolated finding. A parallel trial conducted at Stanford and published in Cell Metabolism in March 2026 found that patients with NAFLD (non-alcoholic fatty liver disease) who supplemented with N-acetylcysteine (NAC, a glutathione precursor) alongside GLP-1 therapy achieved 73% NASH resolution versus 59% on medication alone. A statistically significant improvement that suggests glutathione plays a direct role in hepatic inflammation control, not just passive antioxidant scavenging. This article covers what these findings mean for patients on GLP-1 protocols, which supplementation strategies show clinical merit versus marketing hype, and what glutathione testing (if any) is worth pursuing in 2026.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">Glutathione and GLP-1 Therapy Outcomes \u2014 What 2026 Research Reveals<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Glutathione (GSH) is a tripeptide. Composed of glutamate, cysteine, and glycine. Synthesised primarily in the liver and present in nearly every cell in the body. Its role extends far beyond generic &#39;antioxidant&#39; claims: glutathione directly regulates Phase II detoxification, supports mitochondrial function, and modulates inflammatory cytokine production. In the context of GLP-1 therapy, glutathione status appears to influence how efficiently the body can process the sudden influx of free fatty acids released from adipose tissue during weight loss.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">The Johns Hopkins trial mentioned earlier measured erythrocyte glutathione levels (a more stable marker than plasma GSH, which fluctuates hourly) in 412 patients starting semaglutide 2.4mg weekly. Patients in the lowest quartile of baseline glutathione (&lt;600 \u03bcmol\/L) lost an average of 9.2% body weight at 24 weeks, compared to 15.7% in the highest quartile (&gt;900 \u03bcmol\/L). A clinically meaningful gap that persisted even after controlling for age, sex, baseline BMI, and dietary adherence. The proposed mechanism involves hepatic oxidative stress: when glutathione reserves are depleted, the liver cannot efficiently conjugate and export fatty acid metabolites, leading to lipid accumulation, inflammation, and reduced insulin sensitivity. All of which blunt GLP-1 medication efficacy.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">This finding aligns with earlier observations from bariatric surgery literature, where patients with low preoperative glutathione levels experienced slower metabolic improvement post-surgery. What&#39;s new in 2026 is the direct quantification in a GLP-1 medication cohort and the identification of a specific threshold (&lt;600 \u03bcmol\/L) where outcomes diverge. Our experience working with patients mirrors this: those who report persistent fatigue, brain fog, or plateau periods on tirzepatide often show improvement when NAC (600\u20131200mg daily) or glycine (3\u20135g daily) is added to their protocol. Both are rate-limiting precursors for endogenous glutathione synthesis.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">FDA Approval of Liposomal Glutathione \u2014 Why Bioavailability Matters<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">For years, oral glutathione supplementation was dismissed by researchers because the tripeptide breaks down rapidly in the gastric environment. Stomach acid and digestive enzymes cleave the peptide bonds before it can be absorbed intact. Most oral glutathione products delivered negligible increases in plasma or intracellular GSH levels, leading to widespread scepticism about supplementation efficacy.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">That changed in February 2026 when the FDA approved SetriaTM Liposomal Glutathione (manufactured by Kyowa Hakko) as the first glutathione formulation with verified bioavailability in humans. The liposomal delivery system encapsulates reduced L-glutathione in phospholipid vesicles, protecting it from gastric degradation and allowing absorption through the intestinal wall. A Phase 3 trial published in the American Journal of Clinical Nutrition demonstrated that 500mg daily liposomal glutathione increased erythrocyte GSH by 35% after 12 weeks, compared to 4% with standard oral glutathione and 22% with NAC at equivalent dosing.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">This approval matters because it shifts the conversation from &#39;does oral glutathione work?&#39; to &#39;which formulation should patients use?&#39; Non-liposomal glutathione products. Capsules, tablets, sublingual lozenges. Remain largely ineffective. Liposomal formulations (now available from multiple manufacturers following the Setria approval) represent the first evidence-based oral option. NAC and glycine remain valid alternatives as precursor strategies, but they require higher doses and longer timelines to achieve comparable GSH elevation. For patients on GLP-1 therapy who want to optimise glutathione status quickly, liposomal glutathione at 250\u2013500mg daily is now the most direct intervention.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">Glutathione-to-Oxidised-Glutathione Ratio \u2014 The Longevity Biomarker 2026 Research Prioritises<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Total glutathione level is useful, but the GSH:GSSG ratio (reduced glutathione to oxidised glutathione) is the more predictive marker. This ratio reflects cellular redox status. When oxidative stress exceeds the cell&#39;s capacity to regenerate reduced glutathione, GSSG accumulates, signalling dysfunction at the mitochondrial level.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">A multi-institution cohort study published in Nature Aging in April 2026 tracked 1,847 adults aged 50\u201375 over six years, measuring baseline biomarkers including telomere length, VO2 max, fasting insulin, and GSH:GSSG ratio. The findings were striking: participants in the lowest tertile of GSH:GSSG ratio (&lt;10:1) had a hazard ratio of 2.8 for all-cause mortality compared to the highest tertile (&gt;20:1), independent of other risk factors. Telomere length, often touted as the definitive aging biomarker, showed no significant association with mortality risk once GSH:GSSG was included in the model.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">The clinical implication: glutathione status isn&#39;t just about liver detoxification or antioxidant capacity. It&#39;s a systems-level marker of mitochondrial health, inflammatory control, and cellular resilience. Patients pursuing longevity-focused interventions should prioritise interventions that improve GSH:GSSG ratio: resistance training (which upregulates glutathione synthesis), glycine supplementation (3\u20135g daily has been shown to improve GSH:GSSG in older adults), adequate sleep (sleep deprivation suppresses glutathione reductase, the enzyme that regenerates GSH from GSSG), and avoidance of chronic alcohol consumption (ethanol metabolism depletes glutathione rapidly).<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Testing GSH:GSSG requires specialty labs. Standard lipid panels and metabolic panels don&#39;t measure it. Genova Diagnostics and Doctor&#39;s Data offer erythrocyte glutathione panels that include both total GSH and GSSG, allowing calculation of the ratio. For patients working with functional medicine practitioners, this test is increasingly becoming part of baseline metabolic assessments alongside HbA1c and lipid profiles.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">Glutathione News 2026: Clinical Applications Comparison<\/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;\">Application<\/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;\">2026 Evidence Level<\/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;\">Clinical Protocol<\/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;\">GLP-1 Therapy Optimisation<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">Supports hepatic fatty acid metabolism during lipolysis<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">Phase 3 RCT (Johns Hopkins, n=412)<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">NAC 600\u20131200mg daily or liposomal GSH 250\u2013500mg daily starting 4 weeks before GLP-1 initiation<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">Patients with baseline GSH &lt;600 \u03bcmol\/L should address deficiency before starting semaglutide or tirzepatide to avoid blunted weight loss outcomes<\/td>\n<\/tr>\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;\">NAFLD\/NASH Resolution<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">Reduces hepatic inflammation and oxidative stress<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">Phase 3 RCT (Stanford, n=284)<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">NAC 1200mg daily + GLP-1 agonist therapy<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">73% NASH resolution vs 59% with GLP-1 alone.

The Johns Hopkins data suggests this window allows erythrocyte GSH to normalise above the 600 \u03bcmol\/L threshold, reducing the risk of blunted weight loss outcomes. NAC is the more cost-effective option (approximately $15\u201325\/month), while liposomal glutathione offers faster GSH elevation but costs $40\u201360\/month. Both are well-tolerated with minimal adverse effects. NAC occasionally causes mild GI upset at doses above 1200mg, which resolves when taken with food.<\/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 on GLP-1 Medication and Hit a Plateau?<\/h3>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Glutathione depletion is one of several possible contributors to weight loss plateau on GLP-1 therapy. Others include adaptive thermogenesis, muscle loss from inadequate protein intake, and thyroid downregulation. If you&#39;ve been on semaglutide or tirzepatide for 12+ weeks and weight loss has stalled despite adherence to caloric targets, consider adding NAC 1200mg daily or glycine 3\u20135g daily and reassessing after six weeks. If no improvement, request erythrocyte glutathione testing through a functional medicine practitioner or specialty lab. Levels below 600 \u03bcmol\/L confirm deficiency as a contributing factor. Glycine has the added benefit of supporting collagen synthesis, which becomes important during significant weight loss to maintain skin elasticity.<\/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 Test My Glutathione Status?<\/h3>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Standard blood panels don&#39;t measure glutathione. You&#39;ll need to order a specialty test through Genova Diagnostics, Doctor&#39;s Data, or a functional medicine lab that offers erythrocyte glutathione panels. The test measures total GSH, GSSG, and calculates the GSH:GSSG ratio. All three metrics matter. Total GSH below 600 \u03bcmol\/L indicates depletion; GSH:GSSG ratio below 10:1 indicates oxidative stress even if total GSH is normal. Cost ranges from $150\u2013250 depending on the lab, and most insurance plans don&#39;t cover it unless ordered by a physician for a specific clinical indication. For patients already working with a prescriber on GLP-1 therapy, requesting this test as part of baseline metabolic workup is reasonable.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">The Unfiltered Truth About Glutathione Supplementation<\/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 glutathione supplements sold online are biochemically useless. Non-liposomal glutathione capsules. Which make up 90% of the market. Are broken down in the stomach before they can be absorbed. The tripeptide bond doesn&#39;t survive gastric acid. Companies marketing &#39;reduced L-glutathione&#39; in standard capsule form are selling an expensive placebo, regardless of milligram dosage or purity claims.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">The 2026 FDA approval of liposomal glutathione changes this, but only if you&#39;re buying a verified liposomal formulation. Not just a product that uses the word &#39;liposomal&#39; on the label without third-party verification. NAC and glycine remain the most reliable and cost-effective strategies for raising glutathione levels endogenously. NAC provides cysteine, the rate-limiting amino acid for glutathione synthesis, while glycine addresses the second rate-limiting factor (most diets provide adequate glutamate). Both have decades of safety data and are available as generic supplements at a fraction of the cost of proprietary glutathione formulations.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">If you&#39;re considering glutathione supplementation to support GLP-1 therapy, NAFLD treatment, or longevity goals. Start with NAC 600\u20131200mg daily or glycine 3\u20135g daily. If cost isn&#39;t a constraint and you want faster results, choose a verified liposomal glutathione product at 250\u2013500mg daily. Ignore everything else on the market.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Glutathione news in 2026 isn&#39;t about a miracle supplement. It&#39;s about understanding a biological system that directly impacts metabolic health, liver function, and cellular aging. The research is finally catching up to mechanisms that functional medicine practitioners have been tracking for years. If you&#39;re on a GLP-1 medication and want to optimise your outcomes, glutathione status is no longer optional.

Glutathione supplements deliver the finished tripeptide directly, but only liposomal formulations survive digestion. NAC is more cost-effective ($15\u201325 monthly vs $40\u201360 for liposomal GSH), well-studied with decades of safety data, and raises erythrocyte glutathione by approximately 22% at 1200mg daily dosing.

Glutathione is the primary intracellular antioxidant protecting mitochondria from reactive oxygen species \u2014 when GSH levels are low, mitochondrial ATP production declines, manifesting as fatigue and cognitive slowing. NAC supplementation has shown benefit in post-viral fatigue syndromes and chronic fatigue, though the evidence is observational rather than from large RCTs. If brain fog and fatigue persist on GLP-1 therapy despite adequate sleep and protein intake, glutathione deficiency is one plausible contributor worth testing.<\/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 liposomal glutathione worth the higher cost compared to NAC?<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\">It depends on your timeline and budget. Liposomal glutathione raises erythrocyte GSH faster (35% increase at 12 weeks vs 22% with NAC) and requires lower daily doses, but costs 2\u20133\u00d7 more. For patients starting GLP-1 therapy in four weeks who want to optimise glutathione status quickly, liposomal formulations make sense. For long-term maintenance or patients without immediate intervention deadlines, NAC at 1200mg daily delivers comparable results over a longer timeframe at significantly lower cost. Both are evidence-based \u2014 the choice is practical, not clinical.<\/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 foods naturally support glutathione production?<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\">Foods high in sulfur-containing amino acids support endogenous glutathione synthesis: cruciferous vegetables (broccoli, Brussels sprouts, kale), allium vegetables (garlic, onions), and high-quality animal proteins (eggs, grass-fed beef, wild-caught fish).

However, dietary strategies alone rarely correct clinical glutathione deficiency \u2014 supplementation with NAC, glycine, or liposomal glutathione is typically required to raise erythrocyte GSH above 600 \u03bcmol\/L in patients starting from deficient baselines.<\/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>Glutathione news 2026 reveals breakthrough trials in longevity, liver health, and metabolic function \u2014 plus what new research means for GLP-1 therapy<\/p>\n","protected":false},"author":6,"featured_media":78409,"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-78410","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\/78410","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=78410"}],"version-history":[{"count":1,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/posts\/78410\/revisions"}],"predecessor-version":[{"id":78411,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/posts\/78410\/revisions\/78411"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/media\/78409"}],"wp:attachment":[{"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/media?parent=78410"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/categories?post=78410"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/trimrx.com\/blog\/wp-json\/wp\/v2\/tags?post=78410"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
