Does EsoRepair work? The eleven ingredients, the amounts on the label and the amounts in the brand FAQ
Quick answer
Does EsoRepair work? No trial of EsoRepair itself was found, and the brand’s “4,000 people tracked” figures have no published source. The nearest trial, of a hyaluronic acid and chondroitin gel added to a PPI four times a day, lifted symptom scores by 3 points or more in 52.6% against 32.1% on placebo over two weeks in 154 people. EsoRepair is a 2 mL liquid taken once a day, with 22.5 mg of hyaluronic acid and 11.25 mg of alginate on its label. The brand’s FAQ lists higher amounts than the label for eight ingredients.

EsoRepair is a 60 mL glass dropper bottle of liquid from NanoRevive, sold for heartburn and throat comfort and described as an “esophageal and stomach” formula. It lists eleven actives, each with its own amount, and the brand says they coat and support the esophageal lining. What sets it apart is the format, and that the brand’s FAQ and its Supplement Facts panel print different amounts. This page sets out both, the trials behind each ingredient, who is behind the brand, and the billing terms.
What EsoRepair is, and what the label says
A serving is 2 mL (two droppers), 30 servings to the bottle. The panel lists the amounts below; the same panel appears on the brand site and on Amazon. The brand’s FAQ, under “What are the 11 active ingredients,” says each is “dosed to match levels used in published scientific research” and lists these figures:
| Ingredient | Supplement Facts panel | Brand FAQ |
|---|---|---|
| Zinc-L-carnosine | 75 mg | 75 mg |
| DGL licorice extract | 90 mg | 150 mg |
| Chondroitin sulfate | 90 mg | 50 mg |
| L-glutamine | 45 mg | 250 mg |
| Slippery elm mucilage | 40 mg | 200 mg |
| Hyaluronic acid | 22.5 mg | 100 mg |
| Marshmallow root 10:1 | 22.5 mg | 200 mg |
| Quercetin | 22.5 mg | 125 mg |
| Sodium alginate | 11.25 mg | 30 mg |
| Aloe vera 200:1 | 4.5 mg | 10 mg |
| Vitamin D3 | 50 mcg (2,000 IU) | 2,000 IU |
The panel is the legal label; the page’s “Formulation” block uses the panel’s numbers. The brand’s About page gives yet another split of the zinc-L-carnosine (16 mg zinc and 59 mg carnosine) against the panel image (10 mg and 65 mg). One Trustpilot reviewer wrote that the product changed in September 2026 with no update on the box. Ads and pages say “nano”, “liposomal” and “up to 98% absorption”; the panel shows no liposomal ingredient, and we found no particle-size or absorption data.
The trial of the product itself
We found none. PubMed and ClinicalTrials.gov return nothing for EsoRepair or NanoRevive. An advertorial page says “4,000+ people tracked over 90 days” and that 84% of 3,500-plus participants reported easier swallowing, with no design, source or publication given.
The evidence for the ingredients
Hyaluronic acid and chondroitin. The closest-matched trial is of Esoxx, a hyaluronic acid-chondroitin sulfate gel in a bioadhesive carrier, added to a PPI in 154 people with non-erosive reflux for two weeks: 52.6% against 32.1% on placebo had a symptom-score fall of 3 points or more (P<0.01) (Savarino et al., 2017). It was a 10 mL stick four times a day with a PPI, not 2 mL once a day.
Alginate. A meta-analysis of 14 trials in 2,095 people found alginate products beat placebo or antacids (OR 4.42, 95% CI 2.45 to 7.97) and did not differ significantly from PPIs or H2 blockers (OR 0.58, 0.27 to 1.22) (Leiman et al., 2017). Those were antacid-alginate suspensions: UK Gaviscon labels declare 500 mg or 1,000 mg of sodium alginate per 10 mL dose, and EsoRepair’s 11.25 mg is 1% to 2% of that.
Zinc-L-carnosine. We found no trial in adult heartburn or reflux. Human trials are in other conditions, such as radiation esophagitis in lung-cancer patients (Yanase et al., 2015), and a review notes it is “not an anti-secretory, antacid or raft-forming agent” (Efthymakis & Neri, 2022). The H. pylori trial used 150 mg a day; the brand site’s direction gives 75 mg.
DGL licorice. GutGard, a branded extract, helped functional dyspepsia at 150 mg a day for 30 days (Raveendra et al., 2012) and reflux symptoms in a 200-person trial (Raj et al., 2025). EsoRepair’s 90 mg is 60% of the dyspepsia dose, and the label does not name GutGard.
The rest. An aloe syrup pilot in 79 people used 10 mL a day against omeprazole or ranitidine (Panahi et al., 2015); EsoRepair has 4.5 mg of aloe extract. The brand’s “ninety percent felt relief within ten minutes” for marshmallow root comes from a survey of cough, not reflux (Fink et al., 2018). Its vitamin D3 and quercetin citations are rat and cell studies. Two of the brand’s PubMed links, on polaprezinc and aloe, open unrelated papers.
How to take EsoRepair
The brand site says 2 mL once a day, held under the tongue for about 30 seconds and swallowed, or mixed into half a cup of water and sipped slowly; bedtime is allowed. Amazon’s directions differ: 2 mL in water twice a day before meals, or 4 mL once a day. At that rate a bottle lasts 15 days. No time to effect has been studied.
Side effects and who should not take it
The brand asks anyone taking PPIs, H2 blockers, blood thinners or immunosuppressants to consult a doctor first, says it is not a replacement for prescribed medication, and says it is not intended to manage Barrett’s esophagus. We found no pregnancy, breastfeeding or age warning on the label images or pages, and no long-term safety data, though the FAQ says it is safe for long-term use. Vitamin D3 is 250% of the Daily Value. Trustpilot reviewers report nausea, burping and, in a few cases, worse reflux or laryngopharyngeal reflux symptoms.
Who is behind it, and how it is advertised
The site is operated by Seven Trends LLC, listed at 16192 Coastal Highway, Lewes, Delaware. The Better Business Bureau states that this is a registered-agent address, not the business’s physical location, and that the company appears to be located outside the US. We found no owner, officer or manufacturer named on the site, Amazon or the BBB.
Of the first 30 active Meta ads we read for the site, 26 name EsoRepair, run under page names including “The Gut Lining Lab”, “Gastroenterologist Review” and “Diane R. Olson ENT”. An ad from the last page begins with a nurse who “wrote it down hundreds of times over twenty-two years on a gastroenterology floor”. The advertorial it leads to is bylined “Dr. Diane R. Olson, ENT Doctor”, with 23 years of practice and a past as a GI specialist. We searched the federal NPI registry for first name Diane and last name Olson and got six individual providers: a counselor, two social workers, two registered nurses and a dietitian, none a physician and none with the middle initial R. A web search for the name with ENT, nurse and EsoRepair found no match. The registry only covers providers who hold an NPI, so this is not proof either way. The page’s testimonials are first names and ages, and its comment box is labeled “Draft review copy”.
What the reviews say
Amazon shows 3.9 from 1,003 ratings (61% five-star, 16% one-star), review text behind a sign-in. Trustpilot shows 4.5 from 296 reviews (81% five-star, 12% one-star); the profile was claimed in November 2025 and the company replied to 81% of negative reviews. The brand’s own site shows 4.8 from “10,000+ reviews” and its homepage cards say “Showing our 5 star reviews”. The BBB lists the company as Not Rated. Reviewers praise heartburn and night-time reflux easing, the easy dropper and a tolerable taste. They complain of refund and support delays, no effect or worse symptoms, and subscription charges.
Subscription and refund terms
The product page loads with Subscribe & Save selected: $48.99 for one bottle every four weeks. The refund policy states a 90-day, 100% guarantee with conditions: a $2 non-refundable fee, one claim per customer or household, a request within 90 days of delivery, no coverage for Amazon or TikTok Shop purchases, and a return label sent only if the return is accepted. The subscription page says the card is charged at the start of each cycle, that cancelling or skipping must happen at least 24 hours before billing, and that “NanoRevive does not offer a general money-back guarantee,” with refunds only for unshipped, damaged, incorrect or unauthorized charges. The same page includes a block headed “Compliance obligations (internal)”.
Recent Trustpilot reviews describe being charged after cancelling, a shipment arriving after a stop request, and a subscription the buyer says they did not choose. Others report refunds after emails and a phone call. A single bottle can be bought one time ($69.99) or from Amazon ($59.90), where the brand’s 90-day policy does not apply.
Cost
One bottle is $69.99 one time ($2.33 a day); three are $62.84 each ($2.09) and six are $57.13 each ($1.90). On subscription it is $48.99 ($1.63), $43.99 on three ($1.47) and $39.99 on six ($1.33). Amazon lists $59.90 ($2.00 a day at the label serving, or $3.99 at Amazon’s twice-daily direction).
Who EsoRepair is for
- Someone who wants a liquid with the eleven listed actives and has weighed the panel against the FAQ.
- A person not taking the medicines the brand lists, who would buy a single bottle rather than the selected plan.
The reflux guide sets out the options with their own trials. The catalog pages for them are Hartspan KHelp (an alginate), Doctor’s Best PepZin GI (zinc-L-carnosine) and Natural Factors Chewable DGL.

Common questions
Does EsoRepair work?
No trial of EsoRepair itself was found. Hyaluronic acid with chondroitin, alginate, zinc-L-carnosine and a licorice extract each have studies, but of other products or at other doses, and the brand cites a cough survey for marshmallow root and rat or cell studies for vitamin D3 and quercetin. Reviews are mixed: 4.5 on Trustpilot from 296 reviews and 3.9 on Amazon from 1,003 ratings.
What is in EsoRepair, and why does the FAQ list different amounts from the label?
The Supplement Facts panel lists 2 mL of liquid with zinc-L-carnosine 75 mg, DGL 90 mg, chondroitin sulfate 90 mg, L-glutamine 45 mg, slippery elm mucilage 40 mg, hyaluronic acid 22.5 mg, marshmallow root 22.5 mg, quercetin 22.5 mg, sodium alginate 11.25 mg, aloe vera 4.5 mg and vitamin D3 50 mcg. The brand’s own FAQ lists higher amounts for eight of these, for example glutamine 250 mg and slippery elm 200 mg. The panel is the label as filed; we found no explanation for the difference.
EsoRepair vs omeprazole: can it replace a PPI?
The brand says it is a supplement and not a replacement for prescribed medication. The closest trial, of a hyaluronic acid and chondroitin product, tested it added to a PPI four times a day for two weeks, not instead of one. No study compares EsoRepair with a PPI. For other options see the reflux guide.
Is EsoRepair safe, and what are the side effects?
The brand asks people taking PPIs, H2 blockers, blood thinners or immunosuppressants to check with a doctor first. We found no pregnancy or breastfeeding warning on the label images or pages, and no long-term safety data for the finished product. A few Trustpilot reviewers report nausea, burping or worse reflux after starting it.
How do you take EsoRepair?
The brand site says 2 mL (two droppers) once a day, held under the tongue for about 30 seconds and swallowed, or mixed into half a cup of water and sipped over one to two minutes. Amazon prints a different direction: 2 mL twice a day before meals, or 4 mL once a day. At the Amazon direction a 60 mL bottle lasts 15 days rather than 30.
How much does EsoRepair cost?
One 60 mL bottle is $69.99 one time on the brand site ($2.33 a day), $48.99 on a 4-week subscription ($1.63 a day), and $59.90 on Amazon. Three bottles are $62.84 each one time or $43.99 on subscription, and shipping is free. The page loads with Subscribe & Save selected.
Who runs NanoRevive, and how do cancellation and refunds work?
NanoRevive is operated by Seven Trends LLC at a Delaware registered-agent address; the Better Business Bureau says the business appears to be located outside the US, and we found no owner or manufacturer named. The brand states a 90-day money-back guarantee with a $2 fee and one claim per household, and its subscription page says to cancel at least 24 hours before billing and that it does not offer a general money-back guarantee on subscriptions. Trustpilot reviewers report charges after cancelling and refund replies that took weeks, while others report refunds arriving after repeated emails.
