Renew31 Reviews (2026)

A once-a-day gummy sold as plant-retinol skin care from the inside. We checked what is in it, what the page claims, and the one ingredient that deserves a closer look before you swallow it.

Reviewed by the Renew31 Reviews editorial team · updated October 2026

Where we landed

Bottom line: Renew31 is a 30-count gummy built on five named ingredients: Bacillus coagulans, chicory root inulin, babchi powder, lion’s mane, and ginger. The probiotic and prebiotic have real research on digestion, which is also the label’s most defensible claim. The rest of the pitch is weaker. No ingredient has a dose, babchi is presented as “plant-based retinol” although the research is on a different, purified compound applied to skin, and two of the three “you save” figures do not match the prices beside them.

Pros and cons

Working for it

  • All five ingredients are named, and the page says in plain words what each is supposed to do.
  • Bacillus coagulans is a real, researched spore probiotic, and “supports digestion” is the best-supported claim on the label.
  • One gummy a day with simple directions, and no stimulants claimed.
  • Per-bottle prices are shown as real numbers and are consistent ($79, $69, $49), with free US shipping on the 3- and 6-bottle packs.
  • The page advises showing the label to your doctor if you take medication.
  • A one-time purchase is stated, with no automatic renewals.

Working against it

  • No dose for any ingredient, no Supplement Facts panel, and no probiotic count despite “high-concentration probiotics.”
  • Babchi powder is sold as plant retinol. Its seed has documented liver and skin-sensitivity reports, yet the page says no significant side effects have been reported.
  • The “you save” labels for the 2- and 3-bottle packs do not match the prices shown.
  • The first bonus promises to “eliminate” varicose veins in up to six weeks without surgery.
  • Hero copy promises results “in just a few weeks,” the FAQ recommends a six-month course, and the refund window is 60 days.
  • A section heading reads “Do your Derman Clean order,” the name of another product.
  • No company is named, and the legal pages are hosted on an unrelated domain.

What Renew31 is

Renew31 is a chewable gummy dietary supplement sold in bottles of 30. The bottle is raspberry-pink with a lotus mark, the line “Nature’s Nutriwave,” and the claims “Promote Skin Vitality” and “Supports Digestion.” The page aims at women who have “tried everything on the outside” and pitches Renew31 as a way to smooth skin, restore hydration, and “reactivate” collagen without creams or procedures. The directions are one gummy a day, about 30 minutes before a morning or afternoon meal, with a full glass of water.

It is sold as a supplement, not a medicine. The page’s own footer says it is not intended to diagnose, treat, cure, or prevent any disease.

How we reviewed it. We read the product page’s text, which covered the ingredient write-ups, prices, bonuses, and FAQ, and we examined the bottle photography and a graphic supplied with the product materials. The reference list and a few other panels are images we could not read, and we did not open the checkout or the legal pages. We searched for independent coverage and complaints and found none specific to Renew31. We did not buy or test the product.

The five ingredients

The page gives each ingredient a short pitch. None has an amount beside it, and the probiotic has no live-cell count. Here is each claim next to what we found.

The five named ingredients: the page's claim, what research shows, and the amount disclosed
IngredientWhat the page saysWhat we foundAmount
Bacillus coagulans“Colonizes” the gut, rebalances flora, and clears the redness and dullness that inflammation causes.A spore-forming probiotic with real research, mostly on digestive symptoms. Probiotics generally pass through rather than settle permanently, and we know of no strong human trial showing this strain improves skin tone. Strain and live count are not given.Not shown
Chicory root inulinFeeds good bacteria and improves absorption of the nutrients skin needs for hydration.A prebiotic fiber that does feed gut bacteria and can cause gas or bloating in larger amounts. The jump to skin hydration is the page’s claim, not something it supports.Not shown
Babchi powder“A natural source of bakuchiol,” the plant-based retinol, renewing skin without irritation.See the next section. This is the ingredient to understand before buying.Not shown
Lion’s mane powderAn adaptogen that keeps cortisol down and inflammation low, so skin recovers elasticity.A mushroom with small human studies on cognition and mood. We are not aware of a human trial linking it to cortisol or skin elasticity.Not shown
Ginger root extractAnti-inflammatory; supports the liver in clearing “toxins” that show up as blemishes and adult acne.Ginger has research on nausea and some inflammation markers. The detox route to clearer skin is not an established mechanism, and we are not aware of evidence that ginger clears acne.Not shown

The collagen claim. The hero says Renew31 will “reactivate your body’s natural collagen production.” None of the five ingredients is a collagen-supporting nutrient such as vitamin C or collagen peptides, and the only study list is an image we could not read. Treat it as an unsupported claim until you see the evidence.

Babchi is not bakuchiol

The page describes babchi powder as “a natural source of bakuchiol,” known as “plant-based retinol,” which stimulates skin renewal “without the irritation” of retinoids. Two separate things are being blended together here.

What the research actually tested

Bakuchiol is one compound found in the seeds of Psoralea corylifolia, the babchi plant. The studies that compared bakuchiol with retinol used purified bakuchiol in creams applied to the skin. They did not test swallowing babchi seed powder, and nothing in them shows that eating the powder delivers bakuchiol to the skin or produces retinol-like effects.

What the seed itself is known for

The same seeds contain psoralens, which are photosensitizing compounds. The US National Institutes of Health’s LiverTox database notes that case reports of acute liver injury have followed the use of Psoralea corylifolia seeds, powder, and teas, and rates it a probable rare cause of clinically apparent liver injury. A review of 84 published cases found that most were liver damage (about 56%) or light-triggered contact dermatitis (about 38%). A published case report describes severe liver failure in a woman who took babchi seeds for vitiligo.

What this does and does not mean. Those reports involve medicinal amounts of seeds, powders, and teas. Renew31 does not say how much babchi a gummy contains, or whether “babchi powder” is whole-seed powder or a purified, psoralen-free extract. So we cannot say Renew31 is dangerous. We can say that the page’s answer to “Is Renew31 safe for me?” is a flat “Yes,” adding that “no significant side effects have been reported,” and that is more certain than the evidence allows.

Before you buy, it is reasonable to ask the seller whether the babchi is seed powder or an extract, how much each gummy contains, and whether it has been tested for psoralens. If you have liver disease, take medicines processed by the liver, are pregnant or nursing, or spend time in strong sun or tanning beds, speak to a doctor first. Yellowing of the skin or eyes, dark urine, severe itching, or unusual persistent tiredness or abdominal pain after starting any supplement are reasons to stop it and get medical care.

The claims, checked

“In just a few weeks.” The hero says Renew31 will smooth the signs of time “in just a few weeks of use.” The FAQ says most customers choose the six-bottle kit, “a full 6-month treatment,” because that is the ideal time for the ingredients to work. Both cannot be the plan, and the refund window is only 60 days, so it ends long before a six-month course does.

“Rigorously tested” and “no significant side effects.” The FAQ says all ingredients are rigorously tested for quality and safety. We found no test results, lab name, or certificate anywhere. The absence of reported side effects from a seller is not evidence of safety, especially for a product with no independent reviews we could find.

The gut-skin idea. The link between gut bacteria and skin is a real area of research. But the evidence that a probiotic gummy firms or smooths skin in people is limited and strain-specific, and Renew31 names only a species.

Page details that do not hold up

  • Another product’s name. The heading above the second set of pricing boxes reads “Don’t waste time, do your Derman Clean order before stock runs out.” Derman Clean is not this product.
  • An unsourced stat. “96% of customers order 6 bottles” has no source, and the same wording appears on pages for other supplements we have reviewed.
  • Urgency. Two countdown timers read 30:00 beside the prices, and the FAQ says stock is limited because of “small-batch production.” We cannot tell whether the timers reset for every visitor.

The “Your Path to Radiance” graphic

The materials include a three-step illustration. Its title is misspelled “Radiincs,” “Step 1” appears twice with different captions, and Step 2 promises an “advanced delivery system” in a garbled sentence that the product page never mentions. Step 1 pictures a doctor with a tablet beside the bottle, although no physician is credited or quoted anywhere, and Step 3 shows a rising bar chart with no data. It looks generated rather than designed, and none of it is evidence.

The graphic supplied with the product materials. We checked its captions, not the artwork.

A crowded family of look-alikes

Renew31’s ingredient set (Bacillus coagulans, inulin, babchi, lion’s mane) is a trimmed version of a family of gut-and-skin gummies sold under other names, including Neotonics and PrimeBiome, which add ingredients such as fenugreek, lemon balm, or dandelion. Reviews and complaints for those products are about different formulas, so do not assume they apply to Renew31, or the reverse.

Pricing, and the savings that do not add up

The page sells three packages. The per-bottle prices are consistent and every “regular” total is a clean multiple of $179. The “you save” labels are another matter. We checked each against the totals printed beside it:

Renew31 packages, the page's savings claims, and the actual difference
PackagePer bottleTotal“Regular”Page says you saveActual difference
2 bottles, 60-day supply$79$158 plus shipping$358$90$200 Does not match
3 bottles, 90-day supply$69$207, free US shipping$537$360$330 Does not match
6 bottles, 180-day supply$49$294, free US shipping$1,074$780$780 Matches

The page also advertises “65% off.” Against the brand’s own $179 reference, the three packages are actually about 56%, 62%, and 73% off, so 65% matches none of them. Mismatched labels may simply be sloppy copy, but you should not rely on them. The $179 “regular” price is the brand’s own figure, and we saw no evidence it was ever the selling price. Judge the offer by what you pay per bottle ($49 to $79), and confirm the total at checkout, because the 2-bottle pack adds shipping.

The supply labels are consistent with one 30-count bottle per 30 days.

Accepted payment methods

Our order link runs through an affiliate tracking address, so check the seller on the order page and your receipt. We found no authorized retail listing, so a listing elsewhere would be a reseller outside any guarantee.

The six “free” bonuses

Orders of three or six bottles include six digital guides, each shown with a crossed-out value that adds up to $358. The values are the brand’s own figures. We did not read the guides, and most are not about skin:

$67
Stretch Mark Eraser Guide coverStretch Mark Eraser Guide
$59

$67
Renova Flora Protocol guide coverRenova Flora Protocol
$77
Flat Butts and Defined Thighs guide coverFlat Butts and Defined Thighs
$49
Personalized Usage Guide coverPersonalized Usage Guide
$39

The page describes the first guide as a protocol to “reduce and eliminate” varicose veins “in up to 6 weeks,” painlessly and without surgery, and the second as a way to “eliminate” stretch marks with home recipes. We could not substantiate either claim. Varicose veins that hurt, swell, or change should be seen by a doctor, and promising to eliminate them with a guide is a medical claim we would not trust. The fourth guide promises to “accelerate fat burning.” Only the usage guide relates directly to the supplement.

The guarantee

60-day money-back guarantee badge

The FAQ calls Renew31 “backed by an unconditional 60-day guarantee,” and then, in the same answer, says you qualify if “after at least 30 days of use” you are not satisfied. A guarantee with a 30-day minimum is not unconditional, and the two statements side by side tell you the condition is real.

Because the page also recommends six months of use, 60 days covers only a third of the course it asks you to follow. We could not open the Returns page, which is hosted on a separate domain (see below), so we cannot say how the days are counted, who pays return shipping, or what a refund request involves. Get the terms in writing before you order, keep your confirmation email, and note the date your bottle arrives.

Who is behind Renew31

The bottle carries the line “Nature’s Nutriwave,” but the page itself says only “Copyright 2026 by Renew31.” It names no company, address, or phone number, and its contact email is hidden behind a protection script. The Terms of Service, Privacy Policy, Returns, Disclaimer, and Contact links all lead to a separate address, lp.institutoexperience.com.br, rather than to a page on the brand’s own site. Shared hosting is common, but it leaves the question of who stands behind the product unanswered.

The page says Renew31 is produced in the United States in an FDA-registered facility using “imported natural ingredients” in small batches. Registration is an administrative listing, not FDA approval, and we found no lab report or certificate of analysis.

Side effects and who should be careful

Beyond the babchi question, the other four ingredients are generally gentle but not risk-free:

  • Inulin commonly causes gas, bloating, or loose stools, especially at the start or in larger amounts.
  • Probiotics are generally well tolerated, but people with weakened immune systems or serious illness should ask a doctor first.
  • Lion’s mane is a mushroom, so people with mushroom allergies should avoid it.
  • Ginger is mild in food amounts, but concentrated extracts can add to the effect of blood thinners.
  • Pregnancy and nursing: the page says nothing about them, and babchi is the main reason to ask a doctor first.

Because no amounts are disclosed, we cannot say how strong any of this would be in a single gummy. If you take prescription medication, have liver disease, or have a chronic condition, talk to a doctor or pharmacist before starting. None of this is medical advice.

Is Renew31 legit, and who is it for?

We found no independent coverage or complaints specific to Renew31, and the product appears to be a real gummy with named ingredients. The trouble is the pitch around it. There is no dose, a plant-retinol claim that the research does not support, a safety assurance stronger than the evidence, savings figures that do not add up, a competitor product’s name in a heading, and no named company. None of that proves a scam, but it describes a page written to sell first and explain second.

Our working definition of legit is a real company, a product that matches its label claims, and refunds that work. We cannot confirm the first, cannot test the second without doses, and have not seen the terms that govern the third.

A sensible fit if you

  • Want a probiotic-and-prebiotic gummy mainly for digestion and will check the bottle for amounts
  • Have asked the seller what the babchi is and how much is in each gummy
  • Will get the refund terms in writing before paying

Skip it if you

  • Have liver disease, take liver-processed medication, or are pregnant or nursing
  • Are buying it because you expect plant retinol or collagen effects from a gummy
  • Want published doses, an honest price comparison, and a named company

Common questions

Does Renew31 really improve skin?

Its probiotic has real research, but mostly on digestion. We are not aware of strong human evidence for the skin claims, and the page shows no dose. See the ingredients.

Is babchi the same as bakuchiol?

No. Bakuchiol is one compound from the seeds; the retinol comparisons used purified bakuchiol on skin. See the babchi section.

Is Renew31 safe?

The page says yes, but babchi seed products have documented liver and skin-sensitivity reports and the amount in a gummy is not disclosed. Ask your doctor and the seller first.

Are the savings on the page real?

Per-bottle prices are consistent, but two of the three “you save” figures do not match. See the price check.

Is the guarantee unconditional?

It is called unconditional but needs 30 days of use. See the guarantee.

What are the free bonuses?

Six digital guides with orders of 3 or 6 bottles, mostly not about skin. See the bonuses.

Who makes Renew31?

The bottle says Nature’s Nutriwave, but no company is named on the page. See who is behind it.

Is Renew31 FDA approved?

No. The FDA does not approve dietary supplements before sale.

Final verdict

Renew31 is a plausible gut-health gummy wearing a skin-care story. The probiotic and prebiotic are real ingredients with real research on digestion, and that is where the label is most honest. The skin claims lean on plant retinol that is not the plant retinol studied, on ingredients with no skin evidence we know of, and on a page with no doses, wrong savings math, another product’s name, and an assurance of safety that the babchi record does not support. If you are curious, ask the seller what the babchi is and how much each gummy holds, check the bottle for amounts, get the refund terms in writing, and keep your doctor in the loop if you have any liver or medication concerns.
