Liv Pure review: what the research says about a formula with no published doses

Liv Pure is sold as a liver support capsule for weight management. It names ten ingredients but hides every amount inside two proprietary blends. We looked at what the human research on each ingredient found, and at what that means when the doses are unknown.

What Liv Pure is

Liv Pure is a capsule supplement sold through ClickBank, which acts as the retailer. The sales pages and terms name only the brand, Liv Pure, and do not identify a parent company. Each bottle holds 60 capsules and is sold as a 30-day supply. The pages never state the daily serving outright; the math implies two capsules a day. Liv Pure is sold in 2, 3 and 6-bottle packages as a one-time purchase.

The link on this page opens a video presentation. The brand's main website shows the same packages in text form and lists the ingredients. Its pitch is that the liver is "the fat-burning furnace" for the whole body, that everyday toxins slow it down, and that supporting liver function switches the body into fat-burning mode. The page also says Liv Pure is suitable for "women and men from 18 to 80." We read it with men over 50 in mind.

The formula next to the research

The brand's website splits the formula into two named blends, each with five ingredients. It gives no milligram amounts for either blend or for any ingredient, and we found no Supplement Facts panel on either sales page. That leaves the right-hand column of our usual table empty for every row. Below is what the human research on each ingredient used, so you can see what Liv Pure would need to contain to match it.

We checked the formula against every product we have reviewed. None shares this ingredient list, so Liv Pure is not a relabel of a product already on our site.

Green tea: the best-known ingredient, with modest results

A Cochrane review looked at randomized trials of green tea preparations lasting at least 12 weeks in overweight or obese adults. In six trials run outside Japan (532 people), the average weight difference against control was 0.04 kg, which is effectively zero. Trials run in Japan showed differences from 0.2 to 3.5 kg but were too different from each other to pool. The authors concluded the effect is small and not likely to be clinically important ^[1]. An earlier meta-analysis of 11 studies found an average of about 1.3 kg in favor of catechins, with smaller effects in people with high habitual caffeine intake ^[2]. If you already drink several cups of coffee a day, that second point matters.

Berberine: a real signal, but small and inconsistent

Berberine is a plant compound from goldenseal, barberry and related plants. A 2026 meta-analysis of 23 randomized trials in adults found an average weight difference of 0.88 kg compared with control groups, along with smaller BMI and waist measurements. The authors also flagged weak reporting of purity and dose, and a lack of blinding in many trials ^[3]. An earlier dose-response meta-analysis of 10 studies found changes in BMI and waist size but no significant change in body weight ^[4]. The signal is real but modest, and berberine is also the ingredient most likely to interact with medications (see Safety).

Resveratrol and chlorogenic acid: small averages from short trials

Resveratrol is a polyphenol found in grape skins. A meta-analysis of 36 randomized trials found small reductions in weight, BMI, waist size and fat mass ^[5]. A second review of 28 trials put the average weight difference at about half a kilogram and found no significant effect on fat mass. Effects were clearer at doses under 500 mg a day, in trials of three months or more, and in people with obesity ^[6].

Chlorogenic acid is the main polyphenol in coffee beans. In a 12-week trial of 150 overweight Japanese adults, coffee providing 369 mg of chlorogenic acids a day reduced belly fat area and waist size more than a low-chlorogenic coffee ^[8]. That trial was funded and run by employees of the company that makes the coffee. A meta-analysis of green coffee extract at 500 mg a day pooled just three trials with 103 people ^[7]. The direction is favorable, but the evidence base is thin.

Betaine: two reviews, two answers

Betaine is a compound found in beets and whole grains. A 2019 meta-analysis of six trials (195 people) found less body fat but no change in body weight ^[12]. A larger 2022 meta-analysis concluded that betaine did not improve body weight, BMI, fat mass or body fat percentage, with similar results above and below 4 grams a day and above and below age 40 ^[11]. A capsule blend that shares space with nine other ingredients is unlikely to hold amounts in the gram range.

Silymarin and glutathione: liver ingredients without weight data

Silymarin, from milk thistle seeds, is the classic "liver" botanical. Its 2025 Cochrane review covered 17 trials with 2,069 adults diagnosed with fatty liver disease. It found that silymarin alone may lower some liver enzymes compared with placebo, with very low certainty of evidence, and that the overall benefits remain unclear ^[9]. The trials enrolled people with a diagnosed condition and did not measure weight loss in healthy adults, so they say nothing direct about Liv Pure's weight-management pitch.

For glutathione, a six-month trial in 54 healthy adults found that 250 or 1,000 mg a day of oral glutathione raised glutathione levels in blood ^[10]. That is a useful finding about absorption. The trial did not measure body weight or fat.

Molybdenum, genistein and choline

Molybdenum is a trace mineral, genistein is a soy isoflavone and choline is a nutrient involved in fat transport in the liver. Our PubMed searches found no human trial testing any of them for weight management in adults. Their presence fits the "liver" theme of the formula, but we found no outcome data to report.

What the marketing claims and what we could verify

The sales copy says a 2023 research team found "one common factor" in all overweight people, compromised liver function, and that with optimal liver function your liver cells "can be up to 14 times more efficient at burning fat." We could not trace either claim to a published study. The brand's website points to three PubMed records under the claim. All three are general reviews of "metabolic flexibility," the body's ability to switch between fuels. The abstract we checked focuses on skeletal muscle and fat tissue and does not mention a 14-fold figure ^[13].

The page our link opens also shows a long list of 38 "scientific references." Many of those references study L-carnitine, chromium, holy basil (tulsi), L-theanine and a green tea phytosome product. None of those ingredients appear in the formula listed on the brand's website. Several references are animal studies, including one in cats. In other words, the reference list does not match the ingredient list. We treat that mismatch as a transparency problem in its own right.

The brand's pages also tie individual ingredients to repairing or reversing liver damage and to fighting disease. We do not repeat those claims. A dietary supplement is not intended to diagnose or treat any liver condition, and nothing we found supports using Liv Pure for one.

Price, packages and refund policy

Prices on the official site when we checked:

• 6 bottles (180 days): $49 each ($294 total), free shipping. About $1.63 a day.
• 3 bottles (90 days): $69 each ($207 total), plus shipping.
• 2 bottles (60 days): $79 each ($158 total), plus shipping. There is no single-bottle option.

The seller describes a 60-day refund policy, including for empty bottles, with the refund issued after the product is returned and shipping and handling deducted. Note the timing: the 6-bottle package lasts 180 days but the refund window closes after 60. Most of the trials above ran about three months, so a 90-day supply is the shortest trial that resembles the research, and even that runs past the refund window. Every package is a one-time payment, according to the brand.

Safety

Because the doses are unknown, we cannot judge how much of any ingredient you would take. These are the interactions the research documents for the named ingredients:

• Berberine. In healthy men, 300 mg three times a day for two weeks reduced the activity of three liver enzymes (CYP2D6, CYP2C9 and CYP3A4) that clear many common drugs. Blood levels of a probe drug rose by about 40% ^[14]. If you take any prescription medicine, this is the ingredient to raise with your doctor or pharmacist first.
• Green tea extract. A United States Pharmacopeia review linked concentrated green tea extracts to rare cases of liver injury, especially when taken on an empty stomach. Its recommended cautions are to take it with food, avoid it with a liver problem, and stop and see a clinician if you notice abdominal pain, dark urine or yellowing of the skin or eyes ^[15]. Green tea catechins have also lowered blood levels of several drugs in human studies, including atorvastatin, rosuvastatin, lisinopril and nadolol, and raised sildenafil levels ^[16].
• Silymarin. A systematic review found that most human studies showed no meaningful drug interactions at usual doses ^[17].

Talk to your doctor before starting Liv Pure if you take blood pressure, cholesterol, diabetes or heart medication, blood thinners or any other prescription, or if you have a liver condition. Results vary from person to person, and new or worsening symptoms deserve medical care.

What we liked and what gave us pause

Frequently asked questions

How much of each ingredient is in Liv Pure?

We do not know. The brand lists the ten ingredients inside two proprietary blends and publishes no amounts. If you want the label before buying, ask customer support for the full Supplement Facts panel.

How long before I notice anything?

Results vary. The trials behind these ingredients mostly ran 12 weeks or longer and found small average changes, so judging any supplement in this category after a couple of weeks is too early. Diet, activity and sleep will matter more than any capsule.

Can Liv Pure help with a liver condition?

No supplement should be used for that. If you have abnormal liver tests or a diagnosed liver condition, follow your doctor's plan and ask before adding anything, especially products with green tea extract.

Is it a subscription?

No. According to the brand, every package is a one-time payment.

How we reviewed Liv Pure

We read the sales page our link opens, the brand's main website, its reference list and its terms. We looked for a Supplement Facts label and found none published. We then searched PubMed for human trials and systematic reviews of each named ingredient on body weight, body fat and safety. We did not test the product on people, and nobody at Stark Verve is a medical professional. Read our editorial policy to learn how we choose and update reviews. This is a review page, and Stark Verve earns a commission if you buy through our links; that never changes what we write about the evidence.
