Thorne Liver Cleanse Review

Thorne Liver Cleanse is a capsule supplement built around a blend of clinically studied botanicals, including berberine and milk thistle alongside other traditional herbs. The product is positioned to promote the liver's natural detoxification function and to optimize the metabolism and excretion of substances the liver processes. The page explains that for proper digestion and detoxification, adequate liver function is essential, and that the botanicals in this formula have demonstrated their ability to support the liver's detoxification pathways and bile flow for digesting fats. Key ingredients listed are Chicory Extract (100mg), Burdock Extract (100mg), Berberine HCl from Indian Barberry extract (root) (125mg), and Milk Thistle Extract from Silybum marianum (125mg). The serving size is one capsule, with 60 servings per container. Other ingredients are Silicon Dioxide, Calcium Laurate, and a Hypromellose (derived from cellulose) capsule. The listed benefits are promoting the liver's natural detoxification functions, enhancing the liver's production and flow of bile for fat digestion, and optimizing the metabolism and excretion of substances detoxified by the liver. The page suggests the product is for individuals engaged in a detoxification protocol, people seeking daily support for optimal liver function, those who want to enhance bile production to support fat digestion and absorption, and anyone who has had their gallbladder removed. The features section highlights burdock root and chicory root, which have a long history of traditional medicinal use, and two extensively studied botanicals, berberine and milk thistle. The suggested starting dose is one capsule in the evening. If additional liver support is desired, the page says supplementation can be gradually increased to one capsule three times daily. The page also notes that a comprehensive detoxification program includes an effective fiber formula, and points to Thorne's FiberMend as a companion for eliminating toxins through healthy bowel movements and preventing their reabsorption. Thorne states the product has been third-party tested and certified to verify that what is in the package matches the label and to confirm it contains no unsafe levels of contaminants such as heavy metals, pesticides, and microorganisms. The warnings section states that the product is contraindicated in individuals with a history of hypersensitivity to any of its ingredients. It should not be used if pregnant, nursing, or trying to conceive. The page reports no known adverse interactions or contraindications at publication date. It also warns that, as with all detoxification regimens, proper intestinal elimination is essential, and that a person should have at least one healthy bowel movement daily. Individuals who are constipated should not supplement with Liver Cleanse because the toxins released into the bile may be reabsorbed.

Milk thistle is at a full dose here, and its studies are the strongest support for liver health. A pooled analysis of 55 trials with 3545 people with liver injury found its active extract, silymarin, lowered two main liver enzymes, with less benefit in drug or alcohol related liver disease [1]. A review of 26 trials in fatty liver found lower liver enzymes and blood fats and less liver fat on biopsy [2], and another pooled analysis linked it to better liver scarring scores [3]. In people with cirrhosis, it raised four year survival compared with placebo [4]. Berberine gives mixed results. A pooled analysis of 10 trials found lower liver enzymes and blood fats [5], but the largest trial, using 1 gram a day for 6 months, found no drop in liver fat [6]. A second pooled analysis found no clear change in liver enzymes [7]. The trials that worked used 1500 milligrams a day, more than this product provides [8]. Chicory is present at only a trace amount compared with the studied 10 grams [9]. Burdock has only animal studies [10]. Animal and cell studies are never counted.

Thorne Liver Cleanse has about 2,644 ratings across the stores that sell it, and the feedback is mostly positive. Buyers tend to like the brand and report feeling better over time, though a few saw no change. This summary covers the capsules only; no other forms of the product are covered. **What buyers say it did for them:** Several describe more energy or a lighter feeling. One wrote, "I feel lighter and healthier just taking these." Another said, "Can tell that I'm not sluggish anymore." One reviewer pairing it with another supplement reported a drop in LDL: "reduced my LDL levels by almost a 100 points." Timing varies. One buyer said they began to feel a difference "after about eight weeks," while another had "just started" and expected results in time. The store summaries add that some buyers noticed less bloating, better digestion, and deeper sleep, and that one used it for a family member's fatty liver. Several buyers are still waiting on bloodwork before judging results. Some were also changing their diet, which makes it hard to credit the capsules alone. **What buyers complain about:** Complaints are rare. The clearest is from a two-star reviewer: "saw no changes overall- mood, health, skin or energy." The store summaries say the few lower ratings come without written explanations, and that no written reviews mention side effects. **Taste, smell, pill size, form:** Little is said. One buyer called it "EASY TO TAKE," and the store summaries say no reviewer raised taste, aftertaste, or pill size as a problem. **Value for money:** Price is not discussed in any of the reviews or store summaries. One buyer said they had "ordered several bottles," and another plans to order more, which suggests repeat purchases. That is not a statement about cost. **Who it seems to suit and who it did not:** It seems to suit people who come to it on a doctor's, nurse practitioner's, or naturopath's recommendation and who want ongoing liver support. One reviewer said, "My ARNP advised me to continue taking this supplement." Another said, "I am so glad my doctor recommended this product." It also suits people who already trust the Thorne brand, and the store summaries mention some who use it seasonally as an occasional cleanse. One reviewer who had taken a different liver product for decades found this one simpler and quite effective. It did not suit the buyer who finished a full bottle and felt no difference, so people expecting quick, noticeable changes may be disappointed. The written feedback is a small sample compared with the total number of ratings, so treat it as an indication rather than a full picture.

Biohacker Summary

Members Only8 of 10 recommend it
8 of 10 biohackers on our panel recommend it

Milk thistle, the main ingredient, drew comments from six of the ten panelists, and most of them recommend it. Three recommend it for liver and detox support, including taking it before and after drinking, and one suggests a form standardized to 70 to 140 mg of silymarin taken 30 to 60 minutes before hot-cold contrast therapy. One panelist noted the research behind its liver benefits without taking a side, one mentioned it for allergy symptoms, and one tried it for liver health but stopped because it did nothing for him. Berberine is a smaller ingredient in this product, and panelists mostly take it for blood sugar, with one caution that taking it on an empty stomach caused headaches and low blood sugar.

Body systems: Digestive system, Liver, Metabolic system

Combine with: For liver support, milk thistle and dandelion pair well with N-acetylcysteine (NAC) or glutathione to support detoxification, alpha-lipoic acid for antioxidant support, and choline or phosphatidylcholine for fat metabolism in the liver. Artichoke leaf extract or TUDCA can add bile flow support. If the actual goal is blood sugar balance, consider adding berberine, chromium picolinate, magnesium, or cinnamon extract, since a healthy liver contributes to glucose regulation. Anyone taking meds should consult a healthcare provider first, as milk thistle and berberine may enhance glucose-lowering effects and cause hypoglycemia. Dandelion may also have a mild a med effect and may interact with certain medications, so professional guidance is advised.

Possible side effects: Berberine caused mild stomach and digestive side effects in studies. No side effects were seen with milk thistle in the cirrhosis trial.
