QUICK ANSWER  Biogenique Milk Thistle provides 120 mg of a 30:1 Silybum marianum fruit extract per capsule, equivalent to 3,600 mg of dried fruit and standardized to 80% silymarin. That is 96 mg of silymarin per capsule. The licensed adult dose - one capsule three times daily - supplies 288 mg of silymarin and a 10,800 mg dried-fruit equivalent per day. NPN 80072265 is licensed to help support liver function. It is not licensed to cleanse toxins, reverse liver damage, treat fatty liver disease or hepatitis, or replace medical care.

What is milk thistle?

Milk thistle (Silybum marianum) is a flowering plant in the daisy family. Its fruit and seeds have a long history of use in herbal medicine, especially for liver-related purposes. Modern products can contain ground seed, non-standardized extracts, standardized extracts, liquid preparations or combinations with other ingredients. Those formats are not interchangeable. The exact extract, standardization, dose and licensed claim matter more than the plant name alone.

The best-known component is silymarin, which is not one single molecule but a mixture of flavonolignans, including silybin. Laboratory research has examined antioxidant, inflammatory and cell-signalling mechanisms. Mechanistic findings can explain why an ingredient is studied, but they do not prove that an oral supplement detoxifies the body or treats a liver disease in people. The useful consumer question is narrower: what does this formula contain, what is it licensed to claim in Canada, and how closely does human research match it?

What exactly is in the Biogenique formula?

• Medicinal ingredient: Milk thistle (Silybum marianum) fruit extract, 120 mg per capsule.

• Extract ratio: 30:1, equivalent to 3,600 mg of dried milk thistle fruit per capsule.

• Standardization: 80% silymarin, equal to 96 mg of silymarin per capsule by label math.

• Licensed adult dose: one capsule three times daily.

• Daily total: 360 mg of extract, 288 mg of silymarin and a 10,800 mg dried-fruit equivalent.

• Bottle size: 90 capsules, equal to 30 days at the licensed dose; NPN 80072265.

• Non-medicinal ingredient listed on the reviewed label: hydroxypropyl methylcellulose.

The product label uses a quantity crude equivalent (QCE). That figure describes the amount of starting dried fruit represented by the extract; it is not the physical weight of powder inside the capsule. It should therefore be written as '120 mg of a 30:1 extract, equivalent to 3,600 mg of dried fruit' - not '3,600 mg of extract.'

How can 120 mg equal 3,600 mg - and where does 96 mg come from?

The three numbers describe different properties. The capsule contains 120 mg of extract. A 30:1 ratio means that 30 parts of dried fruit are represented by one part of extract, so 120 mg x 30 equals a 3,600 mg dried-fruit equivalent. The extract is also standardized to 80% silymarin, so 120 mg x 0.80 equals 96 mg of silymarin. At three capsules daily, those totals become 360 mg of extract, 10,800 mg of dried-fruit equivalent and 288 mg of silymarin.

This math does not prove that the capsule is '30 times stronger' in a clinical sense, nor does it make 10.8 grams a separate swallowed dose. Extract ratios describe manufacturing concentration; standardization describes a measured constituent target. Neither number alone proves absorption, speed of action, superiority to another product or a health outcome.

Three evidence layers that should not be blended

What does 'supports liver function' actually mean?

Health Canada's licensed wording for NPN 80072265 is precise: 'Used in Herbal Medicine to help to support liver function.' This is a support claim for adults, not a disease-treatment claim. It does not mean that the product has been shown to cure hepatitis, reverse cirrhosis, remove liver fat, normalize abnormal blood tests or protect someone from the consequences of heavy alcohol use.

The current Health Canada milk thistle monograph permits liver-protectant and liver-function claims for qualifying preparations. For standardized extracts used for non-traditional claims, it lists 140 to 600 mg of silymarin per day and no more than 200 mg per single dose. The reviewed Biogenique label supplies 96 mg per capsule and 288 mg per licensed day, which fits within those monograph parameters. This alignment supports the licensed dose; it does not convert the product into a treatment for a diagnosed liver condition.

Does milk thistle 'detox' the liver?

'Detox' is one of the most overused words in supplement marketing. The liver already transforms, packages and helps eliminate many substances as part of normal physiology. A credible milk thistle claim should not imply that toxins are sitting in the liver waiting to be flushed out, that a short cleanse can undo alcohol exposure, or that taking a capsule compensates for medication misuse, poor diet, viral hepatitis or metabolic disease.

For this product, the evidence-based wording is 'helps support liver function.' That is still useful, but it is deliberately narrower than 'detoxifies the body.' If the word detox is used for consumer education, it should explain normal liver function rather than promise removal of unspecified toxins. The current product page goes further with natural-detox and antioxidant language; those statements are not the licensed claim shown on the reviewed label and should not be presented as Health Canada-approved outcomes.

What does the human evidence show?

The evidence is mixed because trials have used different silymarin extracts, doses, durations, formulations and patient populations. Some studies measure liver enzymes, others use imaging or biopsy findings, and many are too small or methodologically weak to settle clinical questions. A change in an enzyme is also not the same as fewer complications, better quality of life or longer life.

A 2025 Cochrane review assessed 17 randomized trials involving 2,069 adults with metabolic dysfunction-associated steatotic liver disease. The authors concluded that the benefits and harms of silymarin remain unclear. Possible changes in some liver enzymes were based on low- or very-low-certainty evidence, studies were heterogeneous, and none reported all-cause mortality or quality of life. That is a reason for careful language, not a reason to pretend there is no research at all.

In a 2012 multicentre randomized trial, 154 people with chronic hepatitis C received 420 mg or 700 mg of silymarin three times daily, or placebo, for 24 weeks. Even at those higher-than-customary doses, silymarin did not significantly improve ALT, viral levels or quality of life compared with placebo. A 2019 randomized trial in non-cirrhotic adults with steatohepatitis also found no significant benefit on its primary histological outcome. These trials involved diagnosed disease and specific research extracts; they do not test this retail capsule, but they directly refute disease-treatment promises.

PRACTICAL INTERPRETATION  The strongest defensible story is the licensed one: a standardized milk thistle extract used in Herbal Medicine to help support liver function. Do not turn mechanism studies, uncertain liver-enzyme findings or trials of other formulations into promises of detoxification, repair or disease treatment.

What does 80% silymarin tell you - and what does it not tell you?

Standardization improves formula clarity because it states the intended proportion of silymarin in the extract. Here, 80% allows the constituent math to be shown transparently: 96 mg per capsule and 288 mg per licensed day. That is more informative than listing only a raw-herb equivalent.

It still does not identify the full flavonolignan profile, guarantee how much reaches the bloodstream, or prove superior clinical results. Silymarin is a mixture, and commercial preparations can differ. Research on a proprietary silymarin formulation, a phospholipid complex or a different dose cannot be silently transferred to this formula. Claims such as 'three times better absorption' require direct comparative bioavailability evidence for the finished product; none appears in the reviewed NPN label or lot 240528 COA.

Claims the evidence does not establish for this product

• A liver cleanse, toxin flush or hangover cure.

• Prevention or treatment of hepatitis, fatty liver disease, steatohepatitis, cirrhosis or liver cancer.

• Reversal of liver damage or guaranteed normalization of ALT, AST or other laboratory tests.

• Protection that makes heavy alcohol use, medication misuse or toxin exposure safe.

• Clinically proven antioxidant protection or regeneration of liver cells from this finished product.

• Superior absorption, 'pharmaceutical-grade' status or faster results than another milk thistle product.

• Every-batch purity, potency and contaminant results based on one lot-specific COA.

How to take this exact product

The reviewed licensed label directs adults to take one capsule three times per day and to use it for at least three weeks to see beneficial effects. At that dose, a 90-capsule bottle provides 30 days. The label does not require taking it with food and does not prescribe exact morning, afternoon or evening times. Do not invent more specific instructions than the licence provides; follow the current label and choose a consistent schedule that supports adherence.

More is not automatically better. The product's dose is already calculated around its standardized extract. Taking extra capsules changes both the silymarin exposure and the crude-equivalent total, and it moves away from the licensed directions. Anyone using milk thistle because of abnormal liver tests, diagnosed liver disease or a complex medication regimen should involve the clinician managing that condition rather than self-adjusting the dose.

Safety, cautions and when to seek care

The licensed label says to consult a health-care practitioner before use if pregnant, to consult if symptoms persist or worsen, and to keep the product out of reach of children. Health Canada's current monograph also directs users to stop if hypersensitivity or allergy occurs. NCCIH reports that oral milk thistle is generally well tolerated, with digestive symptoms such as bloating, nausea and gas among the more common adverse effects.

Milk thistle can trigger allergic reactions, particularly in people sensitive to related plants such as ragweed, chrysanthemum, marigold or daisy. Reliable pregnancy and breastfeeding data are limited. Because herbal products can interact with medicines, ask a qualified health-care professional before use when taking prescription drugs, especially when the medication has a narrow safety margin or is being used for diabetes, cancer, transplantation or liver disease.

A supplement is not a safe way to investigate possible liver disease. Seek prompt medical assessment for jaundice, very dark urine, pale stools, persistent upper-right abdominal pain, vomiting, abdominal swelling, unusual bleeding, severe weakness or confusion. Do not delay testing or treatment while waiting to see whether a supplement helps.

What the lot-specific COA adds

The reviewed certificate of analysis is product- and lot-specific: Biogenique Milk Thistle, lot 240528, manufactured May 2024 with an April 2027 expiry. It reports an average capsule weight of 520.07 mg against a 517.00 mg +/- 7.5% specification and a five-minute disintegration time against a not-more-than-30-minute specification. Total plate count and yeast/mould were each reported below 10 CFU/g; E. coli, Salmonella, S. aureus and Pseudomonas aeruginosa were reported negative.

For the same lot, arsenic, cadmium, lead and mercury were each reported below 0.001 micrograms/kg body weight/day against the listed limits. Those results are meaningful quality evidence for lot 240528. They should not be rewritten as 'zero heavy metals,' because below a reporting threshold is not the same as absolute absence, and they should not be generalized to every lot without matching records.

The COA lists the formula but does not show a separate quantitative finished-product assay result for silymarin on the displayed certificate. It therefore supports the listed physical, microbial and heavy-metal checks, not a claim that finished-product potency or superior absorption was independently demonstrated. NPN authorization, label accuracy and batch testing answer different questions; a strong quality story keeps those layers separate.

Frequently asked questions

Is it 120 mg or 3,600 mg per capsule?

Both numbers are relevant, but they are not the same thing. Each capsule physically contains 120 mg of a 30:1 extract. That extract represents 3,600 mg of dried milk thistle fruit. The accurate wording is '120 mg extract, equivalent to 3,600 mg dried fruit.'

How much silymarin is in each capsule?

The extract is standardized to 80% silymarin. Eighty percent of 120 mg equals 96 mg of silymarin per capsule. At the licensed three-capsule daily dose, the calculated total is 288 mg.

Can milk thistle treat fatty liver disease?

This product is not licensed to treat fatty liver disease. A 2025 Cochrane review found the benefits and harms of silymarin in metabolic dysfunction-associated steatotic liver disease remain unclear, with low- to very-low-certainty evidence. Diagnosis and treatment require medical assessment and attention to the underlying metabolic risk factors.

Can I take it before or after drinking alcohol?

The licence does not support using milk thistle as a protective shield against alcohol or as a hangover treatment. A supplement does not cancel the dose-related risks of alcohol. The highest-value liver strategy is reducing harmful exposure, not trying to compensate for it afterward.

How long does it take to work?

The licensed label says to use the product for at least three weeks to see beneficial effects. That is not a promise that every person will feel a noticeable change at three weeks. Liver support may not produce a subjective sensation, and persistent symptoms or abnormal tests need clinical follow-up.

Should it be taken with food?

The reviewed label does not require food. Follow the current package directions. If the capsules cause digestive discomfort or if a clinician has given product-specific advice, use that guidance rather than relying on a generic internet rule.

The bottom line

Biogenique Milk Thistle has a clear, defensible formula story: 120 mg of a 30:1 fruit extract per capsule, equivalent to 3,600 mg dried fruit and standardized to 80% silymarin. One capsule three times daily supplies 288 mg of silymarin and a 10,800 mg dried-fruit equivalent. NPN 80072265 licenses the product for adults to help support liver function, with at least three weeks of use indicated before beneficial effects may be seen.

The boundary is just as important as the benefit. Current human evidence does not justify describing milk thistle as a liver-disease treatment, alcohol antidote or guaranteed detox. The 2025 Cochrane review found clinical uncertainty, and large disease-specific trials have not shown the outcomes that marketing often implies. Keep the blog precise: explain the extract math, use the licensed wording, retain the cautions and tie quality statements to the matching lot-specific COA.
