What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 3 of its 7 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (200 mg) without saying how much of each component you get.

This product contains 7 ingredients, including a proprietary blend. The active components are Vitamin B1, taurine, acerola cherry, kudzu root extract, royal jelly, milk thistle extract, and Hovenia dulcis extract.

Taurine is an amino acid your body makes naturally and uses for heart and muscle function. Acerola cherry is a natural source of vitamin C.

Kudzu root has been used in traditional medicine. Royal jelly is a nutrient-rich secretion from honeybees.

Milk thistle extract, particularly its active compound silymarin, has a long history of use for liver health. The inactive ingredients are gelatin, dicalcium phosphate, silica, and magnesium stearate.

Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Support healthy liver function.
  • We looked for evidence on: Alcohol-related liver disease, Cirrhosis, Hepatitis, Hepatitis B, Hepatitis C, Hypoxic liver injury — and 4 related terms.
  • The strongest evidence on file: Taurine is rated "Possibly Effective" for Hepatitis (Natural Medicines).
  • Also on file: Milk Thistle is rated "Insufficient Reliable Evidence To Rate" for Alcohol-related liver disease, Chemotherapy-induced hepatotoxicity, Metabolic dysfunction-associated steatotic liver disease (MASLD), Hepatitis C, and more.

The evidence for this product's components is mixed. Taurine is possibly effective for hepatitis and congestive heart failure, and possibly ineffective for obesity.

Acerola cherry is possibly effective for vitamin C deficiency; evidence is insufficient to rate it for the common cold or diarrhea. Kudzu is possibly effective for alcohol use disorder and possibly ineffective for hay fever, though evidence is insufficient for angina and back pain.

Royal jelly is possibly effective for menopausal symptoms but possibly ineffective for hay fever, physical performance, and diabetes. Milk thistle extract is possibly effective for diabetes but evidence is insufficient for acne, alcohol-related liver disease, hay fever, gambling disorder, and Amanita mushroom poisoning.

We hold no effectiveness data for Vitamin B1 or Hovenia dulcis extract in this database.

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 5 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most ingredients in this product are generally well tolerated in the short term. Taurine is well tolerated orally for up to one year in typical doses and causes mainly mild gastrointestinal effects like constipation or diarrhea, though long-term safety is less certain.

A small number of sensitive people have reported hypersensitivity reactions to taurine. Acerola cherry is generally considered safe at food amounts; one case report describes a person with latex allergies who had a severe allergic reaction to acerola juice.

Kudzu is generally well tolerated short-term with occasional nausea, bloating, or dizziness, but long-term safety is unclear. Royal jelly is generally well tolerated but can trigger serious allergic reactions — including anaphylaxis — in people with a history of asthma or atopy (a tendency toward allergies).

Milk thistle is well tolerated; mild gastrointestinal effects like nausea, bloating, or diarrhea may occur but are rare, and allergic reactions including anaphylaxis have been reported in rare cases. For pregnancy and breastfeeding, taurine is rated likely safe.

Kudzu, royal jelly, and milk thistle all have insufficient safety data and should be avoided during pregnancy and breastfeeding.

Milk Thistle Extract17 drug types · 954 drugs

Antidiabetes Drugs

Taking milk thistle with antidiabetes drugs may increase the risk of hypoglycemia.
Clinical research shows that milk thistle extract, alone or along with tree turmeric extract, can lower blood glucose levels and glycated hemoglobin (HbA1c) in patients with type 2 diabetes, including those already taking antidiabetes drugs. Additionally, animal research shows that milk thistle extract increases the metformin maximum plasma concentration and area under the curve and decreases the renal clearance of metformin, due to inhibition of the multi-drug and toxin extrusion protein 1 (MATE1) renal tubular transport protein.

Likelihood Possible Evidence B
Cytochrome P450 2B6 (Cyp2B6) Substrates

Theoretically, milk thistle might inhibit CYP2B6.
An in vitro study shows that silybin, a constituent of milk thistle, binds to and noncompetitively inhibits CYP2B6. Additionally, silybin might downregulate the expression of CYP2B6 by decreasing mRNA and protein levels.

Likelihood Possible Evidence D
Glucuronidated Drugs

Theoretically, milk thistle might affect the clearance of drugs that undergo glucuronidation.
Laboratory research shows that milk thistle constituents inhibit uridine diphosphoglucuronosyl transferase (UGT), the major phase 2 enzyme that is responsible for glucuronidation. Theoretically, this could decrease the clearance and increase levels of glucuronidated drugs. Other laboratory research suggests that a milk thistle extract of silymarin might inhibit beta-glucuronidase, although the significance of this effect is unclear.

Likelihood Possible Evidence D
Ledipasvir

Theoretically, milk thistle might increase the levels and clinical effects of ledipasvir.
Animal research in rats shows that milk thistle increases the area under the curve (AUC) for ledipasvir and slows its elimination.

Likelihood Possible Evidence D
Morphine

Theoretically, concomitant use of milk thistle with morphine might affect serum levels of morphine and either increase or decrease its effects.
Animal research shows that milk thistle reduces serum levels of morphine by up to 66%. In contrast, laboratory research shows that milk thistle constituents inhibit uridine diphosphoglucuronosyl transferase (UGT), the major phase 2 enzyme that is responsible for glucuronidation. Theoretically, this could decrease the clearance and increase morphine levels. The effect of taking milk thistle on morphine metabolism in humans is not known.

Likelihood Possible Evidence D
Raloxifene (Evista)

Theoretically, milk thistle might decrease the clearance and increase levels of raloxifene.
Laboratory research suggests that the milk thistle constituents silibinin and silymarin inhibit the glucuronidation of raloxifene in the intestines.

Likelihood Possible Evidence D
Sirolimus (Rapamune)

Milk thistle might decrease the clearance of sirolimus.
Pharmacokinetic research shows that a milk thistle extract of silymarin decreases the apparent clearance of sirolimus in hepatically impaired renal transplant patients. It is unclear if this interaction occurs in patients without hepatic impairment.

Likelihood Possible Evidence B
Sofosbuvir (Solvaldi)

Theoretically, milk thistle might decrease the levels and clinical effects of sofosbuvir.
Animal research in rats shows that milk thistle reduces the metabolism of sofosbuvir, as well as the hepatic uptake of its active metabolite.

Likelihood Possible Evidence D
Tamoxifen (Nolvadex)

Theoretically, the milk thistle constituent silibinin might increase tamoxifen levels and interfere with its conversion to an active metabolite.
Animal research suggests that the milk thistle constituent silibinin might increase plasma levels of tamoxifen and alter its conversion to an active metabolite. The mechanism appears to involve inhibition of pre-systemic metabolism of tamoxifen by cytochrome P450 (CYP) 2C9 and CYP3A4, and inhibition of P-glycoprotein-mediated efflux of tamoxifen into the intestine for excretion. Whether this interaction occurs in humans is not known.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, milk thistle might increase the effects of warfarin.
In one case report, a man stabilized on warfarin experienced an increase in INR from 2.64 to 4.12 after taking a combination product containing milk thistle 200 mg daily, as well as dandelion, wild yam, niacinamide, and vitamin B12. Levels returned to normal after stopping the supplement. Although a direct correlation between milk thistle and the change in INR cannot be confirmed, some in vitro research suggests that milk thistle might inhibit cytochrome P450 2C9 (CYP2C9), an enzyme involved in the metabolism of various drugs, including warfarin.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

It is unclear if milk thistle inhibits CYP2C9; research is conflicting.
In vitro research suggests that milk thistle might inhibit CYP2C9. Additionally, 3 case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking milk thistle and cancer medications that are CYP2C9 substrates, including imatinib and capecitabine. However, contradictory clinical research shows that milk thistle extract does not inhibit CYP2C9 or significantly affect levels of the CYP2C9 substrate tolbutamide. Differences in results could be due to differences in dosages or formulations utilized.

Likelihood Unlikely Evidence B
Cytochrome P450 3A4 (Cyp3A4) Substrates

It is unclear if milk thistle inhibits CYP3A4; research is conflicting.
While laboratory research shows conflicting results, pharmacokinetic research shows that taking milk thistle extract 420-1350 mg daily does not significantly affect the metabolism of the CYP3A4 substrates irinotecan, midazolam, or indinavir. However, 8 case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking milk thistle and cancer medications that are CYP3A4 substrates, including gefitinib, sorafenib, doxorubicin, and vincristine.

Likelihood Unlikely Evidence D
Estrogens

Theoretically, milk thistle might interfere with estrogen therapy through competition for estrogen receptors.
Animal research suggests that a milk thistle extract of silymarin binds to estrogen receptor beta.

Likelihood Possible Evidence D
Hmg-Coa Reductase Inhibitors ("Statins")

Theoretically, milk thistle might interfere with statin therapy by decreasing the activity of organic anion transporting polypeptide 1B1 (OATB1B1) and inhibiting breast cancer resistance protein (BCRP).
Preliminary evidence suggests that a milk thistle extract of silymarin can decrease the activity of the OATP1B1, which transports HMG-CoA reductase inhibitors into the liver to their site of action, and animal research shows this increases the maximum plasma concentration of pitavastatin and pravastatin. The silibinin component also inhibits BCRP, which transports statins from the liver into the bile for excretion. However, in a preliminary study in healthy males, silymarin 140 mg three times daily had no effect on the pharmacokinetics of a single 10 mg dose of rosuvastatin.

Likelihood Unlikely Evidence D
Indinavir (Crixivan)

Theoretically, milk thistle may induce cytochrome P450 3A4 (CYP3A4) enzymes and increase the metabolism of indinavir; however, results are conflicting.
One pharmacokinetic study shows that taking milk thistle (Standardized Milk Thistle, General Nutrition Corp.) 175 mg three times daily in combination with multiple doses of indinavir 800 mg every 8 hours decreases the mean trough levels of indinavir by 25%. However, results from the same pharmacokinetic study show that milk thistle does not affect the overall exposure to indinavir. Furthermore, two other pharmacokinetic studies show that taking specific milk thistle extract (Legalon, Rottapharm Madaus; Thisilyn, Nature's Way) 160-450 mg every 8 hours in combination with multiple doses of indinavir 800 mg every 8 hours does not reduce levels of indinavir.

Likelihood Unlikely Evidence B
Organic Anion-Transporting Polypeptide Substrates (Oatp)

Milk thistle may inhibit one form of OATP, OATP-B1, which could reduce the bioavailability and clinical effects of OATP-B1 substrates.
In vitro research shows that milk thistle inhibits OATP-B1. Two case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking milk thistle and cancer medications that are OATP substrates, including sorafenib and methotrexate. OATPs are expressed in the small intestine and liver and are responsible for the uptake of drugs and other compounds into the body. Inhibition of OATP may reduce the bioavailability of oral drugs that are substrates of OATP.

Likelihood Possible Evidence D
P-Glycoprotein Substrates

Theoretically, milk thistle might increase the absorption of P-glycoprotein substrates. However, this effect does not seem to be clinically significant.
In vitro research shows that milk thistle can inhibit P-glycoprotein activity and 1 case report from the World Health Organization (WHO) adverse drug reaction database describes increased abdominal pain in a patient taking milk thistle and the cancer medication vincristine, a P-glycoprotein substrate, though this patient was also taking methotrexate. However, a small pharmacokinetic study in healthy volunteers shows that taking milk thistle (Enzymatic Therapy Inc.) 900 mg, standardized to 80% silymarin, in 3 divided doses daily for 14 days does not affect absorption of digoxin, a P-glycoprotein substrate.

Likelihood Unlikely Evidence B

Kudzu Root Extract7 drug types · 584 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, kudzu may increase the risk of bleeding if used with antiplatelet or anticoagulant drugs.
Kudzu isoflavones are reported to have antiplatelet activity.

Likelihood Possible Evidence D
Caffeine

Theoretically, taking kudzu with caffeine might increase levels of caffeine.
In healthy males injected with the kudzu constituent puerarin, caffeine clearance and metabolism is inhibited. This effect has been attributed to inhibition of cytochrome P450 1A2 (CYP1A2) enzyme, which is involved in caffeine metabolism. It is unclear if taking kudzu orally would have this same effect.

Likelihood Probable Evidence D
Estrogens

Theoretically, kudzu might alter the effects of estrogen therapy.
Some research suggests that kudzu has estrogenic effects. This may enhance or inhibit the effects of estrogen therapy.

Likelihood Possible Evidence B
Hepatotoxic Drugs

Theoretically, concomitant use might have additive hepatotoxic effects.
There is some concern that kudzu can adversely affect the liver.

Likelihood Possible Evidence D
Methotrexate (Trexall, Others)

Theoretically, taking kudzu with methotrexate might increase the risk of methotrexate toxicity.
Preclinical research suggests that kudzu extract greatly reduces the elimination and increases the toxicity of methotrexate. Kudzu might inhibit organic anion transporters (OATs) that are responsible for hepatobiliary and renal excretion of anions, similar to the interaction between methotrexate and non-steroidal anti-inflammatory drugs (NSAIDs).

Likelihood Possible Evidence D
Tamoxifen (Nolvadex)

Theoretically, kudzu might interfere with tamoxifen activity.
Some research suggests that kudzu may have estrogenic effects.

Likelihood Possible Evidence B
Antidiabetes Drugs

Theoretically, taking kudzu with antidiabetes drugs might increase the risk of hypoglycemia.
Kudzu might lower blood glucose levels and have additive effects in patients treated with antidiabetic agents. The dose of diabetes medications might need to be adjusted.

Likelihood Unlikely Evidence D

Royal Jelly2 drug types · 174 drugs

Antihypertensive Drugs

Theoretically, royal jelly might increase the risk of hypotension when taken with antihypertensive drugs.
Animal research suggests that royal jelly might lower blood pressure.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Royal jelly might increase the risk of bleeding when taken with warfarin.
In one case, an 87-year-old male who was previously stabilized on warfarin developed hematuria and was found to have an INR of 7.29 after taking a royal jelly supplement for one week.

Likelihood Possible Evidence D

Taurine2 drug types · 173 drugs

Antihypertensive Drugs

Theoretically, taurine might increase the risk of hypotension when taken with antihypertensive drugs.
Some clinical evidence suggests that taurine can reduce both systolic and diastolic blood pressure.

Likelihood Probable Evidence D
Lithium

Theoretically, taurine might reduce excretion and increase plasma levels of lithium.
Taurine is thought to have diuretic properties, which might reduce the excretion of lithium.

Likelihood Probable Evidence D

Acerola Cherry6 drug types · 128 drugs

Alkylating Agents

Theoretically, the antioxidant effects of acerola might reduce the effectiveness of alkylating agents.
Acerola contains vitamin C, an antioxidant. There is concern that antioxidants might reduce the activity of chemotherapy drugs that generate free radicals, such as alkylating agents. In contrast, other researchers theorize that antioxidants might make alkylating chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as vitamin C have on chemotherapy.

Likelihood Possible Evidence D
Antitumor Antibiotics

Theoretically, the antioxidant effects of acerola might reduce the effectiveness of antitumor antibiotics.
Acerola contains vitamin C, an antioxidant. There is concern that antioxidants might reduce the activity of chemotherapy drugs that generate free radicals, such as antitumor antibiotics. In contrast, other researchers theorize that antioxidants might make antitumor antibiotic chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effects, if any, antioxidants such as vitamin C have on antitumor antibiotic chemotherapy.

Likelihood Possible Evidence D
Aluminum

Theoretically, concomitant use of acerola with aluminum salts might increase the amount of aluminum absorbed.
Acerola contains vitamin C. It is thought that vitamin C chelates aluminum, keeping it in solution and available for absorption. In people with normal renal function, urinary excretion of aluminum likely increases, making aluminum retention and toxicity unlikely. However, patients with renal failure who take aluminum-containing compounds, such as phosphate binders, should avoid acerola in doses that provide more vitamin C than the recommended dietary allowances.

Likelihood Possible Evidence D
Aspirin

Theoretically, acerola might reduce the clearance of aspirin; however, its vitamin C content is likely too low to produce clinically significant effects.
Acerola contains vitamin C. It has been suggested that acidification of the urine by vitamin C can decrease the urinary excretion of salicylates, increasing plasma salicylate levels. However, short-term use of up to 6 grams daily of vitamin C does not seem to affect urinary pH or salicylate excretion. The vitamin C content of acerola is typically about 2000 mg per 100 grams. Thus, a clinically significant interaction between acerola and aspirin is unlikely.

Likelihood Unlikely Evidence B
Estrogens

Theoretically, concomitant use of acerola with estrogens might increase estrogenic effects.
Acerola contains vitamin C. Increases in plasma estrogen levels of up to 55% have occurred under some circumstances when vitamin C is taken concurrently with oral contraceptives or hormone replacement therapy, including topical products. It is suggested that vitamin C prevents oxidation of estrogen in the tissues, regenerates oxidized estrogen, and reduces sulfate conjugation of estrogen in the gut wall. When tissue levels of vitamin C are high, these processes are already maximized and supplemental vitamin C does not have any effect on estrogen levels. However, increases in plasma estrogen levels may occur when women who are deficient in vitamin C take supplements.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, acerola might reduce the effectiveness of warfarin; however, its vitamin C content is likely too low to produce clinically significant effects.
Acerola contains vitamin C. High doses of vitamin C may reduce the response to warfarin, possibly by causing diarrhea and reducing warfarin absorption. This occurred in two people who took up to 16 grams daily of vitamin C, and resulted in decreased prothrombin time. Lower doses of 5-10 grams daily of vitamin C can also reduce warfarin absorption, but this does not seem to be clinically significant. The vitamin C content of acerola is typically about 2000 mg per 100 grams. Thus, a clinically significant interaction between acerola and warfarin is unlikely.

Milk Thistle Complex Capsules by Esmond Natural: Common Questions

Does Milk Thistle Complex Capsules by Esmond Natural interact with any medications?
Yes. Based on its ingredients, Milk Thistle Complex Capsules has a known interaction with 1,300 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Milk Thistle Complex Capsules contains 7 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Does this product contain milk?
No. Despite the name "Milk Thistle," this plant has no connection to dairy milk. Milk thistle extract and the other botanical ingredients are plant-based.
Can I take this while pregnant or breastfeeding?
Taurine is rated likely safe in pregnancy. However, kudzu, royal jelly, and milk thistle all have insufficient safety data — the facts advise against use during pregnancy and breastfeeding. Talk to your doctor or pharmacist for personalized advice.
What side effects might I experience?
Most people tolerate this product well. The most common mild effects are gastrointestinal — nausea, bloating, diarrhea, or constipation. Rarely, people with allergies or asthma sensitivities may have allergic reactions to royal jelly or milk thistle.
Is this product safe for people with asthma or allergies?
People with a history of asthma or atopy (tendency toward allergies) should be cautious. Royal jelly in particular has been associated with serious allergic reactions — including anaphylaxis — in this population. Talk to your doctor before use if this applies to you.
Can I take this long-term?
Long-term safety is not well established for taurine and kudzu. Most ingredients show good short-term tolerance, but a pharmacist or doctor should guide long-term use, especially if you have liver or heart conditions.
Does this actually work for liver health?
Milk thistle extract is possibly effective for diabetes and has a traditional reputation for liver support, but evidence is insufficient to rate it for alcohol-related liver disease or other liver conditions. Quality and effectiveness vary, and a doctor should be involved if you're using it for a liver condition.
