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 0 of its 5 active ingredients.
  • “Proprietary Herbal Blend” is a proprietary blend — the label gives one combined amount (650 mg) without saying how much of each component you get.

LeanCare contains five active ingredients: fenugreek seed, a proprietary herbal blend (whose specific components aren't disclosed on the label), chebulic myrobalan, guggul resin, and gymnema leaf. The product also lists vegetable cellulose as an inactive ingredient (the capsule material).

Fenugreek is traditionally used for blood sugar support and sexual function. Guggul is used for cholesterol and weight management.

Gymnema is used for blood sugar support, and garcinia (hydroxycitric acid) — which is part of the proprietary blend — is marketed for weight management. The specific role of chebulic myrobalan in this formula isn't specified in our data.

Does it work?

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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: support healthy lipid metabolism and weight management.
  • We looked for evidence on: Hypercholesterolemia, Hyperlipidemia, Obesity, Metabolic syndrome, dyslipidemia, overweight.
  • The closest evidence on file: Guggul is rated "Possibly Ineffective" for Obesity (Natural Medicines).
  • Also on file: Guggul is rated "Insufficient Reliable Evidence To Rate" for Hypercholesterolemia.
  • Also on file: Fenugreek is rated "Insufficient Reliable Evidence To Rate" for Hyperlipidemia, Obesity, Metabolic syndrome.

The evidence backing these ingredients is mixed. Fenugreek shows possibly effective evidence for sexual dysfunction, sexual arousal, irregular menstrual bleeding (dysmenorrhea), and diabetes support.

Guggul, however, is rated possibly ineffective for obesity, with insufficient evidence for acne, hemorrhoids, and high cholesterol. Gymnema is rated insufficient evidence for diabetes, obesity, prediabetes, and metabolic syndrome — we don't have solid proof it works for those uses in humans.

Garcinia likewise has insufficient evidence for athletic performance, fatty liver disease, high cholesterol, and obesity. The proprietary blend's effectiveness depends on what's actually in it; we can't verify that without ingredient disclosure.

The evidence, ingredient by ingredient Fenugreek Guggul Gymnema Garcinia

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 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Fenugreek is generally well tolerated in food amounts, though supplement doses may cause digestive side effects (abdominal pain, bloating, diarrhea, gas, nausea) and rarely severe allergic reactions. It's rated likely unsafe in pregnancy because it may affect the uterus; possibly safe while breastfeeding but should be discussed with your provider first.

Guggul is generally well tolerated but can cause digestive upset (bloating, diarrhea, nausea) and dose-dependent skin reactions (rash, itching, swelling); rare cases of rhabdomyolysis have been reported. It's rated likely unsafe in pregnancy and best avoided while breastfeeding.

Gymnema is well tolerated short-term but can lower blood sugar; rare cases of drug-induced hepatitis (liver inflammation) have been reported. Avoid in pregnancy and while breastfeeding due to insufficient safety data.

Garcinia is generally tolerated short-term, though common side effects include diarrhea, stomach discomfort, headache, and nausea; rare reports of liver injury, heart inflammation, and mania exist. Avoid in pregnancy and while breastfeeding.

Chebulic myrobalan safety data isn't on file.

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 4 of the 4 matched ingredients can interact with medications — Guggul, Fenugreek, Garcinia, Gymnema.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 1,274 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking LeanCare, double-check the following with your own pharmacist or doctor: serotonergic drugs like SSRIs (antidepressants), blood thinners and antiplatelet medications, diabetes drugs, blood pressure medications, beta-blockers, calcium-channel blockers, thyroid hormone therapy, birth control pills and estrogens, seizure medications, drugs metabolized by liver enzymes (CYP1A2, CYP2C9, CYP3A4), and any potentially liver-damaging drugs. This is not a complete list — the search tool on this page lets you check your exact medications.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

LeanCare may appeal to someone looking for traditional herbal weight and blood sugar support, but the evidence for effectiveness is limited or missing for most uses. If you take any medications — especially blood thinners, diabetes drugs, antidepressants, birth control, thyroid medication, or heart drugs — check with your own doctor or pharmacist before starting, because this product has a large number of documented interactions.

Pregnant people and those breastfeeding should avoid it. Talk it over with your healthcare provider to see if it's appropriate for your situation.

Each ingredient & the kinds of drugs it affects

For each ingredient in LeanCare with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Gymnema6 drug types · 851 drugs

Antidiabetes Drugs

Theoretically, taking gymnema with antidiabetes drugs might increase the risk of hypoglycemia.
Gymnema reduces blood glucose levels in some human and animal research. In human studies, it has been shown to enhance the blood glucose lowering effects of hypoglycemic drugs. However, other research in adults with prediabetes or metabolic syndrome suggests that gymnema does not reduce fasting levels of blood glucose. Until more is known, monitor blood glucose levels closely.

Likelihood Probable Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, gymnema might increase levels of drugs metabolized by CYP1A2.
Animal and in vitro research shows that gymnema can inhibit the CYP1A2 enzyme. In one animal study, oral administration of gymnema for 7 days increased the plasma concentrations of phenacetin, a CYP1A2 substrate, by about 1.4-fold and reduced the clearance of phenacetin by about 29%.

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

Theoretically, gymnema might increase or decrease levels of drugs metabolized by CYP2C9.
Animal research shows that gymnema can induce the CYP2C9 enzyme. In one animal study, gymnema caused a 2.4-fold increase in the clearance of tolbutamide, a CYP2C9 substrate, in rats. In vitro research also shows that gymnema can inhibit CYP2C9.

Likelihood Possible Evidence D
Phenacetin

Theoretically, taking gymnema with phenacetin might increase the levels of phenacetin.
Animal research shows that gymnema, administered orally for 7 days, decreases the clearance of phenacetin in a dose-dependent manner by about 21% to 29% and increases plasma levels about 1.3- to 1.4-fold when compared to control.

Likelihood Possible Evidence D
Tolbutamide (Orinase)

Theoretically, taking gymnema with tolbutamide might the decrease levels of tolbutamide.
Animal research shows that gymnema, administered orally for 7 days, increases the clearance of tolbutamide by 2.4-fold when compared to control.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, gymnema might increase levels of drugs metabolized by CYP3A4.
One in vitro study using rat liver microsomes shows that gymnema can modestly inhibit the CYP3A4 enzyme. However, other in vitro research using human liver microsomes shows that gymnema does not affect CYP3A4 activity. Animal research also shows that gymnema does not alter the function of CYP3A4. In one study in rats, oral administration of gymnema for 7 days did not alter the clearance of amlodipine, a CYP3A4 substrate.

Likelihood Unlikely Evidence D
Gymnema full monograph & interactions

Guggul9 drug types · 757 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, guggul might increase the risk of bleeding when taken with anticoagulant/antiplatelet drugs.
In vitro research and preliminary clinical studies suggest that guggul might have antiplatelet and anticoagulant effects.

Likelihood Possible Evidence B
Contraceptive Drugs

Theoretically, guggul might increase the risk of adverse effects when taken with contraceptive drugs.
In vitro research shows that guggul has estrogen-alpha receptor agonist activity.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, guggul might reduce the effects of CYP3A4 substrates.
In vitro research shows that guggul constituents known as guggulsterones can induce CYP3A4.

Likelihood Probable Evidence D
Diltiazem (Cardizem, Others)

Guggul might reduce the effects of diltiazem.
A small pharmacokinetic study shows that concomitant use of guggul with diltiazem reduces the bioavailability of diltiazem.

Likelihood Probable Evidence B
Estrogens

Theoretically, guggul might increase the risk of adverse effects when taken with estrogens.
In vitro research shows that guggul constituents known as guggulsterones have estrogen-alpha receptor agonist activity.

Likelihood Possible Evidence D
Propranolol (Inderal)

Guggul might reduce the effects of propranolol.
A small pharmacokinetic study shows that concomitant use of guggul with propranolol reduces the bioavailability of propranolol.

Likelihood Probable Evidence B
Rosuvastatin (Crestor)

Theoretically, guggul might increase the effects and adverse effects of rosuvastatin.
Animal research shows that guggul increases the bioavailability and hypolipidemic effects of rosuvastatin. The mechanism of this interaction is unclear.

Likelihood Possible Evidence D
Tamoxifen (Nolvadex)

Theoretically, guggul might interfere with tamoxifen therapy.
In vitro research shows that guggul has estrogen-alpha receptor agonist activity.

Likelihood Possible Evidence D
Thyroid Hormone

Theoretically, guggul might increase the risk for adverse effects when taken with thyroid hormone therapy.
Animal research suggests that guggul has thyroid-stimulating effects.

Likelihood Probable Evidence B
Guggul full monograph & interactions

Garcinia4 drug types · 704 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, hydroxycitric acid (HCA), the main active ingredient in garcinia, might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
HCA inhibits platelet aggregation in vitro. The inhibitory effect seems to be greater in platelets extracted from diabetic subjects than non-diabetic subjects.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, hydroxycitric acid (HCA), the main active ingredient in garcinia, might have additive effects with antidiabetes drugs and increase the risk of hypoglycemia.
HCA reduces fasting and postprandial blood glucose levels in animal models, theoretically by delaying glucose absorption. This effect has not been reported in humans.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, concomitant use with other potentially hepatotoxic drugs might increase the risk of developing liver damage.
There have been reports of acute hepatitis with elevated liver enzymes associated with garcinia, when taken alone or in combination with other ingredients. Case reports collected from the Drug Induced Liver Injury Network suggest this risk may be greater in people who carry the HLA B*35:01 allele.

Likelihood Possible Evidence D
Serotonergic Drugs

Theoretically, combining garcinia with other serotonergic drugs might increase the risk of serotonergic side effects, including serotonin syndrome.
In one report, a patient experienced serotonin syndrome after taking garcinia extract (60% hydroxycitric acid) 1000 mg daily in combination with escitalopram 20 mg, which had been taken for a year. The patient was switched to sertraline 50 mg daily and again experienced serotonin syndrome.

Likelihood Possible Evidence D
Garcinia full monograph & interactions

Fenugreek9 drug types · 389 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, fenugreek might have additive effects when used with anticoagulant or antiplatelet drugs.
Some of the constituents in fenugreek have antiplatelet effects in animal and in vitro research. However, common fenugreek products might not contain sufficient concentrations of these constituents for clinical effects. A clinical study in patients with coronary artery disease or diabetes shows that taking fenugreek seed powder 2.5 grams twice daily for 3 months does not affect platelet aggregation, fibrinolytic activity, or fibrinogen levels .

Likelihood Unlikely Evidence B
Antidiabetes Drugs

Theoretically, fenugreek seed might have additive hypoglycemic effects when used with antidiabetes drugs.
Clinical research shows that fenugreek seed can reduce fasting blood glucose and 2-hour postprandial glucose levels in adults with type 2 diabetes.

Likelihood Probable Evidence B
Clopidogrel (Plavix)

Theoretically, fenugreek seed might alter the clinical effects of clopidogrel by inhibiting its conversion to the active form.
Animal research shows that fenugreek seed 200 mg/kg daily for 14 days increases the maximum serum concentration of clopidogrel by 21%. It is unclear how this affects the pharmacokinetics of the active metabolite of clopidogrel; however, this study found that concomitant use of fenugreek seed and clopidogrel prolonged bleeding time by an additional 11%.

Likelihood Possible Evidence D
Metoprolol (Toprol)

Theoretically, fenugreek seed might have additive hypotensive effects when used with metoprolol.
Animal research shows that fenugreek seed 300 mg/kg daily for 2 weeks decreases systolic and diastolic blood pressure by 9% and 11%, respectively, when administered alone, and by 15% and 22%, respectively, when given with metoprolol 10 mg/kg.

Likelihood Probable Evidence B
Phenytoin (Dilantin)

Theoretically, fenugreek might decrease plasma levels of phenytoin.
Animal research shows that taking fenugreek seeds for 1 week decreases maximum concentrations and the area under the curve of a single dose of phenytoin by 44% and 72%, respectively. This seems to be related to increased clearance. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Sildenafil (Viagra)

Theoretically, concurrent use of sildenafil and fenugreek might reduce levels and therapeutic effects of sildenafil.
Animal research shows that taking fenugreek seeds for 1 week reduces maximum concentrations and the area under the curve of a single dose of sildenafil by 27% and 48%, respectively. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Theophylline

Theoretically, fenugreek may reduce the levels and clinical effects of theophylline.
Animal research shows that fenugreek 50 grams daily for 7 days reduces the maximum serum concentration (Cmax) of theophylline by 28% and the area under the plasma drug concentration-time curve (AUC) by 22%.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, fenugreek might have additive effects with warfarin and increase the international normalized ratio (INR).
Some fenugreek constituents have antiplatelet effects, although these might not be present in concentrations that are clinically significant. In one case report, a patient taking warfarin experienced an increased INR when starting to take fenugreek in combination with boldo.

Likelihood Possible Evidence D
Antihypertensive Drugs

Fenugreek may also have an additive effect on blood pressure-lowering medications. Studies on animals have shown that fenugreek seed can decrease both systolic and diastolic blood pressure by up to 22% when combined with metoprolol. Therefore, it is essential to monitor your blood pressure regularly if you are taking fenugreek and metoprolol together or any other antihypertensive drugs.

LeanCare by Himalaya: Common Questions

Does LeanCare by Himalaya interact with any medications?
Yes. Based on its ingredients, LeanCare has a known interaction with 1,273 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
LeanCare contains 5 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.
Can I take this if I'm pregnant?
No — fenugreek and guggul are rated likely unsafe in pregnancy because they may affect the uterus. Garcinia and gymnema don't have enough safety data and are best avoided. Talk with your doctor or pharmacist before considering any supplement during pregnancy.
Will this lower my blood sugar?
Yes, theoretically. Fenugreek and gymnema both reduce blood glucose in research, and garcinia may do so as well. If you take diabetes medication, combined use could lower your blood sugar too much. Check with your pharmacist before starting.
Does this help with weight loss?
Garcinia (in the proprietary blend) and guggul are marketed for weight management, but the evidence is either insufficient or shows they may not be effective. The data we hold doesn't confirm they work for obesity in humans.
What are the most common side effects?
Fenugreek commonly causes digestive upset — bloating, gas, diarrhea, and nausea. Guggul can cause similar digestive symptoms plus dose-dependent skin reactions. Garcinia may cause diarrhea, stomach discomfort, headache, and nausea.
I'm taking warfarin. Is this safe?
No — fenugreek and garcinia both raise bleeding risk when combined with warfarin and other blood thinners. Do not start this product without talking to your doctor or pharmacist first.
Can I take this with my antidepressant?
Check first. Garcinia in this formula may increase serotonin effects and cause serotonin syndrome when combined with SSRIs and other serotonergic drugs. Talk with your pharmacist about your specific medication before using LeanCare.
