HelloPharmacist Scorecard of Fenugreek by plnt

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: organic fenugreek seed. Fenugreek is a legume seed traditionally used in cooking and herbal medicine, and it does contain compounds that may affect blood sugar, blood clotting, and how your body processes certain medications.

The capsule itself is made of vegetable cellulose, an inactive ingredient.

Does it work?

Moderate evidence
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: Supports blood sugar levels already in normal range.
  • We looked for evidence on: Diabetes, Impaired glucose tolerance (prediabetes), Metabolic syndrome, Glycemic control, Insulin sensitivity.
  • The strongest evidence on file: Fenugreek is rated "Possibly Effective" for Diabetes (Natural Medicines).
  • Also on file: Fenugreek is rated "Insufficient Reliable Evidence To Rate" for Impaired glucose tolerance (prediabetes), Metabolic syndrome.

The evidence we hold shows fenugreek is possibly effective for sexual dysfunction, dysmenorrhea (period pain), and type 2 diabetes. For sexual dysfunction, the data suggests benefit but isn't definitive.

For blood sugar control in diabetes, clinical research does show fenugreek can lower fasting glucose and post-meal glucose levels in people with type 2 diabetes. Keep in mind that 'possibly effective' means promising findings, not proof—talk with your doctor about whether it fits your situation.

The evidence, ingredient by ingredient Fenugreek

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Fenugreek is generally well tolerated when eaten as food, but supplement doses can cause side effects. The most common ones are digestive: abdominal pain, bloating, diarrhea, indigestion, gas, and nausea.

A small number of people have had low blood sugar (hypoglycemia). Rare but serious allergic reactions—including severe swelling, wheezing, and anaphylaxis—have been reported.

If you have a legume allergy, be cautious. Fenugreek may also cause an unusual body odor in you or a breastfed infant, which could be mistaken for maple syrup urine disease, though this doesn't appear to cause lasting harm.

Do not use fenugreek as a supplement during pregnancy—the safety data advises against it. For breastfeeding, there isn't enough data to know whether it's safe; the evidence suggests possible benefit for milk supply, but discuss it with your doctor or lactation consultant first.

Side effects, ingredient by ingredient Fenugreek

Meds to double-check

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?
  • 1 of the 1 matched ingredient can interact with medications — Fenugreek.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 389 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 fenugreek, double-check with your pharmacist or doctor if you take blood thinners or antiplatelet drugs (warfarin, clopidogrel, or others), diabetes medications, blood pressure drugs (especially metoprolol), theophylline for breathing problems, seizure medications like phenytoin, or erectile dysfunction drugs like sildenafil. Fenugreek may reduce how well some of these work or increase bleeding risk.

organic 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.

Fenugreek by plnt: Common Questions

Does Fenugreek by plnt interact with any medications?
Yes. Based on its ingredients, Fenugreek has a known interaction with 389 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Fenugreek contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
Will fenugreek help my blood sugar?
Clinical research shows fenugreek seed can lower fasting blood glucose and post-meal glucose levels in adults with type 2 diabetes, so the evidence we hold rates it possibly effective for that. But it's not a replacement for your diabetes medication—it works best as part of a full plan. Talk with your doctor before adding it.
Can I take fenugreek while pregnant?
No. The safety data advises against medicinal use of fenugreek during pregnancy because it may affect the uterus. If you're pregnant or planning to be, skip this supplement and talk with your doctor about what's safe.
Is fenugreek safe for breastfeeding?
The evidence we have rates it possibly safe for lactation and it's often used to boost milk supply, but the research is limited. There's one quirk: fenugreek can cause an unusual body odor in breastfed infants. Discuss it with your doctor or lactation consultant before starting—they can advise what's right for you and your baby.
What side effects might I get from fenugreek?
Most common are digestive issues: bloating, gas, diarrhea, stomach pain, and nausea. Low blood sugar (hypoglycemia) is possible, especially if you also take diabetes medications. Rare but serious allergic reactions—swelling, wheezing, trouble breathing—have occurred; if that happens, stop and get emergency help.
Can I use fenugreek if I'm on a blood thinner like warfarin?
Fenugreek may add to the blood-thinning effects of drugs like warfarin or clopidogrel, which could raise your bleeding risk. Do not start fenugreek without talking to your doctor or pharmacist first—they need to know about all your medications.
Does fenugreek work for sexual function?
The evidence rates it possibly effective for sexual dysfunction, meaning the research shows promise but isn't definitive. Whether it'll help you depends on your individual situation—talk with your doctor about what to expect.
