HelloPharmacist Scorecard of Fem Libido by Protocol For Life Balance
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.
What’s inside
Full disclosure
Fem Libido contains two active ingredients. Maca is a root traditionally used for sexual function and reproductive health, though the evidence for most uses is not yet established.
Fenugreek extract is derived from fenugreek seeds and has some evidence suggesting it may support sexual function and arousal. The product also contains inactive ingredients — cellulose, stearic acid, and silica — which are fillers and binders that hold the capsule together.
Does it work?
Moderate evidence
For fenugreek extract, there is possibly effective evidence for sexual dysfunction and sexual arousal, and some evidence for dysmenorrhea and diabetes support. For maca, the evidence isn't established in the data we hold — uses like amenorrhea, athletic performance, and osteoporosis all have insufficient reliable evidence to rate at this time.
If you're considering this product for a specific concern, chat with your pharmacist about what the research actually shows for your situation.
How safe is it?
Well-documented data
Fenugreek is generally well tolerated in food amounts, but supplement doses can cause side effects in some people, most commonly abdominal pain, bloating, diarrhea, nausea, and flatulence. Rare but serious allergic reactions — including bronchospasm (airway constriction), swelling, and shock — have been reported.
Maca is generally well tolerated as a food, though fresh uncooked maca may cause stomach pain; long-term supplement safety hasn't been well studied. Neither ingredient should be used during pregnancy due to insufficient safety data.
Fenugreek is sometimes used to support milk supply while breastfeeding, but the evidence is limited — talk with your doctor or lactation consultant first.
Meds to double-check
Moderate interaction found
Check with your pharmacist before taking this product if you're on blood thinners (anticoagulants) or antiplatelet drugs like warfarin or clopidogrel, diabetes medications, metoprolol or other blood pressure drugs, theophylline, phenytoin (an anti-seizure drug), or sildenafil (Viagra). All are documented Moderate-severity interactions with fenugreek.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Fem Libido may be worth considering if you're looking for a supplement for sexual function and you don't take blood thinners, diabetes medications, heart drugs, or anti-seizure meds. If you take any of those, or if you have a history of allergies, check with your pharmacist before starting.

Fem Libido by Protocol For Life Balance Drug Interactions
HelloPharmacist Interaction Report
Fem Libido by Protocol For Life Balance contains two active ingredients.
Fenugreek extract has documented interactions with a number of medication types; maca was checked and has no known interactions. The most serious concern is with blood thinners (anticoagulants) and antiplatelet drugs — fenugreek may add to their effects and increase bleeding risk, particularly with warfarin and clopidogrel.
Read the full breakdown — every affected drug type, severity by severity
Fenugreek also interacts moderately with diabetes medications (it can lower blood sugar further), theophylline (a breathing medication), metoprolol (a heart and blood pressure drug), phenytoin (an anti-seizure medication), and sildenafil (Viagra). In each case, fenugreek may reduce how well the medication works or increase its side effects.
Also note: fenugreek can cause allergic reactions in some people, ranging from mild itching to serious breathing problems and swelling. If you take any blood thinners, diabetes drugs, heart or blood pressure medications, anti-seizure drugs, or ED medications, check your exact drugs with the tool below before starting this product.

Fenugreek extract
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 .
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.
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%.
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.
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.
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.
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%.
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.
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.
