Libifem® is a clinically studied fenugreek seed extract developed specifically for women's wellbeing. Explore its potential benefits for sexual wellbeing, exercise performance and body composition, including the 600mg dose used in human research.
What Is Libifem®?
Libifem® is a branded, standardised extract of fenugreek seeds (Trigonella foenum-graecum), developed for women's health and wellbeing. It contains naturally occurring plant compounds called saponins and has been investigated in placebo-controlled human studies for sexual desire, arousal, strength and body composition.
600mg per day is the dose used in several key clinical trials. In an eight-week study involving 80 women, Libifem® improved selected measures of sexual desire and arousal compared with placebo. A separate exercise study reported improvements in leg-press strength and body composition at the same daily dose.
Research: 2015 clinical trial and 2023 exercise trial.
Why Is Libifem® Used in Women's Supplements?
Libifem® provides a standardised form of fenugreek that has been studied specifically in women. Its clinical research has focused on sexual wellbeing and, more recently, selected measures of strength and body composition alongside exercise.
Research-backed amount
600mg per day
Used in multiple placebo-controlled trials, commonly over eight weeks.
What Exactly Is Libifem®?
Libifem® is a proprietary extract made from the seeds of Trigonella foenum-graecum, better known as fenugreek.
Fenugreek is a plant in the legume family. Its seeds have a long history of culinary and traditional use, and contain several naturally occurring compounds, including steroidal saponins.
Libifem® uses a specialised extraction and standardisation process. It is standardised to more than 50% Fenuside™, a proprietary specification associated with its saponin content.
This standardisation is relevant because it allows researchers to study a more consistent ingredient rather than relying on fenugreek powders with potentially different compositions.
Why the branded ingredient matters
When a clinical trial uses Libifem®, the results apply to that specific studied extract, dose and population. They should not automatically be applied to every generic fenugreek supplement.
Libifem® vs Ordinary Fenugreek: What's the Difference?
Both come from the same plant, but the formulation and clinical evidence are important differences.
| Feature | Libifem® | Generic fenugreek |
|---|---|---|
| Botanical source | Trigonella foenum-graecum seeds | Usually the same plant species |
| Form | Standardised branded extract | Powder, whole seeds or extracts |
| Standardisation | More than 50% Fenuside™ | Depends on the product |
| Human research | Specific clinical studies in women | Evidence depends on the extract tested |
| Studied daily amount | 600mg in several key trials | No universally equivalent dose |
For anyone comparing ingredients, the useful questions are whether the extract is standardised, how much is included per serving and whether the supporting studies used the same ingredient.
03 / Potential benefitsWhat Are the Potential Benefits of Libifem® for Women?
1. Sexual Desire and Arousal
One of the most studied applications of Libifem® is female sexual wellbeing.
In a randomised, double-blind, placebo-controlled study, researchers investigated 600mg of Libifem® daily in healthy menstruating women who reported low sexual desire.
After eight weeks, the Libifem® group showed significant improvements in measures of sexual desire and arousal compared with placebo.
The researchers also observed changes in free testosterone and estradiol levels. These findings describe hormone measurements within that trial and should not be interpreted as proof that every woman needs or benefits from higher hormone levels.
Read the published 2015 clinical trial.
2. Strength During Exercise Training
Libifem® has also been studied in physically active women completing a structured exercise programme.
A 2023 trial compared 600mg Libifem®, 300mg Libifem® and placebo over eight weeks, alongside whole-body exercise three times per week.
The 600mg group showed a greater improvement in leg-press one-repetition maximum than placebo. This is an encouraging finding for researchers investigating women's strength and training outcomes.
3. Body Composition
The same exercise trial reported favourable changes in total fat mass and lean mass in the 600mg group.
These findings are promising, although they come from a relatively small, short-term study conducted alongside a structured exercise programme. They should not be treated as evidence that Libifem® produces the same results without training.
What the evidence supports
Libifem® has ingredient-specific human research showing improvements in selected sexual wellbeing measures and encouraging results for strength and body composition alongside exercise. Further independent research would help establish how consistently these findings apply to different groups of women.
What Do the Libifem® Human Studies Show?
2015: Sexual Wellbeing in 80 Women
Published in Phytotherapy Research, this randomised controlled trial enrolled 80 healthy menstruating women aged 20–49 who reported low sexual drive.
Participants received either 600mg Libifem® daily or placebo over two menstrual cycles, approximately eight weeks.
Researchers used established questionnaires to measure different aspects of sexual function and collected blood samples to examine selected hormone levels.
Key findings: The Libifem® group showed significant improvements in sexual desire and arousal compared with placebo, alongside changes in free testosterone and estradiol.
2023: Exercise Performance and Body Composition
Published in Frontiers in Sports and Active Living, this trial investigated Libifem® in women aged 25–45 completing an eight-week exercise programme.
Participants were assigned to one of three groups: 600mg daily, 300mg daily or placebo.
All groups completed whole-body exercise three times per week.
The researchers also reported a significantly greater increase in lean mass in the 600mg group compared with both the 300mg and placebo groups.
The study reported that 128 participants were enrolled and randomised, but the final analysed group sizes were smaller. This matters when assessing how confidently the findings can be generalised.
Important distinction
The body-composition results were observed alongside regular exercise. The study does not establish Libifem® as a standalone weight-loss product, and the findings do not guarantee the same changes for other individuals.
Why Is 600mg the Studied Libifem® Dose?
600mg per day is the dose used in several published Libifem® trials. It is especially relevant because the 2015 sexual wellbeing study and the 2023 exercise study both investigated this amount.
| Daily amount | Research context | Outcome |
|---|---|---|
| 300mg | 2023 exercise study | Investigated as a lower-dose comparison; not all benefits seen at 600mg were observed |
| 600mg | 2015 sexual wellbeing study | Improved selected measures of sexual desire and arousal |
| 600mg | 2023 exercise study | Favourable findings for leg-press strength and body composition |
Some studied protocols have divided the daily amount into two 300mg servings. The appropriate schedule for any commercial supplement should follow its current label and professional advice where relevant.
How Long Does Libifem® Take to Work?
The featured studies assessed outcomes over approximately eight weeks. They do not establish that a single serving produces an immediate benefit.
For consumers comparing the evidence, the study duration is as important as the daily amount.
06 / Active womenIs Libifem® Relevant to Women Who Train?
The 2023 trial provides an interesting research direction for women who combine resistance training with general fitness or conditioning.
The strongest exercise-related findings involved leg-press strength and selected body-composition measurements. The trial did not establish improvements across every measured exercise outcome.
For women interested in strength and performance, Libifem® is an ingredient worth understanding alongside the fundamentals of training, sufficient energy intake, protein and recovery.

07 / SafetyWho Should Not Take Libifem®?
Libifem® has been studied in adult women, but the available clinical evidence does not establish safety for every population.
Who should avoid Libifem®?
Libifem® should not be used during pregnancy or breastfeeding, or by anyone under 18, unless a suitably qualified healthcare professional has specifically advised otherwise. The featured trials do not establish safety in these groups.
Pregnancy
Avoid concentrated Libifem® supplements during pregnancy. Fenugreek preparations may have physiological effects, and the cited Libifem® trials were not designed to establish pregnancy safety.
Breastfeeding
Avoid Libifem® during breastfeeding without specialist medical advice. Traditional uses of fenugreek do not establish the safety of a concentrated, standardised extract for a breastfeeding parent or infant.
Under 18
The clinical studies discussed here involved adults. Safety and effectiveness for children and teenagers have not been established.
Medication and Existing Health Conditions
People taking medication, particularly for blood glucose or blood clotting, should consult a healthcare professional before using concentrated fenugreek extracts. Anyone with a hormone-sensitive condition should also seek advice because some studies have reported changes in measured sex hormones.
Fenugreek belongs to the legume family. People with relevant food allergies should check the product and seek advice before use.
Although the featured trials provide useful short-term tolerability information, longer-term safety and medication-interaction data remain limited.
