Thorne Research Women's Libido Boost Review
Women's Libido Boost is a non-hormonal, plant-based formula from Thorne designed to support a woman's natural sexual well-being, from physical experience to emotional intimacy. According to the page, the product was formulated by Thorne's in-house team of scientists and medical experts and combines clinically studied herbal ingredients intended to support healthy sexual desire and arousal, promote vaginal lubrication, and maintain healthy hormone balance associated with sexual function. The page says benefits may be noticed in as little as two weeks of consistent daily use. Listed benefits include promoting sexual desire and arousal, benefiting vaginal lubrication, supporting sexual wellness and satisfaction, encouraging sexual motivation and intimacy, helping maintain healthy hormone levels associated with sexual function, and enhanced libido as soon as two weeks after beginning daily use. Features listed include a design for adult women of all ages, well-studied botanical ingredients with a long history of traditional use, patented FenuSmart and Liboost extracts, and NSF Certified for Sport status. The page explains that women may experience low libido or changes in libido due to hormonal shifts during perimenopause, menopause, postpartum, or menstrual cycle changes, stress and mental load, fatigue and sleep disruption, emotional well-being, vaginal dryness, and life transitions. The key ingredients are fenugreek seed extract at 500 mg, damiana leaf extract at 300 mg, and shatavari root extract at 100 mg per serving of two capsules. FenuSmart is described as a fenugreek extract standardized to total saponins, protodioscin, and trigonelline, intended to support hormonal and reproductive well-being. Liboost is described as a standardized damiana extract standardized to 1.5 percent total bioflavonoids, intended to support desire, arousal, and lubrication. Shatavari is described as a botanical used in Ayurvedic medicine to support female reproductive health and emotional balance. The page states the product is non-hormonal, contains no hormones or stimulants, is gluten-free, dairy-free, and soy-free, and is taken as two capsules daily with 30 servings per container. The price shown is $48 for 60 capsules, or $43.20 with a subscription. NSF Certified for Sport means every batch is tested for label claim compliance and for the absence of nearly 300 substances banned by many athletic organizations. The warnings state that the product is contraindicated for anyone with a history of hypersensitivity to its ingredients, and that pregnant, nursing, or women trying to conceive should not use it. The page reports no known adverse interactions at publication date.

Study, Trial or Testing Result Summary
Members Only9 human studies · 8 improved
Fenugreek is the main ingredient here, at a dose close to the one studied. In 80 healthy women with low sexual drive, 600 milligrams a day of fenugreek seed extract for 8 weeks raised sexual desire and arousal compared with a placebo [1]. A review of studies in menopausal women found that fenugreek improved sexual function and libido [2]. In a small study of 29 postmenopausal women taking a blend that contained fenugreek, most reported better sexual function, mainly desire [3]. Damiana has only been tested inside multi-ingredient blends, so its own effect is unclear. Two blend trials improved desire in women [4][5], but a larger trial in 186 women who had survived cancer found no effect on desire or sexual function [6]. Shatavari is included at 100 milligrams per serving, below the 300 milligrams a day that raised sexual function scores in women with low libido [7]. Taking three servings a day reaches that amount. Other trials found shatavari improved sexual function and satisfaction [8] and eased loss of libido and vaginal dryness during menopause [9]. Animal and cell studies are never counted.

Review Totals and Summary
Members Only39 reviews · 36% positive
Thorne's page shows 39 ratings in total, and the themes below come from the five written reviews that could be read on that page, so they are individual experiences and not a full picture of every buyer. The feedback splits sharply, and the star average of 2.7 out of 5 reflects that. It is pulled down by a large number of one-star ratings, even though the written comments are few and mixed. The helpfulness votes on the reviews are small, so no single opinion stands out as the consensus. What buyers praise: three reviewers were positive. Vanessa R., who titled her review "Feel great," says the product has helped her over the weeks and describes a clear improvement she loves. Kimberly S., a verified buyer, headed her review "Definitely works," says she loves the product and plans to keep taking it daily. Janet G. calls it a "Great Product," says it works, and says it has lifted her spirit with continued use. People who report results describe a gradual lift in mood and satisfaction that builds with steady use. Their comments centre on sustained daily use over time, which matches the page's own guidance that results can take a few weeks of consistent use. What buyers complain about: two reviewers saw little or nothing. Lynn r. says she does not feel any different after taking it for over a month. Lacie Z. rates it "Ok" and says she did not notice much of a change. Both describe the same daily routine as the happier reviewers, without any shift in how they feel, even after a month or more of daily dosing. Who it seems to suit: the reviews suggest it may suit people willing to take it every day for several weeks and wait for gradual effects, particularly those looking for a lift in mood and satisfaction. Those who stopped expecting changes after a month or so did not report benefits, so patience alone does not guarantee a result. The written comments do not say anything about age, health background or other personal factors that might explain why some people responded and others did not. Taste, form and value: none of the readable reviews mention taste, capsule size, ease of swallowing, price or value for money, so there is nothing to report on those points. Any reviews of other forms of this product, such as gummies or powder, were left out, and this summary covers the capsules only. Overall, the written feedback shows a divide between people who felt a benefit with continued daily use and people who noticed no effect, and with only five comments readable there is no clear majority view.
Biohacker Summary
Members Only7 of 10 recommend it
Fenugreek is the main ingredient here, and the panel is split but leans positive: four of the seven who spoke about it currently recommend it, two warn against it, and the rest are neutral. Those who recommend it mostly take it for blood sugar and insulin, with others citing period pain, inflammation, and testosterone or libido support. Forms mentioned include capsules, tea, extract, and seeds soaked overnight and eaten before meals. No doses were given, though one panelist cited a 5 to 20 percent drop in blood sugar spikes. On the caution side, one panelist says it has been disproven for testosterone, another says it raises testosterone too little to build muscle, and one felt overly wired from it because of how he processes certain brain chemicals, while another found apple cider vinegar worked better for blood sugar.

RAL Summary
Members OnlyTier 4 for Libido for Women
The studies support fenugreek and shatavari for women's libido, but only 40% of 48 reviews are positive. This is below the two-thirds needed for a higher tier and not a negative majority, so the evidence and buyers disagree.
Take 3 servings a day (6 capsules) to match the dose that worked in the studies.
- Emerging: not enough evidence to rank higher yet.
Where the evidence disagrees: 1 of the 9 human studies found no effect.
More Details
Members OnlyBody systems · Combine with · Possible side effects
Body systems: Reproductive system, Endocrine system, Nervous system
Combine with: For adrenal support, pair with adaptogens such as ashwagandha (KSM-66 or Sensoril) or Rhodiola rosea to help moderate the stress response and cortisol. Add vitamin C, B-complex (especially pantothenic acid B5 and B6), and magnesium glycinate to support adrenal hormone synthesis and nervous system balance. For libido goals, maca root, L-arginine, and zinc can complement a libido formula, while adequate sleep and stress reduction help both areas. Check with a healthcare provider before combining, especially if you take hormonal medications, have a thyroid condition, or are pregnant or breastfeeding.
Possible side effects: One shatavari trial reported no significant side effects. The readable reviews did not mention side effects.
