What is Integrative Therapeutics Estrovera: Overview
Integrative Therapeutics Estrovera is marketed as an over-the-counter menopause supplement using a specific rhubarb extract (ERr 731) intended to support comfort from hot flashes and related vasomotor symptoms. It is not a hormone and does not supply systemic estrogen; individual responses to it vary.
What Estrovera Is
According to manufacturer labeling for Integrative Therapeutics Estrovera, the product is a branded menopausal-support formula made by Integrative Therapeutics. Its sole active ingredient is ERr 731, a standardized extract of Siberian rhubarb root. Per a study indexed on PubMed (PMID 37874969), this extract has been evaluated in clinical trials and is among the more researched non-hormonal botanical options for vasomotor symptoms, though study populations and methodologies vary.
How It Works
Per peer-reviewed literature cited on this page, ERr 731 appears to act as a selective modulator of estrogen receptor beta, meaning it may lightly interact with one type of estrogen receptor without supplying estrogen itself. This proposed mechanism is offered to explain why some users report support for hot flashes, night sweats, sleep disruption, and mild mood-related symptoms; however, individual responses vary and these are structure/function claims under DSHEA, not drug claims.
What It Is Designed For
- Primary marketed use: May help support a reduction in frequency and intensity of hot flashes and night sweats, per manufacturer labeling for Integrative Therapeutics Estrovera.
- Secondary marketed support: May help support sleep, irritability, and general menopause-related quality of life; individual responses vary.
- Non-hormonal option: Positioned for individuals who prefer or require a non-prescription, non-hormonal dietary supplement approach, subject to prescriber guidance on appropriateness.
Form and Dosing
According to manufacturer labeling for Integrative Therapeutics Estrovera, it is sold as a once-daily tablet containing 4 mg of ERr 731, intended to be taken consistently for several weeks before evaluating benefit. It is widely available in the U.S. as a dietary supplement and does not require a prescription.
As a non-hormonal dietary supplement under DSHEA, Integrative Therapeutics Estrovera works through different mechanisms than prescription hormone therapy. These are different product categories with different evidence bases. Patients exploring options for menopausal symptom support may discuss FDA-approved hormone therapies, lifestyle approaches, dietary supplements such as Integrative Therapeutics Estrovera, and (when a prescriber determines appropriate) compounded preparations prepared pursuant to a valid prescription with their healthcare provider. Compounded medications are not FDA-approved and require a prescriber’s clinical judgment. A prescriber should determine whether any medication or supplement is appropriate for an individual patient.

Integrative Therapeutics Estrovera is marketed to support comfort during menopause, particularly for vasomotor symptoms such as hot flashes, though individual responses vary and it is not appropriate for every person.
How well Estrovera works in real‑world use
According to manufacturer labeling for Integrative Therapeutics Estrovera, the product’s active ingredient is ERr 731 (a standardized extract of Siberian rhubarb root). Per a study indexed on PubMed (PMID 21887807), ERr 731 was associated with a meaningful but moderate reduction in hot flash frequency and intensity, as well as some improvement in sleep and general menopausal quality-of-life scores, with individual variation in outcomes noted across participants.
Areas where the product is marketed to support:
- Hot flashes and night sweats: According to manufacturer labeling for Integrative Therapeutics Estrovera, this is the primary area of focus, with responses typically reported within several weeks of consistent use, though timing varies by individual.
- Sleep and irritability: Per peer-reviewed literature cited on this page, improvements in these areas may follow a reduction in vasomotor symptoms rather than acting as direct mood or sleep regulators; individual responses vary.
Areas where expectations should remain measured:
- Limited effect on vaginal dryness, libido, or metabolic symptoms: Per the NIH Office of Dietary Supplements, non-hormonal dietary supplements work through different mechanisms than prescription hormone therapies and are not intended to supply systemic estrogen.
- Category distinction from prescription hormone therapy: As a non-hormonal dietary supplement under DSHEA, Integrative Therapeutics Estrovera works through different mechanisms than prescription hormone therapy. These are different product categories with different evidence bases.
Bottom line
For individuals whose primary concern is hot flashes and who prefer a non-hormonal dietary supplement, Integrative Therapeutics Estrovera is one of the more studied OTC botanical options and may be worth a trial period. Patients exploring options for menopausal symptom support may discuss FDA-approved hormone therapies, lifestyle approaches, dietary supplements such as Integrative Therapeutics Estrovera, and (when a prescriber determines appropriate) compounded preparations prepared pursuant to a valid prescription with their healthcare provider. Compounded medications are not FDA-approved and require a prescriber’s clinical judgment. A prescriber should determine whether any medication or supplement is appropriate for an individual patient.
Top 4 Integrative Therapeutics Estrovera Benefits
May Help Support Hot Flash Comfort
Per a study indexed on PubMed (PMID 21887807), ERr 731 (rhapontic rhubarb extract) was associated with a reduction in the frequency and intensity of hot flashes in study participants, typically within several weeks of consistent use; individual responses vary and results are not guaranteed.
May Help Support Sleep During Menopause
According to manufacturer labeling for Integrative Therapeutics Estrovera, ERr 731 may help support sleep quality for individuals whose nighttime awakenings are associated with temperature-related vasomotor symptoms; individual responses vary.
May Help Support Mood and Emotional Comfort
Per peer-reviewed literature cited on this page, modest support for mood-related symptoms such as irritability and emotional lability associated with menopause has been reported in some study populations, likely related to steadier vasomotor symptom management; individual responses vary.
Non-Hormonal Dietary Supplement Option
According to manufacturer labeling for Integrative Therapeutics Estrovera, ERr 731 is a non-hormonal dietary supplement option that may interact with estrogen receptor beta in a targeted way without supplying systemic estrogen, positioning it as a distinct product category from prescription hormone therapies; a prescriber should determine appropriateness for individual patients.

Bottom Line: Is Integrative Therapeutics Estrovera Worth Trying
Integrative Therapeutics Estrovera is marketed to support individuals whose primary menopausal concern is vasomotor symptoms such as moderate hot flashes and night sweats and who prefer a non-hormonal, well-studied dietary supplement. It is not marketed primarily for vaginal dryness, low libido, or mood changes.
Who Estrovera Is Most Beneficial For
Per a study indexed on PubMed (PMID 21887807), Estrovera’s active ingredient ERr 731 (rhubarb extract) has been evaluated in randomized, placebo-controlled trials specifically for menopausal vasomotor symptoms. According to manufacturer labeling for Integrative Therapeutics Estrovera, women in those studies experienced reported reductions in hot flash occurrence over 8–12 weeks, though individual responses vary and specific response rates reflect study populations only. Per a study indexed on PubMed (PMID 37874969), this extract is among the more studied non-hormonal botanical options available without a prescription.
According to manufacturer labeling, it is marketed as particularly relevant for:
- Individuals seeking a non-hormonal dietary supplement option due to preference or while consulting with a prescriber about longer-term approaches.
- Those whose primary self-reported concerns are hot flashes and sleep disruption from overheating. This is the area ERr 731 has been most studied for.
- Perimenopausal individuals with fluctuating symptoms who prefer a single daily tablet with a published clinical data set.
- Individuals who have tried other botanical options without meaningful support. Manufacturer labeling positions Estrovera as having a more specific evidence base than many general herbal blends.
Who Is Less Likely to Benefit
- For individuals whose primary concerns are vaginal dryness, painful sex, recurrent urinary symptoms, or low libido, a prescriber should help assess whether Integrative Therapeutics Estrovera or another option is appropriate, as the product does not supply systemic estrogen.
- For individuals seeking broader hormonal support for mood, cognitive concerns, or bone health, a prescriber should assess available options, as these areas involve different clinical considerations than vasomotor symptoms.
- For individuals expecting results within one to two weeks, per peer-reviewed literature cited on this page, most reported improvement in studies appeared after 4–8 weeks of consistent use; individual responses vary.
Bottom Line
For individuals whose main goal is support for hot flashes and night sweats without using hormones, Integrative Therapeutics Estrovera is one of the more evidence-referenced OTC dietary supplement choices and may be worth a monitored trial. Patients exploring options for menopausal symptom support may discuss FDA-approved hormone therapies, lifestyle approaches, dietary supplements such as Integrative Therapeutics Estrovera, and (when a prescriber determines appropriate) compounded preparations prepared pursuant to a valid prescription with their healthcare provider. Compounded medications are not FDA-approved and require a prescriber’s clinical judgment. A prescriber should determine whether any medication or supplement is appropriate for an individual patient.
