Shatavari for Perimenopause: What the Evidence Says
A look at the small but growing trial base behind shatavari, plus what happens when a studied extract meets a buyable capsule.
Shatavari for perimenopause: what the evidence says
If you’re dealing with hot flashes, broken sleep, or a mood that feels more volatile than usual, you’re not imagining it. Perimenopause can bring all of that, often in a frustrating mix. Shatavari is one of the newer ingredients showing up in perimenopause supplements, including Ritual’s Perimenopause Health and Balterra’s products.
The headline is promising. The detail is smaller. Controlled studies are few, and they do not all test the same extract, dose, or population. The useful question is not “Does shatavari work?” It is “What was studied, and does the bottle match?”
What shatavari is
Shatavari is Asparagus racemosus, a plant in the asparagus family. The supplement is made from the root. Its root contains steroidal saponins, including shatavarins, plus flavonoids and other compounds. The exact chemistry varies by plant and extraction method, so “shatavari” on a label is not enough. Look for the extract ratio and standardization, not just the herb name.
Traditional use is not a clinical trial. Active components and long-term safety remain incompletely characterized. LactMed
Benefit by benefit
Hot flashes and night sweats. This is the most visible claim. A 2025 randomized, double-blind, placebo-controlled study enrolled 80 women aged 40–55 with perimenopausal symptoms. Seventy-three completed the study. Participants took a standardized shatavari root extract, 300 mg once daily, for eight weeks. The extract used a 13:1 herb-to-extract ratio and more than 10% total shatavarins. Compared with placebo, the shatavari group had a larger reduction in hot-flash frequency and broader Menopause Rating Scale scores. The study did not report adverse events. Mahajan et al., 2025
That is encouraging, but it is one small, eight-week study with 73 completers. A 2024 trial used a different extract, standardized to 5% total shatavarins, at 250 mg twice daily for 60 days. It reported improvements in several symptoms, with mild dizziness and bloating. Gudise et al., 2024
Stress, mood, and sleep. In the 2025 perimenopause trial, perceived stress improved more than placebo at weeks four and eight. Fatigue improved at week eight, and vigor improved at week four. Not every mood subscore changed. A separate 2025 trial found clear reductions in overall menopause and stress scores, but some hot-flash, quality-of-life, and hormonal results were trends, not statistically significant differences.

Vaginal dryness. One 2024 study reported improvement, and Ritual’s product page claims shatavari supports vaginal dryness. But Ritual blends shatavari with DIM, vitamin B6, and evening primrose oil, so a blend result cannot be assigned to shatavari alone. Vaginal symptoms can also need local care, not just a capsule.

Studied dose versus a buyable dose
There is no established general dose range for shatavari. Dose depends on the extract, not just the front-label milligrams. One perimenopause study used 300 mg daily of a highly standardized extract. Another used 500 mg daily of a 5%-shatavarin extract. Those are not interchangeable equivalents.
Ritual’s current Perimenopause Health label lists 100 mg of shatavari extract per capsule, alongside 60 mg DIM, 0.9 mg vitamin B6, and 250 mg evening primrose oil. Ritual says the shatavari is a clinically studied form and recommends one capsule daily. The page lists the extract amount, but its public product page does not clearly show the same 13:1 ratio and greater-than-10% shatavarins specification used in the 300 mg perimenopause trial. Ritual product page
That does not prove Ritual is ineffective. It does mean the dose-fit claim deserves a question mark. A lower amount may be deliberate if the extract is more concentrated, but the label should let you verify that. Ritual is an affiliate partner of PeriProof. We mention the product for the label comparison; that relationship does not change the evidence read.
Safety and the parts we still don’t know
Short-term trials generally reported no serious safety signal, with mild dizziness, bloating, or nausea appearing in some studies. That is reassuring, not a blanket clearance. Human safety data are limited, especially for long-term use, and supplement quality varies. WebMD
Get individualized advice before using it if you are pregnant, have an asparagus allergy, have an estrogen-sensitive condition, or take prescription medicines. Shatavari contains compounds described as phytoestrogens, so hormone-sensitive history deserves a clinician’s review. Interaction data are incomplete, and the Menopause Society recommends discussing supplements with a healthcare professional, especially when taking hormone therapy or managing a medical condition.

For a brand-by-brand read of the capsule that contains shatavari, see our Ritual Perimenopause Health review. The label and evidence still do not line up perfectly.
Bottom line: shatavari is a plausible option for someone who wants a non-hormonal supplement and understands the thinness of the evidence. The most defensible products identify the extract, standardization, and exact dose. The least convincing promise is a generic “hormone balance” claim with no numbers. This is an evidence read, not medical advice, and a supplement is not a substitute for medical care.
