Does ashwagandha help with digestive changes during perimenopause?

Digestive changes during perimenopause are genuinely common and genuinely confusing. Many women notice increased constipation, looser stools, more gas, or a gut that just seems more reactive than it used to be. Several factors converge here: estrogen and progesterone both influence gut motility, and as they fluctuate, the intestines respond. Stress also plays a major role through the gut-brain axis. Ashwagandha does not act directly on the gut, but by lowering cortisol and calming the HPA axis, it addresses the stress-driven disruption that is often amplifying perimenopausal digestive changes.

There are no clinical trials testing ashwagandha specifically for digestive changes in perimenopausal women. What does exist is evidence that ashwagandha significantly reduces cortisol and perceived stress, and a well-established body of research showing that high cortisol directly disrupts gut function in multiple ways: it slows gastric emptying, alters intestinal permeability, shifts gut microbiome composition toward dysbiosis, and reduces mucosal immune function. A 2015 review in Gut noted that psychological stress reliably worsens gastrointestinal symptoms across a broad range of conditions. If ashwagandha reduces the cortisol that is driving this disruption, some digestive benefit is biologically plausible, though it has not been directly tested. Treat the evidence as preliminary and indirect.

The gut is unusually sensitive to hormonal change during perimenopause because estrogen receptors (particularly ER-beta) are distributed throughout the gastrointestinal tract. These receptors influence motility, secretion, and gut barrier integrity. When estrogen levels become unpredictable, gut behavior follows suit, sometimes becoming constipated when estrogen is low and more reactive when it spikes. Progesterone has a relaxing effect on smooth muscle throughout the body, including the intestines. As progesterone levels fall during perimenopause, some women experience faster transit and looser stools. Ashwagandha does not replace either hormone, but by reducing cortisol-driven gut dysregulation, it may smooth out some of the additional stress reactivity layered on top of the hormonal changes.

Studies have used 300 mg of KSM-66 twice daily or 240 to 600 mg of Sensoril once daily. For people with digestive sensitivity, starting at the lower end (around 250 mg once daily with food) is sensible, since nausea and loose stools are the most commonly reported side effects at higher doses. Taking ashwagandha with a meal rather than on an empty stomach also reduces GI side effects and improves absorption of its fat-soluble compounds. Talk to your healthcare provider about the right dose for your situation, especially if you have diagnosed GI conditions such as IBS or IBD.

Ashwagandha may be more effective for digestive changes when combined with a high-quality probiotic, which directly supports microbiome composition. Adequate fiber and regular meal timing also support gut motility in ways that complement ashwagandha's stress-reducing effect. Avoid high-dose ashwagandha on an empty stomach. If you take prescription medications, check with your provider before adding this supplement. Ashwagandha has thyroid-stimulating effects and may interact with immunosuppressant medications.

For digestive symptoms that have a strong stress component, some women notice improvement in gut reactivity within three to four weeks. Changes in motility patterns (constipation or loose stools) that are hormonally driven may be less responsive to ashwagandha than stress-triggered symptoms. This is not a quick fix, and it is unlikely to resolve digestive changes that are primarily hormonal in origin. It works best as one component of a broader approach that also includes dietary changes and stress management.

See a doctor if your digestive changes include blood in the stool, unintended weight loss, persistent abdominal pain, or symptoms that have changed significantly and recently. These are not perimenopausal side effects that supplements address. Conditions like celiac disease, inflammatory bowel disease, SIBO, or colorectal changes all need medical diagnosis. A provider can also check whether your thyroid is contributing to your GI symptoms, since hypothyroidism commonly causes constipation and worsens during the menopausal transition.

Log your digestive comfort on a 1 to 10 scale each day alongside your stress level, noting whether your gut feels worse on high-stress days or around specific parts of your cycle. Do this for two weeks before starting ashwagandha and continue for six weeks after. The PeriPlan app makes cycle-phase tracking easy, which helps you identify whether your digestive symptoms are hormonally timed (and need a different intervention) or stress-amplified (where ashwagandha is more likely to help).
