Does ashwagandha help with mood swings during perimenopause?

Mood swings during perimenopause are not about being emotionally unstable. They are a physiological response to rapidly shifting hormone levels that directly affect brain chemistry. Estrogen influences serotonin, dopamine, and GABA, the three neurotransmitters most involved in emotional regulation. When estrogen fluctuates, these systems fluctuate with it. Ashwagandha works on this picture from the stress side: it lowers cortisol, modulates GABA receptors, and may support serotonin pathways, which can collectively reduce the amplitude of mood shifts even when estrogen remains unpredictable.

The clinical evidence for ashwagandha and mood is reasonably strong. A 2019 randomized double-blind placebo-controlled trial in Medicine found that 240 mg of a standardized ashwagandha extract significantly reduced anxiety and morning cortisol levels after 60 days. A 2012 study in the Indian Journal of Psychological Medicine found that 300 mg twice daily significantly reduced stress and anxiety scores while improving quality-of-life measures. These are not perimenopause-specific trials, but mood disturbance driven by stress-axis dysregulation is exactly what they targeted. A 2021 study in the Journal of Obstetrics and Gynaecology Research specifically in menopausal women found improvements in total menopausal symptom scores including psychological symptoms. The evidence here is among the most solid for any supplement in the mood-support category.

Perimenopause creates a unique mood vulnerability because estrogen decline directly removes a protective buffer from the brain. Estrogen promotes serotonin receptor density and slows serotonin breakdown. When it drops, serotonin activity becomes less stable, which translates to faster emotional reactivity and slower recovery. At the same time, progesterone's calming effects on GABA receptors also diminish, removing another layer of emotional buffering. Cortisol, running high due to sleep disruption and the body's stress of adapting to hormonal change, amplifies amygdala reactivity, making small frustrations feel large. Ashwagandha works on the cortisol and GABA pieces of this picture directly.

Studies on ashwagandha for mood and stress have used 240-600 mg daily of a standardized root extract, with some trials using split dosing of 300 mg twice daily. The most studied forms are KSM-66 and Sensoril. Trials have typically run for 8-12 weeks, which is the minimum reasonable window to evaluate mood changes. Because mood is influenced by so many variables (sleep, food, exercise, relationship stress), a consistent supplement trial with daily symptom logging gives you the best chance of detecting a real signal. Talk to your healthcare provider about the right dose for your situation.

Ashwagandha pairs reasonably with magnesium glycinate for mood support, since magnesium supports GABA function through a complementary mechanism. Reducing caffeine and alcohol, which both dysregulate cortisol and sleep, will amplify any benefit. If you are already taking antidepressants, anxiolytics, or mood stabilizers, discuss adding ashwagandha with your provider first. Ashwagandha has mild GABAergic activity and its interaction with SSRIs and SNRIs has not been fully characterized. Do not use it as a substitute for prescribed mood medication.

Mood-related changes from ashwagandha tend to appear earlier than some other effects, typically within 4-6 weeks of consistent use. Cortisol normalization is often the first sign: you may notice you feel slightly less reactive in the late afternoon or that recovery from stress feels faster. Full mood stabilization, if it happens, usually takes 8-12 weeks. Expect gradual improvement, not a sudden shift. The women who report the strongest response tend to be those with high baseline stress levels.

Some mood changes during perimenopause do warrant professional support rather than a supplement approach. If you are experiencing persistent low mood lasting more than two weeks, loss of interest in things you normally enjoy, significant changes in appetite or sleep that go beyond the typical perimenopausal pattern, or thoughts of self-harm, please reach out to your healthcare provider or a mental health professional. These are clinical depression patterns, not just mood swings, and they respond to evidence-based treatment that a supplement cannot replace.

Tracking mood daily on a 1-10 scale and noting the timing of shifts relative to your cycle, sleep quality, and cortisol-heavy days helps you see patterns that daily experience obscures. PeriPlan lets you log mood alongside other symptoms so you can see whether bad mood days cluster around certain cycle points or consistently follow poor sleep nights. That level of self-knowledge is genuinely useful, both for your own understanding and for conversations with your provider.
