Why Ashwagandha Is One of the Most Relevant Adaptogens for Perimenopause
Ashwagandha (Withania somnifera) is one of the most studied adaptogens in the world, and its areas of demonstrated benefit map closely to the most common perimenopause concerns. It has been shown in clinical trials to reduce cortisol levels, lower perceived stress and anxiety, improve sleep onset and quality, and support thyroid function. Some research also suggests it may support hormonal balance by modulating the hypothalamic-pituitary-adrenal axis, which governs the stress response and interacts with reproductive hormones. During perimenopause, when the hormonal transition is already placing stress on the body's regulatory systems, reducing the cortisol burden can have downstream benefits on mood, energy, and sleep. Ashwagandha is not a hormone replacement, but it can be a meaningful support tool.
KSM-66 vs. Sensoril: Understanding Extract Types
Most high-quality ashwagandha supplements use one of two patented extract standards: KSM-66 or Sensoril. Both are made from Withania somnifera root and standardized to contain specific concentrations of the active compounds called withanolides. KSM-66 is derived primarily from the root and uses a full-spectrum extraction process. It has the most extensive clinical trial record, with research supporting its use for stress reduction, sleep quality, physical endurance, and hormonal support in women. Sensoril uses both root and leaf material and tends to have a higher concentration of withanolides per dose, but fewer published clinical trials than KSM-66. A third extract standard called Shoden is newer and claims very high withanolide content, with some emerging research. For most women, KSM-66 represents the most evidence-backed choice due to the depth of clinical research behind it.
What Dosage Research Supports
Most clinical trials showing benefits for stress, anxiety, and sleep quality have used doses ranging from 300mg to 600mg of standardized extract daily. The 600mg dose has been used in several well-designed studies and tends to produce the most consistent results for cortisol reduction and sleep quality. Doses can be taken as a single daily dose or split into morning and evening. Some women find that taking ashwagandha in the evening supports sleep more directly. Starting with a lower dose, around 300mg, for the first few weeks is a sensible approach to assess tolerance before increasing. The benefits of ashwagandha tend to build over four to eight weeks of consistent daily use rather than being immediate, so patience matters.
What to Look for on the Label
The most reliable supplements will specify the extract standard, either KSM-66 or Sensoril, the withanolide percentage in the extract, and the dose of extract per serving. Avoid products that list only a proprietary blend without specifying what percentage of the blend is ashwagandha, or that do not disclose the extract standard. Third-party testing certifications provide additional confidence in label accuracy and purity. Ashwagandha has a naturally strong, earthy smell and taste. Some capsule products are coated or use odorless extraction processes. If that matters to you, it is worth checking reviews for comments on taste and smell before buying.
Who Should Be Cautious With Ashwagandha
Ashwagandha is generally well tolerated, but there are some groups who should use it with caution or discuss it with a doctor before starting. Women with autoimmune conditions, including Hashimoto's thyroiditis, lupus, and rheumatoid arthritis, should be cautious because ashwagandha can stimulate immune function, which may worsen these conditions in some people. It is also in the nightshade family, and some people with nightshade sensitivities report reactions. Ashwagandha is not recommended during pregnancy. If you are taking medications for thyroid disorders, diabetes, or immunosuppression, checking with your doctor before adding ashwagandha to your regimen is worth doing since it can interact with those medications.
Combining Ashwagandha With Other Adaptogens
Ashwagandha is often combined with other adaptogens in comprehensive stress or adrenal support formulas. Rhodiola rosea, which supports energy and cognitive function, and holy basil (tulsi), which has a calming effect on the nervous system, are common companions. Maca root is a peruvian adaptogen with some evidence for supporting hormonal balance and libido during perimenopause. These combinations can be useful, but they can also make it harder to know which ingredient is responsible for any benefit or side effect you experience. Starting with ashwagandha alone for six to eight weeks before adding other adaptogens makes it easier to assess its individual effect.
How to Know If It Is Working
The changes from ashwagandha are often gradual and can be subtle at first. Many women report noticing improved sleep before they notice a change in daytime stress levels. Others notice reduced reactivity to stressors before their general anxiety baseline changes. Tracking your mood, sleep quality, and anxiety levels consistently over time is the most reliable way to see whether the supplement is making a difference. Using an app like PeriPlan to log how you feel each day gives you a data trail that is more objective than memory alone. If after eight weeks of consistent use at an appropriate dose you notice no change in stress or sleep, it may not be the right tool for your particular symptom picture, and discussing other options with your doctor is a reasonable next step.
