Adaptogens for Women (ashwagandha, rhodiola, maca): which to choose and when

The u Bucha store currently has 31 products for sale that declare ashwagandha, rhodiola, or maca in their specifications. Among them, there are six single-ingredient preparations, while the rest are blends where the raw material of interest is combined with four others. This ratio has practical implications: with one raw material, you know what worked, while with five, you know nothing. The quality of evidence is unevenly distributed among these three plants, and the difference is greater than suggested by sales descriptions. Below you will find what clinical studies have really shown for each of them, a comparison of real items from the store, and the cost per day of use, which allows for a comparison of powder, capsules, and drops.

KEY INFORMATION
• Ashwagandha reduced cortisol levels by 27.9% after 60 days (Chandrasekhar et al., IJPM, 2012).
• Rhodiola has no clinical trials on women in the perimenopausal period.
• Maca improved symptom scoring without changing estradiol and FSH levels (Brooks et al., Menopause, 2008).
• Rhodiola cannot be bought separately in the store.

Which adaptogen to choose for stress, and which for fatigue?

For chronic stress with sleep disturbances, the first choice is ashwagandha; for fatigue and decreased attention, it's rhodiola; and for reduced libido after menopause, maca. This division comes from what has been measured: cortisol and sleep parameters for ashwagandha, burnout and attention for rhodiola, and climacteric symptom scores for maca.

The mechanisms also differ. Ashwagandha acts on the hypothalamic-pituitary-adrenal axis, which is the same system that maintains elevated cortisol levels during prolonged stress. Rhodiola is described as a monoaminergic substance, affecting the availability of serotonin and dopamine, which explains why its effects are seen in attention tests rather than in sleep scales. Maca does not belong to adaptogens in the strict sense, as it does not modify the stress response, and its action has been described at the symptom level, not at the hormonal level.

Our observations from conversations in the store: the most common mistake is reaching for a blend of four ingredients on the first try. A woman who feels an improvement in her sleep after six weeks doesn't know whether it's due to ashwagandha, lemon balm, or melatonin from the same bottle. The reverse order is cheaper and more educational: one ingredient, eight weeks, notes every week. Before attributing fatigue to stress, it's worth ruling out a simpler cause: in menstruating women, it can be low ferritin with normal morphology, which we discussed in the text about iron for fatigue in women without anemia.

What does ashwagandha do to cortisol and sleep?

It is the only one of the three substances with a repeatable effect on a hard laboratory parameter. In the study Chandrasekhar i wsp. (Indian Journal of Psychological Medicine, 2012) 64 individuals with chronic stress took 300 mg of root extract twice daily for 60 days. Serum cortisol levels decreased by 27.9% compared to placebo, with p = 0.0006.

It is worth immediately noting the limitation of this result: the trial included both women and men, and the authors did not analyze the results separately by gender. Therefore, there is no study showing a specific cortisol effect of ashwagandha for women. However, there is a physiological rationale, as chronically elevated cortisol inhibits the secretion of gonadotropin-releasing hormone, and thus LH and FSH, which in some women translates to irregular cycles.

Sen zmierzono osobno. W pracy Langade i wsp. (Cureus, 2019) Sixty patients with insomnia and anxiety received 300 mg of extract twice daily for 10 weeks. Sleep efficiency increased from 75.6% to 83.5%, while in the placebo group it rose from 75.1% to 79.7%. The time taken to fall asleep significantly decreased compared to placebo with p = 0.019. This result comes from a group diagnosed with insomnia, not from healthy individuals who want to sleep a little better. We compiled the ingredients outside of this trio, for which cortisol was measured directly, in the text about suplementach na stres i kortyzol.

What do we really know about rhodiola in women?

Nothing is known specifically about women. None of the clinical trials of rhodiola have been conducted on women in the perimenopausal period or reported results by gender. Everything you read about rhodiola for menopausal symptoms is a transfer of results from mixed groups.

The results themselves are more robust than this gap suggests. Olsson i wsp. (Planta Medica, 2009) They administered 576 mg of SHR-5 extract daily for 28 days to 60 individuals diagnosed with fatigue syndrome. A significant advantage over placebo was observed in the Pines burnout scale and in several attention indicators in the CCPT II test, as well as in the cortisol response upon awakening. Improvement in quality of life and mood appeared in both groups, including the placebo group, so it should not be attributed to the plant.

Two smaller studies complement the picture. Bystritsky i wsp. (Journal of Alternative and Complementary Medicine, 2008) This is a pilot study without a control group: ten individuals with generalized anxiety disorder, 340 mg daily for 10 weeks, showing a significant decrease in the HARS scale with p = 0.01. Meanwhile, Darbinyan i wsp. (Nordic Journal of Psychiatry, 2007) they administered 340 or 680 mg daily for six weeks to individuals with mild to moderate depression, achieving improvement in the HAMD scale at both doses. You can find more about the substance itself in the post Rhodiola rosea: properties for stress and fatigue.

Does maca affect libido without influencing estrogen?

Yes, and this is the best-documented feature of this plant. In the study Brooks i wsp. (Menopause, 2008) fourteen postmenopausal women took 3.5 g of powdered maca daily for six weeks in an alternating regimen with placebo. Estradiol, FSH, LH, and SHBG levels did not change at any measurement point.

However, the scores in the Greene climacteric scale changed. The decrease concerned the anxiety and depression subscales as well as sexual dysfunction, compared to placebo and baseline values. Additionally, the authors examined maca extracts in a yeast reporter assay and found no estrogenic or androgenic activity. This is important in hormone-dependent breast cancer, where soy isoflavones raise concerns, and maca does not have this mechanism.

However, the scale of evidence is small, and this must be stated plainly. A systematic review Shin i wsp. (BMC Complementary and Alternative Medicine, 2010) included four randomized trials of maca and sexual function. Two indicated benefits, in postmenopausal women and healthy men, one in cyclists showed no effect, and the authors summarized the overall evidence as limited. Fourteen participants is too few to speak of a resolution.

Which products containing these three substances does the store u Bucha have?

There are 31 items for sale that declare at least one of these substances in their specifications, but rhodiola itself cannot be purchased separately: it is only available as an ingredient in blends. The following list includes items where the substance in question is mentioned with the amount in the daily portion.

The order in the table is determined by the cost per day of use, from the lowest. Prices are from the u Bucha store, as of August 8, 2026. You can find the full offer in the category supplements.

How much does a day of use cost in each form?

The range is thirty-three times: from 0.12 zł for a portion measured from powder to 3.97 zł for two capsules of oil macerate. The price of the packaging does not show this, as a bottle for 99 zł lasts for 26 days, while tablets for 20.99 zł last a full 30.

Three conversions require commentary. The loose powder came out the cheapest, as the portion was assumed to be 200 mg, which corresponds to the limit of 10 mg of withanolides indicated by the Dietary Supplements Team and referenced on the product card. The Aura Care bottles were calculated from the declared approximately 400 drops and the upper limit of 15 drops per day. Two items from Cosma Pure Herbs were left without results because the manufacturer does not provide the portion size for the liquid form, and guessing it would yield a number pretending to be precise.

The practical conclusion is uncomfortable for the more expensive shelves: with ashwagandha alone, the price difference per day between a tablet for 0.70 zł and a macerate for 3.97 zł is not supported by research, as both clinical trials described above were conducted on a regular root extract, not on an oil macerate.

Who should avoid these raw materials?

Pregnancy and lactation exclude ashwagandha without discussion. The product cards for loose products in the u Bucha store contain this information directly, and for maca and rhodiola, there are no safety studies involving pregnant women, so the same caution applies, just for a different reason: it is unknown, and it is unknown that it is harmful.

The second group is thyroid diseases. Ashwagandha is sometimes described as a raw material that increases levels of triiodothyronine and thyroxine, which in treated hypothyroidism poses a risk of overdosing on levothyroxine therapy. Hashimoto's disease is diagnosed much more often in women, so this caution applies to a large portion of female readers. The decision to combine is made by an endocrinologist after checking TSH.

Polycystic ovary syndrome and endometriosis require a conversation with a gynecologist, but with an honest caveat: there are no clinical trials of any of these three raw materials in these diagnoses. Regarding endometriosis, the only strong argument concerns maca, and it is a negative argument, namely the lack of estrogenic activity demonstrated by Brooks et al. The rest is mechanistic reasoning, not a study result.

The third area is medications. Rhodiola affects serotoninergic transmission, so combining it with SSRI or SNRI medications requires the approval of the attending physician. In hormonal replacement therapy and contraception, no clinically significant interactions with any of the three raw materials have been described, which does not exempt one from informing the gynecologist about supplementation.

How to structure the first eight weeks?

One raw material at a time, eight weeks, notes every week. This scheme directly results from the duration of the studies: effects were measured after 28 days for rhodiola, after six weeks for maca, and after 60 days for ashwagandha. A shorter trial will not provide answers, and a longer one without notes will not either.

The choice of starting point follows the dominant symptom. In cases of chronic stress with poor sleep, start with ashwagandha at a dose of 300 to 600 mg of extract daily, taken in the evening. For decreased energy and attention without sleep disturbances, choose rhodiola, 200 to 400 mg in the morning, remembering that you will only find it in a mixture in the store. For reduced libido after menopause, use maca, aiming for 3.5 g daily, which is the dose from the study by Brooks et al.

The notes should include four numbers weekly: the time of falling asleep, the number of nighttime awakenings, an energy rating on a scale from one to ten, and the length of the cycle. After eight weeks, you either see a difference in these records, or you don’t, and there’s no reason to extend. Only then consider adding a second raw material, and again one at a time. The reverse order, starting with a mixture of four plants, costs 99 zł per month and does not answer any questions.

Frequently Asked Questions

Which of these three raw materials has the strongest evidence?

Ashwagandha. The study by Chandrasekhar et al. (Indian Journal of Psychological Medicine, 2012) included 64 individuals with chronic stress and showed a decrease in serum cortisol levels by 27.9% with p = 0.0006. Rhodiola has smaller trials with mixed results, while maca is mainly based on one study involving fourteen women.

Does rhodiola help with menopause symptoms?

It is unknown, as no one has checked this in a study involving women in the perimenopausal period. Existing trials concern fatigue syndrome (Olsson et al., 2009), generalized anxiety disorder, and mild depression, in mixed-gender groups. Transferring these results to menopause is an assumption, not a conclusion from the data.

Does maca raise estrogen levels?

No. In the study by Brooks et al. (Menopause, 2008) involving fourteen postmenopausal women taking 3.5 g of maca daily, there were no changes in estradiol, FSH, LH, or SHBG levels. Yeast tests showed no estrogenic or androgenic activity of the extracts. The improvement concerned symptom scoring, not hormones.

Are adaptogens safe to use during pregnancy?

Not for ashwagandha. The product information sheets in the u Bucha store explicitly exclude use by pregnant and breastfeeding women. For maca and rhodiola, there is no safety data from studies involving pregnant women, so the same caution and decision by the attending physician applies.

Can ashwagandha be combined with levothyroxine?

Not without the supervision of an endocrinologist. Ashwagandha is sometimes described as a raw material that raises thyroid hormone levels, and in the case of treated hypothyroidism, this poses a risk of overdosing on therapy. Hashimoto's disease mainly affects women, so this caution applies to a significant portion of the readers of this text.

How long does it take before I see an effect?

The studies measured effects after 28 days for rhodiola, after six weeks for maca, and after 60 days for ashwagandha. Accept eight weeks as the minimum evaluation period for one raw material and do not add a second during this time, as you will lose the ability to attribute changes to a specific plant.
