Best Supplements for Women's Health

Women's hormonal biology is more complex, more variable, and more underresearched than men's. This guide is built on what the evidence actually shows, across every major life stage.

Stress and Sleep

An honest starting point

Women's health supplements are one of the most aggressively marketed categories in the industry and one of the least rigorously evidenced. "Hormone balancing" is often used as a label on products with no clinical data to support the claim. This guide takes a different approach: every recommendation is grounded in published human research, the mechanisms are explained, and where evidence is limited, we say so.

Women's biology also differs from men's in ways that matter for supplement selection. Hormonal cycling creates monthly variation in nutrient requirements, stress sensitivity, and sleep architecture. Reproductive life stages (reproductive years, perimenopause, post-menopause) involve distinct hormonal environments that call for different approaches. This guide addresses each stage directly.

One correction worth making immediately: most adaptogens, including Tongkat Ali, Ashwagandha, and Shilajit, are marketed almost exclusively to men but have meaningful evidence for women as well. The hormonal mechanisms are different but the benefits are real. This guide includes them where the evidence supports their use for women.

Hormonal Foundation

Hormonal balance: what the science actually shows

Female hormonal health is regulated by a complex interplay of the HPO (hypothalamic-pituitary-ovarian) axis, the HPA (hypothalamic-pituitary-adrenal) stress axis, and thyroid function. These systems interact constantly. Chronic stress, via elevated cortisol, directly suppresses the HPO axis and can disrupt ovulation, worsen PMS symptoms, accelerate menstrual irregularity, and intensify perimenopausal symptoms.

This connection between stress hormones and reproductive hormones is why adaptogenic herbs frequently show benefits for women's hormonal health — not because they "balance hormones" in some undefined way, but because they reduce cortisol, which removes a primary source of HPO disruption.

01
Ashwagandha (KSM-66)
300–600mg / Evening
A 2021 randomised study specifically in women found that KSM-66 Ashwagandha significantly improved sexual function, arousal, satisfaction, and lubrication compared to placebo after 8 weeks. The mechanism is cortisol-mediated: high cortisol suppresses sex hormones across both sexes. The same trial also recorded significant improvements in mood and energy. The KSM-66 form (root extract standardised to 5% withanolides) is the most studied for these outcomes.
Evidence base is specifically in women, not only men — an important nuance missed by most supplement guides.
02
Tongkat Ali
200mg / Morning
Tongkat Ali is almost exclusively marketed to men, which obscures its genuine relevance to women. Its mechanisms include cortisol reduction, stress resilience improvement, and SHBG modulation — all of which apply to women's hormonal health. A 2014 study found that Tongkat Ali supplementation significantly improved testosterone levels, mood, energy, and wellbeing in women as well as men. Women have testosterone too, and its decline with age and stress contributes to low libido, fatigue, and reduced motivation in women just as it does in men.
Particularly relevant for women experiencing stress-related libido decline, low energy, or flat mood.
03
Magnesium Glycinate
300mg elemental / Evening
For women specifically, magnesium has strong evidence in two areas beyond general sleep and stress: PMS symptom reduction and menstrual migraine prevention. A 2000 study found magnesium supplementation significantly reduced PMS-related mood symptoms. Multiple studies have found magnesium glycinate effective at reducing menstrual migraine frequency. The underlying mechanism is prostaglandin regulation — magnesium modulates the inflammatory prostaglandins responsible for dysmenorrhea (painful periods) and migraine.
For PMS and cycle-related symptoms, consistency across the full month matters more than timing around the cycle.
On perimenopause and menopause

The transition through perimenopause (typically 40 to 52) involves significant declines in oestrogen and progesterone, with corresponding changes in sleep architecture, stress sensitivity, cognitive function, and bone density. The supplements below address the specific biological shifts of this period. None of them replicate oestrogen. They support the systems that oestrogen withdrawal most affects: sleep quality, cortisol regulation, bone mineralisation, and neurological protection.

Stress

Supplements for stress and cortisol

Women's cortisol response to stress is physiologically different from men's. Research suggests women show greater cortisol reactivity to interpersonal and social stressors, and the recovery period after acute stress is often slower. This makes cortisol management particularly important for women's hormonal health, sleep quality, and immune function.

01
Ashwagandha (KSM-66)
300–600mg / Evening
The strongest adaptogen evidence base for cortisol reduction (27.9% reduction in the Chandrasekhar 2012 trial). For women with stress-driven hormonal disruption, anxiety, or sleep problems, ashwagandha is typically the first recommendation. The KSM-66 form specifically has studies in women covering sexual health, mood, and cognitive function — not just stress. Evening dosing aligns with its calming mechanism.
02
Reishi Mushroom
500–1,000mg / Evening
Reishi's triterpenoids modulate the HPA stress axis and produce calming via GABA-A receptor interaction. For women dealing with stress-driven immune dysregulation (a common pattern in women with autoimmune tendencies), Reishi's immunomodulatory beta-glucans add a dimension of benefit that goes beyond stress alone. It is one of the few compounds that is simultaneously calming, immune-supportive, and anti-inflammatory.
03
L-Theanine
200mg / As needed
The most effective acute stress management supplement available. L-Theanine increases alpha brainwave activity within 30 to 60 minutes, producing calm alertness without sedation. Clinical evidence shows benefits for stress response, sleep onset, and sustained attention. Women dealing with anxiety-driven sleep difficulty often use it in the evening; those managing daytime cognitive stress pair it with morning coffee. No dependency or tolerance issues at standard doses.
Sleep

Supplements for sleep

Women report insomnia and poor sleep quality at significantly higher rates than men throughout adult life, with particular peaks during the premenstrual phase and perimenopause. The hormonal mechanisms behind this are understood: progesterone has GABAergic activity (calming), and its cyclical decline in the luteal phase and more permanent decline in perimenopause directly disrupts sleep architecture.

01
Magnesium Glycinate
300mg elemental / Evening
For women, Magnesium Glycinate targets sleep through two pathways simultaneously: GABA receptor activation (replacing some of the calming effect that declining progesterone previously provided) and cortisol reduction (removing the HPA-driven sleep interference). The glycine component independently improves sleep quality scores and reduces fatigue on waking. This makes it particularly well-suited to the sleep disruption pattern most common in premenstrual and perimenopausal women.
02
Reishi Mushroom
500mg / 1 to 2 hrs before sleep
Reishi's GABA-A modulation makes it a valuable addition to the evening protocol for women whose sleep is disrupted by stress, anxiety, or the hormonal fluctuations of the menstrual cycle. It works gradually — most users notice improved sleep quality after 2 to 4 weeks of consistent evening use. Pairs well with Magnesium Glycinate, as both are calming, non-sedating, and safe for long-term daily use.
On melatonin for women: Standard melatonin doses (3 to 10mg) are pharmacologically excessive. A 0.5mg dose is often sufficient for sleep onset support, particularly for circadian disruption (shift work, travel). For women with hormone-related sleep disruption, the root cause (cortisol, progesterone decline, anxiety) is better addressed directly. Magnesium Glycinate and Reishi address these causes rather than simply signalling sleep time.
Energy and Cognition

Supplements for energy

Energy problems in women are often attributed to iron deficiency anaemia, which is a real and important consideration (particularly for menstruating women with heavy periods). But the most common cause of persistent fatigue in women without anaemia is mitochondrial inefficiency driven by chronic stress, poor sleep, and magnesium depletion — all addressable through supplementation.

01
Shilajit
250–500mg / Morning
Shilajit's fulvic acid complex is one of the most effective mitochondrial support compounds available and it is relevant to women for the same reason it's relevant to men: it targets the energy production machinery itself, not the nervous system. For women experiencing the kind of fatigue that doesn't improve with rest, this mechanism is often more relevant than more sleep or more caffeine. The 84+ ionic minerals it provides also correct deficiencies common in women eating calorie-restricted diets or experiencing heavy periods.
02
Cordyceps
500–1,000mg / Morning
Cordyceps improves oxygen utilisation efficiency and cellular ATP availability — energy benefits that are completely sex-neutral. Women who train or who need sustained output through demanding days find it as effective as men do. Its testosterone-supporting effect in women is also relevant: women's free testosterone contributes to energy, libido, and motivation, and Cordyceps' Leydig cell stimulation activity (present in both sexes' adrenal production of testosterone) supports this.

Cognitive health and brain protection

Women have a statistically higher lifetime risk of Alzheimer's disease than men, partly attributed to the neuroprotective role of oestrogen and its decline in menopause. This makes neurological support supplements particularly relevant for women in their 40s and beyond, not as treatment but as preventive maintenance.

01
Lion's Mane
500–1,000mg / Morning
Lion's Mane stimulates Nerve Growth Factor, the protein responsible for neuron health and connectivity. The 2009 Mori RCT included both men and women, showing equal benefit. The 2010 study specifically in menopausal women showed significant improvements in anxiety, depression, and cognitive concentration. For women in perimenopause or post-menopause concerned about "brain fog" and memory changes, Lion's Mane addresses these directly via the NGF pathway rather than treating them as an inevitability.
02
Magnesium L-Threonate
1,500–2,000mg / Morning
Brain magnesium supports synaptic plasticity — the mechanism by which neurons strengthen connections during learning and memory formation. Oestrogen normally supports brain magnesium transport, so its decline in menopause creates a gap that L-Threonate can partially address. The 12-week RCT showing improvements in working memory and executive function included both sexes. For women in their 40s and beyond, this is the most targeted cognitive supplement available.
Recommendations by life stage
Select your stage for a prioritised starting protocol.
01
Magnesium Glycinate
The highest single-supplement impact for most women in this decade. Addresses sleep quality, PMS symptoms, stress response, and cycle-related migraines.
300mg / Eve
02
Ashwagandha (KSM-66)
For stress-driven hormonal disruption, anxiety, or irregular cycles. Evidence specifically in women for mood, libido, and reproductive health.
300mg / Eve
03
Lion's Mane
Cognitive maintenance and mood support via NGF. The 2020 study in healthy young adults showed anxiety and depression reduction after 4 weeks.
500mg / AM
01
Ashwagandha + Reishi
The dual cortisol and GABA-modulating combination. Most effective for the sleep disruption and anxiety intensification common in perimenopause.
Eve
02
Lion's Mane (higher dose)
Brain fog and cognitive changes accelerate in perimenopause. NGF support becomes more valuable as oestrogen-driven neuroprotection declines.
750mg / AM
03
Magnesium Glycinate + L-Threonate
Evening glycinate for sleep; morning L-Threonate for brain magnesium. This pairing directly addresses the two most common cognitive complaints in this stage.
Split AM/Eve
04
Shilajit
Mitochondrial energy support and mineral bioavailability. Particularly relevant as energy levels become less predictable during hormonal transition.
250mg / AM
01
Lion's Mane (1,000mg)
Neuroprotection and cognitive maintenance become primary priorities. Higher dose warranted as preventive maintenance for brain health.
1,000mg / AM
02
Magnesium L-Threonate
Brain magnesium for synaptic health. Memory and cognitive clarity are the primary quality-of-life concerns for many women post-menopause.
1,500mg / AM
03
Reishi
Immune resilience, longevity support, and sleep quality. Post-menopausal women face elevated cardiovascular and immune risk; Reishi addresses both.
500mg / Eve
04
Tongkat Ali
Supports residual testosterone levels critical for energy, bone density, libido, and mood in post-menopausal women.
200mg / AM
01
Magnesium Glycinate (daily, not just pre-period)
Multiple RCTs showing PMS mood, cramping, and migraine improvement. Must be taken continuously — the tissue stores that matter build over weeks, not days.
300mg / Daily
02
Ashwagandha
Cortisol dysregulation amplifies PMS symptoms significantly. Ashwagandha's consistent cortisol modulation reduces the hormonal sensitivity that makes PMS severe.
300mg / Eve
03
L-Theanine
For the anxiety, irritability, and focus disruption in the luteal phase. Safe, effective, non-hormonal. Can be taken daily or as-needed during the 1 to 2 weeks before menstruation.
200mg / As needed
FAQ

Questions, answered honestly

Magnesium, Lion's Mane, Reishi, and Cordyceps have no known interactions with hormonal contraception. Ashwagandha and Tongkat Ali both influence cortisol and (mildly) sex hormone levels. Theoretically, adaptogens that modulate the HPA axis could interact with exogenous hormones, though no direct interaction studies in women on hormonal contraception exist for these compounds. As a precaution, if you're on hormonal contraception for medical reasons beyond cycle control, consult your prescribing doctor before starting adaptogens. For healthy women using contraception without underlying hormonal conditions, the risk is considered low.
PCOS involves elevated androgens, insulin resistance, and HPA axis dysregulation — all of which adaptogens address in complementary ways. Ashwagandha's cortisol modulation can reduce HPA-driven androgen production. Magnesium improves insulin sensitivity, a key factor in PCOS. Lion's Mane addresses the mood and cognitive symptoms. Tongkat Ali is less appropriate here given its testosterone-supporting mechanism in an already high-androgen environment. Always work with your gynaecologist for PCOS management — supplements are adjuncts, not primary treatment.
As a precautionary position, we do not recommend adaptogens (Ashwagandha, Tongkat Ali, Reishi, Shilajit) during pregnancy due to insufficient safety data in pregnant women. Magnesium supplementation in the glycinate or citrate form is generally considered safe during pregnancy and is often recommended by midwives for leg cramps — confirm with your obstetric care team. During breastfeeding, the same caution applies to adaptogens; magnesium is typically considered safe. Always consult your healthcare provider for any supplementation during pregnancy or lactation.
Most clinical trials use fixed doses regardless of sex or bodyweight. For adaptogens, the evidence generally supports the same dose ranges for women as men. Some practitioners suggest starting at the lower end of the recommended range (e.g., 300mg Ashwagandha rather than 600mg) and adjusting based on response — this is sensible general supplementation practice rather than a sex-specific requirement. Magnesium RDA is slightly lower for women than men (310mg vs 400mg), though the supplemental doses used in clinical trials are similar.
