Perimenopause Support
About this protocol
Where to start
Start with magnesium glycinate. It addresses sleep disruption, anxiety surges, PMS-like symptoms, and muscle tension all at once. The single most-leveraged supplement in this phase.
Add a methylated B-complex for energy, mood, and the methylation support that becomes more relevant in this hormonal window.
Chasteberry (Vitex agnus-castus) has the best evidence for cycle regularity in perimenopause — particularly useful if luteal-phase mood symptoms have intensified or cycles have become irregular. Effect builds over 2-3 cycles.
Omega-3 EPA/DHA for mood stability and the cardiovascular foundation that matters increasingly through this decade.
Maca is the most speculative in this stack — small trials suggest mood and energy benefits in perimenopausal women but the literature is thin. Worth an 8-12 week trial if energy is a dominant symptom.
If your symptoms are significantly disrupting your life, see a perimenopause-aware gynecologist. Many women benefit from cyclic progesterone, low-dose oral contraceptives, or early-window MHT — and these can be combined with the supplement stack.
5 nutrients
Start here
Strongest evidence — the foundation of the stack.
Magnesium Glycinate
300-400 mg elemental, before bedMagnesium is the single most-leveraged supplement in perimenopause — it addresses sleep disruption, anxiety, mood swings, muscle tension, and PMS-like symptoms simultaneously. Multiple trials in women across the reproductive lifespan find consistent benefit. The glycinate form is gentle on the GI tract and pairs with the calming glycine carrier.[1, 2, 3]
Methylated B-Complex
1 capsule daily, with breakfastB-vitamins are cofactors in estrogen metabolism, neurotransmitter synthesis, and energy production — all of which are stressed during the perimenopausal transition. Methylated forms (methylfolate, methylcobalamin) bypass the MTHFR enzyme step, useful for the 30-40% of women with MTHFR variants. Supports energy, mood, and the cognitive symptoms common in this phase.[4, 5]
Add if needed
Add these only if the foundation isn't enough.
Chasteberry (Vitex agnus-castus)
20-40 mg standardized extract, dailyChasteberry has the strongest botanical evidence for cycle-related symptoms in perimenopause — irregular cycles, intensified PMS, breast tenderness, mood swings. Mechanism is dopaminergic — modulation of prolactin levels in the luteal phase. A systematic review of randomized trials found consistent benefit across 2-3 cycles. Use a standardized extract.[6, 7, 8]
Omega-3 (EPA/DHA)
1-2 g combined EPA+DHA, with breakfastOmega-3 supplementation supports mood stability and the cardiovascular foundation that becomes increasingly important through the 40s. Trial evidence supports modest effects on perimenopausal mood symptoms specifically. The long-term cardiovascular protection is well-established.[9, 10, 11]
Experimental
Emerging evidence — try last, only if curious.
Maca (Lepidium meyenii)
1.5-3 g powder daily, with breakfastMaca is an Andean adaptogen with emerging trial evidence for perimenopausal mood, energy, and libido. Sample sizes are small and the literature needs replication. Treat as the most speculative item in the stack — worth a structured 8-12 week trial if energy and libido are dominant symptoms.[12, 13, 14]
Warnings
Lifestyle improvements
Track your cycles relentlessly
A cycle-tracking app or simple calendar tells you whether you're in perimenopause and whether the stack is helping. Note cycle length, flow heaviness, premenstrual symptoms, sleep, and mood. Two years of data is more useful than a year of memory.
See a perimenopause-aware provider
Many primary care doctors and OBs are still under-trained on perimenopause. Look for a provider certified by the Menopause Society (formerly NAMS). Modern options include cyclic progesterone for sleep and luteal mood, low-dose oral contraceptives for cycle regulation, and early-window MHT.
Resistance training is critical now, not later
Bone density loss accelerates in perimenopause, not just at menopause. 2-3 heavy strength sessions per week (squats, deadlifts, presses, pulls) is the most effective intervention available — more impactful than calcium alone.
Protein adequacy
Aim for 1.2-1.6 g/kg body weight daily. Most women under-consume protein, and the demands of muscle preservation rise in the 40s.
Sleep deserves explicit work
Sleep disruption is one of the earliest perimenopausal symptoms. Magnesium and the Better Sleep protocol stack naturally on top of this one.
Limit alcohol
Perimenopausal night sweats are amplified by alcohol. Many women find a multi-week alcohol-free trial dramatically improves sleep, mood, and hot flashes.
Reduce caffeine in the afternoon
Caffeine half-life lengthens with age. The 2 PM coffee that didn't bother you in your 30s may now keep you up at midnight.
Get baseline labs
Track 25-OH vitamin D, ferritin, lipid panel, ApoB, HbA1c, hsCRP, TSH, and FSH (FSH is variable in perimenopause, so a single value is less informative than the symptom pattern).

Menopause Support
hormones
The menopausal transition disrupts more than just reproductive hormones — estradiol decline affects sleep, mood, bone density, cardiovascular risk, cognition, and skin. Hormone replacement therapy (HRT/MHT) remains the most effective intervention for moderate-to-severe symptoms and the long-term benefits for bone and cardiovascular health are well-established when started within the first ten years post-menopause. Supplements are first-line for women with mild symptoms, contraindications to HRT, or as a complement to HRT for symptom subsets. Black cohosh has the strongest evidence for vasomotor symptoms (hot flashes); magnesium and omega-3 support sleep, mood, and bone health.
PMS Support
hormones
Premenstrual syndrome affects up to 75% of menstruating women in some form. The supplement literature is unusually solid here — magnesium, B6, calcium, and chasteberry each have multiple randomized trials supporting their use for the physical and emotional symptoms of PMS. Effect sizes are real but modest, and the stack works best when taken consistently across the cycle rather than only in the luteal phase. Severe PMS or PMDD warrants a conversation with your doctor — supplements are first-line for mild-to-moderate symptoms, not a substitute for proper care in severe cases.
PCOS Support
hormones
Polycystic ovary syndrome (PCOS) affects roughly 10% of reproductive-age women and is one of the most under-diagnosed endocrine conditions. The core pathology involves insulin resistance, androgen excess, and ovulatory dysfunction — and the supplement category here has unusually good evidence. Myo-inositol is the gold-standard supplemental intervention for PCOS, with effects approaching metformin for restoring ovulation and reducing hyperandrogenism. NAC has small but consistent evidence for ovulation and insulin sensitivity. Vitamin D, magnesium, and berberine support the underlying insulin-resistance pathway. This stack complements lifestyle (the most impactful intervention) and medical therapy when needed. It does NOT replace metformin, GLP-1 agonists, or ovulation induction in women actively trying to conceive — but it can reduce reliance on them in milder cases.
Women's Libido & Desire
hormones
Female sexual desire is multifactorial — hormonal status (estrogen, testosterone, progesterone, thyroid), relationship dynamics, mental health, stress, sleep, medication side effects (especially SSRIs and oral contraceptives), and physical comfort all matter, often more than any single supplement. Hypoactive Sexual Desire Disorder (HSDD) affects roughly 1 in 10 women, and the most common drivers in our culture are chronic stress, sleep debt, medication side effects, and relational rather than biochemical factors. Supplements address one slice of the picture and are not a substitute for proper medical evaluation when desire loss is severe or distressing. That said, a handful of supplements have real trial evidence in women specifically — not extrapolated from male data. Maca has the most consistent evidence for libido and desire in both pre- and postmenopausal women, with effects that appear independent of hormonal change. Ashwagandha shows benefit on female sexual function through stress modulation. Vitamin D and zinc are deficiency-correction nutrients — if you''re low, repletion helps; if you''re replete, additional supplementation does nothing. L-citrulline has indirect support for genital blood flow. Most women''s libido issues are NOT supplement-deficiency problems, but for the subset where they are, this stack is well-targeted.
Adrenal / Burnout Recovery
hormones
"Adrenal fatigue" is not a recognized medical condition — the adrenals don''t actually get tired. What IS real is occupational burnout (recognized by the WHO) and HPA-axis dysregulation: chronic stress flattens the normal diurnal cortisol curve, producing morning fatigue, "tired but wired" evenings, and emotional exhaustion. This pattern is distinct from depression or anxiety, though it overlaps with both. The supplement stack here targets HPA-axis modulation (ashwagandha, rhodiola), cortisol-utilization cofactors (vitamin C, B-complex), and acute cortisol blunting (phosphatidylserine). It does NOT replace addressing the upstream cause — chronic occupational, financial, or relationship stress — which is the only durable fix. Supplements support recovery; they don''t enable continued burnout. If you''re experiencing significant emotional exhaustion, cynicism, reduced sense of accomplishment, sleep disruption, and physical symptoms — those are clinical burnout signs, and addressing them often requires more than supplements (workload reduction, therapy, sometimes time away from work).
Sexual Health for Men
hormones
Male sexual function is downstream of vascular health, hormonal balance, nervous system regulation, and psychological state. Most "natural Viagra" supplements are over-marketed and under-evidenced, but a handful of compounds have real trial backing. L-citrulline is the most-evidenced supplement for erectile function in mild-to-moderate ED — it works through the same nitric oxide pathway as PDE5 inhibitors. Panax ginseng has the second-strongest evidence and works through somewhat different mechanisms. Zinc supports testosterone synthesis when deficient. Maca has small trial evidence for libido specifically. This stack is for mild-to-moderate symptoms and for healthy men optimizing function — not a substitute for proper medical workup of new-onset erectile dysfunction, which can be an early sign of cardiovascular disease.
