You're in your early 40s, maybe late 30s, and something’s feeling different. Your jeans fit tighter than they did six months ago, and nothing you're doing seems to change it. You snap at your family over something small and then feel a wave of anxiety you can't shake. Your period showed up two weeks early, or two weeks late, or came with a ferocity you haven't experienced since your teens.
You Google your symptoms. The results say stress. Or thyroid. Your doctor pats you on the back and says, “All of this is normal when you get older!”
But what nobody told you, what shockingly few doctors bring up proactively, is that what you might be experiencing is perimenopause.
Let’s talk about how to handle it.
What Exactly Is Perimenopause?
Perimenopause is the transitional phase leading up to menopause, and it can begin anywhere from your late 30s to mid-40s. It lasts, on average, four to eight years, though for some women it stretches longer. Menopause itself is technically just one day: the 12-month anniversary of your last period. Everything before that is perimenopause, and it's where most of the action, and most of the symptoms actually happen.
Usually, when someone says they are “going through menopause,” what they really mean is that they are in perimenopause.
Despite affecting every woman who lives long enough to experience it, perimenopause remains one of the most under-discussed transitions in women's healthcare. Many women enter it without any warning, receive little guidance when they bring up their symptoms, and spend years attributing their experience to stress, depression, or simply "getting older." The result is a generation of women suffering unnecessarily, without the information or support they deserve.
That changes now.
What Perimenopause Actually Feels Like
Perimenopause symptoms are wide-ranging, often overlapping, and frequently mistaken for other conditions.
Hot flashes and night sweats are among the most recognized symptoms, sudden waves of heat, flushing, and sweating that can last seconds or minutes and happen at any time of day or night. Night sweats in particular disrupt sleep at a time when quality rest is already harder to come by.
Mood changes are extremely common and often distressing. Anxiety that feels new or worsened, irritability that seems disproportionate, low mood, emotional reactivity, and a general sense of feeling unlike “yourself” are all well-documented features of perimenopause.
Sleep disruption goes beyond night sweats. Many perimenopausal women experience difficulty falling asleep, staying asleep, or feel unrefreshed, regardless of how many hours they get. This compounds fatigue, mood issues, and cognitive symptoms significantly.
Brain fog, difficulty concentrating, slower recall, a sense that your thinking is less sharp, is reported by a majority of women in perimenopause and is one of the most unsettling symptoms because it affects daily functioning and identity.
Weight gain, particularly perimenopause belly and menopause belly, is one of the most frustrating aspects of this transition. Many women find that fat redistributes toward the abdomen even without changes in diet or exercise, and that weight loss approaches that previously worked simply stop working.
Vaginal dryness, discomfort, and low libido are among the most underreported symptoms because women are least likely to bring them up, and providers are least likely to ask. They are, however, among the most impactful on quality of life and relationships, and they are very addressable.
Irregular periods, heavier, lighter, closer together, or further apart, are often the earliest and most concrete signal that perimenopause has begun. Any significant change in your cycle in your late 30s or 40s warrants attention.
The Full Hormonal Picture
Here’s what’s happening to your hormones.
Progesterone Declines First
Most people think of estrogen as the primary hormone of perimenopause, but progesterone is typically the first to decline significantly, often beginning in the early 40s or even late 30s.
Progesterone is calming, sleep-promoting, and the natural counterbalance to estrogen. When it drops, the estrogen-progesterone ratio shifts, contributing to anxiety, sleep disruption, heavier periods, and what we know as estrogen dominance: not necessarily too much estrogen, but estrogen unbalanced by insufficient progesterone.
Estrogen Fluctuates, Then Falls
Estrogen doesn't decline in a straight line during perimenopause. It fluctuates, sometimes spiking well above normal before eventually tapering toward menopause. These erratic swings are responsible for many of the most disruptive symptoms: hot flashes, mood instability, brain fog, and sleep disruption. These all track closely with estrogen volatility.
Declining estrogen also affects bone density, cardiovascular health, cognitive function, vaginal tissue, and skin, which is why this transition has implications well beyond the years of active symptoms.
Testosterone Quietly Drops Too
Testosterone in women is often overlooked entirely, but it plays a meaningful role in libido, energy, motivation, strength, and cognitive sharpness. It declines gradually throughout the 30s and 40s, and its loss contributes to the low drive, fatigue, and "flat" feeling many perimenopausal women describe.
Cortisol and Insulin Resistance Rise
As ovarian hormone production becomes less reliable, the adrenal glands are called upon to pick up some of the hormonal slack, producing precursor hormones that can be converted to estrogen and other sex hormones. This increased demand taxes the adrenals, often driving cortisol dysregulation at a time when stress resilience is already compromised.
Simultaneously, declining estrogen reduces insulin sensitivity, making blood sugar harder to regulate and fat storage, particularly in the abdomen, more likely. This is a significant driver of perimenopause belly, and supplements for menopause weight gain become a topic of real interest for this reason. (For a deeper look at cortisol's role in abdominal fat, my post on cortisol belly covers the full mechanism.)
What Lifestyle Changes Actually Move the Needle
Before we get to supplements, it's worth being clear: no supplement outworks a foundation of supportive daily habits. The good news is that the lifestyle changes most beneficial for perimenopause are also deeply nourishing for overall health and longevity.
Stabilizing blood sugar is one of the highest-leverage changes you can make. Eating balanced meals with adequate protein, healthy fat, and fiber at regular intervals keeps insulin in check, reduces cortisol spikes, and helps manage weight and mood. Avoiding prolonged fasting, skipping meals, or relying on caffeine to get through the day is particularly important during this transition.

Prioritizing sleep as a non-negotiable, not a luxury, is essential. Sleep is when hormone regulation, metabolic repair, and emotional processing happen. Even moderate, consistent sleep deprivation significantly worsens every perimenopausal symptom.
Moving your body in ways that support rather than stress it matters more than ever. Strength training is particularly valuable in perimenopause. It helps preserve muscle mass, supports bone density, improves insulin sensitivity, and helps with body composition in ways that cardio alone cannot. Restorative movement like yoga and walking supports cortisol regulation and nervous system health.
Reducing alcohol is one of the most impactful and least discussed interventions. Alcohol disrupts sleep architecture, raises cortisol, impairs liver estrogen clearance, and worsens hot flashes. Many women find that even a modest reduction significantly improves their symptom picture.
Anti-inflammatory eating, centered on whole foods, colorful vegetables, quality protein, omega-3 rich fats, and minimal processed foods and sugar, directly supports hormonal metabolism, gut health, and the estrobolome (the gut bacteria colony responsible for estrogen clearance).
Supplements for Perimenopause: A Doctor’s Guide
With a strong lifestyle foundation in place, the right supplements can provide meaningful additional support. Here's an honest, evidence-informed walkthrough of the best vitamins and supplements for perimenopause.
MACA ROOT
Maybe you already know how much I love my maca. Maca is one of the most well-studied and traditionally used supplements for perimenopause, and for good reason.
It works not by introducing hormones into the body, but by supporting the HPA axis, the communication pathway between the brain and adrenal glands, to help the body modulate its own hormone production more effectively.
Studies have shown maca can reduce hot flash frequency and severity, support energy and mood, and help with libido. (1,2) It's particularly valuable during perimenopause because of the increased adrenal demand that comes with declining ovarian function.
MAGNESIUM
Magnesium is arguably the most important mineral for perimenopausal women, and it’s often something that’s low in the modern diet.
It supports sleep quality, reduces anxiety, helps regulate cortisol, supports progesterone synthesis, and plays a role in over 300 enzymatic processes in the body. Magnesium glycinate is the most bioavailable and gentle form for most women. Taking it in the evening supports sleep particularly well.
VITAMIN D3 & K2
Vitamin D functions more like a hormone than a vitamin, and its decline is associated with low mood, immune dysfunction, increased inflammation, and accelerated bone loss, all concerns during perimenopause. K2 is paired with D3 because it directs calcium to bones rather than soft tissue. Most perimenopausal women benefit from supplementation, particularly in northern latitudes or with limited sun exposure, and testing your levels is worthwhile.
B VITAMINS, ESPECIALLY B6 AND B12
B6 specifically supports progesterone production, helps the liver clear excess estrogen, and plays a direct role in serotonin and dopamine synthesis, which is why it can meaningfully support mood, PMS-like symptoms, and emotional regulation during perimenopause. B12 supports energy, neurological function, and cognitive clarity. A high-quality B complex that includes methylated forms (methylfolate, methylcobalamin) is ideal, particularly for women with MTHFR variants.
Your adrenals need B Vitamins to function properly, and adrenal support should be the cornerstone of any perimenopause or menopause supplement regimen!
OMEGA-3 FATTY ACIDS
Omega-3s, particularly EPA and DHA from fish or algae oil, are anti-inflammatory, support brain health and mood, help reduce hot flash frequency in some studies, and support cardiovascular health, which becomes increasingly important after menopause. Most women are significantly under-consuming omega-3s relative to omega-6s. A high-quality fish oil or algae-based omega-3 supplement is one of the most broadly beneficial additions a perimenopausal woman can make to your supplement stack.
ASHWAGANDHA
Ashwagandha is a well-researched adaptogenic herb that helps regulate the stress response, reduce cortisol, support thyroid function, and improve sleep quality. For perimenopausal women dealing with anxiety, fatigue, poor sleep, and adrenal stress, it can be a meaningful part of a supplementation strategy. It pairs particularly well with maca for comprehensive HPA axis support.
BIOIDENTICAL PROGESTRONE CREAM
For women experiencing significant sleep disruption, anxiety, heavy periods, or clear signs of progesterone deficiency, over-the-counter bioidentical progesterone cream is worth a conversation with your provider.
Unlike synthetic progestins, bioidentical progesterone is structurally identical to the progesterone your body produces. It's available without a prescription in low doses and may offer meaningful relief for some women, though individual response varies and professional guidance is valuable.
VAGINAL MOISTURIZERS & LUBRICANTS
Vaginal dryness and discomfort are among the most impactful and least addressed perimenopause symptoms. Non-hormonal vaginal moisturizers used regularly (not just during sex) help maintain tissue health and comfort.
Lubricants support sexual comfort. For women with more significant vaginal atrophy, localized vaginal estrogen, available by prescription and with a very low systemic absorption, is highly effective and considered safe even for many women who cannot use systemic HRT. This is a conversation worth having with your provider.
Other women respond better to topical DHEA, or a combination of DHEA and estrogen.
A Note on Hormone Replacement Therapy (HRT)
HRT deserves an honest, nuanced mention because the conversation around it has been significantly distorted by a now largely reinterpreted 2002 study that caused many women to avoid it out of fear, and many providers to stop offering it.
The current evidence suggests that for most healthy women under 60 or within 10 years of menopause onset, the benefits of HRT, relief from symptoms, protection of bone density, cardiovascular benefit when started early, cognitive support, and quality of life, outweigh the risks. The risk profile varies significantly based on the type of HRT (bioidentical vs. synthetic), the route of administration (transdermal vs. oral), and individual health history. (3-7)
HRT is not the right choice for every woman. But it is a legitimate, effective option that more women deserve to have a fully informed conversation about with a knowledgeable provider. If your symptoms are significantly impacting your quality of life, please don't let outdated fear keep you from exploring all of your options.
Perimenopause, Supplements, And Empowerment
Here's what I want you to take from all of this: perimenopause and menopause is a significant hormonal transition, one that deserves real information, real support, and real respect.
Yes, your symptoms are real, and yes, by embracing lifestyle changes and some supplements to help you along the way, things don’t have to be torturous. You can get your spark back.
Whether you begin with magnesium and maca, overhaul your morning routine, have a conversation with your provider about progesterone, or simply start by understanding for the first time what's actually happening in your body, every step forward matters.
