Functional Medicine · Hormonal Health
Evidence-informed writing on hormones, energy, and performance — for women who don't have time to feel this tired.
Hormones · Estrogen
Estrogen isn't just a reproductive hormone. New 2024–2026 research shows how it shapes your brain, blood vessels, gut, liver, muscles, joints, immune system, and bladder.
Perimenopause · Motivation
If you used to be the one who got things done and now can't make yourself start, estradiol and dopamine may be why. What causes it, what else to rule out, and what helps.
Perimenopause · Mood
Snapping at people you love over things that never used to bother you? Why estradiol swings, stress, and broken sleep drive perimenopause irritability, and what helps.
Perimenopause · Brain Health
Losing words and your train of thought in your 40s? Research shows perimenopause brain fog is real and usually temporary. How to tell it apart from something more serious.
Hormone Therapy · FDA
The FDA removed breast cancer, heart disease, and dementia language from the boxed warning on menopause hormone therapy. What changed, what didn't, and what it means for you.
PCOS · Root Causes
PCOS was renamed polyendocrine metabolic ovarian syndrome (PMOS) in 2026. What the new name says about the real drivers: insulin resistance, androgens, inflammation, and stress. Plus the symptoms and what helps.
PCOS · Testing
You don't need cysts on an ultrasound to have PCOS. How PCOS (now PMOS) is diagnosed under the 2023 guideline, which labs to ask for, when an AMH blood test can replace the ultrasound, and what has to be ruled out first.
Cycles · Mood
If the week before your period feels like a different person takes over, it may be PMDD, not PMS. How PMDD is diagnosed, why it isn't a hormone imbalance, and what the research shows on SSRIs, the pill, calcium, and more.
Cycles · Pelvic Pain
Period pain that keeps you home isn't something to push through. How to tell normal cramps from endometriosis or adenomyosis, why diagnosis takes years, why you no longer need surgery to start treatment, and what helps.
Cycles · Root Causes
Missed, late, or unpredictable periods in your 20s and 30s are usually a sign, not a diagnosis. What counts as irregular, the common causes from PCOS and thyroid to under-fueling, and the labs that find the answer.
Thyroid · Autoimmunity
Positive TPO antibodies but a normal TSH? What that means, how often it turns into hypothyroidism, why you can still feel unwell, and what the research shows on selenium, gluten, and monitoring.
Stress · Cortisol
Your adrenals aren't worn out, but your stress system may be out of rhythm. What the research says about adrenal fatigue, what HPA axis dysfunction is, how cortisol is tested, why "adrenal support" supplements can be risky, and what helps.
Gut Health · Testing
What an IgG food sensitivity test actually measures, why allergy societies say it can't diagnose intolerance, what the one randomized trial found, and how to use the results without ending up on a needlessly narrow diet.
Gut Health · Inflammation
Leaky gut is real, but it's been oversold. What intestinal permeability is, what makes it worse, why zonulin tests are unreliable, and what actually helps the gut lining.
Gut Health · SIBO
Bloating that builds through the day may be SIBO. What small intestinal bacterial overgrowth is, who gets it, how breath testing works, what methane means, and how it's treated.
Gut Health · Hormones
Your gut bacteria help decide how much estrogen stays in circulation. What the estrobolome is, how beta-glucuronidase works, and why gut health matters for estrogen balance in your 40s and beyond.
Gut Health · Menopause
Menopause changes the gut microbiome, and those changes are linked to heart and metabolic health. What the research shows, why digestion shifts in your 40s and 50s, and what supports your gut through the transition.
Gut Health · Testing
What a comprehensive stool test measures, which markers have solid evidence behind them, which are still exploratory, and when stool testing is worth doing for bloating and ongoing digestive symptoms.
Hormones · Progesterone
Progesterone is often the first hormone to drop in perimenopause. New research shows how it shapes your sleep, mood, anxiety, bones, breasts, and blood vessels.
Perimenopause · Leadership
Brain fog, broken sleep, and a shorter fuse at work may not be burnout. What the research shows about perimenopause and performance in high-achieving women, and what helps.
Perimenopause · Supplements
Which perimenopause supplements have real research behind them? An evidence-based look at ashwagandha, saffron, creatine, S-equol, black cohosh, and more.
Perimenopause · Cycles
Flooding, longer periods, or cycles that come every two weeks? Here's why perimenopause changes your period, what's normal, the red flags, and what helps.
Perimenopause · Bone Health
The fastest bone loss of a woman's life starts about a year before her final period. Here's when it happens, who's at risk, and what actually protects your bones.
Hormones · Testosterone
The FDA just held its first public workshop on testosterone for menopausal women, with prescriptions up 146% and no approved product for women. Here's what was said, what the evidence supports, and how to think about it for yourself.
Perimenopause · Contraception
The pill, patch, ring, implant, and hormonal IUD can hide the cycle changes that signal perimenopause. What gets masked, how long you still need contraception, and why AMH tests can't tell you when menopause starts.
Perimenopause · After Baby
Your youngest is two or three and you are still exhausted, foggy, and short-tempered. Postpartum thyroid problems, low iron, sleep debt, and perimenopause overlap. What to check and what the research shows.
Perimenopause · Focus & Cognition
Brain fog, missed deadlines, and emotional overwhelm in your late 30s and 40s may be perimenopause, ADHD, or both. What a 2025 population study found, what is still unproven, and how to get a clear answer.
Perimenopause · Work
Losing your train of thought mid-meeting, hot flashes on camera, and sleep that doesn't recover. What the research shows about perimenopause and work, and practical steps that help without disclosing anything.
Perimenopause · Tracking
Sleep scores, skin temperature, and heart rate variability can show patterns in perimenopause, but no wearable can diagnose it. What the data can and can't tell you, and how to use it with your clinician.
Perimenopause · Early Signs
Tired, anxious, sleeping badly, and cycles changing in your late 30s or early 40s. It may be perimenopause, but several other conditions look the same. What to rule out, what to test, and when testing is useful.
Perimenopause · Early Signs
Your periods arrive on schedule, but sleep, mood, and PMS have changed. Hormones start shifting before cycles become irregular. What the research shows, what to track, and what to ask for.
Perimenopause · Mood & Anxiety
New anxiety, irritability, or rage in your 40s may be perimenopause, an anxiety disorder, or both. What the SWAN research shows, the clues that separate them, and what treatment actually has evidence.
Menopause · Symptoms
Burning mouth, ringing ears, frozen shoulder, crawling skin, electric zaps, palpitations, dry eyes. The menopause symptoms that don't make the usual lists, why they happen, and which ones need a closer look.
Menopause · Oral Health
A burning, scalding, or numb mouth with nothing visibly wrong is one of the least-known menopause symptoms. What the research says about burning mouth syndrome, what to rule out first, and what helps.
Menopause · Balance & Hearing
Spinning when you roll over in bed, ringing in your ears, a floaty off-balance feeling. How estrogen affects the inner ear, what's well supported and what isn't, and when dizziness needs urgent attention.
Menopause · Joints & Muscle
Frozen shoulder peaks in women aged 40 to 60, the same window as perimenopause. What the research says about estrogen and joint pain, what else to rule out, and what to do before the shoulder locks up.
Menopause · Skin & Nerves
Itching with no rash, a feeling of insects crawling under the skin, tingling hands, sudden electric zaps. The skin and nerve symptoms of menopause are real, under-studied, and worth sorting from their look-alikes.
Perimenopause · Heart
Fluttering, skipped beats, or a racing heart in your forties are common in perimenopause. What the research shows, what to get checked so you know it's hormonal, and which symptoms mean go now.
Menopause · Eye Health
Gritty, burning, blurry eyes are common around menopause, and the hormone story is more complicated than low estrogen. What the research shows, what to rule out, and what actually helps.
Metabolic Health · GLP-1
Two oral GLP-1s are now on the market and a third generation is coming. Here's how the pills compare to the injections on weight loss, convenience, cost, and the muscle-and-bone question that matters most after forty.
Metabolic Health · Muscle & Bone
Up to 40% of what you lose on a GLP-1 can be lean tissue. In midlife that's muscle and bone you won't easily get back. The protocol I build around every GLP-1 prescription — and what the new muscle-preserving drugs actually showed.
Stress · Cortisol
The most common reason a good hormone protocol fails isn't the protocol. It's a stress response that never gets to stand down. Why nervous-system regulation has become the first step in functional medicine — and what it looks like in practice.
Gut Health · Skin
Rosacea at 45, acne along the jaw, skin that looks tired no matter the serum. The gut–skin axis is real, it's bidirectional, and in midlife it's tangled up with your hormones. What the research shows and where to look first.
Hormone Archetypes · Cortisol
Years of high output on a stress system that never got to reset. Here's the physiology behind the Bossy Betty archetype — the cortisol crash — and where recovery actually starts.
Hormone Archetypes · Cortisol
Her cortisol total may be normal — but the daily rhythm is running upside down. The Wired Wendy archetype explained: the inverted curve, the 10 PM second wind, and how to flip it back.
Hormone Archetypes · Thyroid
Weight-loss resistance, cold hands, brain fog, and a TSH someone called normal. The Plateau Patty archetype is thyroid and metabolic slowdown — and the gap between normal and optimal is where she lives.
Hormone Archetypes · Estrogen
Heavy periods, breast tenderness, mood swings that track the calendar. The Moody Maven archetype is estrogen dominance — and it's usually a clearance problem, not a production problem.
Hormone Archetypes · Perimenopause
Hot flashes, 3 AM waking, cycles that don't behave, moods that feel borrowed. The Hot Mama archetype is perimenopause onset — estrogen swinging while progesterone falls — and here's how to steady it.
Hormone Archetypes · Gut Health
Bloating that builds through the day, food reactions, irregularity — and hormone symptoms riding along. The Bloated Brenda archetype is the gut-hormone axis, where estrogen is meant to leave the body and doesn't.
Hormone Archetypes · Blood Sugar
Afternoon crashes, cravings, weight at the waist, and a fasting glucose someone called fine. The Sugar Sherry archetype is insulin resistance — the cells have stopped hearing the signal — and it's reversible.
Hormone Archetypes · Menopause
A year past your last period and still exhausted, foggy, dry, achy, and losing muscle. The Depleted Debbie archetype is post-menopause depletion — the steady state after the swings — and it's the one women are told to simply accept.
Hormone Archetypes · Progesterone
New anxiety, a racing mind at night, PMS that turned into dread, a cycle that's shortening. The Anxious Annie archetype is low progesterone — and the calming brain chemistry that went with it.
Perimenopause · The Full Arc
Menopause is one day. Everything else has a different name, a different hormonal signature, and a different set of things worth doing. Here is the whole arc, laid out.
Peptides · Regulation
An FDA advisory panel voted against its own agency scientists and recommended six peptides for compounding. It was genuinely remarkable. It also changed nothing about what is legal today, and that gap is where people are getting confused.
Perimenopause · Mood & Cognition
A woman with no history of anxiety develops it at 44 and is told she is stressed. There is a receptor-level explanation, and it deserves to be part of the conversation before a prescription is.
Peptide IQ · Find Your Fit
I built an assessment that will sometimes tell you not to take a peptide. That is not a flaw in the design — it is the most useful thing it does.
HormoneIQ™ · Find Your Pattern
Two women with identical symptoms can need opposite things. That is why generic hormone advice fails so reliably — and why I started sorting patterns instead.
Weight Loss · Hormones
You're eating well, exercising consistently, and still the scale won't budge. Before you blame willpower, consider the hormonal drivers of weight loss resistance most doctors never test.
Metabolic Health · Comparison
One acts on a single receptor, the other on two. The head-to-head trial produced a clear winner on weight — and a finding about women specifically that most coverage skipped entirely.
Perimenopause · Women's Health
Hot flashes and irregular cycles get all the attention — but perimenopause can begin years earlier with symptoms most women (and their doctors) never connect to hormones. Here's what to watch for and when to act.
Sexual Health · Desire
Unlike almost everything else on this menu, this one has a genuine FDA approval for a women's health condition. The catch is which women the approval covers — and it may not be the ones asking.
Thyroid · Functional Medicine
Fatigue, weight gain, hair loss, cold intolerance, brain fog — these symptoms point to both thyroid dysfunction and hormonal imbalance. Conventional medicine often tests one and misses the other. Functional medicine tests both — and looks at how they interact.
Peptides · Gut & Tissue Repair
It began as a gut compound and became famous for tendons. For a lot of women, the original application is still the more interesting one.
Sleep · Perimenopause
Falling asleep fine but waking at 3 AM is a signature perimenopause pattern. Here's the physiology behind it and where to start.
Peptides · Growth Hormone
It is the one growth hormone peptide that was once an approved drug. That history is the most interesting thing about it, and the most useful context for deciding whether it belongs in your plan.
Energy · Cortisol
The afternoon energy crash isn't a willpower problem. It's usually a cortisol, blood sugar, and perimenopause story — here's how to read yours.
Peptides · Mitochondria
Most longevity peptides have thin human evidence. This one is different — it has been through real clinical trials under the name elamipretide. Here is what that research actually studied, and what it did not.
Testing · Functional Medicine
Standard lab ranges answer a different question than the one you're asking. Here's what 'normal' actually means and which markers deserve a closer look.
Peptides · Brain & Mood
Brain fog and anxiety that arrive in your forties are not a personality change. They have a physiology, and it is usually hormonal — which is where any conversation about nootropic peptides has to start.
Peptides · Skin & Collagen
This is the one compound on the peptide menu where the topical version has better human evidence than the injection. That is worth knowing before you choose.
Peptides · Growth Hormone
It's often called "growth hormone therapy," which isn't quite right — and that distinction changes everything about how it works and who it suits.
Peptides · Visceral Fat
Most peptides in this category are investigational. This one is an approved drug — though not for the reason most people are asking about it. The distinction is worth understanding.
Peptides · Recovery
Joint pain that arrived out of nowhere. Workouts you can't bounce back from. Here's what the research actually shows about the two peptides behind the "Wolverine" protocol — and the hormonal context most articles leave out.
Peptides · Immune Function
Your thymus starts shrinking in adolescence and is largely fatty tissue by midlife. This peptide comes from what that gland used to produce — and the autoimmune caution matters more than most articles admit.
Peptides · Skin & Collagen
The most dramatic skin changes of a woman's life aren't a skincare failure — they're an estrogen story. Where the copper peptide GHK-Cu fits, and what it can't fix on its own.
Peptides · Metabolic Health
It is one of the few peptides your own mitochondria produce. Researchers have called it an exercise mimetic — a description worth unpacking carefully, because it is both the most interesting and most misused thing said about it.
Peptides · Gut–Skin Axis
Some women come in with a gut problem. Some with a skin problem. A surprising number have both — and no one has connected the two for them. The gut–skin axis, explained.
Antioxidants · Detoxification
It is genuinely one of the most important molecules your body makes. That is exactly why the marketing around injecting it deserves a careful, skeptical read.
Metabolic Health · GLP-1
The medication works. The question no one asks loudly enough is what you lose alongside the fat — and in midlife, that question has a much sharper answer than it does at thirty.
Peptides · Longevity
It is marketed as the closest thing to a telomere drug. The research base is real but narrow, and mostly published in one country over several decades. Here is what that actually means for a woman considering it.
Metabolic Health · GLP-1
It hits two receptors instead of one, and the head-to-head trial found women responded even more strongly than men. That difference is worth understanding — along with a contraception interaction most women are never told about.
