Jackie's Take: What's on My Mind in Women's Wellness āļø š¤ š°
𧬠Beyond the Longevity Bros: A Modern Framework for Womenās Preventive Testing
Thereās a reason the phrase ālongevity medicineā tends to conjure images of biohacking bros in cold plunges. The movement has been dominated by men, metrics, and an obsession with optimizationātestosterone titration, peptide stacks, NAD+ infusions, and V02 performance testing.
But for womenāespecially those in midlifeāthe conversation needs a completely different center of gravity.
Weāre not trying to reverse aging with a CGM and a six-pack. Weāre just over here trying to protect brain function, preserve muscle, manage inflammation, stay sharp at work, and feel like ourselves through one of the biggest neurohormonal shifts of our lives.
The problem? The healthcare system still waits for us to break before it pays attention.
Preventive testing in traditional medicine often follows this logic: if thereās no FDA-approved drug or procedure for it, thereās no point in testing for it. But I believe that thinking misses the mark. Because knowing your risksābefore problems startācan help you make proactive decisions that may change the trajectory of your healthspan.
This is where longevity medicine shines. Not as a luxury flex, but when curated for female physiology, it can function as a form of power.
But by the same token, longevity medicine right now feels like the wild, WILD west. Most still arenāt in agreeance about what the term actually stands for. And Iāll be honest with youāitās hard even for the most seasoned clinicians to make sense of what is just over-engineered lip service and what really is worth your time.

So here is a start: I pulled together the longevity testing short list I wish more women had access toāthe kind that I think can help you make moves before things fall apart. A few of these nudge the line between conventional and next-gen care, but if youāre here, I trust youāre ready for that. Wherever I could, Iāve included price points and access tips, so youāll know exactly what youāre in for.
ā Tests That Might Actually Change Your Life
1. Polygenic Risk Scores (PRS)
These tests go way beyond 23andMe. They analyze thousands of genetic variants to estimate your personal risk of diseases like coronary artery disease, breast cancer, and diabetes.
ā”ļø Why it matters: Harvard research shows PRS can predict risk on par with rare gene mutationsāand guide earlier, smarter interventions.
šø Cost: ~$250ā$400, (Myriad, Allelica)
š Use it if: You have a family history of chronic illness or cancer, or want insight that goes beyond basic gene identification. Future versions of PRS will help estimate not just if youāre at risk, but whenāpotentially sparing you years of unnecessary screening, anxiety, or even surgery. This is what truly personalized prevention look like, and Iām here for it.
2. Lipoprotein(a) Testing (Lp(a))
Lp(a) is a sticky, scratchy cholesterol particle that increases heart attack and stroke riskāespecially in women. Itās genetic and doesn't respond to diet, so it often gets ignored.
ā”ļø Why it matters: Estrogen drop during perimenopause increases LDL and inflammation. Lp(a) adds gasoline to that fire.
šø Cost: ~$75ā$100, ask your practitioner to add it your regular blood panel!
š Use it if: You have a family history of early cardiovascular disease or stroke. You technically only need to test this once per lifetime, however there is some evidence to suggest that hormone therapy may lower it modestly.
š§Once you have tested: Use this tool to see how much your Lp(a) level increases your risk of having a heart attack or stroke, and get specific guidance about what you can do to lower your risk if your Lp(a) level is elevated.

3. DEXA Scan (Bone Density)
Standard care says wait until 65. Thatās nonsense. Women can lose 10ā20% of their bone density in the five years around menopause.
ā”ļø Why it matters: Once you fracture, itās too late. DEXA gives you the chance to intervene early with strength training, nutrition, or hormones.
šø Cost: ~$150-200 (DexaFit, BodySpec, or at your local radiology center)
š Use it if: Youāre over 50 and havenāt had a baseline. Every woman deserves to understand her skeletal foundation.
4. Biological Age Testing
These tests track markers like DNA methylation or chronic inflammation to estimate your biologicalānot chronologicalāage. It's one of the most researched epigenetic markers in longevity science. Think of it as your personalized āaging report card.ā
ā”ļø Why it matters: This one is still a bit fringe, and is it imperfect? Yes. But for some, it can be motivating. Especially if youāre stacking habits and want to track impact.
šø Cost: $250ā$500 (GlycanAge, TruDiagnostic)
š Use it if: You love metrics, or want to another data point when tracking response to interventions like HRT, peptides, sleep, and exercise.
ā Tests That Are Not Worth Your Time (or Money)
1. Prenuvo Full-Body MRI
It sounds sexyābut IMO this leads to more stress than substance. Up to 95% of scans show āabnormalities,ā most of which are irrelevant. And even worse, many patients are skipping the proven screenings because they think the whole-body MRI has them covered (TLDR: it doesnāt).
š« Why skip it: False positives lead to unnecessary biopsies, scans, and worry. This is the wellness equivalent of scrolling WebMD at 3am.
šø Cost: ~$2,500 and up
2. Dutch (Dried Urine) Hormone Testing
This is hotly debated in the functional medicine space. But I stand by my POV that while helpful in very infrequent and specific cases, the Dutch is overused with minimal clinical utility. Interpretation is complex, and most decisions can be made based on symptoms and standard labs.
š« Why skip it: It hasnāt been validated for broad clinical use, and most importantlyārarely changes treatment decisions in perimenopause.
šø Cost: ~$300ā$500
3. Telomere & NAD+ Testing
These sound futuristic, but they donāt tell you much thatās actionable. Knowing your telomere length wonāt help you build a real plan.
š« Why skip it: More correlation than causation. These tests arenāt ready for prime timeāand donāt affect your next move.
šø Cost: Varies widely. Pass.
š©āāļø Ground Rules for Smart Testing
You donāt need every testāyou need the right ones. Here's your evidence-based barometer: Will this give me meaningful data I can understand, act on, and use in some way to personalize my care?
Remember these five sanity checks before you invest time, energy, or money:
1. If a test wonāt change what you do next, itās not worth doing right now.
Longevity medicine is about proactive choices. Curiosity without a next step? Thatās just expensive anxiety.
2. Cash-pay doesnāt mean āsketchyāābut it doesnāt guarantee clinical utility either.
Many cutting-edge tools live outside insurance. That doesnāt mean theyāre bad. But it also doesnāt mean theyāre necessary. Clinical utility matters more than novelty.
3. If your doctor wonāt order it, itās likely about infrastructureānot value.
Most providers are trained in reactive care and work under strict billing rules. Thatās not failureāitās a gap longevity medicine is starting to fill. You may have to look elsewhere.
4. More data doesnāt always mean more clarity.
More testing = more ambiguity if itās not done with purpose. Targeted, evidence-based tests are more powerful, and less anxiety-inducing, than broad fishing expeditions.
5. āNormalā isnāt the same as āoptimalāāespecially for women.
Standard ranges werenāt designed around female physiology. If you feel āoff,ā even with normal labs, you deserve to ask more questions. Longevity medicine honors that instinct.

šš§ Research Corner: Effects of Collagen Supplements on Skin Aging šµ
In sad news for skinfluencers, a meta-analysis of 23 trials found no solid clinical evidence that collagen supplements improve skin hydration, elasticity, or wrinkles, with positive effects seen only in low-quality, industry-funded studies. A good reminder that we should always be asking who is funding our research before we buy. š« š°ļø (American Journal of Medicine)
I canāt count the number of times a patientāor a friendāhas brought up Melani Sandersā viral videos. Her āWe Do Not Careā club taps into something so many midlife women feel but rarely say out loud: the rage, the apathy, the sheer exhaustion. Itās messy, humorous, and deeply validating. (NYT)

A new Nature Aging study found that chronic inflammation isnāt an inevitable part of agingāpeople in non-industrialized societies show far lower levels despite similar exposures. The takeaway? āInflammagingā may be more about environment and lifestyle than age itself. (NYT) āļø
A Special Announcement from Jackie at ITSšļø
Imagine this: You've been to multiple doctors. Your labs come back "normal." Yet you're still exhausted, foggy, and frustrated.
Sound familiar?
Here's what's really happening: Most doctors are trained to spot disease, not optimize health. They're looking at outdated reference ranges and missing the subtle patterns that explain why you feel terrible despite "perfect" bloodwork. Meanwhile, you're left wondering if this is just your new normal.
Last week, I watched AI analyze a patient's biomarkers and identify what three specialists had missed ā why her "normal" hormone levels were causing afternoon crashes. The precision was honestly mind-blowing.
This is exactly why I've been quietly developing something revolutionary: a 6-week intensive that combines 15 years of clinical practice with cutting-edge AI technology. You'll learn to become your own health detective, building a personal health copilot that works from the bedroom to the boardroom to the exam room.
This isn't another wellness program. This is clinical-grade health optimization using the same methodology I use in practice, designed specifically for the brilliant, time-pressed women who read this newsletter.
Hereās the thing ā I'm only accepting 50 women for the pilot launch, and my newsletter subscribers get first access before I announce it anywhere else.
