What About Mushrooms for Prostate?

By Geo Espinosa – For prevention-oriented men, the defensible recommendation is dietary: three or more mushroom meals per week across varied species. Shiitake, oyster, maitake, and king oyster are the antioxidant-dense choices. The nutritional upside is real — high fiber, low glycemic index, very low fat, protein content in some species rivaling animal sources.

Can GLP-1 Receptor Agonists Cause ED? — Reading the Signal in the Noise

By Geo Espinosa – The integrative goal is to remodel the metabolic environment that drives erectile failure in the first place. That means restoring endothelial function, preserving lean mass, supporting endogenous testosterone, normalizing inflammation, and rebuilding the autonomic balance that allows arousal to translate into a usable erection.

Weight loss is the lever. Sexual function is one of the most honest readouts of whether the lever worked.

Can an Estrogen Patch Help Prostate Cancer Patients?

By Geo Espinosa – In integrative medicine, we’ve always understood that a treatment your patient can’t tolerate isn’t actually treating anything. Quality of life is not a soft endpoint. It’s time to add transdermal estradiol to our fluent vocabulary of ADT options — not as a fringe alternative, but as a legitimate, evidence-supported choice.

PSA Tests

By Geo Espinosa, ND, LAc – Current diagnostic tools, such as PSA, mostly predict biopsy positivity or the presence of clinically significant cancer, but do not show the actual risk of dying from prostate cancer, how life expectancy and comorbid disease modify that risk, or whether there is any meaningful benefit to continued screening.

Melatonin: Myths and Mechanism

By Geo Espinosa – Melatonin is neither the benign panacea patients assume nor the cardiotoxic agent suggested by headlines. Its value lies in circadian stabilization, vascular support, REM enhancement, and antioxidant function—when used correctly, at the right time, and under clinical guidance.

Prostate Cancer Care Choices

By Geo Espinosa, ND, LAc – Two decades ago, localized prostate cancer care mostly meant an open prostatectomy or ~40 fractions of pelvic radiation. 

Today, the menu is far broader—robot-assisted techniques that prioritize functional preservation, ultra-hypofractionated radiation that may be delivered in as few as 2 fractions in select protocols, and ≥5 focal therapy modalities that target the index lesion while sparing the uninvolved gland. 

The challenge isn’t a lack of options—it’s matching the right patient to the right intensity at the right time.

Fermented Foods

By Geo Espinosa, ND, LAc – No single food causes or cures disease, but the microbiome science backing fermented foods is getting hard to ignore. A recent review/meta-analysis found that among other benefits, in the trials, eating fermented kimchi was linked with better blood sugar and blood pressure.

Low T and PSA Levels

By Geo Espinosa, ND, LAc – PSA is our main blood test for prostate cancer. But in men with hypogonadism (low testosterone), PSA can look deceptively low—even when high-grade cancer is present, and this can delay diagnosis and treatment at the very early stages, when catching cancer matters the most.

Sleep Fragmentation

By Geo Espinosa, ND, LAc – Poor sleep isn’t just a nuisance—it’s linked with metabolic syndrome, hypertension, heart disease, cognitive decline, and even higher prostate cancer risk over time. Better sleep isn’t a luxury; it’s a foundation for health, clarity, and quality of life. Strength training can help with that.

Coffee and Longevity

By Geo Espinosa, ND, LAc – Coffee headlines often skip what matters in real life: dose, additives, timing, and how your body metabolizes caffeine. Coffee is not a “superfood”. There are no superfoods. But moderate amounts of coffee—especially black coffee or lightly sweetened—can be part of a smart longevity plan, including for men focused on prostate health.

  • The Midlife Women’s Health Summit: Evidence-Based Menopause Care in the Era of Longevity Medicine

    The Ritz-Carlton, Pentagon City 1250 S Hayes St, Arlington, VA, United States
    Hybrid Event

    Menopause Care in the Longevity Era Longevity medicine is everywhere right now. Supplements, protocols, influencer clinics, patients walking in with questions about interventions their doctors have never heard of. What's missing from most of it is the evidence. The Midlife Women's Health Summit is three days on what the research actually says about menopause care when you add a longevity lens. What works, what doesn't, what's being oversold, and what to tell the patient sitting in front of you. Co-chaired by Lisa Larkin, MD, FACP, MSCP, IF, Jen Gunter, MD, FRCS(C), FACOG, DABPM, ABPMR, and Lauren Streicher, MD, FACOG, MSCP; three of the clearest voices in women's health on separating data from marketing.
