Low ferritin is one of the most overlooked root causes of feeling cold all the time, restlessness, and chronic fatigue - and "just taking iron" isn't the answer. In Episode 1, Sarah Kleiner shares her personal journey with low ferritin, why standard iron advice fails, and what actually moved the needle for her.
She breaks down the connection between gut health and ferritin levels, why you can't just supplement iron without addressing absorption, the role of stomach acid (HCL) in iron uptake, how estrogen clearance is tied to iron status, and her 90-day testing protocol for tracking ferritin. If you've been told your ferritin is "normal" but you still feel terrible, this episode is for you.

Why It Takes More Than Hormones to Fix Your Hormones in Perimenopause and Menopause
Wednesday, September 30, 2026 • Duration 51:11
Sarah Kleiner welcomes Dr. Anna Cabeca to discuss perimenopause/menopause support for hormone-hesitant listeners, hormone users, and those wanting non-hormonal approaches. Cabeca emphasizes “it takes more than hormones to fix your hormones,” advocating foundations like circadian and lifestyle factors, detoxification pathways, gut and mitochondrial health, and working with individual physiology rather than one-size-fits-all hormone protocols; she frames treatment as hormone “replenishment” and notes benefits of progesterone, pregnenolone, DHEA, and sometimes estrogen/testosterone depending on metabolism and clearance. They discuss increased post-pandemic inflammation and autoimmune issues (Hashimoto’s, dysbiosis), rising MCAS/histamine intolerance linked to estrogen fluctuations or impaired estrogen clearance, and practical supports including food/stress diaries, oxytocin-boosting practices, daily bowel movements, and drainage/lymph strategies. They also cover keto/carnivore drawbacks for some women (uric acid, weight gain), thyroid markers like reverse T3, ferritin optimization, and the importance of individualized, terrain-focused care. Cabeca shares where to find her work and programs
I share the exact nutritional strategy I used to triple my ferritin and regulate my full iron panel in 90 days - without relying on iron supplements alone. If you're struggling with low ferritin, iron dysregulation, or chronic undereating patterns that are elevating your hepcidin, this video walks you through everything I changed in my diet.
You'll learn why carb restriction raises hepcidin, why heme iron beats non-heme sources, how resistant starches support estrogen clearance, and how eating three warm cooked meals a day (including congee!) helped me rebuild my blood.

What to ask for if you suspect your thyroid (and your doctor says you're fine | Dr. Amie Hornaman
Wednesday, September 23, 2026 • Duration 01:01:56
Sarah Kleiner welcomes Dr. Amie to discuss why many people with hypothyroid symptoms are dismissed after only TSH (and sometimes T4) testing and placed on T4-only medication without improvement. Dr. Amie shares her own journey through multiple doctors before being diagnosed, learning that T4 must convert to active T3, and ultimately finding functional medicine support with more thorough testing and individualized treatment. They discuss tailoring thyroid hormone replacement, how low ferritin and stress can affect tolerance to T3, and how long-term carnivore/ketosis may lower free T3 for some people. They cover thyroid’s links to metabolism, temperature regulation, mood, and long-term risks, address misconceptions about T4 and cancer via reverse T3, and emphasize getting a full thyroid panel and not accepting dismissal. Dr. Amie shares resources, including a quiz at dramy.com/quiz

How Estrogen Clearance Affects Breast Cancer & Menopause Risk with David & John | Mara Labs
Wednesday, September 16, 2026 • Duration 01:10:48
Sarah introduces an Evolving Wellness episode on estrogen clearance, perimenopause/menopause, and why estrogen therapy isn’t one-size-fits-all, then interviews John and David from Mera Labs, whose work on sulforaphane began after both of their wives faced breast cancer. They explain how sulforaphane activates NRF2, supporting phase 2/3 detoxification, antioxidant responses, mitochondrial function, and mitophagy, and discuss circadian oscillations of NRF2. Sarah shares her experience of heavy bleeding, PMS, and low ferritin improving after several cycles on their product, with benefits also noted for her autistic teen. The guests differentiate stabilized sulforaphane from glucoraphanin products, describe synergy from added PEITC, discuss dosing timing, toxins/microplastics and endocrine disruptors, DIM questions, stress and vagal regulation, and note a rare microbiome-driven estrogen recycling condition linked to galactorrhea

Reversing Plaque? Why Heart Disease Is Actually Metabolic | Dr Anthony Jay
Wednesday, September 9, 2026 • Duration 01:08:57
On the Evolving Wellness podcast, host Sarah interviews returning guest Dr. Anthony Jay (PhD biochemistry; former Mayo Clinic researcher) about his book Sugar Beat: How Sugar, Not Cholesterol, Destroys Arteries and his broader critique of mainstream cardiology. Jay cites a 28,000-person study where insulin resistance had the highest heart-attack hazard ratio (6.4) versus hypertension (2.2), triglycerides (2.1), and LDL (1.38), arguing doctors overemphasize cholesterol while neglecting insulin and HOMA-IR. He claims statins increase arterial calcification and diabetes risk, criticizes organizations like the American Heart Association, and disputes fears around LDL, ApoB, and Lp(a), describing them as fat-transport/oxidation-related. Jay recommends focusing on metabolic health, diet and fasting to promote fat burning and plaque reversal, cautions about processed foods and mislabeled oils, discusses CAC vs CCTA imaging variability, and notes genetic nuances such as iron-related risk and sitosterolemia.

How Light Can Heal Your Brain: Autoimmune, Seizures & Neurology | Dr. Brandon Crawford
Wednesday, September 2, 2026 • Duration 01:05:30
In this podcast episode, Dr. Brandon Crawford, a chiropractor with training in functional neurology, discusses his work combining functional neurology with photomedicine/photobiomodulation, describing an early pediatric case where laser use appeared to spur unexpected brain development. He explains why some lasers may worsen symptoms (e.g., seizures) due to beam “hot spots,” wavelength energy, and dosing factors such as frequency and duty cycle, emphasizing that light is “information” and not always about increasing ATP. The conversation highlights foundational health strategies—sunlight, grounding, deuterium-depleted water, cold exposure, and reducing screens/non-native EMFs—sharing a case where these improved a child’s labs and heavy metal burden. Crawford outlines a developmental functional neurology framework (sensory mapping, primitive reflexes, muscle spindle “conversion,” spinal cord/motor neuron involvement) and discusses PANS/PANDAS as autoimmune encephalitis, focusing on neuroimmune imbalance and individualized treatment that may include targeted activation, nuanced photobiomodulation, and regenerative options like extracellular vesicles, VSEL procedures, and patented Dezawa MUSE cells. He also notes rising neurodegeneration possibly linked to geomagnetic shifts and the South Atlantic Anomaly, and provides ways to contact his clinic and options for telehealth versus intensives.
Hormones, Histamine, and Finally Feeling Human Again | Sheila Kenneal
Wednesday, August 26, 2026 • Duration 01:04:20
Host Sarah Kleiner welcomes naturopath and educator Sheila Kennealy, an American living in France who teaches functional blood chemistry and runs The Practitioner Blueprint course. Sheila shares how early health challenges—Roaccutane, rapid weight loss, heavy antibiotic use, liver and biliary issues, mold exposure, and family trauma—shaped her focus on biochemistry, meditation, and the link between psychological and physiological freedom. They discuss environmental contributors to modern illness (non-native EMFs, food, water, air, mold, viral reactivation), the importance of nervous system regulation, and why dogmatic diets and chronic macronutrient restriction can backfire, especially for women. They emphasize pattern recognition in labs over single markers, seasonality in interventions, supplement fatigue, and nuanced approaches to GLP-1s, HRT, and MCAS/POTS, including the viral Pepcid/Allegra PMDD trend.
What Every Sports Parent Should Know About Brain Injury - CTE and Red Light Therapy | Dr. Larry Carr
Wednesday, August 19, 2026 • Duration 01:02:20
On the Evolving Wellness Podcast, host Sarah interviews Larry, a former football player and PhD in exercise physiology, about his worsening anxiety, depression, and cognitive symptoms after years of collision sports and a 2010 diagnosis of significant brain damage. After meeting CTE researcher Ann McKee in Boston and learning of near-infrared light research at the VA, Larry entered a study using a near-infrared headset and reports major improvements in mood, PTSD measures, cognition, and MRI functional connectivity, with symptoms returning when he stopped and improving again on a home device. He describes subsequent research in first responders and a season-long BYU football study comparing sham vs active headsets, reporting broad gains in performance measures and MRI indicators showing inflammation increases in controls but a net loss of inflammation and better axon health in treated players. Larry discusses practical use (20 minutes, typically mornings, three to five days weekly) and argues the approach is disease-modifying and relevant for athletes, veterans, and others.
