Ep. 127: Who's Eating Your Iron? 3 Hidden Reasons Your Ferritin Won't Budge Sep 23, 2026

Show notes

What if something else is getting to your iron before you do?

This week, Dr. Heather picks up where last week's episode left off. She explains why your iron panel works like a balance sheet: it can show you what's in the account, but it can't always show you who's spending it. Then she walks through the three hidden suspects she looks for first when a client's ferritin refuses to budge. One of them is among the most common infections in the world, and most people who have it never know. They can all go unnoticed for years, and none of them show up on a standard iron panel.

You'll learn:

Why "absorption is the problem" is a correct conclusion that still leaves most women stuck
The three suspects that can quietly drain your iron, and the clues that point to each one
Why your body sometimes hides iron from you on purpose
Why treating off a symptom list can make things worse, and what order of testing makes sense instead

Ep. 126: You've Been Taking Iron for 2 Years For Low Ferritin. Here's What This Is Telling You Sep 17, 2026

Show notes

Dr. Heather's ferritin was 9 four months postpartum, and she had a doctorate in clinical nutrition at the time. She still couldn't fix her own labs, and she spent months doing exactly what you've been doing: assuming she had the wrong iron rather than the wrong theory.
This episode takes apart the belief that almost every woman with low ferritin is operating under. Low ferritin, therefore more iron. It's the most reasonable belief available, it's what your doctor believes, and for some women it works perfectly. If you're still listening to podcasts about your ferritin, you're not one of those women.
Dr. Heather explains how ferritin works like savings, and taking iron is making a deposit. You can walk into the bank every week and hand them twenty dollars, and if you're spending more than you earn, your savings will not grow.
Then she covers the three places the deposit disappears, plus the reframe for anyone who finishes this episode feeling like they wasted two years and four hundred dollars on supplements.
What you'll learn in this episode:

Why the belief that iron fixes low ferritin keeps women stuck for years, and how it converts every failure into a reason to try the same thing again
What your ferritin number actually reports, and why it can't tell you anything about the cause on its own
The three places your iron goes missing
Why some women feel worse on high-dose iron rather than better
The four blood markers to hold out for if your provider will only run a handful

Ep. 125: Iron, Copper, and Gut Irony Roundtable Discussion Sep 04, 2026

Show notes

Round two with the gutTogether team. Macy and Tyler are back, and this time we're talking about the iron and ferritin cases that have filled our caseload for the last six to eight months. If you've taken iron for months and watched your ferritin barely budge, or you've had an infusion and ended up with brand new GI symptoms, this conversation explains exactly why that isl.

We get into the iron recycling system, why copper and ceruloplasmin quietly run the whole operation, what gut infections do with the iron you take, and why ferritin sometimes drops before it climbs.

Plus the question we get in our inbox constantly: should I just get the infusion?

Ep. 123: Your GI Issues Are Costing You (And Not In The Way You Think) Aug 19, 2026

Show notes

You can count the cost of your gut issues in supplements, copays, and elimination diets. But the biggest cost has never shown up on a single receipt, and chances are you've never once added it up.

On this episode, I'm talking about the bandwidth your symptoms are quietly taking from you every single day. I'm sharing what surprised me most about my own healing after twenty years of GI issues, the moment I realized how much mental energy my symptoms had been eating, and what my clients tell me they actually got back when their bloating resolved (hint: nobody ever says "my bloating score improved").

Ep. 122: Generational Health: 9 Out of 10 Babies Are Missing Key Gut Bacteria, with Dr. Stephanie Culler or Persephone Jul 29, 2026

Show notes

Nine out of ten babies in the US are now missing one or more of the keystone bacteria their immune system needs to develop properly.

Stephanie is a PhD scientist, co-founder and CEO of Persephone Biosciences, and a mom who built her company's biggest study after a pediatric researcher asked her a question that stopped her cold: if you can fix the microbiome of cancer patients, why not fix it in babies? That question led to MyBabyBiome, the largest microbiome study of US infants to date, and to the discovery that something has shifted in how babies acquire their earliest gut bacteria.

We get into what "missing" actually means (as in, undetectable even with modern DNA sequencing), why C-section babies are twice as likely to be affected, why breast milk alone doesn't always fix it, and why Stephanie now tells clients that the most important inheritance you can give your kids is your microbiome. We also cover why the probiotic on the shelf at Whole Foods probably isn't doing what you think it's doing, and why it's genuinely not too late to shift things as an adult, even if you've had gut issues since childhood.

Dr. Stephanie Culler, PhD, is the co-founder and CEO of Persephone Biosciences. She earned her PhD in Chemical Engineering at Caltech, where she focused on gene therapies for cancer, and spent the first several years of Persephone's existence developing microbiome-based cancer therapies before shifting the company's focus to infant and toddler gut health after becoming a mother. She led MyBabyBiome, the largest study of the US infant gut microbiome to date, which found that 9 out of 10 US babies are missing one or more keystone Bifidobacterium species linked to healthy immune development (published in Communications Biology, 2025).

Persephone Biosciences makes Bloom (for infants 0 to 12 months) and Thrive (for toddlers 12 months and up), synbiotics that pair specific Bifidobacterium strains with human milk oligosaccharides (HMOs) and vitamin D.

Ep.121: Why Minerals Fix What Protocols Can't with Lisa Pitel-Killah of Vykon Customs Jul 21, 2026

Show notes

Minerals are often the missing link in any health related concern AND the biggest needle mover for individuals who have "tried everything".

If you've done the SIBO protocol, the parasite cleanse, the supplement stack, and your body still isn't responding, this episode is probably the piece you've been missing. Lisa Pitel-Killah is the founder of Vykon Customs and one of the people I trust most in the mineral world (I did my HTMA level one and level two training with her), and in this conversation we cover why minerals have to come before every other protocol, what's actually driving estrogen dominant symptoms that never show on a hormone panel, the truth about calcium supplements and constipation, how to think about binders like humic/fulvic and zeolite, and the clinical reason most gut protocols plateau before they should. Whether you are an individual struggling with health concerns or a practitioner curious about minerals, this is a great listen!

Ep. 120: The Cyclospora Outbreak: A Gut Health Dietitians Insights on What It Is, Why It's Spreading, and What to Actually Do Jul 16, 2026

Show notes

There's a parasite moving across the country right now so Dr. Heather went down the rabbit hole to give you a clear way to think about the 2026 Cyclospora outbreak.

If you've had a stomach bug over the last couple of weeks that seemed to clear up and then came roaring back, this one is worth your time. That relapsing pattern is one of the biggest clues for this particular infection, and it's the thing most people miss.

Heather breaks down what Cyclospora actually is, why this outbreak has been so hard to trace, what genuinely lowers your risk at the grocery store and in your kitchen, and exactly what to do if you think you have it. Including the one thing that actually clears it, and the honest line between real treatment and the supplements that only ever play a supporting role.

Ep.119: Your 2PM Slump Is Not Normal, Here's What Your Body Is Actually Saying Jul 09, 2026

Show notes

If you've accepted the 2pm crash as just "who you are," this episode is going to challenge that.

That afternoon wall with the brain fog, the chocolate craving, the counting down until bedtime, isn't a personality trait. It's your body telling you something. And in most cases, there are very real, very fixable reasons behind it.

In this episode, we're talking about what's actually driving your afternoon energy crash: blood sugar instability, mineral depletion (magnesium, sodium, potassium, iron, and copper), and what it actually means to be hydrated. Plus, four simple habits to try for the next 30 days, and a few mineral-rich mocktail recipes to replace that third cup of coffee.

And if you've already tried all of it and you're still crashing, that's exactly what HTMA testing is for. Instead of guessing what your body needs, you get the data.

Ep. 118: Why Travel Makes You Constipated (and Why It Sometimes You Feel Better) Jul 01, 2026

Show notes

Think about the last trip you took. Were you actually there for it, or were you running a quiet background math equation the whole time, tracking what you ate and wondering if you'd be too bloated for dinner?

For a lot of people with gut issues, travel is something to survive rather than enjoy. But here's what's interesting: some of the women Dr. Heather works with who struggle the most at home actually feel better on vacation. They eat foods they normally avoid, skip their usual protocol, and come back more regular and less bloated than they've felt in months.

In this episode, Heather breaks down the actual physiology behind both experiences, why travel throws your gut off and why it sometimes fixes it, and gives you a practical plan for your next trip so you can be present instead of managing symptoms the whole time.
