What if your gut symptoms aren’t about what you’re taking, but who you’re feeding?

Gut change doesn’t start with a supplement aisle sweep. It starts with the small but mighty species running your internal ecosystem. In this episode, functional naturopath Dan Sippel joins us to unpack how keystone bacteria shape gut barrier integrity, immune tolerance and metabolic health, and why the right polyphenols, fibres and bile acids can stabilise a volatile gut without triggering flare-ups.

We explore short-chain fatty acids, especially butyrate, as the microbiome’s currency, influencing inflammation, insulin sensitivity and even brain signaling. Dan shares a laddered strategy for IBS- and SIBO-prone patients: start with low-aggravation polyphenols like pomegranate peel and green tea to lift Akkermansia and Bifidobacterium; introduce partially hydrolysed guar gum as tolerance improves; then progress to resistant starch once the gut lining calms. Along the way, we break down cross-feeding, when direct butyrate makes sense, and why single-strain probiotics only work when you know the strain’s job.

We also dive into bile acids as the missing link in many stuck cases, including constipation, fat maldigestion, hormone symptoms and perimenopause transitions. You’ll learn how dysbiosis disrupts primary-to-secondary bile acid conversion and how to run a practical gut oil change using choleretics, ox bile or TUDCA. Plus, we cover iron repletion without microbiome damage, the role of sleep and melatonin in T-reg signaling, vagal tone support with L-theanine and kava, and a simple daily polyphenol five you can rotate with patients: cacao, blueberries, pomegranate, raw carrot and green tea.

If you’ve cycled through fibres, probiotics and antimicrobials without lasting results, this conversation offers a sequence that sticks. Build the terrain first, protect keystone species, match fibres to the phase, and retest to prove progress as SCFAs rise and inflammation falls.

Why isn’t your acne responding, no matter how “clean” your skincare routine is?

In this eye-opening episode, skin specialist nutritionist Jacinta Barbagallo shares why stubborn breakouts rarely start on the skin’s surface—and why real solutions lie far deeper. Together, we explore the three root causes of acne: retention keratosis, hypersebum secretion, and skin pH imbalance, and the surprising internal drivers behind them, from nutrient deficiencies and cortisol surges to gut dysfunction and metabolic imbalances.

Jacinta unpacks how to go beyond surface-level treatment with targeted clinical tools like strategic blood testing (e.g. SHBG, fasting glucose, insulin, hormone panels) and foundational nutritional strategies, including 30g of protein per meal, omega fatty acid balance, and key herbal medicines like burdock, Oregon grape, and peony licorice.

Most importantly, she reframes what progress really looks like. With hormones taking months to recalibrate and skin cells needing 6–8 weeks to renew, Jacinta shares what signs to look for along the way, like faster breakout recovery and reduced inflammation.

Whether you're navigating your own skin challenges or supporting clients through theirs, this episode offers a comprehensive and empowering roadmap to finally understanding what your skin is trying to tell you.
