Hormonal health isn’t just about ovaries or adrenals—it’s about the full system: your gut, sleep, metabolic balance, and how you live each day. In Episode 16 of the Gut Check Podcast, Pauline Cox guides us through how these pieces fit together for women’s health across life stages—from adolescence through perimenopause and beyond.

In modern wellness discussions, we often focus on macronutrients, exercise, sleep—but we rarely dig into the soil, food supply chain, and hidden chemicals that influence our gut, hormones and long-term health. In this episode, Parker Brook, Founder & CEO of Lovebird Cereal, uncovers how the industrial food system—glyphosate use, refinery of cereals, marketing of “junk” foods—connects directly to gut health, metabolic burden, and hormone function.

Did you know that 70–80% of your immune system resides in your gut? According to renowned microbiologist and microbiome expert Kiran Krishnan, this immune tissue acts like a sampling station, assessing environmental inputs from food, water, and even the air we breathe. "Your immune system gets its training from your microbiome," he explains. "Without it, immune cells are like untrained soldiers — they don’t know friend from foe."

Gut Health & Fertility: Unlocking Women’s Wellness For many women, fertility challenges, cycle irregularities, painful periods or heavy flows are treated in isolation. What this episode reveals is a deeper truth: your gut microbiome, inflammation levels, nutrient status and hormone regulation all play a part in reproductive health — whether you’re pursuing pregnancy now or preparing your body for later. Dr. Lauren Rubal brings together her background in reproductive endocrinology and integrative medicine to show how many fertility and hormonal issues trace back to foundational systems.YouTube+1 The Gut-Fertility Connection You Might Not Be Seeing The gut microbiome helps regulate hormone...

You might think saunas and cold plunges are just for recovery or “biohacking.” But when you dig deeper, contrast therapy (alternating between heat and cold) can support foundational systems: mitochondrial function, circulation, inflammation regulation, gut integrity and hormonal balance.

In Episode 6 of the Gut Check Podcast, Tyler Fish shares how he co-founded Sun Home Saunas and explores how intentional exposure to heat and cold can reshape wellness—not through gimmicks but by leveraging your body’s biology.
