In this episode of Women in the Nude, Sasha Pieterse sits down with David Watumull—CEO and co-founder of Ax3 Life—for an illuminating conversation about astaxanthin, one of nature's most powerful antioxidants, and its potential to revolutionize how we approach longevity and women's health.

David shares the remarkable 25-year journey that began in Hawaii, where he and his father discovered the science behind astaxanthin—a molecule produced by microalgae that gives salmon and flamingos their pink color. Together, they dive into the decade-long pharmaceutical pathway, the pivot to supplements after the 2008 financial crisis, and the groundbreaking NIH-funded study showing a 12% increase in lifespan.

This episode is a masterclass in understanding cellular health, oxidative stress, and inflammation—particularly for women managing PCOS, insulin resistance, and reproductive health challenges. David breaks down complex science into accessible insights about how this molecule works at the cellular level to support cardiovascular health, metabolic function, and overall longevity.

This episode offers a roadmap for taking control of your health through evidence-based supplementation:

Cellular Protection: How astaxanthin spans cell membranes to fight oxidative stress at its source, unlike typical antioxidants

PCOS & Women's Health: Clinical evidence showing improvements in cholesterol, triglycerides, insulin resistance, and reproductive outcomes

The Longevity Connection: Why this is the only supplement in NIH's 20-year testing program to achieve significant lifespan extension while remaining safe

Bridging East & West: How holistic, whole-body approaches can work alongside Western medicine for optimal health

Personalized Dosing: Why baseline lab work and consistent supplementation matter more than quick fixes

In this episode of Women in the Nude, Sasha Pieterse sits down with Kate Regan—registered dietitian, nutritionist and founder of Wholesome Chick Nutrition—for a refreshing and vital conversation about dismantling diet culture and reclaiming your relationship with food.

Kate opens up about her personal journey through disordered eating and how finding the "Health at Every Size" framework completely redirected her career. Together, they dive into the toxic media narratives of the 90s, the current pressures of social media, and Kate’s radical guiding principle: that you and your body are actually on the same team.

This episode is a roadmap for untangling years of diet culture messaging and finding what Kate calls "food freedom."

Your body is your teammate: Shifting from a mindset of combat to one of cooperation is the first step toward healing.

The "Additive" Approach: True nutrition is about what you can add to your plate to feel your best, rather than what you should cut out.

Blood Sugar Balance: Managing PCOS and insulin resistance requires nuance, not restriction.

Ending Intergenerational Diet Culture: The language we use about our own bodies directly impacts the next generation.

Community over Isolation: Recovery and growth happen best when we share our struggles and find collective support.
