In this episode of The Human Upgrade, Host Dave Asprey explores the hidden health crisis of microplastics with Josephine Musco, founder of Olyxir Tea Strips. From invisible particles accumulating in your brain to hormone disruption affecting fertility, microplastics are everywhere..teabags, water bottles, synthetic clothing, and skincare products. They dive deep into how microplastics mimic estrogen, get stored in fat tissue, and cross the blood-brain barrier linked to Alzheimer’s and dementia. Josephine reveals her patented solution: dissolvable tea strips that eliminate teabag microplastics while delivering concentrated polyphenol benefits. The conversation covers practical detox strategies including infrared sauna protocols, lymphatic support with guarana and yerba mate, prebiotics like acacia gum, and how to reduce exposure through household choices…from leather vs. synthetic fashion to avoiding non-stick cookware. Critical for those planning pregnancy, this episode emphasizes that reducing microplastic exposure before conception protects the next generation’s cognitive and reproductive health.
Microplastics are invading your brain, blood, hormones, and fat tissue, and most people have no idea how deep the damage goes. In this episode, Host Dave Asprey and microplastics expert Josephine Musco break down exactly what these particles are doing inside your body and give you a practical, science-backed action plan to detox, protect yourself, and take back control of your biology.

Josephine Musco is a multidisciplinary entrepreneur, Demeter-certified biodynamic farmer, and winemaker at Chateau Bellevue 1881 in Livermore, California. She is the founder of Olyxir Tea Strips and holds two scientific patents rooted in her deep expertise in botanical medicine and regenerative health. She is best known for translating complex research on aging, nutrition, environmental toxins, and functional medicine into practical daily habits, and for her work exposing microplastics and PFAs as one of the most underestimated drivers of accelerated biological aging.
Dave Asprey and Josephine cover the full picture: how nanoplastics cross the blood-brain barrier and accumulate in postmortem brain tissue, how endocrine disruption from plastics tanks testosterone and drives fat storage, and why your teabag, canned soup, and yoga pants may be among your biggest sources of daily exposure. They also go deep on real solutions, from lymphatic drainage protocols and infrared sauna to supplements like chlorella, lactobacillus, and olive leaf polyphenols that actively help the body clear microplastics and support longevity and brain optimization.
This is essential listening for anyone serious about biohacking, anti-aging, metabolism, brain optimization, supplements, human performance, and smarter not harder approaches to living clean in a toxic world. If you drink tea, cook with plastic utensils, or wear synthetic workout clothes, this episode will change how you make decisions every single day.
