Microplastics, Toxins, & the Search for Solutions
Welcome to another edition of the Doctor’s Note where we talk about what’s on our minds when it comes to your health.
This week I sat down with my long-time friend and fellow health innovator, Steve Nice, to dig into a topic I’ve been itching to discuss: microplastics, forever chemicals, and the solutions we have at our fingertips—especially the fascinating compound chitosan. Steve is one of the developers behind DigestShield, the best gut pill I’ve seen in decades of practice, and he brought invaluable insight into how this unique, positively-charged form of glucosamine can help us combat a growing number of environmental toxins. We unpacked not only the ability of chitosan to bind and potentially remove negatively charged threats like pathogens and toxins, but also its promising applications against the ever-present and increasingly alarming issue of micro- and nanoplastics that infiltrate our food and water.
Chitosan—a safe, biodegradable, and non-toxic substance—has become more than just a gut health supplement. Steve shared how it’s being explored for uses ranging from extending food shelf life (by replacing harsh preservatives) to possibly reducing mold exposure and adsorbing harmful chemicals found in water and Tupperware (for example). While large-scale clinical trials are still catching up, the common sense approach of reducing personal toxic load rings true. Simple changes, like switching from plastic to glass containers or removing plasticware from your kitchen, pair with smart supplementation strategies to form a practical defense against modern contaminants. I’m excited about this frontier in health, especially the potential crossover benefits for inflammation and overall healthspan.
PODCAST NOTES
Chitosan is a remarkable, positively charged form of glucosamine that acts as a molecular binder for anything negatively charged, including many harmful pathogens, toxins, microplastics, and even certain forever chemicals. Its mechanism relies on electrostatic attraction, allowing it to attach, envelop, and help remove substances that may otherwise accumulate in our bodies.
Microplastics and nanoplastics—tiny particles that infiltrate our food and water systems—are a growing concern due to their ability to cross the gut-blood barrier and bioaccumulate within tissues. Scientific research is starting to reveal the dangers they pose to human health, ranging from chronic inflammation to potential risks for cancer and other systemic illnesses.
Chitosan’s positively charged molecules provide a unique way to bind and potentially remove these microplastics and forever chemicals from the digestive tract, preventing their entry into the bloodstream and reducing overall toxic load. Though large definitive clinical trials are awaited, the current science and practical logic support its proactive use.
Traditionally, most commercial chitosan has been sourced from shellfish, but as Steve Nice explained, mushroom-derived chitosan offers superior safety, purity, and sustainability—making it more suited for human consumption, especially in dietary supplements like DigestShield and Microplastic Protect.
Shield Nutraceuticals, the team behind DigestShield, is expanding the use of chitosan far beyond gut health—experimenting successfully with its ability to replace toxic food preservatives like BHA and BHT in bread and tortillas. This opens possibilities for safer, more natural food preservation using a biodegradable, non-toxic compound.
Everyday environmental exposure to harmful substances is often underestimated. For instance, chemicals from auto tires (such as PFAS) are washed into our water supply with every rainfall, and plastics from everyday items like Tupperware or water bottles can leach into our food and drinks—encouraging all of us to be mindful of our daily choices to limit this exposure.
Simple lifestyle adjustments—such as removing plastic containers from your kitchen, avoiding microwaving food in plastic, and opting for glass or stainless steel when possible—can significantly cut down daily intake of microplastics and other harmful chemicals, forming the foundation of practical, common-sense health protection.
Chitosan stands out not only for its toxin-binding capacity but also for its anti-inflammatory potential, given its relationship to glucosamine. Many users, myself and Steve Nice included, have reported incidental relief from bloating and even arthritis pain, hinting at important crossover benefits for systemic health and inflammation management.
The threat of microplastics and forever chemicals is a modern reality we can’t ignore, but it is also one we don’t have to face helplessly. Simple changes in our daily habits, paired with safe, intelligent supplementation like chitosan, can reduce toxic load and protect our healthspan.
As always, I encourage you to stay informed, take practical steps to safeguard your environment, and consider safe, science-backed products like DigestShield and Microplastic Protect as part of your wellness arsenal. Let’s keep pushing for health solutions that make sense—so you and your family can thrive for years to come.
Stay educated. Stay healthy.
Till next week.
