Microplastics in the Human Body

We throw the word around a lot, but what exactly are microplastics?

At their simplest, microplastics are tiny plastic particles less than 5 millimeters in size—small enough to be invisible to the naked eye but big enough to cause serious biological chaos. They may be microscopic, but their impact on the human body is anything but small.

There are two main types you should know about:

• Primary microplastics are deliberately manufactured small. Think microbeads once found in facial scrubs and toothpaste.
• Secondary microplastics are even sneakier. These are the result of larger plastic items—like water bottles, grocery bags, or synthetic clothes—breaking down over time into smaller and smaller fragments.

Where are they hiding? Everywhere.

You’ll find microplastics in bottled water, takeout containers, food packaging, your fleece sweater, your makeup, the air you breathe, and even the rain that falls on your skin.

And once they’re in your body, they don’t just sit there quietly. They travel. They lodge. They interfere.

In other words: it’s not just pollution. It’s invasion.

Dr. Rodney Russell doesn’t mince words: “You’re not just digesting food—you’re digesting plastic waste.”

Microplastics aren’t inert little specks. They’re chemically active invaders—endocrine disruptors and neurotoxins—that mimic hormones, trigger inflammation, and interfere with critical systems in the body. Here’s how the damage unfolds:

Dr. Russell points to alarming new studies showing that microplastics lodged in brain tissue can spark inflammation and cognitive decline. We’re talking about more than just the occasional brain fog—these particles are now being investigated as potential contributors to early-onset dementia, memory problems, and that chronic mental cloudiness so many people can’t explain.

Microplastics breach the blood-brain barrier, a protective shield that’s supposed to keep toxins out of our most vital organ. Once they’re in, they don’t just sit harmlessly—they irritate, inflame, and disrupt.

Plastic particles are molecular mimics. Many act like estrogen, the dominant female sex hormone—but that’s not good news for anyone. These imposters can throw off testosterone levels in men, disrupt menstrual cycles in women, and confuse your thyroid and adrenal glands, leading to fatigue, anxiety, weight changes, and low libido.

Hormone balance is delicate, and plastics are pushing us off the tightrope—without us even knowing it.

Immune Dysfunction & Gut Health

Your gut is supposed to protect you, but microplastics may be making it the front line of a hidden war. Dr. Russell explains that these particles form biofilms—slimy, plastic-coated environments that allow harmful bacteria to thrive and evade your immune system. This weakens your defenses and may even contribute to autoimmune conditions, chronic inflammation, and digestive issues.

The bottom line? Your body is being forced to digest and detox something it was never designed to handle. And the long-term consequences are only beginning to surface.

Detoxing the Modern Way

Modern toxins require modern strategies—and Dr. Russell believes detox starts with small, daily shifts. His approach centers on minimizing toxic exposure and supporting the body’s natural detox pathways, gently and consistently.

Here are our top recommendations for building a cleaner lifestyle from the ground up:

• Zyme – Enzymes that help your body break down plastic-based toxins.
• Fulvic + Humic Minerals – Bind to toxins and escort them out of cells and tissues.
• Infrared sauna – Promotes deep detoxification through sweat.
• Cellular support – Focus on hydration, trace minerals, and mitochondrial nutrients to power up your body’s innate repair systems.

“The body knows how to heal—when supported, not overwhelmed.” – Dr. Russell

• Cookware – Say goodbye to Teflon. Choose cast iron, stainless steel, ceramic, or Saladmaster cookware (Dr. Russell’s top pick).
• Containers & drinkware – Use glass or stainless steel for water bottles, shakers, and storage. Toss plastic bags and swap for glass or stainless steel alternatives.
• Water – Drink distilled or reverse osmosis-filtered water to avoid microplastics and heavy metals.
• Tea – Avoid plastic tea bags; go loose leaf instead.
• Cutting boards – Use wooden boards, not plastic.
• Toothbrush – Swap to bamboo.
• Shopping – Bring cotton reusable bags to avoid plastic.
• Clothing – Opt for cotton and bamboo, even for activewear like leggings, to reduce exposure to synthetic microfibers.

Let’s be clear: microplastics are affecting your mind, your mood, and your metabolism—often without a single obvious symptom until it’s too late.

But here’s the good news: you can take back control.

It starts with awareness. Knowing what microplastics are, where they hide, and how they harm gives you the power to make smarter choices—about your food, your water, your products, your health.

And once you know better? You can do better.
