The Hidden Danger of Microplastics & How to Lessen Your Toxic Load

Microplastics: A Silent Invasion in Our Bodies

It’s no longer a question of if we’re ingesting microplastics—it’s how much. These tiny plastic particles, often invisible to the naked eye, have infiltrated our food, water, and even the air we breathe. Studies now confirm that microplastics are making their way into our organs, bloodstream, and disturbingly, even our brains. But where are they coming from, and how can we minimize our exposure?

Everyday Sources of Microplastics You Might Be Overlooking

On average, studies show that each person consumes about five grams of microplastics every week—that’s roughly the size of a credit card!! But where does this plastic come from?

• Tea Bags: Many commercial tea bags are sealed with plastic fibers that break down when steeped in hot water. Testing by Consumer Lab has shown that microplastics are widespread across major tea brands. That means your soothing cup of tea might be delivering more than just antioxidants—it could be laced with tiny plastic particles.

• Chewing Gum: Most gum contains polyvinyl acetate, a synthetic plastic polymer that contributes to microplastic ingestion. A recent study found that habitual gum chewers had significantly higher levels of microplastics in their bodies. According to the pilot study, "Each gram of chewing gum could release up to 637 microplastic particles, with 94% released within the first 8 minutes of chewing." If you’re chewing gum daily, you might be unknowingly “eating” plastic with every bite.

• Takeout Containers & Bottled Water: Research indicates a correlation between higher microplastic levels and frequent consumption of takeout meals and bottled water. The plastic packaging sheds microplastics into the food and drink we consume. According to this study, “A correlation was observed between elevated microplastic (MP) levels and frequent consumption of takeout meals and bottled water among patients, indicating that MP ingestion through food sources might have contributed to the increased abundance and variety of MPs within uterine fibroids (UFs).” Even if you’re eating clean, your food could still be contaminated just by sitting in plastic containers.

• Household Dust: Microplastics are present in household dust, meaning we unknowingly inhale them daily. Synthetic fibers from carpets, clothing, and furniture shed microparticles into the air. If you’ve ever noticed dust accumulating on surfaces, just imagine how much of it you’re breathing in without realizing.

• Clothing & Textiles: Synthetic fabrics like polyester and fleece shed microplastics into the environment, especially during washing.

• Dental Floss: Many types of conventional dental floss are made from synthetic materials that can release microplastics during use. A study from Harvard found that some flosses not only contribute to microplastic exposure but may also contain PFAS compounds—harmful “forever chemicals” linked to health concerns. That minty glide between your teeth might be leaving behind more than a fresh feeling.

The Health Risks: What Science Is Revealing

Emerging research links microplastic exposure to various health concerns, including:

• Hormonal Disruption: Many plastics contain endocrine-disrupting chemicals like BPA and phthalates, which can mimic hormones and interfere with the body's natural balance.

• Inflammation & Cellular Damage: Studies suggest that microplastics can trigger oxidative stress and inflammation, potentially contributing to chronic illnesses.

• Brain & Organ Infiltration: Microplastics have been found in human placentas, lungs, testicles, thyroid glands, and even brain tissue, raising concerns about long-term neurological and systemic effects. A groundbreaking study published in the New England Journal of Medicine even suggests that microplastics embedded in carotid artery plaque may be linked to a higher risk of heart attack, stroke, and even death.

How to Reduce Your Microplastic Exposure

1. Ditch Plastic Tea Bags: Opt for loose-leaf organic tea or brands that use natural fiber tea bags.

2. Stop Chewing Regular Gum: Choose natural alternatives like mastic gum or organic chicle-based gums.

3. Say No to Takeout Packaging: Bring your own glass or stainless-steel containers for takeaway food and drinks.

4. Switch to Glass Bottles: Plastic bottles leach microplastics into water—choose glass whenever possible.

5. Vacuum & Dust Regularly: Reduce microplastic exposure at home by keeping surfaces clean and opting for natural fiber clothing and furniture.

6. Use a Water Filter: A high-quality filter can help remove microplastics from tap water.

7. Reconsider Your Dental Floss: Swap synthetic floss for natural silk floss or PFAS-free alternatives.

8. Which Textiles to Choose to Avoid Microplastics: Synthetic fabrics are a major source of microplastic pollution, as they shed tiny plastic fibers during washing. Recent studies have discovered microplastics in some of the most isolated areas of the world, including the Arctic and the protected Galapagos Islands. A 2014 study even found synthetic and semi-synthetic fibers, like Rayon, on the ocean floor. These tiny particles have been detected in the air, rivers, soil, drinking water, beer, and table salt. Microplastics are increasingly showing up in our food as well. Choosing natural textiles can significantly reduce your exposure. Here’s a quick guide: 

By opting for natural fibers, you reduce the amount of microplastics shed into the environment and minimize direct exposure through clothing—a true win-win situation!

Why We Choose Glass

At Dr. Garber’s bioformulas, we are committed to minimizing plastic exposure wherever possible. That’s why all our human and canine bioformulas are housed in glass bottles, ensuring purity and reducing the risk of plastic contamination. While our equine bioformulas are dispensed in plastic as a safety precaution for use in barns, we use bottles made from PETE ♳ which is the most recyclable plastic. We are committed to protecting the environment and your and your pet’s health and continuously explore sustainable alternatives.

Reducing your toxic load isn’t about perfection—it’s about making small, intentional choices every day. By being mindful of where microplastics hide, you can take steps toward a cleaner, healthier future for yourself and the planet.
