Scientists estimate that the average adult ingests the equivalent of one credit card worth of plastic every single week. That is not a headline designed to shock you — it is a finding from peer-reviewed research that has been replicated multiple times. Microplastics in your body are not a future concern. They are here right now.
A brand new Netflix documentary called The Plastic Detox released in March 2026 has brought this issue to millions of people simultaneously — and searches for how to detox from microplastics have exploded overnight. But what does the science actually say? And what can you realistically do about it?
In this guide we break down exactly what microplastics in your body are doing to your health, where they come from, and the evidence-backed natural strategies to reduce your exposure and support your body’s natural detoxification — starting today.
What Are Microplastics — And Where Are They Coming From?
Microplastics are plastic particles measuring less than 5mm in size — some are visible to the naked eye, many are not. Nanoplastics are even smaller fragments less than 1 micrometer — invisible and far more concerning because they penetrate biological barriers more easily.
They enter your body through three primary routes: ingestion (eating and drinking), inhalation (breathing), and skin absorption. They come from sources most people never think about:
- Plastic water bottles — especially when exposed to heat or sunlight
- Food packaging — particularly anything stored or heated in plastic containers
- Tea bags — a single plastic-based tea bag releases billions of particles into hot water
- Disposable coffee cups — the plastic lining breaks down in hot liquid
- Synthetic clothing — polyester and nylon shed microplastic fibres with every wash
- Plastic cutting boards — cutting on plastic generates tiny shavings that mix into food
- Tap water and bottled water — microplastics have been found in both globally
- Sea salt, honey, beer — virtually all tested food products contain microplastic particles
- Indoor air — synthetic carpets, furniture and insulation shed particles you breathe constantly
Microplastics have been detected throughout the entire human body — in the placenta, breast milk, lung, intestine, liver, kidney, heart and cardiovascular system, blood, urine, and cerebrovascular tissue. They have even been identified in uterine and testicular tissue. — PMC Research 2024.
What Are Microplastics in Your Body Actually Doing to Your Health?
The honest scientific answer is that research is still emerging — but what we already know is deeply concerning. Microplastics cause harm through two mechanisms: direct physical damage to tissues, and chemical leaching of the toxic compounds they contain.
Hormonal disruption — the most alarming effect
Microplastics contain chemicals like BPA (bisphenol A), phthalates, and PFAS — so-called forever chemicals. These compounds are endocrine disruptors — meaning they mimic human hormones and interfere with the body’s hormonal messaging system. The effects include reduced fertility in men and women, disrupted menstrual cycles, thyroid dysfunction, and metabolic disorders including insulin resistance.
Research found that chemicals like BPA and phthalates can mimic human hormones controlling reproduction, growth and metabolism. Exposure has been shown to increase the risk of infertility, poorer fetal development, and cancer. — UCSF Microplastics Research, 2026
Inflammation and immune disruption
Microplastics trigger chronic low-grade inflammation — the same underlying mechanism behind heart disease, diabetes, cancer, and accelerated skin ageing. Animal and cellular studies have linked microplastics to impaired immune function, deteriorated tissue integrity, and altered metabolic function.
Gut health damage
Microplastics accumulate in the gut lining and disrupt the microbiome — the community of beneficial bacteria essential for immunity, mood, and overall health. Research has found a correlation between microplastic concentration in fecal matter and inflammatory bowel disease. Your gut health is directly affected by your plastic exposure.
Cardiovascular risk
In a concerning finding, microplastics have been detected in 80% of analysed blood clots — suggesting a potential link between plastic accumulation in the cardiovascular system and increased clotting risk. This is one of the newest areas of microplastics research and the implications are significant.
Reproductive health
The Netflix documentary The Plastic Detox followed six couples with unexplained infertility through a 12-week plastic elimination experiment. By the end, couples showed substantial declines in BPA and phthalate levels in their urine — and three of the six couples became pregnant. While this was a small preliminary study, it reflects the growing scientific concern about plastic chemicals and reproductive health.
How to Detox Microplastics from Your Body — Natural Strategies
Complete elimination of microplastics from your body is not currently possible — there are no established clinical protocols for removing them from tissues. However, you can significantly reduce your ongoing exposure and support your body’s natural detoxification pathways.
1. Switch to filtered water immediately
Plastic water bottles are the single largest source of daily microplastic ingestion. A quality water filter combined with glass or stainless steel containers is the most impactful single change you can make.

2. Never heat food in plastic
Heat dramatically accelerates the leaching of plastic chemicals. Microwaving food in plastic containers releases up to 2.1 billion microplastic fragments per square centimetre in just 3 minutes. Always transfer food to glass or ceramic before heating — this single habit eliminates one of your biggest daily exposure sources.

3. Eat high-fibre foods daily
Dietary fibre helps bind microplastics in the gut and facilitates their excretion. Research suggests that a high-fibre diet supports the gut microbiome in processing and eliminating microplastic particles more efficiently. Aim for 25–35g of fibre daily from vegetables, legumes, oats, and flaxseeds.
4. Add chlorella to your routine
Chlorella — a green algae supplement — is one of the most studied natural binders of environmental toxins. Its cell wall structure binds to heavy metals and potentially microplastic-associated chemicals in the gut before they are absorbed. Used in detoxification protocols for decades, it is safe, affordable, and widely available.
Recommended: Chlorella powder or tablets [SHOP NOW] — take daily with water before meals for best binding effect
5. Sweat regularly — exercise and sauna
Sweating is one of the body’s natural detoxification channels. Regular exercise that induces sweating helps your body excrete accumulated toxins through the skin. Infrared sauna use has gained significant research interest as a method for eliminating stored environmental toxins — including chemicals associated with microplastics — through sweat.
6. Eat antioxidant-rich foods
Microplastics cause oxidative stress — free radical damage to cells and tissues. A diet rich in antioxidants directly counteracts this damage. Focus on berries, green tea, broccoli, dark leafy greens, dark chocolate, and tomatoes daily. These foods support your body’s natural defence against the cellular damage microplastics cause.
7. Replace plastic cookware and utensils
Plastic cutting boards, non-stick pans with scratched coatings, and plastic utensils all shed microplastics into food during cooking. Replace with wood cutting boards, stainless steel or cast iron pans, and wooden or silicone utensils. These swaps are one-time purchases that eliminate ongoing daily exposure.
8. Choose natural fabrics
Synthetic fabrics like polyester and nylon shed millions of microplastic fibres with every wash — which enter the water supply and your home air. Choose natural fabrics like cotton, linen, wool, and bamboo where possible. When washing synthetics, use a microfibre filter bag in your washing machine to capture shed fibres.
Frequently Asked Questions
Can you completely detox microplastics from your body?
Not currently — there are no established clinical methods for removing microplastics that have already accumulated in body tissues. However, significantly reducing your ongoing exposure combined with supporting your body’s natural detox pathways (fibre, sweating, antioxidants, chlorella) can meaningfully reduce your microplastic burden over time. Focus on reduction rather than elimination.
Are microplastics in bottled water worse than tap water?
Both contain microplastics — research has found microplastics in virtually every water source tested globally. However, plastic water bottles — especially when exposed to heat, sunlight, or repeatedly reused — release significantly more plastic particles than tap water. Filtered tap water in a glass or stainless steel container is consistently the lowest-microplastic option available.
Do microplastics affect skin health?
Yes — through two mechanisms. First, microplastics inhaled or ingested accumulate in tissues and trigger systemic inflammation which manifests on the skin as acne, redness, and accelerated ageing. Second, some microplastics are found in cosmetics and personal care products as microbeads, entering through skin contact. Choosing clean beauty products free from microbeads directly reduces this exposure route.
Is the Netflix Plastic Detox documentary accurate?
The documentary is based on real research and features credible scientists including Dr Shanna Swan, a leading environmental reproductive epidemiologist. The preliminary study shown is not a full clinical trial, and scientists are careful not to overstate conclusions. However, the broader scientific concern about microplastics and hormonal health is well established in the peer-reviewed literature — the documentary reflects genuine scientific concern, not fearmongering.
What foods have the most microplastics?
Based on current research, the highest microplastic concentrations are found in bottled water, seafood (particularly shellfish which filter-feed from contaminated water), sea salt, canned foods (from the lining), and foods heated or stored in plastic packaging. Choosing fresh, unpackaged foods, filtering your water, and avoiding plastic food storage significantly reduces your dietary microplastic intake.
Can children be affected by microplastics?
Yes — and research suggests children may be more vulnerable than adults due to their developing hormonal and immune systems. Microplastics have been found in meconium (a newborn’s first stool) and breast milk, indicating that exposure begins before birth. Prioritising glass or stainless steel feeding equipment, natural fabric clothing, and filtered water for children is especially important.
Final Thoughts — Small Changes, Big Difference
Microplastics in your body are an unavoidable reality of modern life — but that does not mean you are powerless. The science consistently shows that reducing exposure produces measurable reductions in the toxic chemicals microplastics carry, with potential benefits for hormonal health, fertility, gut health, and long-term wellbeing.
You do not need to overhaul your entire life overnight. Start with the two highest-impact changes — switch to filtered water in a glass bottle and stop heating food in plastic. These two habits alone eliminate a significant proportion of your daily microplastic intake. Then gradually add the other strategies over the coming weeks.
Every swap you make is a meaningful step toward a lower toxic burden — for you and for your family. 🌿
