What did the 2024 study actually find?
A study published in the New England Journal of Medicine in 2024 examined plaque removed from the carotid arteries of patients. In roughly half the samples, researchers detected micro- and nanoplastics such as polyethylene. Over about three years of follow-up, patients with plastics in their plaque had a higher rate of a combined outcome of heart attack, stroke, or death than those without. The authors were careful to note the limits: this is an observational finding. It cannot prove the plastics caused the events, other factors could be involved, and it doesn’t yet tell us whether reducing exposure changes outcomes. It’s a signal worth taking seriously, not a settled conclusion.Why might plastics matter for blood vessels?
The leading hypothesis is inflammation. Foreign particles lodged in tissue can trigger low-grade inflammatory responses, and inflammation is already understood to play a role in atherosclerosis (plaque buildup). Some plastics also carry chemical additives — such as certain phthalates and bisphenols — that can act as endocrine disruptors. All of this is under active study and not yet conclusive for microplastics specifically.How do microplastics get into the bloodstream?
We take particles in mainly through food, water, and air. From the gut and lungs, the smallest particles (nanoplastics) may cross into circulation. This is why cutting exposure at the source is the most evidence-backed step — see how microplastics get into the body and are microplastics harmful?.What can you actually do?
The strongest levers are about reducing new exposure and supporting overall heart health:- Choose glass or stainless steel over plastic for food and drinks, and don’t microwave food in plastic. See microplastics in food.
- Filter tap water and skip single-use plastic bottles. See reduce microplastics in drinking water.
- Keep up the basics that protect your heart: not smoking, staying active, managing blood pressure and cholesterol, and eating fiber-rich whole foods.
- Stay hydrated to support your body’s normal elimination pathways.
Where does a detox supplement fit?
Your body already has natural elimination pathways. Gut-level binders like clinoptilolite zeolite are used to support those pathways — not to “remove” plastics from your blood vessels, which no supplement does. Plastiq Off offers that kind of gentle daily support (zeolite + active B12) alongside the exposure-reduction and heart-health habits above, which do the real work. For any cardiovascular concern, see your clinician.Related: Are Microplastics Harmful? · Microplastics and the Brain · Microplastics and Gut Health · How to Reduce Microplastics · Buy Plastiq Off
