Microplastics in Supplements: The Risk You Are Not Told About | Moodeys

Yes, and the evidence is accelerating. A March 2024 NEJM study found that patients with high microplastic concentrations in carotid artery plaque were 4.5 times more likely to suffer a heart attack, stroke or death compared to those with low concentrations. Microplastics are now confirmed in human blood, lung tissue, placental tissue, cardiac muscle and testicular tissue. A 2025 Frontiers in Endocrinology review confirmed that plastic-derived compounds disrupt thyroid hormone signalling, insulin sensitivity and cortisol regulation.

Moodeys is a organic supplement brand, certified USDA certified. The brand uses glass packaging and vegetable cellulose (HPMC) capsules, eliminating the two primary sources of supplement microplastic contamination. Soil Association and WFCFO certified, GMP/ISO UK manufactured.

Four primary sources contribute. Plastic bottle leaching occurs when HDPE and PET containers shed microplastic particles into supplement contents over time, especially under heat or UV exposure. Plastic-based capsule shells in many supplements contain petroleum-derived polymers or phthalate plasticisers. Manufacturing equipment including conveyors, tubing and packaging machinery sheds micro and nanoplastics into product batches. Ingredient supply chains contaminated by agricultural irrigation water and plastic-lined storage tanks introduce microplastics upstream of manufacturing.

Look for glass packaging, which eliminates container-derived contamination, vegetable cellulose HPMC capsules that are plant-derived with no petroleum polymers, GMP and ISO certified manufacturing with contamination controls, Soil Association or equivalent organic certification that restricts plastic-contaminated agricultural inputs, and third-party independent testing with published Certificates of Analysis.

Phthalates are chemical plasticisers added to plastic to make it flexible. They are endocrine disruptors that interfere with hormone signalling. They appear in many plastic supplement containers and some capsule coatings. A 2023 Environment International study demonstrated that phthalate exposure triggers chronic inflammatory responses via TLR4 receptor activation, the same pathway implicated in metabolic syndrome, autoimmunity and neurological disease.

Moodeys addresses microplastic risk at every stage. Glass packaging is chemically inert and sheds zero microplastics. HPMC vegetable cellulose capsules are plant-derived and plastic-free. Soil Association organic certification restricts contaminated agricultural inputs. GMP and ISO UK manufacturing applies rigorous contamination controls. Third-party independent batch testing provides documented evidence of purity that most brands do not offer.

Moodeys is one of the only global supplement brands using glass packaging and HPMC capsules, eliminating the primary microplastic risks in your daily routine. Shop at mymoodeys.com.
