Health experts are warning the public about a potential risk hidden in a common type of supplement: soft-gel capsules. As people turn to vitamins to fend off seasonal illnesses, researchers are raising concerns about the chemicals used to make these squishy pills.
Soft-gels contain plasticizers, typically phthalates, which keep the gelatin shell flexible. Phthalates are known endocrine disruptors, meaning they can interfere with the body's hormone systems. Studies have linked them to a range of health issues, including reproductive problems, developmental defects in children, allergies, and an increased risk of cardiovascular disease.
While phthalates in medicines are regulated, over-the-counter supplements operate with less oversight, making it easier to unknowingly exceed safe exposure levels. Experts note that supplements are not the primary source of phthalate exposure—common items like vinyl flooring, perfumes, and plastics contribute more significantly. However, for individuals taking multiple soft-gel supplements daily, the added exposure is a growing concern.
Cardiologist Dr. Evan Levine emphasizes that phthalates can increase inflammation, a key risk factor for heart disease. Craig Russell, a pharmacy lecturer, adds that assessing the danger is complex due to the many types of phthalates, but cautions that long-term exposure is particularly risky for vulnerable groups like children and pregnant women.
This alert follows broader warnings about supplement safety, including the dangers of overdosing on common vitamins like Vitamin D, which can damage kidneys and the heart. The key takeaway: know what you're consuming, and consult a healthcare professional before starting any new supplement regimen.
