Phthalates

Key Takeaways
- Phthalates are a class of compounds used in plastics, fragrances, food packaging, personal care products, and more.
- They can leach into the environment and our bodies, acting as endocrine disruptors and increasing the risk of reproductive problems, obesity, asthma, ADHD, and even increased mortality from cardiovascular disease.
- Phthalates are pervasive in our food supply, from packaging to processing equipment. Studies show that almost all of us have phthalates in our bodies.
- The body metabolizes phthalates quickly, excreting them in urine, sweat, and feces. Understanding the role that your genetic variants play in phthalate detoxification can help you eliminate them more efficiently.
