Water from glass bottles was recently shown to contain up to 3x more microplastics than plastic bottles. Concerning? Yes. But there's nuance. Size matters. The plastic particles from glass bottles were larger than those found in plastic bottles (micro- and nanoplastics). Larger particles are less likely to be absorbed by the gut and enter our circulation. I still think drinking from glass bottles is safer than drinking from plastic, especially because glass doesn't contain other chemicals like BPA and BPS. Ideally, you should drink filtered water from your own reusable (and BPA-free) bottle.
