Is it safe to drink bottled mineral water every day?
Not ideal. Mineral water in plastic carries both bisphenols and phthalates.
What's actually in it
Premium mineral water is usually packaged in the same PET plastic as regular bottled water. The difference is the source water and mineral profile, not the packaging. Bottles sit on warehouse shelves for months before reaching the shopper. During that time, the plastic slowly leaches bisphenols and phthalates into the water. Naturally carbonated mineral waters leach faster: the acidity and carbonation both speed migration.
A daily 500ml bottle looks benign. Over a year, that's 180 liters of water with a consistent plastic-contact history.
What the research says
A 2026 study in Environ Toxicol tested bisphenols and phthalates in bottled mineral water from the Brazilian market. Both chemical families showed up together, and the combined estrogenic activity was measurable. Regular consumers had an exposure level where the estrogenic and health risks weren't zero.
Glass-bottled mineral water (Gerolsteiner, San Pellegrino glass version, Perrier glass) handles the packaging side. Home sparkling water makers with CO2 canisters let you add bubbles to filtered tap water, which is the cheapest clean version. For a mineral boost without the bottle, a pinch of unrefined sea salt in a glass of filtered water adds trace minerals at a fraction of the cost.
