In the United States, bottled water (including functional waters with added minerals) is regulated by the FDA under 21 CFR 165 and must meet safety limits similar to tap water. Common upper limits cited for bottled water include: Fluoride up to 2.4 mg/L. Heavy metals (EPA/MCLs): arsenic 10 μg/L (0.01 mg/L), lead 15 μg/L (0.015 mg/L), cadmium 5 μg/L (0.005 mg/L), mercury 2 μg/L (0.002 mg/L), chromium 100 μg/L (0.1 mg/L). Nitrates as NO3: 10 mg/L. These limits are enforced and product labels should reflect compliance; many brands publish batch test results or hold third-party certifications. If you’re aiming to minimize exposure, choose brands with public test data and prefer purified water. Safety note: If you have kidney disease, fluoride exposure concerns for children, or other health conditions, consult a clinician.

FDA regulates bottled water; fluoride usually capped near 1.4, 2.0 mg/L; heavy metals (arsenic, lead, mercury) kept at ppb. I choose NSF/USP-certified brands; check label; consult clinician if pregnant.

I choose brands that clearly list fluoride and contaminant testing; I avoid vague labels and switch brands if unsure.

FDA-regulated bottled waters in the U.S. must meet the same contaminant limits as tap water. Typical ceilings: fluoride up to about 4 mg/L; arsenic 10 µg/L; lead 15 µg/L; cadmium 5 µg/L; mercury 2 µg/L. Microbial limits aim for no detectable total coliforms in 100 mL. Always read the Certificate of Analysis or third‑party verifications. Safety disclaimer: if you have kidney, thyroid issues, or fluoride sensitivity, consult a clinician.
