All baby formulas tested are safe, but about half had arsenic above Consumer Reports' stricter limit
Do this instead
- Don't switch formulas without talking to your doctorEspecially for babies with allergies or medical needs.
- Ask about alternatives to soy or plant-based formulaAll five plant-based formulas tested had higher arsenic.
- Mix powder with clean waterIf you're on a well, test it for heavy metals.
The short version
Consumer Reports tested 49 infant formulas in March 2026 and stresses that all of them are safe to feed your baby. About half had inorganic arsenic at or above a new, stricter level of concern, and three powdered formulas were above its lead limit. Soy and plant-based formulas had the most arsenic. Never make homemade formula.
The evidence
26 of 49 formulas had inorganic arsenic at or above Consumer Reports' new level of concern, which it lowered after the US EPA tightened its own guidance. All five soy or plant-based formulas were in that group. Organic formulas were generally low.[1]
Three powdered formulas were above Consumer Reports' level of concern for lead. Cadmium and mercury weren't flagged. Consumer Reports' full results list which formulas scored best and worst.[1]
