Best Water for Baby Formula

You’re walking down the formula aisle and see (overpriced) nursery water and wonder “Is this the best water for my baby’s formula?” As if choosing a formula wasn’t complicated enough, now you must figure out what to mix with it. Formula is already so expensive, does the water need to be too?

While the best water for your baby formula depends on a few different factors, most of the time, you don’t need to pay a premium. No matter which water you choose, the Centers for Disease Control and Prevention recommend to mix powdered formula with hot water to kill a rare, but deadly bacteria that can be found in powdered formula (1).

Water Options

Tap Water

For many people, tap water should be fine. Check with your local health department to see if you should boil the water before making formula. If you need to boil it, you should do so for about a minute. More than that and you can increase the concentration of impurities in the water.

The American Dental Association recommends against extra fluoride in the water when mixing formula (which already contains fluoride). If your water is fluorinated, you may want to consider a low fluoride option. Once your baby is drinking plain water, the fluoride is perfectly safe.

Well Water

If you have a well, you will want to get it tested prior to using it for formula. You may need to boil the water or opt for an alternative.

Bottled Water

Standard Bottled Water

The bottled water that we usually drink can be used in a pinch, but often still has extra minerals in it. These minerals in and of themselves aren’t harmful, but your baby’s formula already has the ideal mineral content for your baby, there’s no reason to add any extra.

Distilled Bottled Water

Distilled bottle water will have the impurities and the minerals removed. It’s not great for drinking by itself, but it works well for mixing with formula. You can use tap water or a different water choice when you introduce plain drinking water to your baby.

Nursery Water

There’s nothing wrong with using nursery water, but generally, you’re just paying for the marketing. There’s no reason to pay extra for nursery water when another option will work just as well.

So which water is the best for your baby’s formula?

Tap water or plain distilled water tends to be the best water for baby formula. Both are relatively inexpensive and should be safe to use (check your local health department for the status of your tap water).
