Tap Water For Baby Formula

November 13, 2020

As carefully as you selected your 100% organic baby formula to provide the best nutrition for your infant, you also need to be very selective of the water that goes into it.

Not All Tap Water Is Safe for Making Baby Bottles

While all types of tap water may appear to be the same, it can vary greatly. Depending on the source, each kind of water has its own benefits and drawbacks.

There are some water types that you must avoid in baby formula preparation. You need to look for impurities that can be found in the water supply before you use it for baby formula.

To prepare powdered baby formula the water should be low in sodium, nitrate, nitrite, fluoride, sulfates, and manganese. Babies should be provided with water that is clean, healthy and overall relatively low in mineral content.

Tap water safety varies greatly from city to city. To check your local water, visit your water municipality’s website. All municipalities are required to publish an annual water quality consumer confidence report. If all is not well with your city water, the consumer confidence report will tell you.

Even if everything checks out with your city water, you still have the possibility of contaminants that might be coming into your home from the pipes. It is best to take every precaution to ensure your baby will not receive harmful additives.

Boiling For Safety

In order to kill any germs, bacteria, or viruses we recommend always boiling tap water when making your baby's formula. To make sure the water is sterilized, mix the formula 30 minutes after the water is boiled and before it cools below 158° F.

A Word on Fluoride

To help prevent cavities, more than 60% of the U.S. population receives fluoridated water through their tap. Some communities have naturally occurring fluoride in their water, but the majority receive it as an additive.

Although there is some degree of benefit when it comes to the adult population, fluoride can have negative effects on your infant.

There are many concerns when it comes to using water with heavy concentrations of fluoride present for babies:

  • High levels of this fluoride in baby formula preparation can cause enamel or dental fluorosis
  • Fluoride can cause permanent discoloration on your baby’s developing teeth
  • Very rarely, fluoride poisoning can happen if large amounts of fluoride is ingested during a short period of time

If you have no choice but to use fluoridated water, check with your local water company and make sure that the levels of fluoride present in the water is less than 0.7 mg per liter.

Low fluoride tap water might be labeled as “demineralized,” “purified,” “distilled,” or “deionized.”

Excellent product

We are very happy with the LouLouka formula. We supplement breastmilk with formula when my supply is low. Our son, who is 8 months old, loves the taste and digests it very well. We rarely get a spit up after drinking a bottle of this. I really like that I can trust the ingredients in this formula to be organic and high quality. I also like that it includes DHA in its contents.

Great formula

Baby loves it and have no issues with spit up or refusing the bottle.


This formula seriously saved us… My son is a reflux baby and throws up constantly all day. We tried the Enfamil gentle ease as well as another organics brand and neither seemed to help. We got him on an infant probiotic and this formula and he is a completely different baby! He still has spit up don’t get me wrong but his body does so much better with this! So thankful!

Our son seems like he feels good finally!

Our son has been way less fussy and actually enjoys this formula! Way less spit up and a happier baby! If your doctor recommends mixing it with breast milk (if your baby is trying to gain weight like ours needed to) use WAY less formula in the breast milk bottle otherwise it will not be able to get through the bottle lol and it will be harder for baby to process. But if you're just using water then the 1 scoop per oz seems to be just right.
After so much trouble with American made formulas, we're so happy we found HiPP and to see our son feeling better.

He does seem hungrier faster with it, BUT he is also growing a lot and he's always been a hungry baby lol. So worth it to see how much better he feels! He is 5 weeks now and 1 box lasted us about 2 weeks. He just started averaging about 3.5-4oz each feed & that's usually even after breastfeeding. Like I said..hungry little guy lol

Great Customer Service
