Water Quality: How Safe Formulas Begin with Clean Water

Water Quality: How Safe Formulas Begin with Clean Water

Posted by Tori, MS, RDN, LD on Mar 6th 2023

Purity guides formula production here at Nature’s One and ensuring the water used is high quality is essential for all Baby’s Only® and PediaSmart® formulas.

With current events and issues impacting our environment, we understand why you may be concerned about the safety of your baby’s formula – especially as it relates to the safety of water used for formula production.

Nature’s One is committed to the purity of the nutritional products we create for your family, and this includes the purity of the water used while making Baby’s Only® and PediaSmart®.

Nature’s One ensures appropriate water quality in the production of all of its formulas.

Water is an important part of the powdered formula production process and, staying true to our commitment to purity, Nature’s One considers ensuring the use of clean water as a top priority.

Nature’s One is dedicated to purity and only the highest quality, purest water is tested, sourced, and used for formula production at the Nature’s One state-of-the-art facility.

Water sourced for formula production comes from a deep-water aquifer.

Nature’s One sources the water used for its formula production from a deep-water aquifer, which is 5000-feet deep. The water from this underground aquifer is filtered through two thick layers of bedrock. There are no surface water sources (from places like rivers and lakes) or exposure to runoff contamination at the Nature’s One facility.

Nature’s One relies on systems to purify water.

All water used to make the formula manufactured by Nature’s One is filtered with reverse osmosis membrane filtration. Reverse osmosis water filtration is an important, all-purpose preventative measure that Nature’s One relies on to control against many substances that may potentially contaminate water, such as mineral content and other material. Water is also purified with ultraviolet light, which acts a disinfectant to kill or deactivate viral, bacterial, or fungal species that may naturally be present.

We don’t just guess, we test. We’ve earned awards, too.

From start to finish, Nature’s One engages in rigorous testing programs. As part of the Nature’s One commitment to purity, Nature’s One regularly tests its water quality at independent labs to ensure the water we use is safe.

All Baby’s Only® Organic Infant and Toddler Formulas and PediaSmart® Organic Beverage Mixes have earned and continue to hold the Clean Label Project’s Purity Award. It’s our commitment to you that we take contaminants like heavy metals, plasticizers, and pesticide residues seriously.

We want to ensure that you use clean water, too.

It doesn’t end with us. Clean water is an important part of how you prepare your baby’s formula. We encourage you to ask your baby’s doctor about the best water for baby formula for your baby.

The CDC (Centers for Disease Control) recommends using water from a safe source to mix your formula. If you are unsure if your tap water is safe, contact your local health department.1

Ask your baby’s doctor about the need to use cooled, boiled water for mixing. If there are concerns over the tap water’s safety, you may need to use bottled water or cold tap water brought to a rolling boil for (no longer than) one minute, then cooled for no more than 30 minutes.2 If you plan to use the prepared formula right away, ensure that the formula is not too hot prior to feeding it to your child.

If your family uses well water, the American Academy of Pediatrics recommends that the well should be tested once a year for coliform bacteria and nitrates.3-4

You may use bottled water for formula preparation. As with tap water, ask your doctor about the need to use cooled, boiled water.5 In some cases, your doctor may recommend using bottled water that is labeled as purified, demineralized, deionized, or distilled.6
