Why does formula get foamy?

July 14, 2020 2 min read

Oftentimes formulas will have bubbles and foam. But is this a bad thing? Too much foam can be bad and mothers may be wary if they see this.

Typically, processed American formulas will have too much foam, causing digestion issues in babies. Why is this? Simply put, the bubbles in formula are air, and the additional air can hinder your child's digestion.

Why is formula foamy?

The reason why formulas contain foam lies in the making process. When you mix the powder with water and shake—you can end up with too much foam.

Let’s face it though, some formulas foam up more than other brands.

The quality of the formula has a major impact on this as higher quality formulas do not produce excessive foam.

For example, Kendamil’s high quality ingredients include whole milk and no palm oil, giving parents a less foamy formula that baby is able to digest easily.

This can be a lifesaver when digestion issues arise, making infants lose sleep and face discomfort.

What do I do if my formula is foamy?

If your baby is facing tummy troubles due to foam, you need to know how to get rid of foam in formula. Follow the protocol below:

  • Scoop out the foam.
  • Add 1-2 drops of natural or doctor prescribed gas drops.
  • Mix formulas with heated water that has cooled, and then warm up bottle.
  • Stir instead of shaking to reduce the amount of foam.
  • Make bigger batches to reduce the amount of foam. Batches last 24 hours, so you can make a day's worth of formula using this method.


Foam can cause disrupted digestion and further complications in infant health. When in doubt, choose a higher quality formula. If unable to do so, you can try the methods listed above to reduce the amount of foam. Overall, we recommend a combination of both to ensure the best for your child.

Transitioning from breastmilk to kendamil

So far it's been great my LO has a very sensitive stomach and she seems to throughly enjoy it as much as breastmilk. The best ingredients I've come across so far had to do a little bit of research before hand... also pretty fast shipping is always a plus!

Awesome formula

I like that this formula doesn’t have bubbles after shaking

Love this formula. Pricey but 100% worth it for my LO.

Favorite formula.

The best formula out there.

Amazing formula

My baby is doing so much better on this formula. The other one made him super gassy and constipated. He wanted to eat all the time. With in the first bottle he was calm and satisfied. I feel he is getting what he needs.
