Who Makes Kirkland Formula

Do you know who makes Kirkland Infant Formula? this is one of the questions our readers ask a lot. Well, we´ve got you covered.

If you are a Costco shopper, you have probably come across a ton of products with the Kirkland name; that is because Kirkland is a Costco label that is used for marketing Costco products under a private name.

So, who makes Kirkland Formula? Kirkland formula is manufactured and shipped through Perrigo. Perrigo is a 3rd party medical supply and manufacturing company that complies with all FDA requirements, SQF codes and is ISO certified. Meaning it follows all the U.S requirements for safe and healthy formulas.

Although there is a negative stigma around store-brand or “off-brand” formulas, it is essential to look into the details and ingredients before spending more money on a name.

Here is all the information you need on the manufacturing of Kirkland formula and why it is just as good as the rest.

Who Makes Kirkland Formula?

Before we can get into who makes the baby formula, let’s quickly discuss who Kirkland is. Kirkland or “Kirkland Signature” is Costco’s private label and is used on manufactured Costco items to give the public a sense of security when purchasing store-brand items.

Costco didn’t want parents to feel their formula (or any product) was “less than” the name brand formulas, or were not as nutritional because of the lower price, so they came with the Kirkland name.

Now, they just needed someone to manufacture the formula; and that is where Perrigo comes into play.

Who is Perrigo

Perrigo is a health care supplier for places all over the world.

The company originated in 1887 by founder Luther Perrigo, where his main objective has always been manufacturing and supplying healthcare and nutritional products at affordable prices.

Not too long ago, Kirkland formula was actually manufactured by Similac but has changed hands in recent years.

This change didn’t lead to much of a difference in the product’s ingredients, manufacturing, or price. 

Nutritional Facts

To get a good understanding of just how similar Kirkland’s formula is to name brand items, let us take a look at Kirkland and Similac Ingredients side-by-side.

To make it easier, we highlighted the ingredients that had were not exactly the same. As you can see, there are not many, and the ones that are different only differ by a tiny amount.
