Is Peanut Butter Gluten-Free?

peanut butter gluten free

Peanut butter is a classic comfort food. It tastes great on oat bars, on toast, in smoothies, in yogurt and oatmeal, on fruit and more. But you may be wondering, “is peanut butter gluten-free?” 

Peanuts are naturally gluten-free, but does peanut butter have gluten? That will depend on the brand you are getting at the grocery store, if you’re not crushing the nuts yourself. 

Peanut butter products that are processed and bought in a container may have cross-contamination with gluten-containing ingredients as well as other flavor additives, which can be problematic for those with a gluten allergy or sensitivity. 

The safest bet is to grind it yourself or get peanut butter that is plain and raw, with a minimal ingredient list and that says “gluten-free” on the label. Here’s what to know when you’re picking out your peanut butter of choice at the store: 

Does peanut butter have gluten?

Peanuts in their natural state - raw and unflavored - will be free of gluten, in both nut and nut butter form. But some additives and preservatives that are used in the processing or flavoring of peanuts may contain gluten, which might make them off limits for gluten-intolerant individuals. 

If you are eating plain, raw and salted or unsalted peanut butter you should be okay. However, if you’re eating honey mustard glazed peanut butter, then there is likely gluten in this flavored option. If the peanut butter includes extra ingredients, like wasabi, it may be tricky to guarantee whether or not the peanut butter is gluten-free.

Here is a handy list of terms to watch out for on peanut butter labels. Before buying, you should always read the labels to look for where it says “gluten-free” and check for any of these ingredients—these are red flags! Plus if it says, “May contain wheat or gluten,” on the label, then you know it’s also a risk.

You can also look to third-party gluten-free labels or reach out to the brands themselves to inquire before purchasing. Choosing gluten-free peanut butter will get easier with time, and you’ll soon find the brand options that you love and can stick with long-term.
