Natural flavors sound healthy, but they may include hidden additives and animal products. Here’s what they are, how they’re made, and how to avoid them.
Ever wonder what “natural flavors” are and why they show up on so many food labels? They sound innocent—maybe even wholesome—but the truth is far less clear-cut. These lab-created flavor concentrates are legally derived from plant or animal sources, but often contain dozens of undisclosed ingredients. If you’re avoiding allergens, animal products, or just want more transparency, it’s time to look closer at what “natural flavor” really means.
Why I Stopped Buying Products With “Natural Flavors”
I used to love a particular vanilla plant-based milk. Just three ingredients: water, oats (or nuts), and “natural vanilla flavor.” It made my morning coffee taste amazing. Then I emailed the company and asked a simple question: “What’s actually in your natural flavor, I’d like to know the ingredients?” They responded with, “It’s proprietary.” That told me everything I needed to know. If it were just vanilla bean and lemon peel, they’d proudly say so. That was the day I started removing “natural flavors” from my cart—and the inspiration behind this post.

The Legal Definition (U.S.) in Plain English
Under FDA rules, a “natural flavor” must derive its flavor components from natural sources—fruits, vegetables, herbs, meat, seafood, dairy, eggs, or fermentation byproducts. But that’s just the start. These flavorings can then be processed using high-heat, solvents, enzymes, fermentation, and other methods. What’s more concerning: the law allows “incidental additives” (like propylene glycol, glycerin, BHA, and emulsifiers) to be included without being individually listed.
Natural vs. Artificial Flavors
Both are made in labs. The only difference is the starting point:
- Natural flavor starts from a plant or animal.
- Artificial flavor starts from a synthetic compound.
Either can contain dozens of chemicals used to preserve, carry, or enhance the flavor. “Natural” doesn’t mean simpler or safer.
What Can Be Inside a “Natural Flavor”?
Here’s what may be hiding inside:
- Essential oils
- Enzyme-modified extracts
- Oleoresins
- Fermentation byproducts
- Animal extracts
- Solvents (propylene glycol)
- Preservatives (BHA)
- Emulsifiers and carriers
All of this can legally be labeled under one tidy phrase: natural flavor.
Pet Food Implications
In pet food, “natural flavor” often comes from hydrolyzed animal proteins or yeast extracts. If your pet has food sensitivities or dietary restrictions, ask the manufacturer directly about the source—or better yet, make your own dog food using whole, simple ingredients. I’ve created a lot of healthy dog food recipes. You can find them all on our website.

Clean Label Strategies: How to Avoid Hidden “Natural Flavors”
Want to keep your pantry real and transparent? Try these:
- Choose products with real ingredients listed by name
- Buy unflavored versions and flavor them yourself
- Contact brands and ask for full disclosure
- Opt for short, understandable ingredient lists
- Make more meals and snacks at home
- Use herbs, spices, citrus zest, or vanilla extract for flavor
- Write your congressional representatives and senators to demand clearer labeling laws
Are Natural Flavors “Bad”—Or Just Opaque?
They’re not always harmful—but they are often undisclosed, and that’s the real issue. Without full transparency, we’re left guessing. And we deserve better than that.
Label-Reading Mini Checklist
- Natural flavor listed with no detail? ➤ Ask the brand
- Long list of additives? ➤ Likely ultra-processed
- Vegan/kosher label? ➤ Still confirm with the company
- Pet food? ➤ Ask what the protein source is
How to Ask a Company

You may or may not want to contact a company. If not, you may want to consume products without “natural flavors”.
