Is Natural Flavors Vegan?
An evidence-backed guide to identifying natural flavors on a label.
Quick Verdict
The FDA allows "natural flavors" to be derived from both plant and animal sources. Without contacting the manufacturer, you cannot be 100% certain.
Common source: Plants (spices, fruits, vegetables) or animals (meat, seafood, poultry, eggs, dairy).
Confidence: Medium — verify the source on the label or with the manufacturer
What is Natural Flavors?
Flavoring substances extracted from natural sources through heating or roasting to enhance the taste of processed foods.
How Natural Flavors is made
A flavor house starts with a natural source — fruit, herb, spice, root, leaf, bark, or animal product — and extracts the volatile aromatic compounds using heat, fermentation, distillation, or solvent extraction. The result is a concentrated essence that is blended with other extracts to produce a final flavor profile. Because the FDA definition is purely about the source method (extraction from a "natural" raw material), the same chemical molecule can be labeled "natural flavor" or "artificial flavor" depending entirely on where it came from.
History and context
The "natural flavor" category was codified in the 1973 update to 21 CFR 101.22. It exists primarily as trade-secret protection for flavor houses, who don't want to disclose proprietary blends. The most cited animal-derived natural flavor is castoreum (from beaver castor sacs), though it is rarely used today due to high cost and ethical pressure.
Common misconceptions
"Natural flavors" sounds healthier than "artificial flavors" but the molecules can be chemically identical. The vegan question is purely about source, and most product categories — fruit drinks, soda, snacks — are statistically very likely to use plant-derived natural flavors.

Frequently asked questions
When should I worry about natural flavors?
In savory products — meat-, cheese-, or seafood-style flavorings are more likely to contain animal derivatives. In sweet or fruit-flavored products, the risk is very low.
Does "natural flavors" require an allergen warning?
Only for the FDA's big nine allergens (milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soy, sesame). Beef and chicken derivatives are not flagged unless the brand voluntarily discloses.
