Are natural flavors gluten-free?
Natural flavors are usually gluten-free. Under US FALCPA, any wheat used in natural flavors must be disclosed on the label. Barley and rye are not required disclosures, so celiacs who want certainty should look for a gluten-free claim on the final product.
When it's safe
- The allergen line does not mention wheat
- The product carries a gluten-free certification or claim
- The flavoring is on common safe lists (vanilla, citrus, most herb/spice extracts)
When to avoid it
- The product contains "natural flavor" plus "malt" or "malt flavoring" (malt = barley)
- The product is a beer, whisky, or malted beverage — barley-derived flavors are common

Do natural flavors contain gluten?
Rarely. In the US, fewer than 1% of products with "natural flavors" use gluten-containing ingredients, and if wheat is used it must be disclosed. Barley is a slightly bigger risk in malted products and craft sodas.
Are natural flavors in yogurt gluten-free?
Almost always. Major yogurt brands using natural flavors (Chobani, Fage, Dannon, Oikos) produce gluten-free products; check the label for a "gluten-free" claim.
