#TBHQ January 19

We may earn money or products from the companies mentioned in this post.

In January 2026, many of us will take part in the 30-Day Label Coach4aday Challenge. Each day we will share a label from a food product and share info about one of the ingredients. The goal is simple—read food labels, research unfamiliar ingredients, and become more intentional about what you’re putting into your body, building awareness that can lead to healthier, more mindful eating. Today my post is on TBHQ.

TBHQ (tert-butylhydroquinone) is a synthetic antioxidant preservative used in many processed foods and according to AI is an ingredient found in Butterfinger Candy Bars. It makes up less than 1% of total ingredients. The primary purpose of adding this to foods is to extend the shelf life.

Label-30 Day Challenge Guidelines

As with previous challenges, participants are encouraged to adapt the guidelines to fit their own circumstances. If you can, commit to sharing an ingredient from a food label during the month of January.

1. Locate a label on a food product and research an ingredient you might not be familiar with.  
2. Share with a challenge partner if you have one what that ingredient is.
3. Join the conversation by posting on social media with the hashtag #Coach4adayChallenge

Listed on the website EWQ was a listed of all the foods in 2019 that contained TBHQ. You can find that list at this link. The document is pretty extensive being 38 pages long with the Butterfinger being listed on page 26.
