# Tablet Ingredient Notes > Malic acid occurs in fruit and shows up in chewables as a flavor and acidity ingredient. Here is what to know and what claims to question. ## Guides - [Where Malic Acid Occurs Naturally in Fruit](https://malic-acid-in-supplements.lebadume.workers.dev/malic-acid-in-strawberries-and-apples/): Malic acid is a fruit acid found naturally in many fruits, and malic acid in strawberries and apples is the example most often quoted. - [Acidic Ingredients and Tooth Enamel: A Fair Question](https://malic-acid-in-supplements.lebadume.workers.dev/malic-acid-tooth-enamel-acidity/): Asking whether acidic ingredients matter for teeth is a reasonable question. - [The Whitening Claim Attached to Malic Acid, Examined](https://malic-acid-in-supplements.lebadume.workers.dev/malic-acid-whitening-claim/): The malic acid whitening claim appears in some marketing, but a label listing a fruit acid does not show that a tablet changes tooth color. - [Do Acidic Chewables Need Special Care for Teeth?](https://malic-acid-in-supplements.lebadume.workers.dev/acidic-chewables-and-enamel/): Chewable products that contain food acids are not a reason for alarm, but they are worth a little thought. - [Common Food Acids You Will See on Labels](https://malic-acid-in-supplements.lebadume.workers.dev/food-acid-additives-on-labels/): Food acid additives on labels are ordinary ingredients used for tartness, flavor and keeping quality, and seeing one is not a warning sign by itself. ## About - [About Tablet Ingredient Notes](https://malic-acid-in-supplements.lebadume.workers.dev/about/): not medical advice, how the site is funded and how guides are made ## Optional - [RSS feed](https://malic-acid-in-supplements.lebadume.workers.dev/feed.xml)
