Also known as 4-hydroxy-3-methoxy cinnamic acid. Ferulic acid is a polyphenolic constituent of plant cell walls. It’s abundant in whole grains, fruits and some vegetables. It’s a potent antioxidant in-vitro, although its dietary bioavailability may be limited. Ferulic acid and its derivatives have potential therapeutic applications against diseases such as cancer and diabetes, but human clinical trials are lacking.
Ferulic acid is also used as a “cosmeceutical”, as it can help protect skin against UV-induced damage.
Ferulic acid may also be written as “trans-ferulic acid” as the trans isomer is the dominant natural form.
