What Is LIMONENE?

Supplement

D-Limonene is a naturally occurring monoterpene found primarily in citrus fruit peels, particularly oranges, where it comprises up to 90% of the essential oil content. It acts as a 5-HT1A receptor agonist, demonstrates anti-inflammatory and antioxidant properties, and functions by improving gastric motility and protecting the esophageal lining. Primarily used for treating gastroesophageal reflux disease (GERD), it also shows promise for mood enhancement, anxiety reduction, and various therapeutic applications including antibacterial and anticancer effects.
