vegetable oil + beta-carotene

This is a **combination product** in which **beta-carotene**, a carotenoid and provitamin A, is dispersed in an edible **vegetable oil** (typically non-petroleum derived). Beta-carotene acts as an antioxidant and is a precursor to vitamin A. The oil serves as a lipid carrier that improves the stability, solubility, and oral bioavailability of beta-carotene, which is fat-soluble. Commonly used vegetable oils include corn oil, red palm oil, and others, with beta-carotene being naturally present or added at concentrations typically ranging from 0.5 to 7.5% by weight. Such compositions are used primarily as dietary supplements for **antioxidant support** or **vitamin A supplementation**. The mechanism of action is mainly antioxidant, as both beta-carotene and vegetable oils contain antioxidant compounds (such as tocopherols, i.e., vitamin E) that help neutralize reactive oxygen species and prevent oxidative damage to cells[1][2][3][4].
