Beta-carotene is a naturally occurring pigment found in fruits and vegetables, particularly those that are orange or yellow in color. It is a precursor to vitamin A, meaning the body converts it into vitamin A as needed.

This biomarker is crucial for assessing nutritional status, especially in individuals with diets low in vitamin A-rich foods. It also serves as an indicator of antioxidant levels in the body.

Low levels of beta-carotene may indicate malnutrition or malabsorption issues, while high levels can suggest excessive supplementation or a diet rich in carotenoid-containing foods.
