Carotenoids, pigments widely distributed in the natural world, are predominantly found in plants and animals. They serve as essential molecules vital for various life processes and metabolic activities. In plants, carotenoids impart vibrant colours to fruits and flowers, contributing to their visual appeal. Carotenoids must be consumed through food or supplementation because people cannot produce carotenoids in their bodies. Carotenoids contribute significantly to human health by primarily serving as antioxidants, yet various carotenoids possess distinct and unique functions. For instance, β-carotene acts as a precursor to vitamin A, while lutein and zeaxanthin form the macular pigment crucial for eye health. The biological properties of carotenoids enable a variety of commercial uses. The primary cause for the recent attention towards carotenoids stems from their possible application as potential and promising nutraceuticals. Studies have demonstrated that carotenoids offer benefits for cardiovascular health, cognitive function, and potential cancer prevention and notably support eye health. Additionally, their colour-imparting abilities have led to historical use in both food and animal feed. Scientific research studies confirm these health advantages and have led to a rapid expansion in their application in managing and treating human metabolic diseases.
