Carotenoids are a class of over 600 naturally occurring pigments found in a variety of plants, algae, and photosynthetic bacteria. They are responsible for the bright red, yellow, and orange hues of many fruits, vegetables, and flowers.

The best-known carotenoids include beta-carotene, lutein, zeaxanthin, and lycopene. These fat-soluble compounds play an essential role in light absorption during photosynthesis and protect plants from the harmful effects of light.

In human nutrition, carotenoids have a dual function: first, they serve as precursors of vitamin A, an essential nutrient important for vision, immune function, and skin health. Second, they act as powerful antioxidants, protecting the body from the harmful effects of free radicals, which can lead to chronic diseases and premature aging.

Integrating carotenoids into dietary supplements provides a targeted way to support the intake of these important micronutrients, especially when the diet is not rich enough in carotenoid-containing foods.

Adequate intake of carotenoids is crucial for maintaining health and preventing diseases, including possibly reducing the risk of certain cancers, eye diseases, and cardiovascular diseases.
