Bioavailability of Carotenoids from Vegetables versus Supplements

Carotenoids are the widely distributed, naturally occurring pigments responsible for the yellow, orange, and red colors of fruits, roots, flowers, fish, invertebrates, and birds. They also occur in algae, bacteria, molds, and yeast. In higher plants, they occur in the photosynthetic tissue, the choloroplast, where their color is masked by that of the more predominant green chlorophyll.
