The absorption and deposition of carotenoids added to poultry diets into the yolk of eggs produced by the poultry is improved by adding a carotenoid formulation comprising a carotenoid, a vegetable oil, a surfactant, a chelating agent, an antioxidant, an alkali and a solvent. The carotenoid formulation can reduce the crystalline nature of lutein for its better dissolution in the formulation and the diet. This new formulation is capable of making more micelles for an effective transfer of lutein from the formulations to the aqueous layer. The new formulation can increase the bioavailability of lutein in chicken biological system and leads to more deposition in the blood and the egg. The lutein deposition in the egg was consistent for an extended period of time when this new formulation was added to the diet. Addition of this carotenoid formulation to the diet increased the antioxidant power of the blood. Eggs produced by poultry fed diets supplemented by the formulation have in excess of 0.80 mg carotenoids per 100 grams of edible portion and thus serve as an important source of carotenoids in the human diet.
