Mammal such as humans cannot synthesize lutein on their own and therefore must be obtained from food.Yeltein has a wide range of food sources and often exists in nature, which is the main component of plant pigments such as corn, vegetables, fruits and flowers.

Because its pure product is orange, we think that orange food content is rich, lutein is indeed in papaya, pumpkin, citrus, wolfberry, peaches and other orange fruits and vegetables, but the most abundant ingredients are in green leafy vegetables, such as kale, spinach, leek, cabbage, celery leaves, coriander, etc

The sources of lutein in animal foods are mainly milk and egg foods.Breast milk is the best source of lutein in infants, which is one of the important reasons for breastfeeding.Fresh milk and yogurt are all very good carriers of lutein.Although the content of eggs is not very high, but the bioavailability is good, almost three times the equal amount of vegetables.Lutein supplements can be used appropriately if found to lack lutein, or a lack of dark green leafy vegetables or orange fruits and vegetables for a long meal, or people using computers, mobile phones and TV for a long time.Yeltein has currently been listed as a dietary supplement.
