Patients are advised to take luteolin before breakfast, which can increase the absorption of the drug and make the drug fully effective. Since there is no influence of food and other factors before breakfast and luteolin has no obvious stimulating effect on the gastrointestinal tract, luteolin is more easily absorbed when taken at this time, which is the best time to take this medication. Lutein, also known as carotenoids, is an antioxidant that can resist cell and tissue damage caused by free radicals in the body and prevent aging of the body and cardiovascular sclerosis. In addition, lutein can also absorb blue light and other harmful light to protect the eyes, and can also promote the development of the retina in infants and children. In addition, during the period of taking lutein, patients should pay attention to the adjustment of diet, eat more foods rich in vitamin A, and also eat more animal liver, kidneys, coarse fiber food, etc. It should be noted that excessive lutein can cause certain damage to the liver, so it is recommended to take it on time and in the right amount under the guidance of a professional doctor.
