The gradual progress of scientific research has brought new results to meet the most urgent needs. Scientists first discovered blueberry anthocyanins, which brought new hope to the eye care community. Blueberries are rich in antioxidant anthocyanins, which can effectively prevent eyeball aging, strengthen the elasticity of tear glands, supplement rhodopsin necessary for the retina, and enhance rhodopsin. Then there was another major discovery in the medical community, and lutein entered the field of vision of scientists. The discovery and application of lutein completely ushered in the era of eye care and nutritional supplements. Blueberry anthocyanins and lutein are the best visual nutrients currently discovered in the medical field, and can directly reach the fundus of the eyes. At the same time, it supplements two visual nutrients, which can effectively correct and help recover various eye diseases. There are blueberry lutein soft capsules and blueberry lutein ester compressed tablets currently on the market. You can judge which one is better based on the following points. Scientific research also promotes people's better intake and supplementation of these visual nutrients. With the application of lutein in the medical field and the further discovery of scientific research, there is a bioavailability problem in the intake of lutein. Scientific research has found that lutein exists in the form of "lutein ester" in nature. When lutein is extracted alone, its light and heat stability is extremely poor, and the stomach acidity is even worse when the human body ingests it. Lutein ester is very stable and can be naturally hydrolyzed into free lutein in the human body. The bioavailability of lutein in the small intestinal absorption process is 61.6% higher than that of lutein. The human body's intake of "lutein ester" can effectively supply the fundus of the eyes. Therefore, in 2008, the National Ministry of Health approved Lutein Esters as a functional new resource food in Document No. 12. The main active ingredients contained in blueberry lutein soft capsule are blueberry and lutein. The main functional ingredients of blueberry lutein ester tablets are: blueberry, lutein ester. It is recommended to choose blueberry lutein products with lutein ester as the main functional raw material. Another problem with the intake of blueberry lutein is the safety of product preparations. People who take blueberry lutein generally have serious eye problems or eye problems that require longer-term intake to correct. Then the safety of taking such product preparations is of great concern to consumers. Capsule-type products have problems with heavy metal content, so long-term use may cause harm to the body. Tablet candy chewable products can effectively avoid such problems. Regarding these two points: whether to choose blueberry lutein soft capsules or blueberry lutein ester compressed tablets, we will provide the majority of netizens with a basis for choice. Among such products, the products that have obtained national patents include the source-protecting lutein ester compressed tablets produced by the state-owned listed company North China Pharmaceutical. The formula ingredients are: blueberry, lutein ester, sorbitol, and mannitol.
