In addition, from the content and composition, we can also divide lutein into single lutein and compound lutein. The so-called compound lutein means that lutein not only contains lutein, but also contains other eye nutrients, such as anthocyanin, vitamin A, vitamin C, vitamin B 1, fish oil and so on.
Main considerations of lutein. Whether lutein brand refers to purchase and recommendation can be measured mainly from the following aspects.
1. If lutein is imported and sold in local hospitals and optometry centers, see if you have obtained formal import registration documents, such as eating health cards. If you have this license number, it means that this product has been approved by the Food and Drug Administration and has come in through legal channels, so consumers can buy it with confidence. Of course, at present, many imported lutein on the market have no approval, and even if there is approval, they are imported as ordinary food. Some consumers also choose Haitao lutein directly. This requires them to read each other's product information carefully when purchasing, and the risks need to be borne by themselves.
2. If it is domestic lutein, consumers should pay attention to whether the outer packaging bottle has "blue hat packaging" when choosing. If there is a blue hat sign, it means that this lutein has passed the clinical approval of the US Food and Drug Administration and can be purchased with confidence. Remind everyone that at present, the clinical certification of lutein is mainly to treat asthenopia in CDC, which shows that lutein is effective in improving asthenopia. If you have made other claims in other clinics, it means that it is a lie. If there is no formal approval of Blue Hat, consumers need to buy carefully and consult the channel clearly.
