First, we need to know the source of lutein. Lutein mainly exists in green vegetables and fruits. It is a natural nutrient with antioxidant and eye protection effects. Therefore, when choosing lutein products, you can pay attention to those brands that emphasize natural ingredients, such as Unisys or Novolas with Nordic formula. Remember not to choose chemically synthesized and unmarked.
Secondly, you can know whether the ingredients are reliable by looking at the ingredient list of the product. Some well-known brands will clearly mark the content of lutein and the addition of other nutrients in the ingredient list, so that consumers can understand the ingredients of the products more transparently.
Ps: If it is difficult for us ordinary people to understand the difference between these ingredients, we can find some officially certified brands. For example, the Nordic formula Novolas mentioned above, whose lutein is Lutemax2020? Patent lutein, in line with non-GMO, FDA, USP, GRAS and other authoritative certification. Another astarot? Patented astaxanthin is also a component with USP Pharmacopoeia certification, ISO900 1 certification and other certifications, which is very reliable.
Finally, it is best not to blindly follow the trend, and good product ingredients can withstand deep scraping.
