Which is better, lutein or carotene

Lutein is a type of carotene, and it also serves as a protective barrier for the eyes. If the intake is too little, it will often cause blindness. Carotene can remove free radicals from the human body and enhance immunity. So which one is better?

In fact, both have their own advantages.

Lutein is one of the main carotenoids in plasma and is evenly distributed in high-density lipoprotein and low-density lipoprotein. The lutein esters in food are converted into lutein through the combined action of bile and pancreatic lipase in the small intestine and absorbed by the small intestinal mucosa. Lutein, also known as "plant lutein", exists together with zeaxanthin in nature. It is the main component of plant pigments such as corn, fruits, vegetables, and flowers. It is also the main pigment in the macular area of ​​the human retina.

Lutein acts as a barrier for the tender eyes of infants and young children. Some people compare lutein to "invisible sunglasses", and I think this metaphor is quite accurate. It can be seen that lutein is particularly important for protecting human eyes.

Lutein, as an important antioxidant, is a member of the carotenoid family and is also known as "plant lutein". The human eyes contain high amounts of lutein, which cannot be produced by the human body and must be supplemented by lutein intake. If this element is lacking, the eyes will lead to blindness.

carotene

definition:

Carotene is an effective biological antioxidant that can remove free radicals in the body. It has the functions of improving the body's immunity, preventing cancer, atherosclerosis, thrombosis, and anti-aging. After being ingested into the human digestive organs, it can be converted into vitamin A. It is currently the safest product for supplementing vitamin A (simply supplementing with chemically synthesized vitamin A can cause poisoning in excessive amounts). It can maintain the health of eyes and skin, improve night blindness and rough skin conditions, and help protect the body from damage by free radicals. It should not be taken at the same time with acidic substances such as vinegar.

The role of carotene:

1. Help maintain the lubrication and transparency of the cornea and protect the health of the eyes;

2. It is one of the most effective antioxidants against harmful free radicals;

3. Strengthen the immune system and enhance the body's resistance.
