Lutein itself is an antioxidant and can absorb harmful light such as blue light. Coexisting with zeaxanthin in nature, it is the main component of plant pigments such as corn, vegetables, fruits and flowers.

BENEFITS OF LUTEIN AND ZEAXANTHIN
1. Protect vision:
They have an important protective effect on the macula in the retina, and its deficiency can easily lead to macular degeneration and blurred vision. Then appear vision degradation, myopia and other symptoms. and they are natural antioxidant that can effectively prevent the formation of free radicals and avoid the damage of free radicals to vision. And lutein can absorb a lot of damaging blue light to the eyes, to avoid the light caused oxidative damage to the glasses.
2. Antioxidant action
The strong oxidation of them can inhibit the activity of active oxygen free radicals, prevent the damage of active oxygen free radicals to normal cells, so as to protect the body from damage and enhance the immune capacity of the body.
3. Delay arteriosclerosis
The low content of lutein in blood is very likely to cause arterial wall thickening. With the gradual increase of lutein content, the trend of arterial wall thickening decreases, and arterial embolism is also significantly reduced. At the same time, Xanthoxylum in arterial wall cells can also reduce the oxidation of LDL cholesterol.
4. Anticancer effect
Lutein has an inhibitory effect on a variety of cancers, such as breast cancer and skin cancer. Higher intake of lutein can not only inhibit the swelling of cancer but also play a role in the prevention of tumor.
5. Natural coloration
Lutein and zeaxanthin are important natural colorant, mainly found in marigold chrysanthemum, zeaxanthin, spinach, broccoli, pumpkin, etc. It has a yellow-orange appearance. Theycan not only be used for paper making, but also for food coloring and added to poultry feed.
WORK PRICIPLE OF LUTEIN
Lutein can absorb blue light, reduce the eye’s exposure to harmful light, and form part of the macula area. The macula is a small area of the retina that is the most sensitive place in the eye and the most vulnerable to trauma. Lutein helps protect the retina from excessive exposure to ultraviolet and blue light, slowing the aging process of the eye.
How much lutein should I eat every day?
The human body cannot synthesize lutein and zeaxanthin, so these nutrients must be supplemented by food every day, if the food supplement is not enough, or in a specific physical condition, food supplement alone can not meet the requirements, should be under the guidance of a doctor or nutritionist, a reasonable choice of dietary supplements.
The specific recommended value for lutein in adults is 10mg per day.
The maximum tolerable intake is 40mg per day.
