Each grain contains 20 mg of pure lutein, of which 800 mg of zeaxanthin, 100% is extracted from natural plant calendula. Lutein, a member of carotenoid family, is an essential component in macular area of eyes, which provides nutritional support for protecting eyes from sun damage and delaying eye aging. Lutein products are carefully produced by Nature's bounty, the classic brand of NBTY, the world's largest nutritional dietary supplement group, and 100% is imported from the United States.
Brief introduction of composition
Lutein is an important antioxidant, belonging to the carotenoid family (a group of natural fat-soluble pigments found in plants), and coexists with zeaxanthin in nature.
1, the main pigment component of retina.
Lutein and zeaxanthin constitute the main components of plant pigments such as vegetables, fruits and flowers, and are also the main pigments in human macular area. Human eyes are rich in lutein, which cannot be made by human body, and must be supplemented by lutein intake. Without this element, the eyes will be blind.
2. Protect eyes from light damage, delay eye aging and prevent lesions.
Ultraviolet rays and blue light in sunlight enter the eyes and produce a lot of free radicals. The outer layer of the macula of the eye is particularly vulnerable to oxidative damage by free radicals, so this area is easy to degrade, leading to cataracts and even cancer. Ultraviolet light can generally be filtered by cornea and lens, but blue light can penetrate the eyeball to reach retina and macula. Lutein in the macula filters out blue light like a filter to avoid the damage of blue light to the eyes.
3, anti-oxidation, help to prevent cardiovascular sclerosis, coronary heart disease and tumor diseases caused by aging.
Scientific anecdote: Britain found that lutein supplementation is good for eye health.
The Center for Ophthalmology and Neuroscience, University of Manchester, UK, conducted a clinical study on lutein supplementation in patients with age-related macular degeneration (AMD) aged 60-81year. After continuous supplementation of lutein 15 weeks, the pigment content in macular area of retina increased obviously, and the damaged retinal tissue was also repaired. Studies have shown that lutein supplementation can obviously improve age-related macular degeneration, at least in the early stage. The American Association for Ophthalmology Research and Control (EDCC) investigated 42 1 AMD patients and 6 15 disease-free groups, and concluded that the risk of AMD was significantly reduced in people with high serum carotenoid concentration. Because lutein, like carotenoids such as zeaxanthin, can also resist cell and organ damage caused by free radicals in human body, and can also prevent cardiovascular sclerosis, coronary heart disease and tumor diseases caused by human aging.
Instructions for selection of lutein soft capsules
Although the state has strict regulations on the content of heavy metals in capsule shell, it still contains some heavy metals. Heavy metals can easily enter human cells, causing damage to internal organs such as liver and kidney and DNA, which is carcinogenic and may induce gene mutation. (According to China Pharmacopoeia, capsule shell: the limit of chromium content is 2ppm(MK/KG)[2], lead content ≤0.5mg/KG, cadmium content ≤0.3 MK/KG, mercury content ≤0.2mg/KG and arsenic content ≤2.0 MK/KG). Consumers need to consider the duration of taking lutein products when choosing lutein-related products. Lutein products for children or patients with severe eye diseases need to be taken for a long time. (taking more than three quarters), it is recommended to choose products prepared by tabletting candy preparations, such as lutein ester tabletting products with the latest preparation method in the market. (The Ministry of Health approved lutein ester as a new resource functional food in document 2008 12).
Correct administration method of lutein capsules
1, capsule shell can't "eat by shelling". Eating without shell will not only affect the efficacy, but also burn the esophagus and cause stomach pain.
2, taking capsule lutein products, can not be taken with hot water, but with cold boiled water and warm water with lower temperature. Capsule shell is generally made of gelatin, which is easy to decompose after heating. Capsule shell gets stuck in the throat or esophagus, which is also easy to cause burns.
3, the amount of water should be sufficient to avoid drugs being blocked by "insufficient power" and stuck in the throat or esophagus. Be sure to stand or sit when taking medicine, and don't lie down immediately after eating, so as to ensure that the medicine can reach the gastrointestinal tract smoothly.
4. After taking the capsule, it is best to take another sip of water. If you feel foreign body sensation in the throat and esophagus, you can drink a glass of cold milk or warm water to reduce the damage of drugs to the pharynx and digestive tract.
Tip: What is macula?
Macula is located in the center of retina. Early anatomists called this area "macula" or "macula" because of its high lutein concentration and yellow color. Macula is the place where photoreceptor cells gather, which is responsible for providing the color and specific details of the center of the visual field. If there is no normal macular area, the main visual function will be gradually damaged until blindness.
Tip: How much lutein do you usually need to supplement?
It is reported that the dosage for preventing macular degeneration is at least 6 mg lutein per day. Lutein in supplements should be taken together with high-fat foods for better absorption.

How to protect your eyes
1, comfortable light, can get good visual information, too strong or too dark light will bring bad effects to the eyes. Therefore, the desk where teenagers usually read books should be equipped with side lights, in order to reduce reflection and damage to the eyes.
2. Teenagers read, write, watch TV and use the computer for hours without rest, and some students even go to bed late at night, which not only affects their health and makes their eyes overburdened, but also easily causes accommodative (or functional) myopia, that is, pseudomyopia. Moreover, the extraocular muscles will exert pressure on the scleral tissue of the eye wall, which will increase the intraocular pressure and make the intraocular tissue congested. Therefore, it is advisable for students to have a rest every 50 minutes when studying.
3. Don't hunch over, or read at your desk, let alone read sideways in bed. The distance between eyes and books should be 30-35cm, the distance between body and desk should be about10cm, and the angle between books and desk should be 30-45 degrees. If you put the book horizontally on the desktop, you should lean forward slightly when reading, so it is easy to move the book close to your eyes, which will increase the burden on your eyes by 2-3 times, thus causing fatigue of the neck muscles and the back of your neck. Unconsciously leaning forward for a long time will lead to decreased vision.
4. Try to reduce contact with TV, computers, game machines and other electrical equipment that have radiation to human eyes, because X-rays radiated by kinescope will consume a lot of rhodopsin in retina, which can obviously reduce vision. It is best to use LCD as a computer to reduce the harm of electromagnetic waves to the eyes. Students who often play video games are more likely to damage their vision, while students with low vision who play video games since childhood can't even correct their vision with glasses because of the impaired function of retina and macula.
5, work and rest time should be regular, and sleep should be sufficient. Lack of sleep can lead to conjunctival congestion, increased secretion, photophobia and tears, eye pain and other conjunctival and corneal inflammation. Should try to avoid sand, smoke, ultraviolet rays, infrared rays, chemicals, medical supplies and other injuries to the eyes. Personal hygiene should be kept clean, towels, washbasins, handkerchiefs and other personal items should be used by special personnel, and try not to use other people's items to avoid cross-infection, eye diseases and decreased vision.
6, nutrient intake should be balanced, partial eclipse or excessive intake of sugar and protein, resulting in the lack of zinc, calcium, chromium and other trace elements. , are not conducive to vision health. The prevention method is to eat more vegetables, fruits, liver, fish and other foods.
7. Some teenagers like reading while walking, or reading in the walking carriage, which is not good for their eyes, because the carriage is shaking and their bodies are shaking, and the distance between their eyes and the book can't be fixed. In addition, poor lighting conditions increase the burden on their eyes. It often causes myopia.
8. Doing eye exercises is a concrete manifestation of attaching importance to eye care in primary and secondary schools in China. By massaging acupoints and muscles around the eyes, nerve endings can be stimulated, blood circulation around the eyes can be increased, and eye metabolism can be adjusted, thus eliminating fatigue, enhancing eyesight and preventing myopia. In addition, more exposure to natural scenery such as green mountains and green waters is also beneficial to the health of the eyes.
