Speaking of eye protection, lutein is definitely indispensable. It is a kind of carotenoid. So, it has an effect similar to vitamin A in protecting the retina and eyesight. The intake of it is related to eye health. The intake of the modern human diet is quite low. If you want to better protect your eyes, you still need to replenish them appropriately. So, how much lutein can you take a day?
For people with good eye conditions, a lutein supplement of up to 20 mg per day for adults should be safe. Is 40 mg of lutein too much? For people with eye problems such as macular degeneration and glaucoma, the recommended dosage range is 20mg-40mg/day. Most people know that if you want to supplement it, you can supplement with more yellow-green vegetables and fruits. If you consume more than 120g of green leafy vegetables per day, you may no longer need to take it else. If the intake of food supplements is relatively small, it is best to take them with dietary nutritional supplements. The dose is 6-10mg.
Can you overdose on lutein? There are no known side effects from taking too much of it. However, excessive supplementation will cause carotenemia, that is, skin discoloration. It may even hurt the liver. Therefore, the more dosage is not the better, it is better to take according to your own situation.
People are now very addicted to electronic products, leading to increased consumption of lutein, which leads to a lack of nutrition in the eyes. Food alone is not enough, so insist on taking it supplements to supplement eye nutrition.
