Does taking lutein help with dry eyes?It can be supplemented in moderation, but lutein alone is not enough, and lutein itself can be supplemented through diet. Lutein is also known as carotenoid, which is mainly converted into vitamin A in the human body to protect the eyes. Eyes need a variety of nutrients to be moisturized, the most important of which is vitamin B2; the process of vision requires the participation of vitamin A; the conduction of the optic nerve requires the help of B vitamins; preventing eye aging requires healthy blood vessels, and vitamin C and vitamin E are very helpful in this regard.

Egg yolk is also a good provider of lutein. The main purpose of lutein supplementation is because lutein can be converted into vitamin A in the body, so vitamin A can also be supplemented directly through diet. To supplement vitamin A, you should eat more liver, milk, egg yolks, green leafy vegetables, carrots, sweet potatoes, etc. Vitamin A is a fat-soluble vitamin. Excessive intake will be stored in the body. Excessive intake of lutein will cause an extra burden on the liver. The recommended daily dosage is about 12 mg. For example, if you eat animal liver, it is recommended to eat it once every three days, and don't eat too much each time.
