Lutein is the most important nutrient part of the macular area of the retina. Lutein can protect the macula, promote the development of the macula, and relieve visual fatigue.
Lutein is a nutrient that is beneficial to the eyes, and moderate supplementation can improve vision and reduce symptoms such as eye fatigue. However, excessive intake of lutein may cause some *** such as allergies, gastrointestinal upset, etc.
In addition, the human body has a certain self-regulation ability and is able to synthesize some lutein on its own as needed. If you take lutein in large amounts uninterruptedly, it may weaken this self-regulatory mechanism, causing abnormal fluctuations in lutein levels in the body.
In order to maintain the optimal effects of lutein and reduce the body's adaptation.
It is recommended that 6-10 mg of lutein per day is safer, which ensures the quality of lutein required by the body without causing the risk of overdose. Of course, the specific needs may vary from person to person, and it is best to supplement under the guidance of a doctor.
It is generally recommended to supplement lutein after breakfast, because the stomach and intestines are in a state of hunger after a night of digestion, and the metabolism and absorption of lutein supplementation at this time are relatively fast.
In addition, spacing supplementation ensures that the body has sufficient time to digest and utilize the lutein ingested. It can be discontinued for a few days every few weeks. For example, you can take lutein for 5 days and then stop it for 2 days.
