The difference between lutein ester and lutein

Feb 03, 2021

Now our eyes are occupied by electronic products every day. Even when we lie in bed at night, we are looking at mobile phones. Our eyes are overloaded. Lutein can protect our eyes, prevent myopia, and relieve visual fatigue. Now, there are lutein ester products on the market, which makes us a little confused in the choice. So what is the difference between lutein ester and lutein?

1, the absorption method is different: Lutein is mainly obtained from daily diet (corn, spinach, egg yolk, carrot, mango, kiwi, grape, orange, etc.), and it can be directly absorbed by the body in the intestine. However, lutein esters are extracted from marigold flowers, which are first decomposed in the human body and then converted into lutein before being absorbed by the body.

2, the difference in stability: the light and heat stability of lutein itself is not as good as lutein esters, so the utilization rate of lutein is also low. Lutein esters are more stable than lutein in terms of light and heat.

3, the difference in absorption rate: Lutein ester is much higher than lutein in absorption and utilization. Lutein ester is a fat-soluble lutein that has high biological activity in fat, so it is normal that the absorption rate of lutein ester is 60% higher than that of lutein.

4, the difference in acid resistance: Lutein is less resistant to gastric acid than lutein ester, which is easily dissolved by gastric acid and affects the body's absorption, while lutein ester is different. The consumption and loss of lutein esters ingested through the stomach is relatively low. Will not affect absorption.

5. The difference in absorption: The molecular structure of lutein ester and lutein are different, so at the same dose, the lutein that can be absorbed by the human body is twice that of lutein ester, and vice versa. With the same effect in the body, the dosage of lutein ester will be twice that of lutein.

Our eyes need 10 mg of lutein daily, which is equivalent to the intake of 13 catties of kiwi fruit or 6 catties of marigold. Eat more foods containing lutein in your life. If you have eye problems, you must seek medical treatment in time. For the relief of eye diseases, we must let the eyes work for a certain period of time to rest. The eyes are indispensable for us, so caring for the eyes is love Yourself.
