Is lutein in maternal and infant shop useful?

I recommend that you give priority to lutein ester. Compared with lutein, lutein ester has higher efficiency, higher purity and less loss. Before I went to the store, I was attracted by the packaging of Dr. Duo's lutein ester pills at first sight. The clerk told me that it was a patented lutein ester, and the quality was extremely high. It hasn't let me down after buying it for so long. Blinking used to be uncomfortable, but now it's much better. My family has been eating.
