That's the basic reason for replying upstairs. Let me add something. Ejiao Guyuan cake evolved from the traditional Ejiao Guyuan paste, and its formula is the paste of Ejiao Guyuan paste. As said upstairs, Guyuan cake (paste) pays more attention to health care, and Ejiao is the main health care conditioner in its formula. The content of authentic Ejiao Guyuan cake will be higher than Ejiao cake. Of course, there are exceptions, that is, some manufacturers refer to Ejiao Guyuan cake as Ejiao cake for convenience. But no matter what it is called, if you want to choose authentic Ejiao Guyuan cake with high Ejiao content, you should choose products with high nutritional value in protein. Because the Ejiao Guyuan cake of this formula has high Ejiao content and high nutritional value. Because the main nutritional value of Ejiao is collagen and amino acids, including a variety of amino acids that the human body cannot synthesize itself.
