Some collagen is fat, which will make you fat, while others have no fat content and will not make you fat. I recommend a collagen that not only won't get fat, but also can lose weight. It is called "delicious collagen jelly", which is the latest generation of collagen, fish collagen imported from Japan and collagen extracted from deep-sea fish skin in Japan. The quality is very good. The molecular weight of collagen is below 1000 dalton, which can be absorbed by human body 100%. Moreover, this kind of collagen adds a high-fiber plant "cold weather" with zero fat content. It can also play a role in slimming. What is even more unusual is that it is not the traditional unpalatable collagen, but the jelly-like collagen mixed with fresh orange juice and peach juice, which is sweet and sour and delicious. It is easy to carry and can be eaten anytime and anywhere.
