1. People who are allergic to protein should not eat it.

2. People who have surgery, have a cold, or are menstruating are not allowed to eat isinglass for the time being. They should wait until they are discharged from the hospital after surgery, or after recovering from a cold, or after menstruation. This point was also mentioned in the article shared by Huanghaitang before, but many people misunderstood that it cannot be eaten. In fact, it is not that it cannot be eaten. It is better not to eat for the time being and eat after the symptoms have passed. This can more fully absorb nutrients and avoid waste. .

3. Within 3 hours after eating isinglass, do not drink tea, eat oranges, white radish and other things that will destroy the effect of isinglass. Eating isinglass requires an environment to allow the nutrients to be fully absorbed. This is related to the effect. Some people eat 20 grams and absorb only 1 gram. Some people eat 20 grams and absorb still 20 grams. This is 20 times the effect. There is a difference. Don't underestimate this.
