Pure enzyme has no side effects. Experts say that the pharmacological effects of enzymes are completely different from those of general drugs. Enzyme is a kind of nutrient in the body, which will not produce side effects, and can be taken for a long time, which is helpful for the rehabilitation of serious diseases or incurable diseases. However, there are great differences among individuals. Some people are allergic to comprehensive enzymes, but the degree and frequency of reaction are very slight. But these symptoms are not caused by the side effects of enzymes. In short, as a good nutrient for the body, enzymes have no side effects. However, many enzymes on the market are fake and do not meet the safety standards, so be careful when purchasing. Precautions for taking enzymes According to the analysis, people with sensitive physique have allergic reactions to drugs in most cities, and those with mild reactions. If you want to continue taking enzymes, please pay attention to: 1. Try not to eat on an empty stomach. Eating after meals can make the stomach absorb slowly and the reaction will be reduced. There is no need to change the components. 2. If it still reacts after eating, then reduce the amount of enzyme by half. If there is still a slight reaction, the weight will be halved. According to practical experience, as long as the weight is halved, there will be no reaction. After the reaction disappears, the same amount can last for three days. Then gradually increase the weight and return to the original standard. It is best not to increase too much at a time. Some people with sensitive constitution will have an allergic reaction when they eat fruit. It is normal to have an allergic reaction when you start eating enzymes. When you get used to it, the reaction disappears. Later, you will find that eating fruit will not cause allergic reactions, and you are no longer allergic.
