Side effects of 13 1 enzyme, is the 13 1 enzyme on the market really a pure natural product without side effects?
Enzymes themselves are not naturally formed! As for the side effects, everything has side effects, just the number of people who attack! To put it bluntly, it is the probability size! Things that have absolutely no side effects basically do not exist! Even mineral water. Some people will have side effects! It's just that the probability is too low, and it's not completely absent, hehe!
