Excuse me, are American vitamin tablets suitable for China people? Will XX exceed the standard?

Yes, the so-called exceeding the standard means taking too much. If you can pay more attention to food collocation and eating rules, it is best to take it from food. If you need to add according to the instructions, nothing will be used. Generally, it can't meet the standard of overdose. Many people have eaten it. Keep taking it for a while, but don't expect too much from this multi-dimensional supplement, because the effect may not be obvious (different from person to person), and sometimes it may feel good and obvious for psychological reasons.
