If you don't take vitamin tablets for a long time, it is generally harmless to the human body. But the content of various vitamins in vitamin tablets is fixed. If a person's vitamin content is already high, it is possible to make up more if he continues to make up.

So I suggest:

First, try to get vitamins from your diet instead of taking any vitamin tablets.

Second, don't eat the same brand of vitamins for a long time.

Third, it is best to consult a doctor and make a plan according to your personal situation.

Taking vitamin tablets cannot replace vitamins in fruits and vegetables.

Because: because of the production process and storage time, the activity of some vitamins will decrease.

Some vitamins contain synthetic ingredients.

In short, a reasonable diet is the best source of vitamins. Only when there is a shortage will additional replenishment be considered.
