Take it with a grain of salt means check it

Take it with a grain of salt means don't believe it or be skeptical.

Meaning:

1) to understand that something is not completely true or right
2) not take something too seriously
3) accept, but with some reservations or skepticism
4) don’t exactly believe something

Nothing about checking it.

ThankQ y’all for clarifying the “grain of salt” phrase.
