I’ll take this with a grain of salt.

With the whole salt shaker.

Origin of “take it with a grain of salt”

A grain of salt (or a pinch of salt) is a very small piece of salt, so this idiom starts with the idea that most food tastes better with a little bit of salt. Food is tastier and therefore easier to swallow with a grain of salt, so this idiom claims that if someone is telling you something that is probably not entirely true or correct, it is easier to swallow it with a grain of salt than to argue against it.
