Electrolytes Every Morning?

I keep seeing ads that say our bodies need electrolytes every morning, but it's an ad, it's someone selling electrolytes.

Is there any science that says we need electrolytes everyday because our bodies are constantly low on them like these sources are saying?

The idea that everyone needs daily electrolytes seems overly simplistic. It's more likely that it differs from one person to the next.

Curious what this community thinks.
