ELI5: Why some drinks, especially vitamin drinks, say "drink it cold" on the packing?

English ain't my mother language, so the title might be a little off, but I'm sure you'll get it.

Food and drinks taste very different at different temperatures. Most people prefer to drink coffee hot, it's not nearly the same when it's warm or cool or cold. And beers are meant to be served room temperature, cool, or cold depending on their type because their flavour changes at different temperatures.

The drinks you refer to are designed to be served cold because that's the flavour that the manufacturers think is "best" for them.
