my best regards/respects to sb

[joham]

Give my best regards/best respects to your parents.

Dictionaries don't include the word 'best' in this expression. But if we do use it, does it sound natural?

Many thanks in advance.

How about warm regards?

[joham]

Thanks, Tdol. Then what about the adjective before the 'respects'?
Thank you again.

"Best regards" or only "regards" is used in AmE; "best respects" is not.
