Kryptonite is a compound consisting of the element krypton, according to chemical-forming "-ite" nomenclature of chemistry.
However, krypton is a planet where Superman Clark Kent comes from and the substance kryptonite from it due to the explosion is fatal to our Superman, i.e. the translucently green rocks you would see in the TV series and which make Clark Kent dizzy and feeble and can even kill him.
Thus figuratively, it means something that makes you weak, powerless and limp, i.e. your weakness, whenever it comes to you, because it can even weaken Superman, let alone you!
Just as the song "Kryptonite" in the Australian Idol Guy Sebastian's album where the lyrics go:
Cos I can't stop thinking of you
I'll be trying not to love you
I'm helpless, girl it's true
So I'm giving up tonight
Cos baby you're my "kryptonite"

***That girl's exactly Guy Sebastian's "kryptonite"!!
