It depends on the material
If you have RF or Audio on a DC bias current you can wind bifilar and 
put equal DC down second wire to cancel the DC bias of your signal.
Then you are limited by Frequency and current.

Depending on the material, the higher the frequency, you can have more power

You can't know the saturation current for AC without knowing the core 
type and frequency.
