If 'stardust' strictly means elements created by stars (everything heavier than helium), what approximate portion of the human body mass qualifies?

Answer

Approximately 96% or more by mass

This figure is derived by subtracting the primordial hydrogen (about 9.5%) and trace primordial helium from 100% of the mass, leaving the vast majority as stellar products.
