That’s a fascinating question! You are made almost entirely of ordinary matter (protons, neutrons, and electrons) and contain virtually no dark matter as a constituent part of your mass.
The actual mass of dark matter inside your body at any given moment is incredibly small, estimated to be around $10^{-22}$ kilograms (an incredibly tiny fraction of a gram). This is because dark matter doesn’t easily stick around or interact with ordinary matter like us.
However, you are constantly being streamed through by dark matter particles at very high speeds, similar to how countless neutrinos pass through you every second.
