The forward geometry of the LHCb detector provides unprecedented access to both the very high and very low regions of Bjorken \(x\) inside the nucleon. With full particle identification and a fast data acquisition (DAQ), LHCb is able to fully reconstruct plentiful charged particles and \(\pi^0\) mesons, as well as relatively rare probes such as \(Z\) bosons and heavy quarks, providing a unique set of constraints on nucleon structure functions. This talk will discuss recent LHCb measurements sensitive to intrinsic charm within the proton, modification of parton distribution functions inside the nucleus, and show the impact of recent LHCb measurements that dramatically reduce the nuclear parton distribution function (nPDF) uncertainties at low \(x\).
