Establishing a comprehensive model of cosmic rays is crucial for the search for antimatter or dark matter signals within cosmic radiation. Although cosmic rays were discovered over a century ago, the development of an exhaustive model capable of explaining their origin, acceleration mechanism, and propagation through the Galaxy has been hindered by a lack of precision data. Over the past 15 years, the AMS experiment—operating on the International Space Station in near Earth orbit—has provided precision data on cosmic-ray particles, antiparticles, and nuclei ranging from hydrogen to nickel, including the isotopic composition of light nuclei from hydrogen to beryllium. I will present the key results obtained by AMS on nuclei and isotope fluxes and discuss their impact on our understanding of the origin, acceleration, and propagation of cosmic rays through the Galaxy to the vicinity of Earth.
