We follow the evolution of ³He in stars of mass 0.8...10M_☉ for Pop. I and II compositions from the main sequence until advanced stages on the AGB. Under standard assumptions we confirm earlier results of more restricted investigations that low-mass stars up to 5M_☉ are net producers of ³He. We show that the inclusion of additional mixing due to diffusion beneath the convective envelope simultaneously leads to carbon isotope anomalies observed in globular cluster Red Giants and to a strong reduction of ³He, such that stars exhibiting such anomalies will have destroyed ³He contrary to the standard picture.
