The observed abundance of 3He can be used, in conjunction with big bang nucleosynthesis, to set a lower bound to the density of nucleons in the universe. Critical to this approach is an estimate of the destruction of 3He in stars. Detailed stellar evolution calculations which explicitly examine 3He destruction are presented. The effect of stellar mass, composition, and mass-loss rate on 3He destruction is studied. Limits on 3He destruction appropriate for big bang nucleosynthesis and for understanding present interstellar 3He abundances are discussed.
