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.
