Models accounting for the origin of lithium-7 in nucleosynthesis are compared, and it is argued that sufficient observational and theoretical data are available to determine the required minimum mass loss rate in super-lithium stars in order for steady mass loss to be a viable mechanism behind Li-7 galactic abundance. The model contains no adjustable parameters. One method uses observational data on the fraction of cool giants which are peculiar red giants, which are Li-rich, on Li abundance in super-Li stars, and on the space density of M giants. Determinations of mass loss rates in super-Li stars could either corroborate or eliminate the red giant model of galactic Li-7 origin. Another approach uses theoretical calculations of Li production in hot-bottom convective envelopes, and relies on the time integral of Li abundance. Slow mass loss from red giants is seen as a significant source of galactic Li-7.
