Saccromyces might not be for everyone. Some caution might need to be used for people that have to much fungal candida. Check out this link:
“Kefir also demonstrated antifungal activity against Candida, Saccharomyces, Rhodotorula, Torulopsis, Microsporum and Trichopytonspecies.”
—Kefir is not going to kill candida or saccharomyces but rather produce acids that inhibit them from going fungal. These studies need to indicate what type of anti-fungal activity it is. Ant-fungal activity does not always mean cell death.
Anti-fungal activity could mean a variety of activities such as preventing virulence,inhibiting its fungal form, preventing growth, slowing down metabolism, etc…….
