So I finally found a pretty clear answer so putting it out here for anyone else pondering the same question:

"
Candida albicans, a yeast that commonly occurs in the gut, can use myo inositol as its primary food source. Overgrowth of this yeast can significantly alter bioavailability of myo inositol creating a scenario in which it would compete with its host, the human, for the nutrient. Giving a person myo inositol in a situation like this might initially help with symptoms but will ultimately lead to more yeast overgrowth in the gut making the situation worse.
