Below is the statement posted on our website regarding ingesting trehalose (not applicable to topical use of trehalose):
"Shortly after Glow15 was printed, a study in the journal Nature indicated that trehalose may potentially play a role in the rise of Clostridium difficile (commonly known as C diff), a bacterium that causes infection. Although the study is preliminary and not conclusive, I’m taking what I believe is a necessary precaution and not recommending trehalose be ingested until further evidence can confirm it’s safety. A healthy diet alternative is monk fruit sugar. There is no evidence to suggest topical trehalose is harmful. The study’s abstract is here."
Instead, we recommend monk fruit powder (which can be purchased at Whole Foods), and if that is not possible, honey if tolerated, or if you need to be sugar-free, a little real stevia.
