primary mechanism
MCTs bypass the standard fat digestion pathway, absorbing directly into portal circulation and metabolised by the liver into ketone bodies (beta-hydroxybutyrate, acetoacetate).

What "safe" means here

Our safety scoring reflects (a) published clinical and observational literature on healthy-adult use at standard supplement doses, (b) the spectrum of adverse-event reports in the medical and supplement-pharmacovigilance record, and (c) the regulatory status across major jurisdictions. It does notreflect long-term outcomes in populations that haven’t been studied, and it does not substitute for clinical judgement applied to your individual situation.

A 5/5 score does not mean “no risk” — it means risk has been quantified as low in healthy adults at usual doses. Idiosyncratic and allergic reactions are possible with virtually any compound, including those we rate highest.
