01 / DESIGN

What was studied?

Fourteen healthy adults participated in a blinded crossover comparison of defined oral formulations, followed by a short single-arm safety phase.

02 / FINDINGS

What did the researchers report?

The micellar preparation produced higher measured blood exposure than the standard preparation under the tested conditions. Short follow-up did not identify significant changes in selected safety markers.

03 / LIMITS

How should it be interpreted?

Small formulation-specific pharmacokinetic findings do not establish long-term clinical benefit. Oral preparations and research-supply materials are not interchangeable.
