Does Tea Affect Benfotiamine?

May affect absorption or how you feel

The short answer

Tannins in tea reduce thiamine absorption. While benfotiamine is fat-soluble and more resistant than B1, tannins may still partially impair uptake.

How to arrange timing

Take benfotiamine at least 1 hour apart from tea.
