Transdermal Patch vs. Oral Supplement: The Evidence Gap, Explained

This site is direct about a specific evidence gap worth understanding: most of these ingredients are researched in oral form, not as a transdermal patch.

What the honest disclosure actually states

Berberine, Green Tea and Cinnamon each have their own studied history, mostly in oral form — this site doesn't claim the finished transdermal patch itself has been separately trialed.

Why this distinction matters for your expectations

Ingredient-level research supporting a general biological role is a different category of evidence from a clinical trial of this specific delivery method — worth understanding that gap honestly rather than assuming equivalence.
