Do berberine patches work?
Berberine patches are designed to deliver berberine through the skin. The idea is appealing, but the key question is whether enough berberine reaches the bloodstream to have a meaningful effect.
At present, robust human research on berberine patches is limited. Most of the evidence relates to oral berberine, so a patch should not automatically be treated as equivalent. If you are considering berberine, choose a clearly labelled product, follow the directions and speak with a healthcare professional if you take medicines or have an underlying condition.
