What is it

Eschsoltzaxanthone (likely intended as eschscholtzxanthin) is a carotenoid found in California poppy (Eschscholzia californica) and related plants. It is uncommon as an isolated supplement ingredient.

How it works

As a carotenoid, eschscholtzxanthin contributes color and antioxidant activity to the parent plant. The clinical pharmacology of the isolated compound in humans has not been characterized in published research. Most research on Eschscholzia californica focuses on its alkaloid content (protopine, californidine) and its traditional use for mild anxiety and sleep support.

Dosage

There is no established daily intake recommendation for isolated eschscholtzxanthin. California poppy extract supplements typically deliver 100 to 500 mg per day.

When and how to take it

California poppy is typically used in the evening for relaxation or sleep support. Carotenoids generally do not have time-of-day requirements.
