The Active Ingredient Is: Celery Seed Extract (3-n-Butylphthalide)

Celery seed extract comes from the seeds of the celery plant and is standardised to a high 3-n-butylphthalide content, the key active compound. This extract offers a botanical source of the active constituents for supporting circulatory health.

This form is a plant-based extract prepared from Apium graveolens seeds and is commonly supplied in a vegetarian capsule format as a standardized extract containing 3-n-butylphthalide. The extract may be accompanied by inert plant-derived carrier ingredients to facilitate capsule formation and stability.
