SwansonFull Spectrum Black Walnut Hulls

Black walnut hulls are the dried hull of the fruit of the black walnut (Juglans nigra), a tree native to North America. The hull has been used for centuries.

A Full Spectrum® formula means that the whole plant part is used, without extraction or processing. This keeps all the natural components in their original ratio.

The hull is a specific part of the black walnut, namely the outer shell of the fruit. This is different from the nut itself, which is often used in food.

Taking this supplement during or after a meal helps to digest the product better and may be gentler on the stomach. This is especially true for powdered herbal supplements, like black walnut hull.
