Marshmallow root powder with empty capsules for capsule size guide

What Is Marshmallow Root?

Marshmallow Root is a traditional herbal ingredient commonly used in powders, teas, tinctures, and capsules. The root is naturally fibrous and fluffy when powdered, meaning it can take up more space inside capsules compared to dense extracts.

Because of this, choosing the correct capsule size is important for easier filling and fewer capsules per serving.
