The hydroxypropyl methylcellulose (HPMC) used in our veggie capsules is derived from cellulose sourced from wood pulp. Specifically, it is sourced from softwood trees such as Pine and Spruce. This cellulose material is carefully processed to create the HPMC used in the manufacturing of our veggie capsules. We prioritize using high-quality and sustainable sources for our capsule materials to ensure the best possible product for our customers.
