Top 10 herbal supplement manufacturers

Our ranked picks for the herbal supplement makers we trust most — judged against eight quality standards. The list is editorial: based on certifications held, transparency of sourcing, formulation quality, and reputation among practitioners.

Last reviewed April 2026. Re-reviewed at least annually as brands change ownership, formulations, or certifications.

The 8 standards we check

Each brand is graded against the eight badges below. Filled green = the brand holds that standard across most or all of their herbal line. Gray = they don't hold it (or only on a small subset of products).
