Berberine 800 mg from Enzymedica is for metabolic support.* Sustainably sourced from Barberry, with no artificial fillers or excipients, it is a metabolism-supporting powerhouse.* Berberine supports the body's natural metabolic processes and offers numerous benefits for overall health and wellness.* We use Berberis aristata in our Berberine capsules, standardized to 95%. This provides a consistent amount of Berberine with each and every serving. Berberine is a bitter compound called an alkaloid. Alkaloids help plants protect themselves against predators and regulate their growth. They also offer benefits for the overall health of humans.* You can find Berberine in plants like Goldenseal, Barberry, Oregon Grape and Goldthread. These plants have a long history of use in supporting health. Unfortunately, Goldenseal is an “at risk” plant due to overharvesting in the wild and its use is strongly discouraged by plant conservationists. Enzymedica's Berberine is sustainably sourced from barberry plants, which grow abundantly, and are naturally sustainable and rich in valuable phytochemicals. * These statements have not been evaluated by the Food and Drug Administration.
