DOCTORS' PREFERRED Berberine Supplement with Cinnamon & Chromium is a 90-tablet dietary supplement formulated to support nutrient processing, cellular energy, heart health, and lipid levels within the normal range, with 1,000 mg BerberPure Berberine and 250 mg OEA.
This formula is made for people seeking a supplement that brings berberine together with complementary ingredients in tablet form. Its stated purpose is to support the body's processing of nutrients, cellular energy, heart health, and lipid levels within the normal range. The formula combines its key ingredients with chromium picolinate and several botanical extracts.
Its key ingredients are intended to help the body process nutrients and energize cells while supporting heart health and lipid levels within the normal range over 12 weeks. The formula centers on BerberPure Berberine and OEA, with the amounts given for the product being 1,000 mg and 250 mg, respectively. These are support claims, not a promise of a particular outcome.
Alongside berberine and OEA, the supplement includes chromium picolinate, white mulberry, cinnamon, and banaba extracts. Together, these ingredients create a multi-ingredient formula rather than a berberine-only tablet. Cinnamon and chromium are also featured in the product name.
