        Bottle of berberine 1,200 mg capsules with the label facing forward

        A label should tell you what is inside.

        In early 2024, the supplement maker NOW Foods reported that 5 of 12 creatine gummy brands it bought on Amazon or from brand websites contained little or no creatine. In a test NOW published in December 2023, 18 of 33 berberine brands sold on Amazon and Walmart.com had less than 40% of the berberine on their label.

        At Mavrena, every product page shows the Supplement Facts and every batch has a certificate of analysis.
