David Winston's Iron Extract
David Winston's Iron Extract by Herbalist & Alchemist is a botanical supplement, categorized under Vitamins & Minerals. Each 2 mL serving contains 2.5 mL of a proprietary blend. The product's name suggests an iron-related benefit, but as a proprietary blend, the specific types and amounts of botanicals, and any actual iron content, are not disclosed. This lack of transparency makes it impossible to assess ingredient efficacy or clinical dosing. The product received an N+ Score of 45, earning an F grade, reflecting a below-average quality assessment by Nutrienting.com primarily due to the undisclosed ingredient breakdown. It is intended for individuals comfortable with proprietary botanical blends and general wellness support.
