Strategy is how a new health and wellness ingredient becomes a consumer mainstay instead of a passing fad. From ancient grains and superfoods to cannabidiol and collagen, and anything in between, Sam Dietle helps food, dietary supplement, and cosmetic companies navigate regulatory compliance for novel ingredients, uses, and products.

Sam advises on federal and state regulatory issues that arise at all stages of manufacturing foods and dietary supplements, with a focus on research and product development, claims substantiation, and premarket authorizations. She assists clients in conducting assessments of whether food ingredients are generally recognized as safe (GRAS), satisfying the new dietary ingredient notification (NDIN) requirements for dietary supplements, and developing strategies for bringing new food and dietary ingredients to market.

Sam helps clients differentiate their products in the marketplace while accurately communicating benefits to consumers and mitigating class action risk. She helps ensure marketing claims are based on appropriate data and substantiation in accordance with the U.S. Food and Drug Administration (FDA); Federal Trade Commission (FTC); and state labeling, advertising, and consumer protection laws. 

Since the 2018 Farm Bill altered the federal cannabis regulatory landscape in the United States, Sam has focused her efforts in counseling clients on the use of hemp-derived ingredients, such as hemp extract and CBD, in foods, dietary supplements, cosmetics, and other consumer products.

Sam is also committed to advancing social justice through her pro bono work. She served as a part of a Hogan Lovells team that represented immigrant women in their initial asylum proceedings in a family detention center in Dilley, Texas.
