Doctor's Best




















Proven Science

Doctor’s Best is not interested in fads, trends, or quick fixes. We’re interested in science-based nutrition. We want to know what works, how it works, and why it works, well before we decide to manufacture or sell a product. We collaborate with nutritional scientists who are developing new ingredients, and we study their clinical findings to determine the most effective way to provide the desired results. 

Quality Ingredients

Doctor’s Best seeks out superior-quality ingredients that have been cultivated, studied, and developed all over the world. To deliver results consistent with research, we strive to use trademarked, branded ingredients in our products, matched to the specific ingredient and strength studied in the clinical studies. We then not only verify the quality of the raw materials used, but we test the finished product as well —added assurance that you’ll never find substitutes in Doctor’s Best. 

Education & Transparency

Doctor’s Best is committed to earning your trust through transparency and education. Sure we list all the ingredients on every bottle, describe how the product works, and cite studies that support product claims, but we give you much more than that. We provide easy-to-understand enhanced product pages—and a selection of videos—that can answer your most pressing questions: What is it? How does it work? Why should I take it? Looking for more scientific explanations? Check out our Scientific Fact Sheets, which are loaded with detailed background information, structure-function statements and scientific references that substantiate these statements. 

Manufacturing

Of course the integrity of the ingredients and the effectiveness of the product depend on the quality of manufacturing procedures. We choose our manufacturing facilities with care—only certified cGMP facilities pass our rigorous requirements—and we personally monitor every product throughout the production cycle to ensure it meets the highest quality standards.
