“At Doctor’s Best we’re 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.” according to the company’s website.
