Core Nutritionals is headed by drug-free pro bodybuilder Doug Miller, and his wife, drug-free pro figure competitor Stephanie Miller. Sick and tired of supplements that are built around hype and that simply do not work, Doug uses his biochemistry background to focus on producing superior products that are proven to work. Doug personally selects the most effective and highest quality ingredients for his line of supplements, and designs formulas to be effective for both elite and “weekend-warrior” athletes. Core Nutritionals always lets the consumer know exactly what is in its products and guarantees quality with rigorous testing. Also, all Core Nutritional products are manufactured in the U.S. and in cGMP facilities and free of any proprietary blends, fillers or artificial colors.
